Dropper beats pills every time
I could never keep up with capsules. One dropper in my morning smoothie and done. Three months in and my nails have never looked better.

My hairdresser asked what changed
Been using it daily since March. My hair honestly looks shinier and fuller to me, and my stylist noticed before I said anything.

Tastes fine, easy habit
Mild flavor, easy to take. I take one dropper with breakfast. Knocking off a star only because I wish it came in a bigger bottle.

Staple in my beauty routine
The 40,000 mcg strength is why I picked this one, and the liquid format sealed the deal. On my third bottle.
