My freshman dormitory was from a wealthy suburb of Northern California, a Paris Hilton lookalike, and very familiar with the fish oil boom of the early 2000s. She took one amber egg-shaped tablet each day to strengthen her French manicure and color-treated hair. As far as I can remember, this was my first introduction to the concept of beauty supplements. Fish oil has since fallen out of favor, paving the way for biotin to take over its place as today’s notable beauty buzzword, but I was just as skeptical about his former back in 2008. , also skeptical about the latter. As my colored hair began to thin in my 30s, I found myself walking through the grocery aisles looking for the best biotin supplement against my judgment.
So I decided to find out if biotin really works for strengthening hair and nails. And what about proven brands that really live up to the hype?

Does Biotin Really Improve Hair and Nails?
Biotin is a B vitamin that most people can get from a balanced diet, especially foods such as fish, eggs, sweet potatoes, and almonds. If you don’t have enough biotin, can lead to Brittle nails and hair loss.
“a some little research We’ve shown how biotin supplementation can help strengthen already brittle nails,” Poon said. “Unfortunately, there is no evidence that biotin supplementation helps grow or strengthen already healthy hair and nails.”
Is it okay to take biotin every day?
While this question received an overwhelming “yes” from our experts, both experts agree that a balanced diet should contain sufficient amounts of biotin for adults. I pointed out that there is.
“Biotin is safe to take, even at high doses,” Horstmann says. “Having said that, overdosing can cause side effects such as stomachaches and sleep disturbances, but these are very rare.”
How much biotin do you really need each day?
The recommended daily intake of biotin for all adults is 30 micrograms.
“To find out how much food you need to eat to reach your daily goal, one egg contains 10 micrograms of biotin, and a quarter cup of sunflower seeds contains 2.6 micrograms. It contains micrograms of biotin, and half a sweet potato contains 2.4 micrograms of biotin, micrograms of biotin,” Poon explains. “It’s unlikely that you need to take a biotin supplement, but always check with your healthcare provider if you’re unsure.”
