Buyer Decision Guide
The first decision is the molecule, not the price. Folic acid and 5-MTHF are separate products with separate labels and separate regulatory treatment in most markets. A quotation for folic acid is not a substitute for this grade.
The second decision is the salt. 5-MTHF is traded as a calcium salt and also as a glucosamine salt, and the declared salt changes the active content per kilogram. Ask which salt the quotation covers.
The third decision is the isomer. Only the L-form is the active one; the certificate should declare it, and a grade that does not state the isomer is a question rather than a bargain.
