A scientist Dr.Mitchell from USA extracted around 1mg active folate from four tons of spinach successfully in 1943. However, the chemical property is too active to be stored. “How to make the active folate be stable?” has been a global difficulty since 1943.

What our body really need is L-5-MTHF( L-5-Methyltetrahydrofolate ). But we can’t absorb it directly. Later, scientist made it into salt form. When we eat salt L-5-MTHF, it will be dissolved into Ionic form and be absorbed by ionic channel in our body. The most popular salt form is Calcium salt.


Magnafolate® is the patent protected C crystalline L-5-Methyltetrahydrofolate Calcium salt (L-5-MTHF Ca) which is invented by Jinkang Pharma from China in 2012, produced under US Patent No. 9,150,982 B2. The preparation of the Calcium salt and the crystal type C solved the stability problem completely.


Magnafolate® has the highest purity more than 99%, and controls some potential risky impurites to the smallest assay.
Such as Mercury 0.1ppm, 15 times less than USP standard 1.5ppm
JK12A 0.1% , 10 times less than USP standard 1.0%
D-5- Methyltetrahydrofolate 0.1%,  10 times less than USP standard 1.0%
Importantly, we avoid using the toxic raw material of formaldehyde during production process compared to other marketing  generic L-methylfolate.


Magnafolate® PRO is the most friendly and safe folate source for mother and kids. Here is a warm viedo, well worth seeing.  https://youtu.be/gSR1KsUseuU
