Overview
Taking berberine supplements may be helpful for lowering your blood sugar levels and reducing your overall risk of adult-onset diabetes. However, some of these kinds of supplements can cause serious side effects for certain users, almost negating the health benefits.
Klaire Labs Berberine is a supplement that claims to be different. The makers of this supplement say that it separates itself from common berberine supplements by using a hypoallergenic form of berberine that is safer for a wider swath of users. This may make it viable for people with common food allergies.
The makers of Klaire Labs Berberine go on to say that their product will help the user successfully manage their blood glucose levels in the healthy range. So does Klaire Labs Berberine live up to all these promises? Find out in the following Klaire Labs Berberine review.
What is Klaire Labs Berberine?
Klaire Labs Berberine is a natural supplement that comes in capsule form. The capsules are meant to be convenient when compared to supplements that come in powdered drink mix form or even gummy form. Klaire Labs Berberine is also claimed to be a plant-based supplement.
The manufacturers claim that Klaire Labs Berberine will aid with glucose regulation and lipid metabolism. There have even been some claims by Klaire Labs Berberine users that the product is just as effective if not more effective than popular prescription medications for high blood sugar levels.
However, it should be noted that Klaire Labs Berberine only contains one active ingredient so the overall effects may be limited. In any case, people seem to take this supplement for the purported effects on metabolism and blood sugar support.

How Does Klaire Labs Berberine Work?
It should be noted that Klaire Labs Berberine contains only one active ingredient. So to understand how Klaire Labs Berberine is intended to work, you have to take a look at this sole active ingredient.
There have been some studies that seem to suggest that berberine, the sole active ingredient in Klaire Labs Berberine, can help lower blood sugar levels by affecting certain receptors in the body that are involved in insulin processing. In this way, Klaire Labs Berberine may work by reducing overall insulin resistance.
There are also claims that Klaire Labs Berberine will work by enhancing lipid metabolism. Berberine may also be effective for this purpose as well. However, consumers should be aware that the effect on lipid metabolism may only be moderate and that you should not stop taking any medications you may be on and replacing them with Klaire Labs Berberine. While berberine may aid lipid metabolism, its effects are considered moderate. This supports the findings in our WOWMD Berberine Essentials Review (our review of another product containing this ingredient), where we explore how berberine contributes to metabolic health and its role in lipid regulation.

In their review, they concluded that berberine seems to be effective for lowering HbA1c levels.
However, it should also be noted that while berberine is generally regarded as mildly effective for lowering blood sugar level, it is not without its risks. The National Center for Complementary and Integrative Health published a full report on berberine and pointed out some of the observed side effects.
