The 28 Best Biotin Supplements for Hair Growth 2021

Are you dissatisfied with your hair?

Maybe it’s not long enough or strong enough.

Perhaps it’s thinning.

That’s why you’re interested in the best biotin supplements for hair growth.

The things that damage hair and cause it to fall out

There are many reasons why hair breaks, thins, falls out and looks like straw.

It might be genetic.

It could be caused by hormone fluctuations or illness.

Or the damage may result from medications, stress, color treatments, and heat styling (1).

It’s rare, though, that hair loss comes from a lack of biotin.

So why would you supplement your diet with extra biotin?

Do biotin supplements actually increase hair growth?

Does biotin promote hair growth? 

Biotin supports the production of keratin, the protein that makes up your hair and nails (2).

Two studies from the prior decade measured how much biotin impacts hair growth.

Both times, participants who took a biotin supplement for a few months had significantly more hair (3).

The supplement used during the second study had 120mcg of biotin and contained other nutrients like vitamin C, niacin, calcium, iron, and zinc.  Moreover, it had natural remedies like marine collagen, shark cartilage, and horsetail.

Are there any side effects to taking biotin?

Expert nutritionists say adults should get at least 30 mcg of biotin per day. That’s easy to do if you eat eggs, cheese, spinach, mushrooms, cauliflower, bananas, or almonds.

But you’ll notice that many biotin supplements provide 5000 mcg or more.

Fortunately, biotin is a B vitamin, and it’s water-soluble. If you take too much, your body should get rid of the excess in urine.

On the other hand, a few people will experience nausea, diarrhea, and acne (4).

It can also mess up blood sugar levels and blood test results.

If you want to take a biotin supplement, check with your doctor first. That way, you’ll be sure it won’t interact with any medications, either.
