Supports methylation, lowers homocysteine, and protects liver function.

Betaine (TMG) is a methyl donor that plays a critical role in the methionine cycle by helping to convert homocysteine back into methionine. This action helps lower potentially harmful homocysteine levels and supports the body's overall methylation capacity, a fundamental process linked to epigenetic regulation and cellular health.

Verdict

A safe, inexpensive way to support methylation and lower homocysteine.
