The 300mcg capsule is a convent once a day dosage for my son. Hyperlink helps improve those functions. Relatively safe and devoid of side effects.

Great product. Works fantastic. Highly recommend this vendor/brand.

This product should not be used by anyone and should be panned. The pull off plastic lid seal was gone. Use caution on mixing huperine a with whole ingredient caffeine plant like coffee/tea/….

Organic, finely ground knotweed powder is very fine grained and has a strong taste. I mix it into almond milk with maca root powder to balances out the bitterness and this makes it taste more than tolerable.

The quality of this knotweed is very good and the packaging is fantastic. The product is just as it should be. Nicely packaged, easy to use, great price. It works well.

The product pictures have a “no wheat” icon but packaging does not say it is gluten free. If you try to make a tincture, a thick black sludge falls to the bottom of the jar.
