Unicellular blue algae, going by the name Spirulina, are recognized as one of the most potential sources of protein and other vital nutrients among plants. 

​Spirulina stimulates, strengthens and enhances the human immune system and is particularly useful for the maintaining of a healthy and balanced diet. 

There are data that show that people eating apirulina rarely have adverse conditions such as hypoglycemia, bad memory, chronic fatigue, high cholesterol levels, high blood pressure, poor immunity, skin problems, allergies, asthma, and depression.

​Spirulina, in the form of dried algae, has been known from the time of the ancient Maya and Aztecs, who used it to strengthen and rejuvenate their bodies. Nowadays, spirulina is used as a vegan source of protein and vitamin B12.

Scientists claim that Spirulina is one of the natural sources that is richest in antioxidants (high content of phenolic acids, tocopherols), besides it contains 25 times more provitamin A than raw carrots and 50 times more iron than raw organic spinach. ​

Fucoxanthin is a substance with serious health potential, but also with a lot of unknown sides. It is one of the most common marine carotenoids, as astaxanthin is more widespread.

​It is an orange-brown pigment that occurs mainly in brown algae as Wakame (Undaria pinnatifida) and Hijiki (Hijikia fusiformis) but can be found in smaller quantities in other marine sources.

Although it is from the group of carotenoids like astaxanthin, it is not essential; it does not get converted into vitamin A in the body and does not affect the levels of the vitamin in the blood.

​​Fucoxanthin is a carotenoid found in brown seaweed. It is being investigated for its fat burning abilities. It claimed that reduces fat mass. There was a study has involved 151 overweight women before menopause.

The comparison was between women with normal levels of liver fat and others, diagnosed with nonalcoholic fatty liver. The tested product contained 300 mg of brown seaweed extract, with a total concentration of 2.4 mg of Fucoxanthin.
