Works well. Deducting a star because the bottle is hard to open with one hand, but the product itself is solid.
Been taking this for about six weeks. Energy is more consistent and I feel less sluggish in the afternoons. Happy with the purchase.
Good quality supplement. About three weeks in and noticing a difference, mostly in energy levels.
Third-party tested, clean label. That's what I look for first. Actually works too, which is a bonus.
Solid formulation. A bit pricey but I think it's worth it for the label transparency.
