Most people don’t know about this powerful anti-aging secret.
Glycine is classified as a non-essential amino acid because the body can make it, but many people are still deficient. Most glycine in the diet comes from collagen, yet modern diets provide very little.
An ancestral diet included nose-to-tail eating with plenty of collagen, while today most people eat only lean, tender muscle meats. As a result, a large percentage of adults have chronically low glycine levels.
Glycine plays a critical role in red blood cell health, DNA and RNA production, bile salts, and glutathione, one of the body’s most important antioxidants. Your body prioritizes these essential functions first, which means other areas can become depleted.
Glycine is also vital for the immune system and quality sleep. When levels are low, your skin may not get enough support, contributing to visible aging. It also impacts fascia, tendons, cartilage, arteries, and the gut lining.
You don’t necessarily need a glycine supplement; just focus on increasing collagen intake instead. Add collagen to your coffee or a shake, and pair it with vitamin C to support absorption.

| 0:00.0 | I'm 61 years old, and I want to give you the best advice that I wish I knew in my 40s. |
| 0:07.0 | And most people don't know this, and this has nothing to do with avoiding starch, sugar, or seed oil, or missing a workout. |
| 0:16.0 | It's something much stranger. It's actually a nutrient deficiency. |
| 0:20.0 | And it's classified as non-essential. And I'm going to |
| 0:24.1 | tell you why that is, because it actually is very essential. And there's really no RDA on this at all. |
| 0:31.4 | But based on some hardcore data, we need like 15 grams per day. Our body makes three grams. In our diet most people get between |
| 0:40.3 | 1.5 and 2 grams, and that leaves us in the red or in the hole by 10 grams of this nutrient |
| 0:46.3 | every single day. So what is this nutrient? Glycine. And it's classified as non-essential merely because the body makes it. Any amino acid that |
| 0:58.4 | the body makes is considered non-essential, but they never asked how much do you actually need. |
| 1:04.2 | And here's what you need to know. You don't get a lot of glycine when you eat meat, |
| 1:08.4 | eggs, fish. Most of the glycine we get comes from collagen. And here's where the |
| 1:14.0 | problem is. Long ago, our ancestors consumed animals nose to tail. Now we don't eat nose to tail. |
| 1:20.1 | We do eat meat, but it's very tender, so it doesn't have a lot of collagen. An average tender steak |
| 1:25.8 | is like between one to two, maybe three percent |
| 1:29.3 | collagen. So it's a very tiny amount of collagen. But 30 percent of all of our body protein |
| 1:35.1 | is collagen. So the question is, where are we getting our collagen? Well, we're not. Glycine |
| 1:40.7 | is a foundational amino acid. It's the smallest amino acid. It's the oldest amino acid |
| 1:47.5 | dated back like 3.8 billion years ago. And one of the most respected nutrition scientists in this |
| 1:54.1 | field, Dr. Alan Jackson, out of the University of Southampton, he's written that there's 20 amino acids and only three |
| 2:02.2 | of them should be called non-essential and glycine wasn't part of the three. |
| 2:07.5 | But I'm going to tell you right now, 95% of adults are running on a shortage of this amino |
| 2:12.9 | acid chronically. |
