Chlorella and chlorella dietary supplements contain a variety of essential vitamins important for overall health. A link between chlorella and hair loss exists in that the high beta-carotene levels, converted to vitamin A, are believed to promote healthy hair growth. Whether chlorella actually helps new hair grow or can stop hair loss is not known.
Chlorella, also known as sun chlorella and green algae, is freshwater alga often used in supplements. Chlorella plays an important role in photosynthesis. Its large amounts of chlorophyll, a chemical that plants require to get their green color, helps convert the light plants absorb into energy. Even though the single-celled alga is commonly used in Japan to treat a number of conditions, according to the American Cancer Society, no scientific evidence exists that have proven its effectiveness.
Chlorella is rich in a number of ingredients, including vitamin C and a high concentration of B-complex vitamins. The carotenoid beta-carotene is also part of the alga's primary make-up. Vitamin C and beta carotene act as antioxidants that help block free radicals in the body. For this reason, chlorella is a popular dietary supplement to relieve a variety of symptoms. It's believed that chlorella boosts albumin levels in the body, a protein that presumably protects against diseases including cancer, arthritis, cirrhosis and AIDS. Yet there is no available scientific evidence to support such claims.
Because of the high levels of beta-carotene in chlorella, the green algae is thought to be a good supplement for promoting hair growth. Beta-carotene provides approximately 50 percent of the vitamin A that your body requires, according to MedlinePlus. Vitamin A is a popular ingredient in hair growth products.
Chlorella dietary supplements are available in tablet form, as well as liquid extracts and as powder. The recommended daily dosage is 2g to 3g per day, and is believed to be most effective when mixing the powder form with foods made from flour. A number of authoritative bodies, such as the American Heart Association and the World Cancer Research Institute, recommend getting beta-carotene from foods rather than supplements because the effectiveness of beta-carotene in supplements is not yet fully known. If you take chlorella for its beta-carotene, taking a supplement may not deliver all of its benefits.
Studies on chlorella's side effects on humans have not been conducted. However, chlorella dietary supplements are believed to be generally safe. Be aware of many falsified or unverified claims about chlorella. The Food and Drug Administration has issued warnings to distributors of the supplement for making misleading statements about chlorella's benefits. No hard scientific evidence exists that taking chlorella will stop hair loss or promote new hair growth.
