5-MTHF powder (Vitamin B9)

L-5-MTHF-Ca is the calcium salt of L-5-methyltetrahydrofolate — the biologically active, ready-to-use form of folate that the body absorbs and utilizes directly, without requiring the enzymatic conversion step needed for synthetic folic acid. This makes it a preferred folate source for formulators targeting consumers with reduced MTHFR enzyme activity, a genetic variation estimated to affect a meaningful share of the population and increasingly recognized by both consumers and healthcare practitioners.

Supplied as a white to light-yellowish crystalline powder with an assay of 95.0–102.0% and active L-5-MTHF content of 72.0–87.0%, this ingredient is suitable for capsules, tablets, and powder blend applications, including prenatal, general wellness, and methylation-support formulations. It carries a 24-month shelf life and contains no declared allergens.

Formulators using L-5-MTHF-Ca as a folate source can draw on the well-established list of EU-authorized health claims for folate under Regulation (EU) 432/2012, including its contribution to normal blood formation, normal homocysteine metabolism, normal psychological function, reduction of tiredness and fatigue, normal function of the immune system, and its role in the process of cell division — provided the finished product meets the required minimum folate content per the claim conditions.

We provide complete traceability and full documentation — Certificate of Analysis, heavy metal and microbiological testing, and independent third-party lab testing on request — with every batch.
