NOW Foods Acetyl-L-Carnitine, 500mg

Fifty, one hundred or two hundred veg capsules: NOW Foods sells its Acetyl L-Carnitine in three bottle sizes, each capsule carrying the 500mg figure stated on the label. Acetyl L-carnitine is the acetylated form of L-carnitine, a compound long familiar to supplement users.

The vegetarian capsule format is standard across much of the NOW range, and the three-size spread means the line scales from a low-cost trial to a long-running supply. As ever with NOW, the label is plain and the ingredient list is short.
