What it is
Betaine, also known as Trimethylglycine (TMG), is a compound that acts as a methyl donor. In the context of cardiovascular health, it is primarily used to support the body's homocysteine metabolism.

How it works
Betaine facilitates the remethylation of homocysteine to methionine, a critical step in the methionine cycle. Elevated homocysteine is a recognized risk factor for cardiovascular disease. Betaine's methyl-donating capacity helps manage these levels.
Who should take it
Adults looking to address high blood pressure, poor circulation, high cholesterol. Particularly relevant for people who prefer a targeted single ingredient and who have ruled out an underlying condition that needs medical care first.
Avoid / careful
Pregnant or nursing women without clinician oversight. People on prescription medication affecting the same pathway should consult a doctor before combining. Side effects are uncommon at recommended doses but mild GI upset can occur when starting.

FAQs
Frequently asked
How does Betaine (TMG) help with homocysteine?
Betaine donates a methyl group to homocysteine, converting it into the amino acid methionine. This process is vital for managing homocysteine levels, which are linked to cardiovascular risk.
Can Betaine (TMG) be taken with other supplements?
Yes, Betaine (TMG) can be layered with other supplements. However, if you are on prescription medication affecting homocysteine or methylation, consult your doctor.
What is the typical onset of effects for Betaine (TMG)?
Measurable cardiovascular markers may become apparent within 4 to 12 weeks of consistent daily use.
