A conventional food in the form of a sports drink which contains quinine for preventing muscle cramping in athletes who undertake strenuous physical activity. In one form, the sports drink is a water-based composition which includes quinine as a muscle cramping preventative, as well as suitable electrolytes, such as potassium, calcium, sodium, and one or more flavoring agents for palatability. The sports drink also includes magnesium and/or calcium to enhance the muscle cramping preventative effects of quinine. The sports drink may also include carbohydrates, vitamins, minerals, amino acids, and other nutrients as desired, and may have an acidic or substantially neutral pH. When consumed prior to, during, or after undertaking physical activity, the sports drink has been observed to be effective in preventing muscle cramping, or alleviating muscle cramping once it has occurred.
