Can Zinc Help with Leg Cramps? Let’s Find Out
Leg cramps are a common problem that can occur due to various reasons such as overuse, dehydration, muscle fatigue, or an underlying medical condition. It can cause sudden and involuntary contractions or spasms in the muscles of the leg, usually in the calf or foot area, which can be extremely painful and debilitating. There are various remedies available to prevent or ease leg cramps, and one such remedy that has been gaining popularity is zinc. In this article, we will explore whether zinc can help with leg cramps or not and how it works for the same.
What is Zinc?
Zinc is a vital mineral required by the body for various biological functions such as cell growth and division, wound healing, immune system regulation, DNA synthesis, and protein synthesis. It is found in several food sources such as oysters, red meat, poultry, beans, nuts, whole grains, and certain fortified foods. The recommended dietary allowance (RDA) for Zinc varies depending on age, gender, and other factors.
How Does Zinc Help with Leg Cramps?
While there is limited scientific research to conclusively prove that zinc can help with leg cramps, some studies suggest that it might be beneficial. Zinc has been shown to improve muscle strength, endurance, and might contribute to reducing muscle cramps by regulating intra-cellular calcium levels.
Zinc has a critical role in maintaining neuro-muscular function and may help in proper transmission of the nerve impulses in the muscles. A lack of adequate zinc levels in the body has also been linked to muscle cramps, fatigue, and weakness. Zinc might also help in muscle recovery after intense physical activities and delay the onset of muscle fatigue, which can cause leg cramps.
How Much Zinc is Recommended for Leg Cramps?
While it is essential to maintain adequate zinc levels in the body, excessive amounts can be harmful, leading to various health issues. The RDA for zinc varies from 2-13 mg per day, depending on age, gender, pregnancy or lactation status, and other factors. As per the National Institutes of Health (NIH), adults should not consume more than 40 mg of zinc per day, including the intake from dietary and supplemental sources.
However, there is no specific recommendation for the amount of zinc to prevent or treat leg cramps. Some studies suggest that taking 15-30 mg of zinc daily might be beneficial for overall muscle health, but it is best to consult a healthcare professional before taking zinc supplements for leg cramps.
