Stack Genius ingredient guide
Betaine
Betaine is trimethylglycine, a methyl donor and osmolyte distinct from Betaine HCl in supplement labeling.
Overview
Betaine is trimethylglycine, a methyl donor and osmolyte distinct from Betaine HCl. TMG is a different supplement story than Betaine HCl.
Confirm anhydrous/TMG form, grams per serving, and methylation-stack context. Brands usually frame it around performance, homocysteine, and methylation-positioned formulas.
form confusion, GI effects, cholesterol context, and overlap with methylated B vitamins. GI effects, methylation stacks, cholesterol context, and kidney disease deserve caution.
Key takeaways
- Betaine: Confirm anhydrous/TMG form, grams per serving, and methylation-stack context.
- Tribulus research does not justify strong testosterone language, so the product details carry most of the value.
- GI effects, methylation stacks, cholesterol context, and kidney disease deserve caution.
