Nature's Bounty is one of the most popular supplement brands in the US, and their Hair Growth capsules is one of the brand's most popular products. The brand claims this supplement is clinically shown to help grow thicker, fuller hair in three months.

But is this supplement actually shown in clinical studies to be effective? Does it contain research-backed ingredients for hair growth? Does it have any unhealthy additive ingredients? And how do real users rate and describe its effects?

In this article we'll answer all of these questions and more, as we analyze the ingredients in Nature's Bounty Hair Growth capsules to give our take on whether or not they're likely to be effective.

We'll also share our concerns about the brand's claims of clinical efficacy, and feature unsponsored customer reviews.

Ingredient Analysis

Nature's Bounty Hair Growth capsules active ingredients

The active ingredients in Nature's Bounty Hair Growth are shown above.

Biotin is included in many hair growth supplements, but we can't find any clinical evidence that it's effective in individuals without a biotin deficiency.

A 2017 medical review analyzed the use of biotin for hair loss, and found that in all cases where it was effective, individuals had a biotin deficiency.

Arginine is clinically shown to protect hair from damage, as we documented in our review of hair brand Inala.

Arginine silicate inositol and magnesium biotinate were shown in a 2023 clinical trial to promote hair growth in rodents.

A 2019 clinical trial reported similarly positive results for this active ingredient combination.

We can't find any clinical studies in humans reporting that this ingredient combination causes hair growth.

The inactive ingredients in this supplement are shown below:

These inactive ingredients should be safe and non-toxic.

Overall, we consider Nature's Bounty Hair Growth capsules somewhat likely to be effective for promoting hair growth given the clinical research backing in animal studies.

Real People Try Nature's Bounty Hair Growth

Confusing Clinical Claims

As referenced in the intro to this article, the product page on Nature's Bounty's website claims that this supplement is clinically shown to work.

However, we can't find any clinical studies on this supplement published in peer-reviewed journals.

Additionally, the clinical claim on Nature's Bounty's website doesn't have a citation proving that claim. Rather, the citation links to a standard FDA disclaimer, shown below:

We dislike when brands make claims of clinical efficacy without linking to the study, or providing proof for those claims.

Real Customers Rate Nature's Bounty

Amazon is a better resource for honest customer reviews than a brand's website in our opinion.

Nature's Bounty Hair Growth supplement has been reviewed over 400 times on Amazon at the time of publishing this article, with an average customer review rating of 4.2 out of 5 stars.

A top positive review from a verified purchaser is written by a user named "S.M. Green" who gave the product a 5/5 rating, and claims it was effective for their mother:

"My mother is a senior citizen and noticed that her hair is thinning drastically. That’s actually worked very well not only did her hair thicken up and had more body and it looks so much prettier than before."

A top negative review from a verified purchaser comes from a user named "Ryan" who gave the product a 1/5 rating, and claims it was ineffective:

"It made no difference in the thinning of my hair. There is no supplement out there that can produce more hair. If the follicle is dormant it is done."

Nature's Bounty has an average review rating of 1/5 stars on the Better Business Bureau (BBB) website, but the brand responds to customer complaints attempting to resolve the issue, which is a good sign of brand quality.

Dermatologist on Best Hair Growth Supps

A dermatologist and popular YouTube creator named "Dr Dray" has a video sharing her thoughts on the best hair growth supplement:

Our Clean Hair Growth Picks

Happy Head Topical is our top hair growth solution.

This formulation uses FDA-approved hair loss ingredients like minoxidil which is clinically shown to increase hair count by 11%.

Momentous Zinc is our top value hair growth solution.

A 2022 medical review on the use of zinc in dermatology concluded that "This review has found evidence to support the use of zinc...in hair loss disorders."

MBG Omega-3 Potency+ is our top hair thickness pick.

Supplementation with omega-3 fats and antioxidants is clinically shown to improve hair density, and MBG's supplement contains both.

All of the products recommended in this section are entirely free of ingredients we consider to be unhealthy.
