Quatrefolic® Methylfolate
Support methylation via healthy homocysteine & SAM-e levels*
Quatrefolic® methylfolate is the fully activated, glucosamine salt form of methylated folic acid (5-MTHF), for optimal absorption and utilization in the body. Folate is an essential water-soluble B vitamin (B9) that vitally supports our heart, brain, cellular energy, and synthesis of amino acids, DNA, RNA, and red blood cells. In its bioactive form, folic acid is clinically shown to support healthy homocysteine and SAM-e levels to drive optimal methylation in every cell.*
Riboflavin (Vitamin B2)
Antioxidant & cofactor for MTHFR enzyme*
Our riboflavin 5’-phosphate is the fully bioactive form of this essential water-soluble micronutrient. Riboflavin (vitamin B2) is a precursor for major coenzyme flavoproteins in the body, a required cofactor for the MTHFR enzyme, and thus, folate metabolism and methylation. In addition to antioxidant and immune functions, vitamin B2 is also required for the production of niacin, vitamin B6, red blood cells, and ATP energy from the foods we consume each day.*
Vitamin B6
Drive amino acid synthesis & folate metabolism*
Our vitamin B6 is in the bioactive pyridoxal 5’-phosphate form. This vitamin is a cofactor for 100+ enzymes in our body, particularly those essential to amino acid synthesis, energy and neurotransmitter production, antioxidant and immune function, plus protein and folate metabolism (key to methylation). Vitamin B6 helps maintain healthy homocysteine levels via conversion to cysteine, which serves as a building block for collagen, keratin, and glutathione.*
Vitamin B12
Promote ATP energy & efficient methionine cycle*
Our methylated vitamin B12 (methylcobalamin) is the bioactive form of this pivotal nutrient that is whole-body relevant. It’s required for cellular energy, plus the formation of DNA, red blood cells, neurons, neurotransmitters, and antibodies. B12 serves a complementary role with folate in the methionine cycle, as they are both essential cofactors for one-carbon metabolism, optimal homocysteine recycling to methionine, and methylation.*
Betaine
Ensure homocysteine conversion & major methyl donor*
A methyl derivative of the amino acid glycine, betaine (i.e., trimethylglycine) is a critical bioactive for lipid and energy metabolism, plus osmoregulation. Betaine is most famous for being a major methyl donor in the body, as it ensures homocysteine's conversion to methionine. In fact, high-potency betaine has been clinically shown to support homocysteine reduction and methionine regeneration, ultimately driving methylation function and health.*

This is the complex I recommend for daily methylation support because it's optimized for bioactivity and efficacy.*
