Why You Should Take Vitamin D3 With Magnesium

If you’re curious about how you can take vegan vitamin D and magnesium together to optimize your health, then you’ve come to the right place. We have everything you need to know about this dynamic duo, from the health benefits to how much of each our bodies need.

Vegan Vitamin D3 and magnesium should be taken together to ensure maximum absorption of vitamin D. Magnesium activates vitamin D, allowing it to support bone growth and development.

So if you’re ready to maximize the effects of your vitamins, keep reading. We’ll explain the role that magnesium plays in supporting this vital nutrient and our overall health. 

What is vitamin D3? 

Vitamin D3 is the active form of fat-soluble vitamin D, and it can be taken as a dietary supplement to ensure adequate vitamin D levels in the body.

We must be consuming enough of this nutrient to experience its many health benefits, some of which include:

  • Maintenance of solid bones
  • Dental health
  • Cardiovascular health
  • Immune function

Because vitamin D is an essential nutrient, our bodies can’t produce it independently. This means we need to consume it from outside sources, like our diet or sun exposure.

Food sources rich in vitamin D include:

  • Dairy products
  • Egg yolk
  • Fatty fish (tuna, mackerel, salmon)
  • Codfish oil
  • Sardines
  • Beef liver

However, those not consuming the sunshine vitamin from these sources may need to turn to vitamin D supplementation to fill this nutrient gap.

What is magnesium?

Magnesium is an essential mineral that our bodies need to function correctly, as magnesium plays a role in the following functions:

  • Maintaining strong bones
  • Regulating blood pressure
  • Reducing the risk of cardiovascular disease
  • Supporting brain and nerve function

We can increase our levels of this nutrient by getting more magnesium from food sources, some of which include:

  • Whole grains
  • Dark, leafy green vegetables
  • Legumes
  • Nuts and seeds
  • Avocado

However, to support proper magnesium intake, some of us may need to take a dietary supplement containing the amounts of magnesium necessary for our health.

Why take vitamin D and magnesium together?

Vitamin D and magnesium supplementation often go hand in hand, as these two nutrients are closely interlinked in terms of function.

Studies have shown that magnesium assists in the activation of vitamin D, which means we need an adequate intake of this nutrient to ensure bone and cardiovascular health.

If we have low magnesium levels, then our bodies are unable to process vitamin D, and we have an increased risk of developing a vitamin D deficiency.

Vitamin D deficiency side effects

Those of us deficient in vitamin D may experience the following side effects:

  • Fatigue
  • Depression
  • Loss of bones
  • Increase in bone fractures
  • Osteoporosis
  • Bone pain
  • High blood pressure
  • Cardiovascular issues

We can help to avoid vitamin D deficiency by adding vitamin D supplements to our diet. Luckily, FuelOrganics offers a high-quality vegan vitamin D3 supplement to support a healthy heart and bones.

Magnesium deficiency side effects

We know that a magnesium deficiency can cause low vitamin D levels, but it's important we also know the warning signs of magnesium deficiency.

Symptoms of magnesium deficiency include:

  • Fatigue
  • Mental health issues
  • Nausea and vomiting
  • Loss of appetite
  • Muscle cramps
  • Numbness and tingling
  • Osteoporosis
  • High blood pressure
  • Irregular heartbeat

But how do we know exactly how much magnesium we need in our diet to avoid these side effects?
