膠原蛋白胜肽

The powder dissolves cleanly in my morning coffee with no clumps, which was my main worry with collagen. After three weeks of daily use, my nails are noticeably harder and I don't have that mid-afternoon joint stiffness anymore.

I was skeptical about adding another powder to my morning routine, but the unflavored peptides dissolve cleanly in my coffee with zero grit. The standard size has lasted me over a month, so the value feels right.

After about three weeks of using this in my smoothies, I finally noticed my nails stopped breaking so easily. The powder dissolves completely clear, which surprised me since I half-expected a chalky aftertaste.
