L-Carnitine supposedly helps convert fat into energy and provides numerous benefits, the powder mixes in ok, I typically mix using a 21 fl oz sports bottle, initially I did notice particles sink to the bottom even with vigorous shaking, so I found letting it sit for a minute in water, then re-shaking will help it fully dissolve, the cherry lime flavor is pleasant to drink and is not too sweet or tart, a scoop is provided so it's very easy to use, currently I use carnitine for sports like hiking and mountain biking so far it seems to be effective as I have noticed nice stable energy levels, luckily this has been agreeing with me perfectly with no stomach issues or side effects.This supplement is caffeine-free and uses two sources of l-carnitine, N-Acetyl L-Carnitine Hydrochloride (1500 mg) and L-Carnitine L-Tartrate (1500 mg) for a total of 3000 mg of l-carnitine per serving, I was somewhat disappointed it contains an artificial sweetener sucralose, but I do like that it uses natural flavors and is naturally colored (beet root powder).Overall I recommend, great flavor, made in the USA, a lot number and exp date is printed on the bottom, provides 30 servings.
