Most people are glycine-deficient. Why? Because stress, processed food, trauma, and too much methionine (muscle meat) drain glycine FAST. This leads to: •Anxiety •Sleep issues •Joint pain •Chronic inflammation •Overthinking •Emotional shutdown That’s why I take 2 scoops

Your body needs glycine to make GABA — your “calm chemical.” Without enough glycine, your brain stays hypervigilant. You stay reactive. Tense. Wired. Even if you meditate.

Here’s what glycine can do: •Lower cortisol •Deepen sleep •Reduce intrusive thoughts •Soothe emotional flashbacks •Support vagus nerve repair •Help process stored trauma It’s like giving your nervous system a warm blanket and saying: “You’re safe now.”

Trauma lives in the nervous system. Glycine helps rewire it. It’s not a “cure” — but it gives your body the safety signal it’s been waiting for. I trust @CentenariusN products, not just is the owner J one of my best friends and actually my best man in my wedding but also does
