What customers say
Customers have reported significant benefits from using this folinic acid supplement, particularly in reducing homocysteine levels and improving mental clarity, concentration, and energy. Many users prefer folinic acid over regular folic acid due to its better bioavailability and fewer side effects. The product is praised for its high quality, reasonable price, and quick delivery by iHerb. Several customers mentioned that it was recommended by their doctors for various health concerns including stress, anxiety, and MTHFR gene mutation. The supplement has been effective in enhancing mood, metabolism, and overall well-being without any adverse effects. Users appreciate the convenient packaging and neutral taste of the tablets.

Supposed to be helpful in certain conditions.
Verified purchase
I'm not quite sure about this. It is supposed to be really helpful in certain conditions where you can't get enough folic acid into your brain. I cannot say that I really noticed much of a difference so far. Maybe I haven't taken it long enough or maybe not enough. I'm just not sure.

Good quality, hard to give to kids.
Verified purchase
I bought this for my child with autism, but it is hard to give because it comes in tablet form. Because of the difficulty in taking it consistently, I did not clearly see any results yet. The quality seems good, but I wish it was available in a liquid or chewable form for kids .

Heard good reviews about folinic acid and tried it on my child. So far, there is no improvement in his energy or anything else. The package is smaller than I thought.

You need to take it separately, with no additional ingredients. It’s good for immunity and has no taste. The size is sufficient and lasts a long time. The dosage and effects are good, the packaging is high quality, and it doesn’t cause acidity or stomach issues. It has strong antioxidant properties. I recommend using it after consulting your doctor.

Love it! high quality product for a nice price and it's enough for a long time. It's my 3rd packaging that I'm buying. I love the effect it gives - boosts with energy and at the same time gives clarity in my head. I will definitely buy it again.
