top-tier folate supplement

Highly recommend! I chose this because it contains the active form of folate (Quatrefolic), which is easier for the body to absorb compared to regular folic acid. The capsules are small and easy to take, and I noticed improvements in my energy and overall well-being. It’s also great that it’s vegan and free from unnecessary additives. Excellent quality for the price—will definitely repurchase!

Great!

I mix it with juice, and my kid loves it. I don't know how much this is effective, but I see improvement in my child progress. he is more verbal and makes great conversations with us. if you mix it with water or juice, the kid won't feel the taste.

priced right

Drs Best is a trusted brand, and this bottle offers value that many other brands and bottle sizes do not. Price is foremost the first thing that applies to this purchase and as far as trusted brands for Drs Best is the best value in the market hands down, all others do not match the value in quality pricing and value. Each capsule contains a small amount of vitamin C to keep this more unstable form of folate from going over exposed to oxygen, the vitamin C is a quality additional ingredient.

Great Folate Supplement for TTC

My husband and I have been taking Doctor's Best Fully Active Folate with Quatrefolic while trying to conceive, and it's been a great addition to our routine. The Quatrefolic form is highly bioavailable, making it easy for the body to absorb, which is crucial for those preparing for pregnancy. Unlike other folate supplements I've tried, it's gentle on the stomach and doesn't cause discomfort. The capsules are small and easy to swallow, and we feel confident about the quality. Definitely a solid choice for anyone in the same situation!

The best active form of folate for absorption

I switched to Doctor's Best because it uses Quatrefolic, the active MTHF form. Unlike standard folic acid, this doesn't need to be converted by the body, which is essential for those with MTHFR variations. I’ve noticed a steady improvement in my energy levels and overall well-being since starting. The veggie capsules are small, easy to swallow, and very gentle on the stomach with no side effects. Great value for a 3-month supply!

Under test

I’m still trying it, but so far it seems good. The quality feels reliable and the packaging is clean and practical. The size is convenient and easy to take daily. There’s almost no noticeable smell, which I like. I’ll keep using it and see how the results go, but overall my first impression is positive
