Works very well for hair and nail strength
I have seen a very positive growth in both my nail strength and hair growth. I put the required amount in my daily electrolytes water and doesn't affect the taste. I have been using Liquid Biotin & Collagen since last September. It works very well, hair strands are thicker, no hair loss. Enjoy!

Better quality, than discount brands for sure.
I have been taking a discount brand buy one bottle get one bottle of for free that I just grabbed when I was out of biotin. It was around 5 or 6 bucks for like 600 or 1,000 tablets total. Very quickly I realized that it wasn't really doing much good and made my fingernails split and splinter and a lot of hangnails and rough skin around my nails and I also gotten like a couple of cuts very easily. After a few weeks I could deduce that's the actual biotin component in these tablets these soft gels was of poor quality and had to be that. A bad isomer a bad batch just quickly made us some cheap leftovers that a cheap marketing company got from somewhere but it was actually worsening the condition of my skin and nails. I had purchased this very expensive liquid biotin a long time ago about three or four years ago a few times. I grabbed cheap softgels because this liquid by its in head ran out and I was just out shopping. Not really thinking it through. So after a few months of trying to use some of the soft gels up I returned to get this liquid drops product now I have been using this for one week and immediately my fingernails are like if they are shiny they are smooth all of this skin that was rough and jacket around my fingers to my fingernails is now smooth and pink and not white and peeling in little shop pointy skin peeling away and immediately my nails are not going to be splitting there so naturally shiny and more rubbery looking just looking at the material that my fingernails can we feel the durability of them. And just today I accidentally sliced my finger with the very very shop serrated micro serrated steak knives I bought from Amazon which I have cut myself a couple of times with but the actual cut which is the same thing I've done twice or three times is not even nearly as bad it stopped bleeding so quickly and doesn't even hurt like the other two stung for days this liquid biotin is a very very good product if you are looking for the properties that biotin is supposed to bring to the table. Immediately metabolizes into your body it gets to work and works very well and it has got to be a quality molecule that is properly rendered or created because it gives you a quality scan and quality nails. Never seen the biotin that I've taken from many many years before trying this liquid I had used other brands of soft gels and tablets never seems to do much for my hair and I can't say as to this doing much for my hair my hair is kind of thinning from my age I really think that biotin is much more generous to skin and nail health and strength and growth than it is to hair and may be just me. You can buy it to never seem to do too much for my hair. But this is definitely worth extra costs for high quality chemical make up.

So far..So good!
Seems to be working. My nails are growing & stronger and I've noticed less hair coming out in the comb. I'm on my second bottle so hopefully it'll be more improvement. It has a good flavor too!

Excellent Liquid Biotin & Collagen
I have really enjoyed using this liquid biotin and collagen by NutraHarmony daily for the past two weeks. I have tried it plain, simply taking 2 (1/2 full) droppers under the tongue. The ‘natural raspberry’ flavor is very light and not offensive. It is however, the only reason I took one star off, because I would rather that it was plain; or that they offered a plain version. I feel like most people are going to add it to something and it is best to be unflavored. Even if you’re taking it straight by mouth, being unflavored would be okay. I do not find the flavor to be strong, and I drink my teas, coffees and other beverages strong enough that it did not conflict. I did not mix it in with water. You could also mix it with smoothies, yogurt, oats…really anything as long as it does not disturb the metabolic stability by being too hot or too cold (don’t nuke it or freeze it :p) At 20,000 mcg of Biotin, 40,000 mcg of Collagen this product has optimal absorption because liquid forms of collagen dissolve so much better in liquids or break-down in your body if taken alone. I also like that it is sugar-free, gluten-free, free of soy, milk, and lactose; has no dyes, gmo’s, preservatives or artificial colors; and doesn’t contain added sugars or sweeteners. While everything in that list of ‘NO’s’ certainly doesn’t apply to me [and likely not you] the point is that surely most things that someone is allergic to or is concerned about are covered there—and that is important. If you use this once a day, this bottle should last approximately a month. That should be enough for me to see the improvement in appearance/health of the skin as the brand alleges so when I finish this bottle I can update this review. All in all, I recommend this product and think it is a good bang for the buck.

Hair, skin, & nails
I’ve been using this for several months now. I can really tell a great improvement in my hair, skin, and nails. I’m post menopausal with problems of thinning hair and brittleness of my nails. This product has helped growth of both. I would recommend it. Try it!

What is missing?
Has something been left out from the list of ingredients? Reading what is apparently contained in this Liquid Biotin & Collagen does not suggest that this is anywhere close to the neighborhood of being dangerous. However, this has given me rashes on several areas of my body and after ruling out any type of food or anything external, I decided not to take this overnight. Upon getting up the following morning, my itching had subsided substantially. The rashes had also begun to clear up, and all of this happened from a dropper full of this. I have allergies and hives l, and I initially thought that fresh cut grass and pollen were the culprits behind my breakouts and horrible discomfort. This tag team remains my enemy, but for the moment, they are sitting ringside, watching Liquid Biotin & Collagen take the belt. LB&C were caught cheating, and have now been disqualified from entering my body ever again. At least, this particular brand. Unless, of course, I find something else in their lineup without these particular ingredients. Update:20/4/2026 - I have to make sure that I acknowledge the fact that nutra-harmony reached out to me TWICE, to not only issue a refund, but to sincerely express their concerns with my discomfort. I have NEVER experienced this before with any company, so suffice it to say that I BEYOND impressed with this alone. Thank you so much, nutra-harmony. ~ No Diggity, No Doubt ~
