L-Carnitine , a naturally occurring non-essential amino acid which boosts its own production when combined with Vitamin C. L-carnitine transports fatty acids like triglycerides into the mitochondria and converts it into energy. Its antioxidant properties are believed to affect the heart muscles positively. L-cartinine deficiency is a rare case. However, fatigue, muscle-cramps and pre-mature aging are some of its deficiency signs. L-carnitine is highly found in dairy products and red meat. In foods like legumes, nuts, grains, fresh fruits, vegetables and cereals although the level of L-caritine is not high, it promotes production. L-carnitine is not known to cause any toxic effect, but an overdose of carnitine i.e. 1000mg daily can cause diarrhea, stomach cramps, nausea and vomiting. Research prove that adding L-carnitine to our daily diet increases metabolism promotes weight loss and maintains a healthy level of blood glucose.
