No stress, healthy sleep

Glycine is an amino acid that supports healthy sleep & mental health. This supplement contains glycine powder. Dosage: 1 scoop = 1 g. A scoop's included in the package. I can say from my experience that this supplement works. Benefits: improves sleep, relaxes, calms. I mixed 1 scoop (1 g) in water & took it 60 minutes before bedtime for 1.5 months. This white powder dissolves easily & quickly in water. It tastes good. Odorless. Container contains 227 servings (package quantity: 227 g). Container material: plastic. Be healthy!

Great!

Calming, clean, and highly effective for sleep and nervous system This glycine powder has become a staple in my nightly routine. I take it in the evening — either on its own or mixed with warm water — and it noticeably helps me feel more relaxed, calm, and ready for sleep. It’s also been amazing for reducing inner tension and overthinking. The powder dissolves well, has a mildly sweet natural taste (no added flavors), and feels very clean. I appreciate that it’s pure, without unnecessary fillers. It’s also great for liver support, collagen synthesis, and nervous system balance — definitely a multitasker!

Great quality and helps me sleep!

I’m really impressed! The powder mixes easily into water and has a slightly sweet taste. So much easier to relax and fall asleep and actually stay asleep at night after taking this. It also seems to help with muscle recovery after workouts. Excellent quality overall. I’d definitely recommend it to anyone looking to improve sleep!

Ajipure Glycine = Pharmaceutical grade = the best quality Glycine

I’ve tried several glycine brands, but Swanson’s Ultra Glycine with AjiPure® is hands-down the best quality I’ve found. Because it uses AjiPure, you're getting pharmaceutical-grade amino acids from Ajinomoto, which is the gold standard for purity. I take this about 30–60 minutes before bed, and it has drastically improved my sleep quality. It helps me fall asleep faster and wake up feeling refreshed rather than groggy. The powder version has a naturally mild, sweet taste and dissolves perfectly in water without any weird fillers. If you care about ingredient purity and want a supplement that actually works for recovery and sleep, this is the one to get.

Amazing!

I started taking this because I was reminded how important it is on Dr Paul Anderson’s YouTube channel. It helps me to relax and fall asleep but I also noticed that my mouth felt cleaner when I woke up. I did some research and apparently it helps the oral microbiome as well. Who knew? So an absolute win-win for me. Also this one is Anji-pure, which assures quality and purity. I always look for that in all of my amino acid supplements because it makes a huge difference that I can feel. I always check because not every amino by a particular brand may have it or not.
