Introduction
 Magnesium (Mg) is one of the most important micronutrients, playing a supportive role in muscle recovery, sleep, and stress reduction, just to name a few. Outside of iron, calcium, and potassium and vitamin D, no micronutrient is required to be present on a nutrition label. Which is a shame, because most people should be paying more attention to their magnesium intake.


 Along with sodium and potassium, magnesium is a critical electrolyte for your body. Often lost during sweating, magnesium plays a vital role in forming the structures of proteins, mitochondria, and bones in your body. Magnesium has been shown to not only aid in recovery by reducing muscle cramps and soreness, but it can also lead to improved exercise performance.


 Magnesium is crucial for muscle and mind relaxation, ATP production, gene maintenance, nervous system regulation, formation of proteins, and much more. This mineral is a cofactor in hundreds of different biochemical reactions in your body, and is found in ample amounts in nuts, seeds, and beans.

Why Do You Need Magnesium?
 It's estimated that 75% of American adults are magnesium deficient. This is largely in part due to our ultra-processed diet, which is entirely void of most micronutrients, magnesium included. Most people don't realize they're deficient in this crucial mineral.


 Optimal magnesium consumption is linked with better sleep, improved mood, protection against heart disease and Type 2 Diabetes, lower risk of cancer, lower blood pressure and cortisol, and improved mood. Quite literally, a magnesium supplement is a "chill pill"; magnesium supplementation has been shown to significantly combat depression and anxiety. Magnesium supplements include powders, pills, and liquid droppers.


 Consuming optimal levels of magnesium, either through food or supplementation, is vital to your health. Magnesium plays a role in protein synthesis, creation of DNA and RNA, muscle recovery and relaxation, preserving nerve and brain cells, and regulating blood sugar. These are all slowed down with alcohol and caffeine consumption, as magnesium is not able to perform its job properly.

Wrapping it Up
 Magnesium is an essential mineral and electrolyte that is rich in nuts, seeds, legumes, and dark leafy greans. It's critical for bone and muscle health and function, often aiding in recovery and preventing soreness and fatigue. Magnesium is also crucial in the production of ATP, aiding in converting food into energy for metabolism regulation. The RDA of magnesium is 400 mg for men and 310 for women, and symptoms of deficiency include muscle cramps, irritability, osteoporosis, and muscle cramps.
