- Potential downsides of over-methylation
- Evidence-based supplementation
Key Moments
90% of methylation makes creatine, not nutrients
Gary Brecka popularized methylation but gets the biochemistry wrong. 90% of methylation synthesizes creatine and phosphatidylcholine.
"He is wrong about methylation. This stems from a poor understanding of basic biochemistry and leads to a misleading focus on just five genes."
