Carnitine blood levels and muscle stores can become low, which may contribute to anemia, muscle weakness, fatigue, altered levels of blood fats, and heart disorders. Some studies have shown that supplementation of high doses of l-carnitine (often injected) may aid in anemia management. Sources
The form present in the body is l-carnitine, which is also the form present in food. Food sources rich in l-carnitine are animal products, particularly beef and pork. Red meats tend to have higher levels of l-carnitine. Adults eating diverse diets that contain animal products attain about 23-135 mg of carnitine per day. Vegans get noticeably less (about 10–12 mg) since their diets lack these carnitine-rich animal-derived foods. Approximately 54% to 86% of dietary carnitine is absorbed in the small intestine, then enters the blood. Even carnitine-poor diets have little effect on total carnitine content, as the kidneys conserve carnitine. In general, omnivorous humans each day consume between 2 and 12 µmol kg−1 of body weight, accounting for 75% of carnitine in the body. Humans endogenously produce 1.2 µmol kg−1 of body weight of carnitine on a daily basis, accounting for 25% of the carnitine in the body. Strict vegetarians obtain little carnitine from dietary sources (0.1 µmol kg−1 of body weight daily), as it is mainly found in animal-derived foods.L-Carnitine, acetyl-l-carnitine, and propionyl-l-carnitine are available in dietary supplement pills or powders, with a daily amount of 0.5 to 1 g considered to be safe.

Pregnancy
Previous episode(s) of erysipelas

Traumatic wounds
Venous insufficiency or disease

Preventative measures
Individuals can take preventative steps to increase the chance they do not catch the disease. Properly cleaning and covering wounds is important for people battling an open wound. Effectively treating athletes foot or eczema if they were the cause for the initial infection will decrease the chance of the infection occurring again. People with diabetes should pay attention to maintaining good foot hygiene. It is also important to follow up with doctors to make sure the disease has not come back or spread. About one-third of people who have had erysipelas will be infected again within three years. Rigorous antibiotics may be needed in the case of recurrent bacterial skin infections. Notable cases
