Spirulina is a form of algae, found mainly in South America and Africa, that can be used as a dietary supplement. It contains various vitamins and minerals, including vitamin K, beta-carotene and iron. Spirulina is also a source of essential amino acids.

Weight loss aid

Spirulina can be used to help those who want to lose weight. It provides large amounts of nutrients, which can help to prevent the overeating and binge eating that can be caused by nutritional deficits. When the nutritional needs of the body are met, the metabolism becomes more efficient, which helps to make weight loss easier.

Immune booster

It is thought that spirulina may help to improve the function of the immune system. Consumption of spirulina can also produce more anti-inflammatory chemicals, which may help to reduce the incidence of allergic reactions.

Due to the numerous vitamins and minerals contained in spirulina, it can be very beneficial for overall health.

Cancer prevention

The nutrients found in spirulina, such as beta-carotene, iron and manganese, all help to fight the free radicals which may cause cancer. The combination of the antioxidant qualities of spirulina, along with the effect of spirulina on the immune system, could make this a very beneficial food for cancer prevention.

Prevention of cardiovascular diseases

The beta-carotene contained in spirulina can help to lower the levels of bad cholesterol (LDL) in the body. High levels of LDL can cause hardening of the arteries and lead to strokes. Spirulina also helps to lower blood pressure.

Anti-ageing

Spirulina can be beneficial as an anti-ageing food due to being an excellent source of nutrients, such as beta-carotene. Beta-carotene is converted to vitamin A, which is an antioxidant that provides protection against free radicals. Free radicals can affect cell renewal and cause wrinkles, a decrease in skin elasticity and reduced suppleness of the skin.

Healthy digestion

Spirulina can boost the beneficial bacteria in the digestive tract, which is helpful for promoting healthy digestion and bowel function. Spirulina can also be used to detoxify the body, as it cleanses the toxins from the body while providing nutrients. It can also be used to relieve digestive problems, such as constipation.

Bone health

Spirulina is a good source of vitamin K, which can benefit bone health. Those suffering from osteoporosis may benefit from spirulina, as the vitamin K can help to form strong bones.
