Best CGM Devices for Diabetes Management

A continuous glucose monitor (CGM) is one of the most useful tools available for managing diabetes, replacing routine finger-prick checks with a steady stream of real-time glucose data. In the UK, the best CGM for you depends on your diabetes type, whether you use insulin, whether you want a device that connects to an insulin pump, and how you access it. The leading options are the FreeStyle Libre family (Libre 2 Plus and Libre 3 Plus) and the Dexcom family (Dexcom ONE+, G6 and G7), with newer arrivals such as the implantable Eversense 365 expanding the choice further.

This guide explains the best CGM devices by use case, how they compare, and how NHS access works, so you can have an informed conversation with your diabetes team. If you are new to glucose monitoring, our overview of blood glucose testing options is a helpful starting point.

The best CGM devices in detail

One of the biggest concerns during summer is dehydration.
When the body loses fluids through sweating, glucose becomes more concentrated in the bloodstream. This can contribute to higher blood sugar readings.
Signs of dehydration include:

Dry mouth
Excessive thirst
Fatigue
Headaches
Dark urine

Drinking water regularly throughout the day is especially important during hot weather.

*Strongest when correcting a genuine magnesium deficiency.

The best CGM devices in detail

FreeStyle Libre 3 Plus: best for wear time and value

The FreeStyle Libre 3 Plus is Abbott’s flagship sensor and one of the smallest CGMs available, roughly the size of two stacked pennies. It sends a glucose reading to your phone every minute, lasts up to 15 days, and offers optional real-time alarms. Its long wear time and competitive price make it a strong value choice, and it can link with several compatible insulin pumps for a hybrid closed-loop setup. The earlier FreeStyle Libre 3 remains widely used and offers the same core experience.

Dexcom G7: best all-rounder for accuracy and alerts

The Dexcom G7 pairs excellent accuracy (around 8.2 percent MARD) with a fast 30-minute warm-up, customisable alerts, and predictive low-glucose alerts that warn you before you go low. It lasts 10 days with a 12-hour grace period, tolerates being submerged in water for longer than most rivals, and integrates more widely with insulin pumps and automated insulin delivery systems. It is often the best pick for intensive insulin management or anyone with impaired hypoglycaemia awareness.

FreeStyle Libre 2 Plus and Dexcom ONE+: best NHS starter options

These two lower-cost formulary devices are the most widely prescribed CGMs on the NHS, and they meet the needs of most people who qualify. The FreeStyle Libre 2 Plus offers 15-day wear, optional alarms, and data sharing. The Dexcom ONE+ offers 10-day wear, a 30-minute warm-up, repeat low-glucose alerts, and data sharing with up to 10 followers. Both are excellent, dependable entry points to continuous glucose monitoring.

Eversense 365: best for long-term, low-maintenance wear

The Eversense 365 is an implantable CGM whose sensor is placed under the skin of the upper arm by a healthcare professional and lasts up to a year, with a removable transmitter worn on top. It removes the routine of changing sensors every couple of weeks, though it requires a small insertion and removal procedure. Availability in the UK is more limited than the patch-based systems, so it is worth asking your specialist team whether it is an option for you.

How to choose the right CGM

There is no single best CGM for everyone. The right choice comes down to a few practical questions:

Do you use insulin, especially with a pump? If so, prioritise pump compatibility. The Dexcom G7 has the broadest integration.
Do you need strong hypo protection? Predictive low alerts, as on the Dexcom G7, give you warning before a low.
Is cost or wear time your priority? The FreeStyle Libre 3 Plus offers long wear and good value.
Do you prefer minimal fuss? A widely available NHS option such as the Libre 2 Plus or Dexcom ONE+ may be all you need.

Whichever you choose, it is sensible to keep a backup meter and a supply of test strips for the times a CGM reading does not match how you feel or glucose is changing quickly.

Getting a CGM on the NHS

NHS eligibility is guided by NICE and your local Integrated Care Board. Broadly, everyone with type 1 diabetes should be offered a CGM, and people with type 2 diabetes on insulin may also qualify. Lower-cost devices such as the FreeStyle Libre 2 Plus and Dexcom ONE+ are the usual starting point, while higher-cost devices such as the FreeStyle Libre 3 and Dexcom G7 are reserved for specific clinical needs and are often initiated by specialist teams. Note that Dexcom is phasing out the older G6 in favour of the G7. If you do not qualify for NHS funding, sensors can be bought privately from registered pharmacies.

Conclusion

The best CGM is the one that fits your diabetes type, your treatment, and your daily life. The Dexcom G7 is the strongest all-rounder for accuracy, alerts, and pump integration, while the FreeStyle Libre 3 Plus leads on wear time and value, and the Libre 2 Plus and Dexcom ONE+ are dependable, widely available starting points. You can explore CGM sensors and diabetes monitoring supplies through the Diabetes Pharmacy online shop, and if finger-prick testing is still part of your routine, meters that do not need test strips can make regular checks simpler to sustain.

FAQs

What is the most accurate CGM?
The Dexcom G7 and FreeStyle Libre 3 Plus are among the most accurate CGMs available, both with a MARD of around 8 percent. Accuracy is very close between the leading devices, and all are clinically reliable for everyday diabetes decisions when used as directed.
Which CGM lasts the longest?
Among patch sensors, the FreeStyle Libre 2 Plus and Libre 3 Plus last up to 15 days, compared with 10 days for Dexcom sensors. The implantable Eversense 365 lasts far longer, up to a full year, but requires a clinician to insert and remove it.
Can I get a CGM if I have type 2 diabetes?
Possibly. On the NHS, CGM is generally funded for type 2 diabetes when you are on insulin, though criteria vary locally. If you do not qualify, you can still buy a CGM privately, which some people with type 2 diabetes or prediabetes use to understand how food and activity affect their glucose.
Do CGMs replace finger-prick testing completely?
Mostly, but not entirely. Modern CGMs are factory calibrated and do not need routine finger-prick calibration, but you should still confirm with a meter and test strips when a reading does not match your symptoms or glucose is changing rapidly.
Which CGM works with an insulin pump?
Several do, but compatibility is specific. The Dexcom G7 has the broadest integration with pumps and automated insulin delivery systems, and some FreeStyle Libre sensors also connect with compatible pumps. Always check that your particular pump and sensor are approved to work together.

Supplements to Reduce Blood Sugar: What the Evidence Actually Shows

If you live with type 2 diabetes or prediabetes, you have probably wondered whether a supplement could help bring your blood sugar down. The honest answer is nuanced. A small number of supplements, most notably berberine, cinnamon, magnesium, alpha-lipoic acid and chromium, have shown modest, measurable effects on fasting glucose or HbA1c in clinical trials. None of them, however, is a replacement for medication, diet, exercise, or regular blood glucose monitoring.

This guide explains what the research shows for each supplement, typical studied doses, safety considerations, and how supplements fit alongside proven diabetes management. Always speak to your GP, pharmacist, or diabetes team before starting anything new, especially if you take glucose-lowering medication.

First, the foundations that actually work

No supplement outperforms the core pillars of blood sugar control: a balanced diet, regular physical activity, adequate sleep, medication taken as prescribed, and consistent monitoring so you can see what is working. If you would like practical, everyday changes to build on, our guide to everyday habits that keep blood sugar stable is a good place to start. Supplements should be viewed as a possible add-on at the margins, not the main strategy.

Because the effects are small, the only reliable way to know whether a supplement is helping you is to measure. A finger-prick meter or a continuous glucose monitor (CGM) lets you compare readings before and after a trial period of 8 to 12 weeks.

The supplements with the strongest evidence

1. Berberine

Berberine is a compound extracted from plants such as barberry and goldenseal, and it has the most consistent human evidence of any supplement on this list. A 2022 meta-analysis of 37 randomised trials (3,048 participants) found that berberine reduced fasting plasma glucose by about 0.8 mmol/L and HbA1c by roughly 0.6 percent, an effect that, in some trials, was comparable to metformin.

Typical studied dose: 900 to 1,500 mg per day, usually split across meals, for one to three months. Safety: berberine commonly causes digestive upset, such as diarrhoea, cramping, or constipation, and it can interact with many medications. It should be avoided in pregnancy and breastfeeding.

2. Cinnamon

Cinnamon may modestly improve insulin sensitivity and lower fasting glucose, though trial results are mixed. Two forms exist: Cassia (the common supermarket type, which is more studied but higher in coumarin) and Ceylon (“true” cinnamon, which is lower in coumarin). High-dose Cassia taken over long periods can stress the liver, so keep doses moderate.

Typical studied dose: 1 to 6 g per day. It is best treated as a minor, optional adjunct rather than a core intervention.

3. Magnesium

Magnesium deficiency is common in people with type 2 diabetes, and correcting a genuine deficiency appears to improve insulin sensitivity. The benefit is clearest when you are actually low in magnesium. Supplementing beyond your needs is unlikely to help and can cause diarrhoea. Dietary sources include leafy greens, nuts, seeds, and whole grains.

Typical studied dose: 250 to 350 mg per day of elemental magnesium. Safety: high doses can cause loose stools, and caution is needed with kidney disease.

4. Alpha-lipoic acid (ALA)

Alpha-lipoic acid is an antioxidant most valued for easing the symptoms of diabetic peripheral neuropathy (nerve pain), with meta-analyses also reporting modest reductions in fasting glucose and HbA1c. It is one of the better-supported options where nerve discomfort is a concern.

Typical studied dose: 300 to 600 mg per day. Safety: it is generally well tolerated, but it may add to the glucose-lowering effect of medication, so monitor for lows.

5. Chromium

Chromium, usually taken as chromium picolinate, plays a role in how the body uses insulin. The evidence is weak and inconsistent, but some trials show small improvements in fasting glucose, particularly in people with a deficiency. Note that chromium picolinate is not interchangeable with other chromium forms used in research.

Typical studied dose: 200 to 1,000 mcg per day. Safety: it is generally safe at typical doses, but it can interact with thyroid medication and some others.

Others with weaker or mixed evidence

Gymnema sylvestre: the Ayurvedic “sugar destroyer,” studied for reducing sugar absorption and cravings.
Fenugreek: a soluble fibre that may blunt post-meal spikes.
Bitter melon: contains insulin-like compounds, though trial quality is generally low.
Vitamin D: correcting a deficiency may support insulin function, but supplementing when levels are normal shows little benefit.

Dehydration and High Blood Sugar

Dry mouth
Excessive thirst
Fatigue
Headaches
Dark urine

Drinking water regularly throughout the day is especially important during hot weather.

At-a-glance comparison

The table below summarises how the main options compare. “Evidence strength” reflects the consistency and quality of human trials, not the size of the effect.

Supplement	Evidence	Typical studied dose	Key cautions
Berberine	Strongest	900 to 1,500 mg/day, split	GI upset; many drug interactions; avoid in pregnancy
Alpha-lipoic acid	Moderate	300 to 600 mg/day	Watch for lows alongside medication
Magnesium	Moderate*	250 to 350 mg/day	Benefit mainly if deficient; caution in kidney disease
Cinnamon	Mixed	1 to 6 g/day	Cassia is high in coumarin; keep doses moderate
Chromium	Weak	200 to 1,000 mcg/day	Interacts with thyroid medication

*Strongest when correcting a genuine magnesium deficiency.

Using supplements safely

Because several of these supplements can lower blood sugar, combining them with insulin or medications such as sulphonylureas raises the risk of hypoglycaemia. Here are a few practical safeguards:

Talk to your pharmacist or GP first, especially about interactions with your current prescriptions.
Introduce one supplement at a time so you can tell what is actually having an effect.
Measure before and after. Use a meter or CGM over an 8 to 12 week trial and look at fasting and post-meal readings.
Choose quality products that state the specific form and dose used in research, such as berberine HCl.

Keeping testing consistent does not have to be expensive. Our guide to affordable blood sugar testing in the UK explains how to keep monitoring costs down, and if handling strips is a barrier, strip-free meter options can make regular checks easier to sustain.

Conclusion

Supplements are not a shortcut, and they are not a substitute for treatment. Berberine and alpha-lipoic acid have the most convincing evidence, magnesium helps mainly when you are deficient, and cinnamon and chromium are minor players at best. Any real-world benefit is modest and only appears when a supplement is paired with the fundamentals: good food, movement, prescribed medication, and regular glucose monitoring.

If you decide to trial one, do it with your healthcare team’s input and track the results. You can explore blood glucose meters, test strips and CGM sensors through the Diabetes Pharmacy online shop to measure whether a supplement is genuinely making a difference for you.

FAQs

What is the best supplement to lower blood sugar?
Berberine has the strongest and most consistent clinical evidence, with meta-analyses showing reductions in fasting glucose and HbA1c that were comparable to metformin in some trials. However, it can cause digestive side effects and interacts with many medications, so it should only be used with medical guidance.
Can supplements replace diabetes medication?
No. No supplement is proven to replace insulin or oral diabetes medication. Supplements may offer a small additional benefit at best, and they should never be used instead of a treatment plan agreed with your healthcare team.
How long before a supplement shows an effect on blood sugar?
Most clinical trials run for 8 to 12 weeks. If you trial a supplement, monitor your fasting and post-meal readings across that period with a meter or CGM so you can objectively see whether it is helping.
Are blood sugar supplements safe to take with metformin?
Some, such as berberine, can add to metformin’s glucose-lowering effect and increase the risk of hypoglycaemia or digestive side effects. Always check with your pharmacist or GP before combining supplements with any prescription medication.
Does cinnamon really lower blood sugar?
Some studies show that cinnamon can modestly improve fasting glucose and insulin sensitivity, but the results are inconsistent. If you use it, keep doses moderate, especially with Cassia cinnamon, which is high in coumarin and can affect the liver at high intakes.

How Weather Changes Can Affect Blood Sugar Levels

Most people with diabetes understand that food, medication, and exercise can influence blood glucose levels. However, one factor that is often overlooked is the weather.

Changes in temperature, humidity, and seasonal conditions can affect how your body responds to insulin, physical activity, hydration, and even glucose monitoring devices. Understanding these effects can help you make better decisions throughout the year and maintain more consistent blood sugar control.

Can Weather Really Impact Blood Sugar?

Yes. Both hot and cold weather can affect blood glucose levels in different ways.
Your body’s response to temperature changes may influence:

Insulin sensitivity
Hydration levels
Physical activity patterns
Appetite and eating habits
Medication effectiveness
Blood circulation
While the impact varies from person to person, many people with diabetes notice changes in their glucose readings during seasonal transitions.

How Hot Weather Can Affect Blood Sugar

Warm temperatures can increase blood flow, which may cause insulin to be absorbed more quickly than usual.
This can sometimes lead to:

Lower blood sugar levels
Increased risk of hypoglycaemia
Faster insulin action
Greater glucose fluctuations

Hot weather may also encourage outdoor activities, which can further lower blood sugar levels.

Dehydration and High Blood Sugar

Dry mouth
Excessive thirst
Fatigue
Headaches
Dark urine

Drinking water regularly throughout the day is especially important during hot weather.

How Cold Weather Can Affect Blood Sugar

Cold temperatures can create different challenges.
When the body becomes cold, it releases stress hormones that help maintain body temperature. These hormones may cause blood glucose levels to rise.
Cold weather may also lead to:

Reduced physical activity
Increased comfort eating
Less time spent outdoors
Higher insulin resistance

For some people, winter months can result in higher average glucose readings.

Seasonal Illnesses and Blood Sugar

Colds, flu, and seasonal infections are more common during certain times of the year.

When you’re unwell, your body releases hormones to fight infection. These hormones can increase blood sugar levels even if you’re eating less than usual.

During illness:

Monitor glucose more frequently
Stay hydrated
Follow your healthcare provider’s sick-day guidance
Continue monitoring for signs of hyperglycaemia

Humidity Can Make a Difference

High humidity can increase the body’s difficulty cooling itself.

As a result:

Sweating may increase
Dehydration risk may rise
Glucose management may become more challenging
People who use Continuous Glucose Monitoring systems may also notice that excessive sweating occasionally affects sensor adhesion.

How Weather Affects Physical Activity

Weather often influences exercise habits.

During warmer months, many people:

Understanding Blood Sugar Spikes: Causes, Symptoms, and How to Prevent Them

Managing blood sugar levels is one of the most important aspects of diabetes care. While occasional fluctuations are normal, frequent blood sugar spikes can make diabetes management more challenging and may increase the risk of long-term health complications.

Many people living with diabetes experience unexpected rises in glucose levels, even when they believe they are following a healthy routine. Understanding what causes blood sugar spikes and learning how to manage them can help improve glucose control and overall well-being.

What Is a Blood Sugar Spike?

A blood sugar spike, also known as hyperglycemia, occurs when glucose levels rise above the target range. This typically happens after eating, but it can also be triggered by stress, illness, medication changes, or reduced physical activity.

For people with diabetes, repeated spikes can make it more difficult to maintain healthy glucose levels and may affect long-term health outcomes.

Common Causes of Blood Sugar Spikes

Several factors can contribute to sudden increases in blood sugar levels.

High-Carbohydrate Meals

Carbohydrates have the greatest impact on blood glucose levels. Foods such as white bread, sugary drinks, pastries, and processed snacks can cause rapid increases in blood sugar.

Even healthy carbohydrate sources may contribute to spikes if portion sizes are too large.

Lack of Physical Activity

Exercise helps the body use glucose more efficiently. Long periods of inactivity can make it harder for cells to absorb glucose, leading to higher blood sugar levels.

Stress and Anxiety

Physical and emotional stress can trigger the release of hormones such as cortisol and adrenaline. These hormones may increase blood glucose levels, even without changes in diet.

Illness or Infection

When the body is fighting illness, it often releases additional hormones that can raise blood sugar levels. This is why glucose monitoring becomes especially important during periods of sickness.

Medication Factors

Missing diabetes medication doses or taking medications incorrectly can contribute to elevated blood glucose levels.

Some non-diabetes medications may also affect glucose control.

Poor Sleep

Research has shown that inadequate sleep may affect insulin sensitivity and contribute to blood sugar fluctuations.

CGM vs Finger-Prick Testing: When Do You Still Need Both?

Continuous glucose monitoring has transformed the way many people manage diabetes. Instead of relying solely on occasional blood glucose checks, modern CGM systems provide a continuous stream of glucose data throughout the day and night.

Devices such as Libre Sensors make it easier to spot glucose trends, understand how food and activity affect blood sugar levels, and receive alerts before glucose levels become too high or too low.

However, despite the growing popularity of CGM technology, finger-prick testing still has an important role to play. The question is no longer whether CGM is better than finger-prick testing, but rather when each method is most useful and why many people still benefit from using both.

Why CGM and Finger-Prick Results Can Differ

One of the most common questions people ask is why their CGM reading sometimes differs from a finger-prick result.

The answer lies in how each technology works.

A finger-prick test measures glucose directly from a blood sample, while a CGM sensor measures glucose levels in the interstitial fluid beneath the skin. Because glucose takes time to move between blood and interstitial fluid, there can be a short delay between the two readings.

This difference is often most noticeable after meals, during exercise, or whenever glucose levels are rising or falling quickly.

That is why healthcare professionals often recommend keeping a blood glucose meter and compatible Test Strips available, even when using a CGM system.

When Do You Still Need Both?

When Symptoms Don’t Match Your Sensor Reading

If your CGM shows a normal reading but you feel symptoms of low or high blood sugar, it may be wise to perform a finger-prick test.

Although systems such as Libre Sensors are highly accurate, there are situations where a direct blood glucose reading can provide additional reassurance.

During Rapid Glucose Changes

CGM technology performs exceptionally well for monitoring trends. However, when glucose levels are changing quickly, sensor readings may briefly lag behind blood glucose levels.

A finger-prick test can help confirm your current glucose level before making treatment decisions.

When Treating Hypoglycaemia

Many people choose to confirm a low glucose alert using a blood glucose meter before treating a suspected hypo, particularly if symptoms are mild or unexpected.

Keeping Test Strips readily available ensures you can perform a quick confirmation check when needed.

As a Backup for Sensor Issues

No technology is perfect.

Sensors can occasionally become dislodged, fail unexpectedly, or require replacement. In these situations, a traditional blood glucose meter remains an important backup.

This is one reason many users of Libre Sensors continue to keep testing supplies available at home and while travelling.

What CGM Does Better

The greatest strength of CGM technology is its ability to show the bigger picture.

Rather than displaying a single reading, CGM systems reveal trends, patterns, and fluctuations throughout the day.

People using Libre Sensors can monitor glucose levels during sleep, exercise, meals, and daily activities without performing multiple finger-prick tests.

This broader perspective can help users identify recurring patterns and make more informed diabetes management decisions.

What Finger-Prick Testing Does Better

Finger-prick testing remains the most direct way to measure blood glucose at a specific moment.

While CGM provides trend information, a blood glucose meter can offer confirmation when:

Symptoms and sensor readings do not match
Glucose levels are changing rapidly
A sensor issue is suspected
A healthcare professional recommends confirmation testing

This is why many diabetes management plans continue to include both CGM devices and compatible Test Strips.

Practical Examples

Imagine someone wearing Libre Sensors notices their glucose trend arrow pointing downward before lunch.

Although the reading appears safe, they begin feeling shaky and unwell. A finger-prick test confirms that blood glucose levels have dropped lower than expected, helping them take appropriate action quickly.

In another example, a person receives a low glucose alert while driving preparations are underway. Before making treatment decisions, they use a meter and Test Strips to confirm the result.

In both situations, CGM provides valuable awareness while finger-prick testing offers additional confidence.

Benefits and Considerations

Using both CGM and finger-prick testing creates a more complete monitoring approach.

CGM systems provide:

Continuous glucose visibility
Trend analysis
Alerts and notifications
Reduced routine finger-prick testing

Finger-prick testing provides:

Direct blood glucose readings
Confirmation during critical situations
Backup monitoring when sensors are unavailable

For many people, combining Libre Sensors with a supply of compatible Test Strips offers the best balance between convenience and accuracy.

Final Verdict

Continuous glucose monitoring has made diabetes management more convenient and informative than ever before. Devices such as Libre Sensors provide valuable real-time insights that help users understand their glucose patterns throughout the day.

At the same time, traditional blood glucose testing continues to play an important supporting role. Keeping compatible Test Strips available ensures you can verify readings when needed and maintain confidence in your diabetes management decisions.

Rather than viewing CGM and finger-prick testing as competing technologies, it is often more accurate to see them as complementary tools that work together to support safer and more effective glucose monitoring.

FAQS

Do I still need finger-prick tests if I use Libre Sensors?
Possibly. Although Libre Sensors provide highly detailed glucose information, finger-prick testing may still be useful when symptoms do not match readings or when glucose levels are changing rapidly.
Why does my CGM reading differ from my finger-prick result?
CGM systems measure glucose in interstitial fluid rather than directly in blood. Because of this, a small delay between readings can occur, particularly during periods of rapid glucose change.
Should I keep Test Strips if I use a CGM?
Yes. Keeping compatible Test Strips available provides a reliable backup whenever confirmation testing is needed.
Can CGM completely replace finger-prick testing?
For many routine situations, CGM significantly reduces the need for finger-prick testing. However, most healthcare professionals still recommend maintaining access to a blood glucose meter and Test Strips for specific circumstances.
