How to Choose the Best Carbohydrate Blocker Supplement?

The following points are crucial while buying carbohydrate blocker supplements.

Side Effects

Carbohydrate blocker supplements’ most prominent side effects are bloating, diarrhea, low blood sugar, fatigue, stomach cramps, acidity, etc. Although the side effects are relatively minor, they can get severe without proper monitoring. Proper research on the potential side effects of the supplement is, thus, necessary before purchasing it.


Knowing the ingredients used in carbohydrate blocker supplements is essential before purchasing them. Because the supplements can both have natural ad chemical ingredients. It is always advisable to have natural ingredients like a white kidney bean, dandelion root, etc., in the supplement. Consuming supplements with chemical ingredients for a long time can have long-term health issues.

Potential Drug Interactions

Drug interactions are a common occurrence for many carbohydrate blocker supplements. This happens when the supplement’s components interact with one or more medicines the user consumes and causes a reaction. This mostly happens with supplements that have chemical content. A warning on the supplement’s container will mention the risk of people consuming other drugs. It is essential to look for this warning and crosscheck the possible drug interactions, especially if you have a medical condition and are under medication.

Type of Carbohydrate Blocker

Carbohydrate blocker supplements can be of two types: White kidney bean extract inhibitors and Alpha-glucosidase inhibitors (AGI). The kidney bean ones are the most popular, and you can quickly get a hold of them in pharmacies and online markets. AGIs are only available with a doctor’s prescription. They are highly useful in curbing the high glucose level in the blood too.

Claims on Blood Sugar Control

Most of the carbohydrate blocker supplements available online claims blood sugar control. But based on scientific studies, white kidney bean extract supplements are not very good at controlling blood sugar; thus, such claims can be misleading. AGI supplements that contain Salacia are the only ones that have proven effective in preventing high blood sugar levels. So, while purchasing supplements with blood sugar control claims, crosschecking is vital.


Carbohydrate blocker supplements are extremely useful in weight management. They inhibit the ingestion and absorption of carbohydrates to the body and eliminate both carbs and fat from the body. This leads the body to lose weight considerably over time. Despite the availability of numerous products, the Pharmaganics Dr. Stephanie’s Carbohydrate Blocker Supplement comes at the top of the list for its convenient capsule form, unflavored flavor profile, fast results, and many more.
