What Is Red Marine Algae and What Are Its Health Benefits

A strong, resilient immune system is the foundation of good health. If you’re struggling with any type of chronic virus, skin troubles, and a generally weak immune system, red marine algae is worth learning more about. 

What is Red Marine Algae?

Red Marine Algae, commonly known as a sea vegetable, is a type of algae that grows abundantly in the ocean. It has been used by Chinese and Japanese cultures for centuries for its nutritional benefits.

There are more than 4,000 species of red algae, and two of the most beneficial and potent strains are Gigartina and Dumontiacea. It's suggested to take both strains together.

Gigartina & Dumontiacea Strains of Red Marine Algae

Gigartina papillata is an active strain of red marine algae found particularly beneficial for the skin and immune system. It’s very rich is sulfated polysaccharides, which are unique protein-bound carbohydrates, found to support the body’s immune response to bacteria, viruses, fungi and toxins.

Gigartina red marine algae also contains carrageenan, a sulphuric acid extracted from sea vegetables. This carrageenan component seems to help direct the beneficial immune-enhancing effects of Gigartina toward the skin. People use gigartina for chronic viruses like oral herpes, genital herpes, shingles, HIV, influenza and mononucleosis. 

Dumontiacea is a specific type shown to have antiviral properties. People specifically use this strain for herpes simplex virus I and II because it may suppress the herpes virus in the initial stages of flare-up, and increase the length of time between outbreaks. 

Health Benefits of Red Marine Algae

Red marine algae supports a healthy immune system and steady immune system response because of its sulfated polysaccharide content.

Red marine algae is used to support healthy skin (psoriasis, eczema, herpes), hair, nails, and immunity. It may support quick recovery and a decrease in severity of skin troubles and lesions. Customers have reported that Red Marine Algae Plus has changed their lives, and have permanently switched to this product over L-lysine and over-the-counter topical creams.
