Potency & Hair/Skin Benefits
9.0/10With 5,000 mcg of biotin per softgel, this supplement hits the sweet spot for many users seeking hair and nail support without megadosing.
Among 99,000+ reviews, owners frequently mention thicker hair and fewer nail breakages after a month of consistent use.
The coconut oil base may support absorption, as biotin is fat-soluble.
Those with more severe hair thinning may need 10,000 mcg; the Sports Research 10,000 mcg variant is a natural step up.
For most users, 5,000 mcg daily supports visible hair thickening and stronger nails within 8–12 weeks.
Value Compared to Alternatives
9.0/10Priced competitively in the mid-range, this 5,000 mcg biotin per softgel, making it an affordable daily supplement.
The 120-count bottle lasts 4 months, stretching your dollar.
Nature’s Bounty 10,000 mcg 120ct (per softgel) offers double the biotin for less, but lacks the vegan certification.
For those prioritizing plant-based ingredients, the premium is justified.
At roughly per serving, this vegan biotin offers excellent value—but Nature’s Bounty high-potency options cost less per mcg.
What Could Be Better
8.5/10While 5,000 mcg works for most, some users report that results are slower compared to 10,000 mcg supplements.
The softgel size is slightly larger than average, which may bother those with difficulty swallowing pills.
Also, this is a single-ingredient biotin — unlike multivitamins that add keratin or collagen for synergistic benefits.
If you need maximum strength or a smaller pill size, consider alternatives.
Daily Use & Buyer Experience
9.0/10Buyers report significant improvements in hair thickness and nail strength after 2-3 weeks, with some noting a glowier complexion.
A small number mention mild digestive upset if the softgel is taken on an empty stomach; pairing it with a meal solves this.
The softgels are easy to store and have no strong aftertaste, according to most verified purchasers.
Biotin can accelerate hair growth all over, which some users find undesired.
Take with food to avoid potential digestive side effects; visible changes may take several weeks.
The Sports Research Difference
8.5/10Sports Research, founded in 1980, emphasizes purity and transparency — this biotin is non-GMO, gluten-free, soy-free, and made in a cGMP-compliant USA facility.
The Plantgel capsule avoids bovine gelatin and carrageenan, common in other softgels.
Comparing it to the brand’s 10,000 mcg version, both use the same vegan formula, so the choice boils down to potency preference.
For vegans and those seeking a clean, filler-free supplement, this is a top contender; but if you want more biotin, the 10,000 mcg version exists.
