Trace Minerals Ionic Biotin + Collagen Supplement, 75,000mcg, 2 oz, Vitamin B7 biotin formula, Supports hair, skin, and nails, ConcenTrace ionic trace minerals, 2 mL daily serving, Sugar free

I have trust in Trace Minerals brand - have been using their other products for years. It is very easy to use their liquid products.

Been using this stuff for awhile. It's clean and works great.

Been taking the Trace Biotin + Collagen consistently and my skin is noticeably clearer and my hair feels thicker and stronger. Great quality for the price. Simple, effective, no complaints.

Fantastic Stuff!!!

So far I have been using the product for just over a week. The flavor is delicious- I add it to my 40oz bottle of water with minerals. I havent been using it long enough to notice any changes but I will continue and hope to eventually see a change in my hair, skin, and nails!

I've taken this product for at least three or more years. I truly noticed the difference when I had finished a bottle and didn't replace it for a few weeks.

tastes great, easy to take no mixing. my nails have improved so much since starting this! Love the whole trace minerals line!

The main problem with this item is the taste. It reminds me of cough syrup and is kind of unpleasant. I've just started using it so it's too soon to know whether or not it works well in terms of the benefits from biotin/collagen. Hopefully there will be benefits that make it worth the unpleasant taste.

this has a pleasant taste. I don't notice an after taste. can't tell if it's working or not yet but overall it's okay.
