Formulation Notes

Natural weight management

Brown seaweed contains a pigment, fucoxanthin, which gives seaweed its color as well as an amazing array of health properties. Preliminary studies suggest that fucoxanthin may increase a protein called UCP1. This may signal the body to convert the fat in adipose tissue into heat and energy.

It may also reduce metabolic inflammation generated by visceral adipose tissue.

Contains no yeast, dairy, egg, gluten, soy or wheat. Contains no sugar, salt, preservatives, or artificial color, flavor or fragrance.

Additional Information

Store in a cool, dry place.
