The Best Anti-Aging Advice I Wish I Knew

Dr Eric Berg · 14 May 2026 · 4 Egleze moments

What happened in this episode?

In this health-focused monologue, the speaker delivers a detailed argument that glycine—an amino acid officially classified as non-essential—is chronically deficient in 95% of adults, causing widespread health problems ranging from inflammation to premature aging. The speaker, identifying as 61 years old, frames glycine deficiency as a hidden epidemic stemming from modern dietary shifts away from nose-to-tail animal consumption. While the body produces 3 grams of glycine daily and diets provide 1.5-2 grams, the speaker claims humans require 15 grams per day, creating a 10-gram daily deficit. The episode systematically explains how the body triages glycine, prioritizing red blood cells, DNA, RNA, and bile salts while starving lower-priority functions like immune regulation, skin integrity, cartilage repair, and arterial health. The speaker cites Dr. Alan Jackson of the University of Southampton, who reportedly argues glycine should not be classified as non-essential. Personal testimony includes severe arthritis at 28, chronic bone fractures, and sleep problems attributed to glycine deficiency from a junk food diet lacking collagen. The speaker controversially claims even carnivore dieters can be glycine-deficient if consuming only tender steaks rather than collagen-rich nose-to-tail eating. The episode concludes with a recommendation for collagen powder supplementation paired with vitamin C, and promotes the speaker's own supplement line and a quiz to identify metabolic dysfunction.

What are the key points?

Speaker claims 95% of adults are chronically deficient in glycine by 10 grams daily due to loss of nose-to-tail eating.
Dr. Alan Jackson of the University of Southampton reportedly argues glycine should not be classified as non-essential despite official designation.
Glycine deficiency causes macrophages to fail at turning off inflammation, leading to chronic conditions treated with unnecessary medications.
Carnivore dieters consuming only steak may be glycine-deficient since tender meat contains just 1-3% collagen versus historical nose-to-tail diets.
Body triages glycine to survival functions like red blood cells and DNA first, starving immune function, skin, cartilage, and arterial health.
Speaker attributes personal history of severe arthritis at 28, bone fractures, and insomnia to glycine deficiency from junk food diet.
Standard protein sources like meat, eggs, and fish provide minimal glycine; collagen from connective tissue is the primary dietary source.

Researcher Argues Glycine Should Not Be Classified as Non-Essential Nutrient

at 1:36 · Attributed speaker claim

One of the most respected nutrition scientists in this field, Dr. Alan Jackson, out of the University of Southampton, he's written that there's 20 amino acids and only 3 of them should be called non-essential. And glycine wasn't part of the 3.

Citing Dr. Alan Jackson from the University of Southampton, the speaker challenges the official classification of glycine as non-essential, arguing the designation is based solely on the body's ability to produce it rather than actual sufficiency. This represents a fundamental critique of nutritional science standards that overlook the gap between endogenous production and physiological needs.

Nutritionist Claims 95% of Adults Chronically Deficient in Critical Amino Acid

at 1:50 · Attributed speaker claim

95% of adults are running on a shortage of this amino acid chronically. Our body makes 3 grams. In our diet, most people get between 1.5 and 2 grams, and that leaves us in the red or in the hole by 10 grams of this nutrient every single day.

The speaker argues that glycine, classified as non-essential, is actually critically deficient in nearly all adults at a shortfall of 10 grams daily. The deficiency stems from modern diets abandoning nose-to-tail eating, which provided collagen—the primary source of glycine—while standard meat, eggs, and fish provide minimal amounts.

Chronic Inflammation Linked to Glycine Deficiency in Immune Cells

at 5:55 · Attributed speaker claim

When the macrophage dies, it releases glycine to turn off the inflammatory switch. But if there's not enough glycine in the macrophage, there's nothing that turns off the inflammation. And then they end up on medications when they don't know deeper underneath the hood they need more glycine.

The speaker reveals that macrophages, frontline immune cells, require glycine to release anti-inflammatory signals when they die. Without adequate glycine, inflammation remains uncontrolled, leading patients to unnecessary medications while the underlying nutrient deficiency goes unrecognized.

Carnivore Diet May Cause Glycine Deficiency Despite High Meat Consumption

at 9:15 · Attributed speaker claim

Even when someone becomes a carnivore and consumes mostly steak and they don't consume nose to tail, they can also be deficient in glycine. Meat, by the way, is very low in glycine. It's high in other amino acids but not glycine.

The speaker challenges popular carnivore diet assumptions by revealing that standard steak consumption provides insufficient glycine despite adequate protein. This contradicts the belief that meat-heavy diets automatically supply all essential nutrients, as modern tender cuts contain only 1-3% collagen compared to traditional nose-to-tail eating.
