Surprising Findings

TMAO increased by 63% (0.27 to 0.44 µg/mL), though not statistically significant (P = .053), raising a red flag.

Betaine is often marketed as a 'clean' supplement, but TMAO is a compound linked to heart disease—so even a non-significant rise is concerning and counter to assumptions.

Practical Takeaways

If you're a healthy active male taking betaine supplements, you’re likely increasing your serum betaine and slightly lowering homocysteine—especially if you have the MTHFR T-allele.
