Magnesium and Testosterone

Boosting testosterone is important for muscle growth – but what good is it if your body access it properly? That’s where magnesium comes in.

Over 60% of the testosterone in your body is used up by a protein called Sex Hormone Binding Globulin (SHBG). This protein binds to the male hormone in the blood stream and strips it of its anabolic potency. This stops the hormone having any value for muscle growth, and renders it useless to your gains.

Any available Testosterone is known as ‘free testosterone’, and the more you have of it the better, and supplementing this mineral is a great way to get you there.

But that’s not all it does. Regular supplementation of this trace mineral offers multiple benefits which support both body and mind, such as:

  • Increases Free Testosterone – Makes more testosterone accessible
  • Enhances Mood and Motivation– Fights depression and anxiety
  • Reduces Blood Pressure – Better overall circulation
  • Supports Muscles – Prevents against soreness, fatigue and cramps
  • Lowers Insulin Levels – Allows for more testosterone production

It is one of the main minerals you need for living both a happy and healthy life. If you’re constant sore or fatigued after training – this nutrient may be one of the key minerals your body is missing.

Why you should be supplementing Magnesium

After Vitamin D, Magnesium is the second most common nutrient that people don’t get enough of it developed countries. According to the World Health Organisation, 75% of Americans fail to meet their recommended intake of this mineral on a daily basis.

Foods like pumpkin seeds, bananas and leafy greens like spinach are rich in magnesium, however it can be difficult to consume enough of them to meet your daily requirements. A medium sized banana for example on contains 8% of your daily magnesium requirements.

The benefits of supplementing Magnesium

Taking in additional amounts of magnesium has numerous benefits when it comes to your body, and your mind. Numerous studies vouch for the mineral’s effectiveness, here’s just a handful of them, and why you should add it to your stack.

A study that supplementing magnesium with both sedentary and active subjects for a 4 week period saw testosterone levels have a significant increase. Both free and total testosterone levels rose with regular intake [1], which allows for testosterone levels to increase far quicker.

The mineral can also help with mood, with studies showing oral supplementation of magnesium can help fight depression in some cases [2].

Whereas a 6 month course of supplementing Magnesium has been seen to help lower blood glucose and insulin levels in individuals [3]. This is essential to testosterone levels, as high insulin levels can interfere with T-production and dramatically lower the body’s testosterone levels.

Muscles also benefit from an increase in magnesium. Triathlon athletes who supplemented the mineral for 4 weeks, noticed significant improvements in the their performance times, with increases in both their muscle oxygenation and aerobic exercise capacities [4].magnesium-testosterone
