Most people focus on protein for muscle growth, but not all amino acids are created equal and glycine deserves way more attention.
Glycine is a non-essential amino acid, meaning your body can make it but often not enough to meet your needs, especially if you’re dealing with stress, poor sleep, or gut issues. So, what are the benefits of glycine?
✔ Better Sleep & Relaxation – Glycine lowers core body temperature and increases serotonin, helping you fall asleep faster and stay in deep sleep. Studies show 3g before bed can improve sleep quality without grogginess.
✔ Stress & Cortisol Balance – Glycine acts as a calming neurotransmitter, reducing anxiety and keeping cortisol (your stress hormone) in check. This makes it especially helpful if you struggle with burnout, adrenal fatigue, or PMS.
✔ Gut Health & Detoxification – Glycine protects the gut lining, making it beneficial for leaky gut, IBS, or bloating. It also supports liver detox by helping the body produce bile and glutathione (a powerful antioxidant).
✔ Collagen & Skin Health – Nearly one-third of collagen is made of glycine! This means stronger joints, healthier skin, and faster wound healing.
You can find it in bone broth, collagen, gelatin, meat, and seafood. Supplementing with glycine powder can be especially helpful for sleep, gut repair, and stress resilience. Speak with your healthcare provider for tailored supplement recomendations.
