Plexus BLOCK


Plexus BLOCK contains natural ingredients, clinically-tested to work immediately to block the absorption of up to 48% of carbs and sugars from your meal— without blocking the absorption of any beneficial nutrients.*

When you eat, the body does what it’s naturally wired to do — converts carbs and sugar into glucose. But when too much glucose is converted at once, the excess can be stored as fat. Excess glucose means excess fat and excess fat can lead to excess weight.

Take control of what you eat, with BLOCK.
