What is Swanson Ultra Magtein Magnesium L-Threonate?

Magnesium is essential to your heart, teeth, bones, kidneys and muscles (to name but a few!), it sounds a little trite to call it an essential mineral. If it weren’t for the fact that the term ‘essential mineral’ actually refers to any nutrient that we cannot synthesise inside our bodies. In other words, we have to get it from our diet.

Given that Magnesium is widely available in whole grains, nuts and green leafy vegetables, it doesn’t sound like it should be too hard to get our fill. Unfortunately, recent research points to the contrary. Increasing quantities of sugar and caffeine in our diets are actually inhibiting our body’s ability to absorb Magnesium properly from our diets.

Which is why, if we choose to supplement our bodies with Magnesium, the bioavailability of that supplement is so important.

  • Roughly half of the US population is Magnesium deficient.
  • The RDA is between 350-400 mg per day.
  • Magnesium is normally found in whole grains, beans, nuts and green leafy vegetables.

There have been a number of different Magnesium supplements in the market in recent years and each boasts different ways in which they can help you better absorb this vital mineral. However, until now, none have been able to boast the incredible technology behind Swanson Ultra Magtein Magnesium L-Threonate.

Technology created and patented by a group of scientists from MIT, one of whom is a Nobel Laureate.

What is Swanson Ultra Magtein Magnesium L-Threonate used for?

Magnesium plays a number of roles in your body, most of which are based on the mineral’s ability to activate enzymes that contribute to energy production. It also helps to regulate levels of other vital nutrients in your body such as copper, calcium, potassium, zinc and vitamin D.

What Swanson Ultra Magtein Magnesium L-Threonate really focuses on though, is Magnesium’s effect on the mind.

As we grow older, our brains naturally degenerate. Traditional cognitive support has involved attempting to stimulate the neurons to promote peak brain function. Sadly, over time, this can have an equally negative effect, burning us out.

Swanson Ultra Magtein Magnesium L-Threonate works by nourishing the brain to help hold those neurons in a relaxed state of readiness. This process further facilitates the free exchange of those electrical impulses which transfer information in our brains.

  • Improves memory function
  • Without burning out the brain’s neurons
  • Can help to ease the effects of ageing on the mind
  • Only Magnesium supplement is capable of crossing the blood-brain barrier to promote optimum levels within the brain

What is the recommended dosage of Swanson Ultra Magtein Magnesium L-Threonate?

To be used as a dietary supplement. Take one vegetable capsule in the morning and then two in the evening with a glass of water.
