I’ve been using these NutraHarmony Biotin, Collagen & Keratin capsules for a while and I’m really happy with them. I like that they are capsules instead of gummies, since they don’t have added sugar. The formula is very complete — it includes biotin, collagen, keratin, hyaluronic acid, and B-complex vitamins. After consistent use, I’ve noticed my nails feel stronger and less brittle, and my hair looks healthier overall. They are easy to swallow, made in the USA, and the bottle lasts a full month (2 capsules per day). Results are not instant, but with consistency you can definitely notice improvements. Overall, a solid supplement if you’re looking to support hair growth, skin hydration, and nail strength. Read more

Great product!!! It took several months (around 6 months or so for me) for it to really start working for me. When it kicked in, my hair started growing a lot faster and thicker, and my nails got even stronger than they were. The key is to take consistently, every single day - do not miss. Allow time for this to kick in, at least 3-4 or months or longer. Read more

It seems to be okay and strengthen my nails and such but it does contain a large amount of biotin per serving and my stomach does get a little upset but otherwise it does seem to have an improvement on my nail strength. As for my hair I think it's okay. A little less biotin per serving and this would be great. Read more

I had a neck brace with a lot of velcro on it, I had to keep my hair in a ponytail on the top of my head and ended up with a bald spot right front and center of my hair and being a woman with a large bald beacon where everyone can see it made me feel bad. I tried different types of hair supplements for about 6 months per and got nothing from them. I finally found this and about the 4th month I noticed hair poking out of my head in the bald area, and I ran my hand over my entire head and felt prickly little new hairs growing in. The bald spot is gone and my hair grows really fast although some parts are growing faster than others, but you can't really expect a pill to know where to add growth, I just trim it a bit if it looks like a spot needs it, but it really isn't that noticeable to anyone. It doesn't bother my stomach, easy to swallow, I haven't noticed a taste although I take a few vitamins at the same time, seems to be strong enough since it fixed my hair and the money is so worth it.

Mi mamá ya va por el segundo frasco y está viendo resultados: el cabello más fuerte, le ha crecido más y, sobre todo, ya no se le cae tanto. Ahora se le ve abundante; antes tenía poco, y gracias al producto le está ayudando mucho.

Now it looks full; before, she had very little, and thanks to the product, it's helping her a lot. Read more

At 51 and still in perimenopause, my hair has taken a good beating over the past year. It has gotten really dry and began thinning out. I've always been blessed with thick, shiny hair despite beating it up wearing it in a ponytail while running miles and miles. I started using a collagen tablet last August. While it's definitely helped with joints, it wasn't until I added this Biotin multiple mineral supplement in December 2025 that my hair finally started growing again. I'm still taking the collagen supplement even though this one has some. I think the two combined has been the magic potion for my hair growth and cervical disc healing. my new hair growth is about three inches since Dec 2025. For reference, the collagen I use is also sold on Amazon. Vital Vitamins Multi Collagen Capsules - Type I, II, III, V, X - Grass-Fed, Collagen Peptides Supplements Capsules are typical size so be prepared if you're not good at swallowing capsules. Read more

This supplement is easy to take and includes a nice combination of ingredients like biotin, collagen, and hyaluronic acid. The capsules are a good size, don’t have a strong aftertaste, and the bottle is clearly labeled. It fits well into a daily routine, and the packaging arrived sealed and fresh. Overall, very happy with the quality. Read more
