Ingredients explained
Betaine anhydrous (Trimethylglycine)
Provides methyl groups to support homocysteine remethylation and overall methylation balance.
Caution: May cause stomach upset in some people; take with food if sensitive.
Vitamin B12 (as Methylcobalamin)
Acts as a cofactor for methionine synthase, helping convert homocysteine to methionine and supporting methylation-dependent processes.
Caution: High doses may be stimulating for some individuals; avoid taking close to bedtime if sensitive.
Folate (as L-5-Methyltetrahydrofolate)
Delivers the active folate form used in one-carbon metabolism to donate methyl groups and support DNA and neurotransmitter synthesis.
Caution: Consult a health professional before use during pregnancy or when taking medications that interact with folate status.
Vitamin B6 (as Pyridoxal 5'-Phosphate)
Functions as an active coenzyme in amino acid metabolism, including transsulfuration pathways related to homocysteine balance.
Caution: Long-term high intakes may be associated with nerve tingling; follow suggested use.
Riboflavin (as Riboflavin 5'-Phosphate)
Provides the active form of vitamin B2 that supports redox reactions and the folate cycle enzymes involved in methylation.
Caution: May cause bright yellow urine due to riboflavin excretion; this is harmless.
How they work together
Trimethylglycine and methylcobalamin donate and transfer methyl groups to help remethylate homocysteine. L-5-methyltetrahydrofolate supplies the active folate used in one‑carbon metabolism, while PLP (B6) and R5P (B2) act as active coenzymes that help drive folate and amino acid pathways for efficient methylation.
Safety and tips
Label Warning: If pregnant, consult a healthcare practitioner before use.
Who should be cautious: People with high vitamin B intake sensitivity or those with a history of vitamin-related neuropathy may want to discuss the high-dose B vitamins with a healthcare provider before use.
Storage: Store tightly sealed in a cool, dry place.
