What is BLOCK-XT?

BLOCK-XT is a stimulant-free, all-natural carbohydrate blocker designed to help you effectively reduce calorie intake from carbs, stay in ketosis (a bonus for keto-ers!), and support weight loss by decreasing your cravings for sweets. 

BLOCK-XT contains scientifically-backed ingredients, including patented Phase 2® white kidney bean extract and Gymnema sylvestre extract, which are shown in clinical trials to block the absorption of carbohydrates and enhance insulin sensitivity.

    Kidney Bean Extract
  • Gymnema Sylvestre 
  • Bioperine

Per serving - 500 mg

White kidney bean (Phaseolus vulgaris) extract is one of the most potent natural carb blockers known to man, with an abundance of clinical research demonstrating it's efficacy for reducing the absorption of calories from complex carbohydrates.

In fact, a recent clinical trial showed that subjects supplementing with white kidney bean extract twice a day lost 7 lbs more than those in the placebo group in just four weeks (despite eating equal amounts of carbohydrates). 

It is now well-documented that certain glycoproteins in white kidney have inhibitory actions on the enzyme known as alpha-amylase, which is responsible for breaking down complex carbohydrates into simple sugar molecules. By doing this, white kidney protein effectively blocks the absorption/digestion of carbohydrates, thereby reducing calorie intake. 

It's key to note that generic white kidney bean extracts have been shown to be ineffective for blocking carbohydrate intake, mainly because they often lack a nominal amount of active constituents to produce beneficial results. 

This is why BLOCK-XT includes patented Phase 2® White Kidney Bean Extract, which is standardized and purity tested to ensure efficacy.

Gymnema sylvestre is a woody shrub indigenous to tropical regions of India, Australia, and Africa. This plant has been used in Ayurvedic medicine for thousands of years as a remedy for diabetes and chronic inflammation. 

As research has grown, findings show that Gymnema sylvestre can not only inhibit the absorption of carbs and sugar, but reduce cravings for sweets and enhance insulin sensitivity. Some clinicians have even gone to the length of calling Gymnema sylvestre “nature’s anti-diabetic drug”. 

The major active constituent on Gymnema sylvestre responsible for these effects is gymnemic acid, which is shown to block taste bud receptors that sense sweetness, reduce intestinal absorption of glucose, and promote insulin sensitivity (meaning your body clears blood glucose more efficiently).

BLOCK-XT is formulated with a high-potency extract of Gymnema sylvestre to ensure you get an evidence-based dose of gymnemic acids with each serving.

Bioperine® is a patented form of black pepper fruit extract (Piper nigrum L.), an innovative ingredient that helps your body absorb and utilize the gymnema and Phase 2® in BLOCK-XT. 

A unique compound in black pepper fruit, known as piperine, helps enhance your body’s digestive capacity, stimulate digestive enzymes, and promote intestinal absorption of nutrients and phytochemicals.

This is imperative for increasing the bioavailability and synergy of the ingredients in BLOCK-XT.
