If you're looking for folate support without the synthetic form, this liquid **Folinic Acid** delivers 400mcg per drop (667mcg DFE), landing right at the RDA and within the 400–800mcg clinical range. Folinic acid is a naturally occurring form of folate that your body can use without the same conversion steps required by synthetic folic acid — making it a practical option if you want to avoid standard folic acid.
The liquid drop format gives you flexible dosing, and with 800 servings per bottle, you're looking at over two years of daily use. The base is just glycerin and water, keeping inactive ingredients minimal.
One consideration: folinic acid is not the same as methylfolate (5-MTHF), which is the directly active coenzyme form. If you specifically need methylfolate due to MTHFR gene variants, folinic acid still requires a conversion step — though it bypasses the main bottleneck that folic acid hits.
