How to use Nutricost L-Carnitine Tartrate

When to take it

Take it daily. Many people take it with a meal on training days, as L-carnitine tartrate is the form most studied for exercise recovery.

How to take it

The label serving is two capsules (1,000mg of L-carnitine tartrate). Take it with food; some research suggests carnitine is taken up into muscle better alongside carbohydrates. Up to 2,000mg a day is common, split into two doses.

What to combine it with

Mainly used as a workout supplement rather than a nootropic. If your goal is focus, acetyl-L-carnitine is usually the better choice. Avoid stacking several carnitine products.

About L-Carnitine

L-carnitine is a nutrient your body makes from the amino acids lysine and methionine, and gets from red meat. It carries fatty acids into the mitochondria to be burned for energy. Acetyl-L-carnitine (ALCAR) crosses into the brain more readily and is the form usually chosen for focus; L-carnitine tartrate is the form most studied for exercise recovery.

Typical dosage: Acetyl-L-carnitine is typically taken at 500mg to 1,500mg per day, and L-carnitine or L-carnitine tartrate at 1,000mg to 2,000mg per day. Larger amounts are often split into two doses with food to avoid stomach upset.

Things to know: High doses can cause nausea, diarrhea or a fishy body odor. Talk to a doctor first if you have an underactive thyroid or take thyroid medication, take blood thinners such as warfarin, have a history of seizures, or have kidney disease.
