Spring Valley Biotin & Collagen Liquid, 1 fl oz, 15000 Mcg, Natural Berry Flavor

Honestly, this stuff is delicious. At first, I was skeptical, wondering how anything this good could actually be packed with beneficial vitamins. But here's the delightful truth: after about a week of consistent use, I began to notice tangible results. My nails are undeniably stronger, and my complexion has a subtle, healthy glow. While it's certainly not a "miracle cure" (because, let's be realistic, those don't exist in a bottle!), the Biotin component genuinely seems to add a slight pep to my overall energy. A quick, important tip for new users: don't be alarmed if the dropper doesn't fill completely. You're getting the correct, effective dose with just a single squeeze. There's no need to take more, as overdoing it can lead to an upset stomach – trust me on that one! And did I mention it's delicious? Because it absolutely is. This liquid supplement has made wellness a genuinely enjoyable part of my daily routine.

I love this stuff. I at one point was using powder then found this. It's easy to use but you may have to do a double squeeze on the dropper. No measurements but that's ok for me I just use a a full dropper amount. I noticed my little flexibility nail are much thicker and don't peel when I use collagen vs not using. I just put this in my coffee in the morning or anything that I maybe drinking for that matter. I did notice that it requires a little bit of swirling action with whatever you are drinking to break it up otherwise it will remain a purple glob at the bottom of the container. So I add swirl (usually with a liquid sweetener) till it is dissolved and add coffee (I usually normally add in liquid b complex to get those vitamins also) then drink said coffee. On its own it does have the slight berry taste I just prefer to sip on it throughout the morning. Have already recommended to several people. Been using for several years
