Now there’s an all-in-one test for measuring your vitamin D, magnesium and omega-3 levels.

Magnesium is essential for your brain and bone health, blood glucose control, DNA and genetic material, blood pressure, detoxification processes and for activating vitamin D in your body. It’s believed that about 80% of Americans don’t get enough. And as you age, your body becomes less efficient at absorbing magnesium.

Low levels of magnesium are linked to heart and brain issues, migraines, blood pressure and blood sugar concerns, and insulin resistance.

The Vitamin D, Magnesium & Omega-3 Test Kit measures magnesium in addition to vitamin D and omega-3 levels in one simple, at-home blood test.

Because only 1% of the magnesium in your body is actually found in your bloodstream, a regular serum magnesium test doesn’t give you an accurate measurement. Instead, the Vitamin D, Magnesium & Omega-3 Test measures the amount of magnesium in your red blood cells with the more sensitive RBC blood test.

When your body becomes deficient in magnesium, it pulls the magnesium stored in your red blood cells and deposits it into the serum of your blood. Therefore, a standard serum magnesium blood test may show magnesium levels as normal even though the red blood cell’s stores of magnesium are depleted.

Want to take the Vitamin D, Magnesium & Omega-3 Test a step further and find out your blood levels of other important minerals, like selenium, zinc and copper, as well as your possible load of toxic heavy metals, like cadmium, lead and mercury? The Vitamin D, Magnesium & Omega-3 PLUS Elements Test KIT measures your levels of vitamin D and omega-3s along with these essential minerals and unwanted heavy metals.

Much like magnesium, selenium and zinc deficiencies are a widespread concern for people around the world. These important minerals are needed for cell health, immune function, normal healthy lipid levels and a healthy inflammatory response.

As far as what you don’t want in your body – cadmium, lead and mercury are three of the most potentially harmful metals that can be found in your blood. You’re exposed to them through the air, water, medicines, dental amalgams and certain foods.

When your body can’t remove these heavy metals through its normal detoxification processes, they can accumulate and impact your thinking and memory, behavior and organ function.
