In This Review

Overview

Diabetes is one of the most common and dangerous conditions in the United States. It can affect every aspect of your life and negatively impact your weight, mood, energy levels and more. More than 37 million Americans have it, and another 96 million have prediabetes.

That’s where natural supplements to lower blood sugar come in, and GL Control is one of them. GL Control is a liquid glucose support supplement that uses six plant ingredients, several with published research on blood sugar markers. The brand says the formula borrows from the dietary routines of populations where diabetes is less common.

In this GL Control review, we will understand how to lower your A1C levels, reprogram your body to effectively process glucose, lower insulin resistance and help you lose weight. So is there any truth to these claims?

Quick Verdict

GL Control is a liquid blood sugar supplement with six plant ingredients: cinnamon, bitter melon, turmeric, coriander seed, Japanese knotweed and licorice root. One dropperful under the tongue, twice daily.

It doesn’t replace prescribed diabetes medication. Several ingredients lower blood glucose on their own, so if you take metformin, insulin or a sulfonylurea, speak to your prescriber first.

The ingredients have published research behind them. The finished formula has never been trialled, and no amounts are disclosed.

What is GL Control?

GL Control is a dietary supplement that was formulated to help people prevent diabetes and lower their blood sugar levels. This is a natural supplement that may be effective as a holistic alternative to common medications like Metformin. It is also claimed to be developed by a real medical professional.

One of the things that sets GL Control apart from other diabetes supplements is that it was designed to improve the effects the more you take it as opposed to other supplements and medications that may actually lose potency as your body develops a resistance to them.

GL Control comes in liquid form and this was deliberate since the liquid formulation will be able to take effect quicker than a pill or capsule. GL Control is mostly used to control blood sugar levels but it can also help you lose a moderate amount of weight when taken consistently.

How Does it Work?

There are some important claims that the manufacturers of GL Control have made about the supplement. But perhaps the most important claim is that GL Control will work by lowering your blood sugar levels. So the question becomes: how will GL Control lower your blood sugar levels?

For the answer to that we have to look at the ingredients. For example, GL Control contains bitter melon extract which has been observed to lower blood sugar levels. Studies indicate that bitter melon has insulin-like effects thanks to the compounds charantin and polypeptide-p.

These compounds help lower insulin resistance and help exorcise fat cells of harmful compounds that lower the effectiveness of insulin. This same effect takes a large toll off of your pancreas which is responsible for producing insulin. So GL Control works to reduce blood sugar levels and support overall physical health.

Ingredients

We know how GL Control works but what’s in it? Let’s take a look at the formula:

Cinnamon

Cinnamon

Cinnamon is a common spice that has been observed to have cholesterol and blood glucose-lowering effects. One clinical trial saw a significant drop in preprandial blood glucose level after cinnamon supplementation. Here’s a quote from that study:

Serum glucose levels dropped by 18–29%. The supplementation of 1 g of ground cinnamon per day was found to improve preprandial blood glucose.

Licorice Root

Licorice Root

Licorice root has been used by Eastern medicine practitioners for a long time to help lower blood sugar levels. Modern studies have revealed that it contains flavonoids that help increase insulin sensitivity. It has therefore been hailed as a natural antidiabetic nutrient.

Turmeric

Turmeric

Turmeric is a yellow spice common in Indian cuisine. It contains the active compound known as curcumin which has been observed in clinical studie to significantly decrease fasting blood glucose levels so it can help lower morning blood sugar readings for most people.

Coriander Seed Extract

Coriander Seed Extract

Coriander seed appears to increase insulin uptake in the body and may even mimic some of the effects of insulin, making it an extremely beneficial ingredient for anyone who is diabetic or at risk of becoming diabetic. The National Institutes of Health has stated thatIn conclusion, the present study demonstrated that coriander seed powder supplementation markedly decreased serum glucose, insulin, insulin resistance.

Bitter Melon Extract

Bitter Melon Extract

As we have discussed, bitter melon helps lower insulin resistance and therefore has a beneficial effect in the fight against diabetes. However, there have also been peripheral studies that strongly indicate that bitter melon also helps slow down carbohydrate absorption which also benefits blood sugar levels and may spur moderate weight loss.

How to Use

  • Dose: One dropperful.
  • Frequency: Twice daily, morning and evening.
  • Method: Hold it under your tongue for about 30 seconds, then swallow. This is the sublingual step, and it’s the reason the product comes as a liquid.
  • Alternative: If you’d rather not, you can mix it into a small glass of water or juice.
  • Consistency: Take it at the same times each day. This formula depends on regular use rather than occasional doses.

Benefits

  • Increased Insulin Sensitivity – GL Control may help increase insulin sensitivity which will make the insulin that your pancreas creates more effective and ease the burden of producing a high amount of insulin.
  • Diabetes Prevention – For individuals who are not yet diabetic but at risk for developing the condition, GL Control could help lower your overall risk by reducing carbohydrate absorption and lowering insulin resistance.
  • More Energy – One of the most pernicious effects of diabetes is that it drains you of your physical energy. GL Control may help boost your energy levels by maintaining your blood glucose levels in the healthy range.
  • Weight Loss – Again, bitter melon can help slow the absorption of carbohydrates which may make it easier for users to manage their weight. This may result in moderate weight loss.

Side Effects

There have not been any reports of side effects from the many confirmed GL Control customers who have left a review for the product. This is a good sign that the formula is safe and won’t cause adverse effects. Furthermore, the ingredients in the GL Control formula are all-natural and have not been observed to cause serious side effects in the scientific research programs that have evaluated them.

How Effective Is GL Control?

Does GL Control work? Yes, for slow, steady support next to a healthy diet and regular movement.

The ingredients are the reason. Cinnamon, bitter melon, coriander seed and turmeric have all been studied for blood sugar. What those studies show is a small but real shift in glucose levels. That is what a supplement like this is for.

Reviews on the official site say much the same. Users report steadier energy through the afternoon and fewer crashes after meals. One, Ron L., says his morning numbers dropped in the first two weeks. These come from the brand’s own page, so take them as a guide rather than proof.

The full formula has never been tested in a study, and the amounts are not listed. So the ingredients are backed by research, but the product itself is not.

Give it a few weeks and keep checking your levels as you normally would

Safety

GL Control is made in an FDA-registered facility and the company that makes it follows Good Manufacturing Practices guidelines to ensure the safety of the product. Furthermore, all of the ingredients are natural and processed in the United States. If you are allergic to any of the ingredients or have specific safety concerns, we advise you to talk to your trusted healthcare practitioner.

I’ve been diabetic for 12 years. I’ve tried everything. This is the first thing that actually worked. I’ve been using it less than a week and I already feel like a different person. The brain fog is gone. I’m not dragging myself through the day anymore. – Kim

    Simple blood sugar support!
    I wanted a straightforward daily pill to help manage my blood sugar without any complicated steps. I bought GL Control after reading a review online. I take it with water before breakfast, and it works great. My doctor was super impressed with my recent checkup results, and I feel so much lighter and healthier.

GL-control Review Ques and Ans

  • Q : I f I take the GL-control in the AM, do I still need to take my nighttime insulin shot?...thank you...

    A: "You can take GL Control as part of your routine, but it should not replace your prescribed nighttime insulin. Continue taking your insulin as directed unless your healthcare provider tells you to make a change. Since you are using insulin, check with your doctor before adding GL Control to make sure it fits safely with your current plan. "

  • Q : Can I take GL Control with metformin?

    A: Ask your prescriber first. Several ingredients lower blood glucose on their own, so the effects can stack. It's usually manageable, but your doctor should know so they can monitor your levels.

  • Q : Can GL Control replace my diabetes medication?

    A: No. Nothing in this formula does what prescribed medication does. Never stop or reduce a prescription without your doctor's involvement.

  • Q : Can I take it with blood pressure medication?

    A: Check first. The licorice in this formula can affect blood pressure and potassium levels in some people, particularly alongside diuretics.

  • Q : Is GL Control FDA approved?

    A: No. No dietary supplement is. The facility is FDA-registered, which is a different thing.
