L-Carnitine Supplements

L-carnitine supplements are available as capsules, tablets, powders and liquid formulas, either alone or combined with other sports-nutrition ingredients. L-carnitine is one of the main supplemental forms of carnitine, a substance the body also produces and uses in the process of converting food into energy. Healthy people normally make the carnitine they need, and no recommended daily intake has been established. Compare the amount per serving, number of daily servings, added stimulants, sweeteners and allergens. Research into athletic performance and weight management has produced mixed results, so these products should not promise guaranteed fat loss or improved performance. Intake of three grams or more per day may cause nausea, diarrhoea, stomach cramps or a fishy body odour, and professional advice is appropriate for people with kidney or seizure conditions.
