The Claim
Glycine and serine supplementation in Caenorhabditis elegans induce widespread transcriptional repression of genes involved in growth, development, and morphogenesis, with 2,629 and 2,865 genes downregulated respectively, suggesting a conserved mechanism of lifespan extension through suppression of anabolic processes.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In the worm Caenorhabditis elegans, supplementation with glycine and serine reduces the activity of thousands of genes related to growth and development, and this reduction is associated with extended lifespan through decreased anabolic activity.

When glycine or serine is present, the body converts them into a molecule that fuels the production of a methyl donor. This methyl donor attaches chemical tags to DNA-packaging proteins, which shuts down genes that build tissues and drive growth. With these growth genes turned off, the body shifts energy away from development and toward maintenance, which slows aging and extends life.
What the research says
1 studyStudy: Glycine promotes longevity in Caenorhabditis elegans in a methionine cycle-dependent fashion
When scientists gave tiny worms glycine or serine, their bodies turned down hundreds of genes that build and grow tissues, which seems to help them live longer by saving energy. This matches what the claim says.
