With NutraBio LeanShots L-Carnitine 3000, you skip much of the process by already providing your body with a readily absorbable liquid form

Note that supplemental L-carnitine (doses, 0.6-7.0 g) is less efficiently absorbed compared to smaller amounts in food

Another randomized placebo-controlled trial in 2,330 patients with acute MI, L-carnitine therapy (9 g/day intravenously for five days, then 4 g/day orally for six months) did not affect the risk of heart failure and death six months after MI (50)

Skeletal muscle wasting Loss of skeletal muscle mass is associated with a decrease in muscle strength and occurs with aging (119), as well as in several pathological conditions (120-122)

Intravenous administration is more likely to increase plasma carnitine concentration, yet homeostatic mechanisms tightly control blood concentration through metabolism and renal excretion: Up to 90% of 2 g of L-carnitine administered intravenously is excreted into the urine within 12 to 24 hours
