Phase 2 Carb Blocker is for weight management and is one of the fat loss supplements formulated by WhatSupp Nutrition. It contains the clinically studied ingredient, white kidney bean extract, and it claims to help people lose weight by blocking the body from digesting a portion of ingested carbs.
Each serving size (3 veggie capsules) of Phase 2 Carb Blocker contains 1.5 grams (1,500 mg) of Phase 2 Starch Neutralizer (White Kidney Bean Extract). The suggested use is to take one serving before any meal containing complex carbohydrates or starches, or as directed by a health care professional.
Phase 2 Carb Blocker’s single active ingredient is white kidney bean extract, also known as phaseolus vulgaris. The common belief is that this herb is a carb blocker, a compound that affects the digestive process and results in the absorption of less dietary carbohydrate.
More specifically, white kidney bean extract is thought to function as a type of alpha-amylase inhibitor. Amylase is a digestive enzyme that is in charge of digesting starch. By blocking this enzyme, it prevents it from digesting starchy carbohydrates, which means that these carbs are not broken down into glucose and are eliminated as waste by the body.
That being said, even if white kidney bean does have this effect, carb blockers only block complex carbohydrates. These include grains, vegetable and legumes. Carb blockers have zero effect on simple sugars because they do not need amylase to be digested. This means that they are ineffective on sugars found in fruit, milk, natural sweeteners, cakes, candy, etc.
While Phase 2 Blocker is correct in that it does contain a clinically studied ingredient, this ingredient has never been proven to lead to positive weight changes. More research needs to be conducted to know just how safe this herb is and how – or even if – it can benefit weight loss.
As for side effects, for the most part, white kidney bean is typically safe when taken as an oral supplement for the short term. The most common side effects are stomach upset, diarrhea, nausea and vomiting. That being said, it may lower blood sugar. Therefore, if you are pre-diabetic or a diabetic, this may not be the right product for you to take. This is also true if you are pregnant or nursing.
It is in your best interest to play it safe and talk to your healthcare provider before taking Phase 2 Carb Blocker.
