3 Documented Benefits
3/5 Evidence Score

InSea2® is a blend of polyphenols from two brown seaweeds, Ascophyllum nodosum and Fucus vesiculosus, from InnoVactiv. The seaweed polyphenols slow the digestive enzymes that break down starch and sugar, helping blunt the rise in blood sugar after carbohydrate-rich meals.

Studied Dose About 500 mg taken before a carbohydrate-containing meal.
Active Compound A standardized blend of brown seaweed (Ascophyllum nodosum and Fucus vesiculosus) polyphenols that inhibit carbohydrate-digesting enzymes.

Benefits

Gentler post-meal glucose

By slowing the digestion of starch and sugar, the seaweed polyphenols help reduce the spike in blood sugar that follows carbohydrate-rich meals.

Supported by Trial 1

Insulin response support

Lower post-meal glucose is accompanied by a more moderate insulin response, supporting metabolic balance.

Supported by Trial 1

Carbohydrate management

As a meal-time carb manager, it is used in glycemic-support and weight-management formulas.

Mechanism of action

1

Enzyme inhibition

The polyphenols inhibit alpha-amylase and alpha-glucosidase, the enzymes that break carbohydrates into absorbable sugars, slowing glucose entry into the blood.

2

Antioxidant polyphenols

Brown seaweed polyphenols also provide antioxidant activity that supports vascular and metabolic health.

Adults.

The seaweed polyphenol combination supported improvements in glycemic and metabolic measures, consistent with carbohydrate-enzyme inhibition.

Side effects and drug interactions

Common Potential side effects

GENERALLY WELL-TOLERATED — mild digestive symptoms are the most common.
