How it Works

At the heart of all Sea Green Health products is SeaGreen-H1, our proprietary blend of Tetraselmis chuii and Dunaliella salina, two species of marine microalgae of high nutritional value.

Tetraselmis chuii is harvested organically for it’s several health benefits, and includes a wide spectrum of vitamins and trace elements. The algae is also rich in SOD (superoxide dismutase), one of nature’s strongest antioxidants, and other antioxidant enzymes such as Catalase. These help support the immune system and also support normal functioning of energy metabolism in the body. SOD is present in every cell in the body, protects all cells from harmful free radicals and also acts as a powerful anti-inflammatory.

Dunaliella salina is another marine microalgae with proven health benefits. It is a rich source of beta-carotene, alpha-carotene, zeaxanthin, cryptoxanthin, lutein and lycopene. Beta carotene is converted into essential vitamin A and is synthesised only up to the level needed, therefore always guaranteeing the required antioxidant level. Beta carotene helps to support a healthy immune system and helps to maintain healthy skin and eyes. Dunaliella extracts are also potent free radical scavengers. 

Beta-glucan (in the form of Bakers yeast extract) has proven positive effects on the immune system. Beta-glucan is a natural polysaccharide which helps to modulate the immune system to make it as efficient as possible.

Ginger extract is added, as one of the key ingredients in Ginger, Gingerol, has been shown to support the immune system.

Vitamin C’s importance to the immune system is long established. It supports the function of various immune cells and enhances their ability to protect against infection.

Bioflavonoids are strong antioxidants that are mainly found in fruit but which are also found in vegetables. As well as fighting oxidative stress in the body, flavonoids have been shown to work synergistically with other antioxidants such as vitamin C.

Vitamin A, as well being an important micronutrient for maintaining vision, promoting growth and development, is known as an anti-inflammation vitamin because of it’s critical role in enhancing immune function.

Zinc’s role in supporting the immune system is well understood. It is crucial for normal development and functioning of cells in the immune system.

Vitamin D3 (vegan) is added and has long been known to play a role in supporting a healthy immune system and supporting calcium absorption. We all understand the need to have a good source of vitamin D in our diet, and we include a very high quality VEGAN source material. It is not always possible to get enough sunlight to produce enough ourselves.

Vitamin E is added in one of it’s most bioavailable forms. It is a potent antioxidant making it effective at combatting the effects of free radicals and thus supporting the immune system.

Iron deficiency can result in a weakening of the immune system, and so is an important addition to the formula, added in a bioavailable form.

Selenium plays an important role in supporting the immune system. It is a powerful antioxidant which helps to lower oxidative stress in the body and reduces inflammation.
