Red marine algae

You may be familiar with many of the herbs and compounds found in your favorite beauty supplements, but you may not know that algae — specifically red marine algae — can do wonders for your skin. It's one of the most lesser-known, underused superfoods.

That’s why this surprising ingredient is used in skin care products and supplements alike. In fact, some research shows that red marine algae can help promote skin hydration and overall skin health.

What Is Red Marine Algae?

Red marine algae is a collective term used to describe various species of marine algae that belong to the Rhodophyta division. These algae are characterized by their reddish or reddish-purple coloration, which is attributed to the presence of pigments like chlorophyll a, chlorophyll d and phycoerythrins. Unlike plants on land, red marine algae lack vascular tissues.

Key characteristics of red marine algae include their adaptability to various environmental conditions, with many species thriving in shallow waters. They are commonly found in coastal areas around the world, particularly in rocky intertidal zones and coral reefs.

Red marine algae play a crucial role in marine ecosystems. They contribute to the production of oxygen, provide habitat and food for various marine organisms, and support overall biodiversity in coastal regions.

Beyond their ecological significance, certain species of red marine algae have been of interest for their potential health benefits. Some varieties are believed to possess properties that support a healthy immune response and are used in traditional health practices for various purposes. Extracts from red marine algae are also used in dietary supplements and skin care products due to their beneficial mineral content and other bioactive compounds.


Here are some of the potential benefits associated with red marine algae:

1. Support for Microbial Balance

Some studies suggest that certain compounds found in red marine algae may help promote overall microbial balance, making red marine algae a subject of interest health-wise.

2. Support a Healthy Immune System Response

Red marine algae are thought to support a healthy immune system response. The bioactive compounds in these algae may contribute to a proper, normal and healthy immune system response, helping promote the body’s built-in first line of defense: a healthy immune system.

3. Brimming with Essential Minerals

Red marine algae are a good source of essential minerals, including calcium, magnesium, iron and trace elements. These minerals play crucial roles in various supporting healthy physiological functions.

4. Support a Healthy Inflammation Response

Some studies suggest that red marine algae can support healthy inflammation levels. Of course, inflammation is a normal response, but it’s important to keep "inflammaging" in balance for overall health.  

5. Joint Health Support

Due to their potential healthy inflammation response supporting properties and mineral content, red marine algae are sometimes included in supplements aimed at supporting joint health.

6. Skin Care

Red marine algae extracts are commonly used in skin care products, including daily skin care routines, due to their potential benefits for the skin. They may help in hydrating the skin and providing antioxidant effects, contributing to overall skin health.

How to Use

Red marine algae can be used in various ways, depending on your preferences and the specific form in which you obtain it. (As always, you should consult your healthcare professional prior to beginning any new dietary or lifestyle regimen, including dietary supplementation.)

Here are some common ways to use red marine algae:
