It helped with memory and concentration but caused headaches, which are reported as a possible side effect.

Although I have bought the root from an organic store in powder form and I was completely satisfied, I did not see any difference with this specific product. It is possible that the dosage indicated by the manufacturer of the product is small. I used to take 1 teaspoon of powder, which is equivalent to 5 grams.

Extremely effective!! My personal experience is:
After a week of taking it, with 2-3 pills a day (morning, noon, evening), I can see the difference. It's like the intensity and stress pass through a "filter" and everything becomes softer, more relaxed... The signs of stress have decreased in a week...
I realize how good it is when it runs out and I delay ordering again,
and I see the intense difference in stress signs again...
Everything comes back!!!

I bought 2 boxes after seeing the 2 reviews here that they are effective against stress and anxiety. I had been using another product with radish extract for a while, which was extremely effective. From the first days of using it, it caused me intense stress, weakness, and incredible insomnia. The product is extremely unsuitable for the promised use. I threw away one unused box and one that was 20 days old. I bought the previous one from a different brand again and found my health. We're talking about a crappy product.
