Part of my evening routine
Three capsules with dinner, every night for six months. Easy on my stomach where citrate was not.

Actually pure glycinate
A lot of "glycinate" products are secretly buffered with oxide. The lab certificate here shows the real form. That is why I pay more.

Three capsules is a lot
Wish the dose fit in two capsules. Otherwise no complaints — great quality for the price per serving.

Bought for the whole family
Compared four brands on this site and Ferra won on form and testing. Two months in, no regrets.
