Folate, vitamin B12, vitamin B6.
No known serious interactions, but do not stack several "methylation" supplements without a reason.
Not suitable in pregnancy or breastfeeding due to lack of data. With chronic illness or when taking medicines, consult your doctor.
Long-term safety data are limited; do not exceed the label dose.
If homocysteine is your concern, betaine (TMG) and B vitamins have better evidence than DMG.
Strong = several good human studies or official recommendations; moderate = promising but smaller studies; weak = few studies or mixed results; no evidence = claims not confirmed.
