同義語： L-5-Methyltetrahydrofolate Calcium, Calcium L-5-Methyltetrahydrofolate, L-5-MTHF Calcium, (6S)-5-Methyltetrahydrofolate Calcium Salt, Levomefolate Calcium, Metafolin® (Calcium Salt), L-5-Methyltetrahydrofolic Acid Calcium Salt, (6S)-5-Methyl-5,6,7,8-tetrahydrofolic Acid Calcium Salt

L-5-Methyltetrahydrofolate Calcium (L-5-MTHF Calcium) is the naturally occurring, biologically active form of folate. It is the primary circulating form of folate in the human body and serves as the direct methyl donor for the remethylation of homocysteine to methionine, a critical step in the regulation of homocysteine levels and the synthesis of S-adenosylmethionine (SAMe), a universal methyl donor involved in numerous biological processes.

Unlike synthetic folic acid, which requires hepatic conversion via dihydrofolate reductase (DHFR) to become biologically active, L-5-MTHF is immediately bioavailable and does not require enzymatic reduction. This is particularly significant for individuals with genetic polymorphisms in the MTHFR (methylenetetrahydrofolate reductase) enzyme, who may have reduced capacity to convert folic acid to its active form.

L-5-MTHF-Calcium

The calcium salt form provides enhanced stability and allows for consistent formulation in dietary supplements and pharmaceutical products.

Calcium L-5-Methyltetrahydrofolate VS Folic acid

機能

• Active folate form: Provides immediately bioavailable folate without requiring hepatic conversion.

• Homocysteine regulation: Acts as a methyl donor for remethylation of homocysteine to methionine.

• Methylation support: Supports the production of SAMe, essential for DNA methylation, neurotransmitter synthesis, and cellular function.

• Neural tube defect prevention: Essential for healthy fetal development during pregnancy.

• 心血管の健康: Helps maintain healthy homocysteine levels.
