It is possible to get too much of a good thing, but will biotin and hair loss go hand-in-hand if you take too much? Vitamins and supplements that provide your body with needed minerals are wonderful — but like everything else, you can get too much of them in your system. Will excess biotin cause your female hair thinning to get worse instead of better?
When more is too much
Female hair thinning can be caused by vitamin deficiencies. Like every other part of your body, your scalp and hair follicles need a certain amount of minerals to stay healthy. But if you over-do it with the vitamins, you’re only going to be doing yourself more harm.
Excessive amounts of Vitamin C, for example, will create symptoms like diarrhea, stomach cramps and nausea. Overdose on Vitamin A, and you might suffer from dizziness and blurred vision. But it’s also very rare to suffer from too many vitamins from food alone; it’s pretty impossible to eat that much. If you’re taking vitamins or enriched supplements and eating very vitamin-rich meals to boot, however, you could be receiving a little much of a good thing. Pay attention to what you’re eating, and the vitamins you’re taking, to get an idea of how many nutrients you’re actually receiving. If you think you might be taking too many vitamins, consult with your physician about what you’re ingesting.
Biotin and hair loss
Biotin, a B vitamin, is often taken by women who want to stave off or manage female hair thinning problems. Female hair thinning can be caused by vitamin deficiencies, but it’s also caused by a variety of other issues. High fever, illness, certain medications, genetics, scalp trauma — all of it may lead to female thinning hair. Women can use Biotin to encourage healthy hair growth and keep follicles strong. But can they use it too much?
For many women, the daily recommended dose of biotin (around 35mg) can be reached through normal food consumption. It’s found in egg yolks, liver, salmon and avocado. It’s one of the most important hair-growth vitamins, and if you don’t get enough biotin your hair can become fragile and prone to breakage. Biotin keeps not just hair healthy, but skin and nails as well.
No scientific reports prove biotin toxicity. The National Institute of Health does not recommend taking higher doses than the recommended amount, but doses as high as 200mg have been studied and seem to produce no recognizable negative side effects. Because biotin is water-soluble, taking excessive amounts probably will not cause you harm. But a lack of data doesn’t mean you should consume copious amounts of biotin in your daily diet. Take only the recommended amount to keep hair healthy, because there’s no evidence that shows taking more is at all beneficial to your body, either.
