Great

I began taking L-Serine because I wanted something that might help with concentration and mental sharpness. After a few weeks, I’ve noticed my mind feels a little more alert, and I don’t hit that same mid-afternoon slump as often. The capsules go down easily and haven’t caused me any issues. It’s a subtle difference, but enough that I feel it’s worth continuing.

Great addition to my daily supplement routine

I’ve been taking L-Serine daily and I’m really impressed with it so far. I find it easy to take, it’s well tolerated, and it fits nicely into my existing supplement routine. I particularly like that it doesn’t feel overly stimulating or disruptive, while still feeling like a useful addition to my overall wellbeing and daily routine. The powder is also convenient to incorporate into my morning routine. Overall, a quality product that I’m happy to keep using. I’d definitely recommend it to anyone looking to add L-Serine to their supplement stack.

L-serine

This product is really helpful for sleep. It's very gentle and helps me get deep sleep despite having C-PTSD. It's more gentle than phosphatidyl serine.
