Sea Moss For Weight Loss: Does It Really Help?


Sea moss, also known as Irish moss, is a type of red seaweed that grows along the Atlantic coastlines of North America and Europe. It has long been used as a natural remedy for a variety of ailments, and recently gained popularity as a weight loss supplement.

But does scientific evidence support the use of sea moss for weight loss? This article examines the facts.
