At Plenthera, you'll find biotin in all common dosages — from conservative 1,000 µg to beauty formulas with 10,000 µg.

Raw egg white contains avidin, a protein that binds biotin and blocks its absorption. Today, this is an interesting historical curiosity; in modern diets, hardly anyone consumes enough raw egg white to cause a deficiency.\u003c\/p\u003e\n\u003c!--en--\u003e\n\u003cp\u003eFor most people, a varied diet provides more than enough biotin. Egg yolk, liver, salmon, sunflower seeds, walnuts, mushrooms, and avocado are all good sources. The gut flora also produces biotin — a second natural route. True biotin deficiency is rare and usually related to specific circumstances: prolonged raw egg white consumption, certain anti-epileptic drugs, pregnancy (increased need), or genetic disorders.\u003c\/p\u003e\n\u003c!--en--\u003e\n\u003cp\u003eNevertheless, biotin is one of the best-selling beauty supplements worldwide. Marketing promises stronger hair, longer nails, better skin. Scientifically: in proven deficiency, supplementation demonstrably works. In healthy people with normal status, the effect of extra biotin on hair\/nail quality is much more limited than much marketing suggests.
