The endurance carnitine.
L-carnitine is typically added to sports supplements because of its rapid absorption rate. Human studies suggest Carnitine Tartrate may promote cardiovascular endurance.
Benefits of Carnitine Tartrate
It is mostly seen in pre or intra-workouts, but be careful of combining it with other hygroscopic ingredients like betaine. So, use it in dry formulas. Also, it may aid muscle soreness and recovery in exercise. This form of l-carnitine is most effective for exercise performance.
Like the other carnitines, Carnitine Tartrate is highly soluble in water, hygroscopic, but still usable in powder applications.
Because it consists of ~45% Carnitine, it is less hygroscopic than Carnitine Base and usable in powder applications. Doses may vary from 1,000-4,000 mg per day.
