My doctor (in functional medicine) recommended L-Carnitine for me for the reasons of muscle mass (retaining it) and helping to maintain brain health, which are at least two of the benefits of this wonderful powder. The taste is not terrible, but it is not supposed to be sweet, so it is as it should be: tart. Excellent product for the price.

Been taking this for about six weeks. Energy is more consistent and I feel less sluggish in the afternoons. Happy with the purchase.

Third-party tested, clean label. That's what I look for first. Actually works too, which is a bonus.

Works well. Deducting a star because the bottle is hard to open with one hand, but the product itself is solid.

It's fine. Did what I expected, nothing more. Might try other brands before reordering.

Switched from a more expensive brand and honestly can't tell the difference in results. Saves money.
