What actual customers report
Smart to include the copper
Most zinc products I've bought don't even mention copper depletion risk. Appreciated the transparency about why the ratio matters.
Amanda G. — Zinc Bisglycinate + Copper
Pairs perfectly with my morning coffee
This is exactly the caffeine-smoothing stack I was trying to DIY with separate L-theanine and Alpha-GPC bottles. Convenient to have properly dosed together.
Kevin O. — L-Theanine + Alpha-GPC Stack
Helped with sleep onset too
Wasn't expecting a sleep benefit but I fall asleep faster on nights I take it consistently.

Every batch. Every certificate. On record.
