Metabolic Maintenance L-Methylfolate 2.5mg delivers active L-5-MTHF at the starting or maintenance dose for MTHFR support, methylation cycle support, and homocysteine management — a lower entry dose than the 5mg for patients beginning methylfolate supplementation or those requiring a lower dose. 90 capsules. Metabolic Maintenance is a physician-grade supplement manufacturer founded in 1984, formulating products exclusively with pharmaceutical-grade raw materials in clean, excipient-free capsules — no fillers, binders, colors, or artificial additives. Available at Beauty Riche with same-day shipping.L-5-MTHF bypasses the MTHFR conversion bottleneck completely — providing the immediately usable methylated folate form for the methylation cycle, neurotransmitter synthesis, and homocysteine remethylation. At 2.5mg, appropriate for daily maintenance, lower MTHFR variant severity (heterozygous vs. homozygous), or patients who are methyl-sensitive and require gradual dose introduction. Excipient-free.
