The actual amount of active ingredient is minuscule. In order to form something that looks to be worth the price, many fillers and binders must be used. I wouldn't worry about any negative effects from them.

Huperzine A - 120 X 200 Mcg Tablets

Q: Why has the price gone up 25% since November 2017?

Hello, We launch products on Amazon at a loss in order to generate sales and rankings. After we launch we slowly raise the price over the course of a couple months to a profitable point. Best Regards, -Caroline Double Wood Supplements

Q: Does the herb come from China?

To the best of my knowledge, it is extracted from a root common to China.

Q: what is third party tested?

Hello, We have sent the product to Health Level One for testing (A third party we are not related to). Their testing shows there is approx 200mcg of Huperzine A in each tablet they tested. Best Regards, -Caroline Double Wood Supplements
