Why Your Vitamin D Supplements Aren’t Effective

the truth about vitamin d supplements

So you found out that your vitamin D levels were low, and now, you’re taking vitamin D supplements. That’s great! It’s an important supplement to take when your body doesn’t get enough vitamin D. However, did you know that vitamin D needs magnesium in order to be metabolized? If you’ve been taking vitamin D for a while now but you’re not feeling the benefits, read on to find out how you can make the most out of your vitamin D supplements.

A review article published in the March issue of The Journal of the American Osteopathic Association stressed that many people don't know that taking vitamin D without adequate magnesium is not beneficial.

Magnesium is a mineral that activates hundreds of enzymes in our bodies related to crucial biological reactions, including the enzymes that play a role in vitamin D metabolism.

A national survey between 2005 and 2006 found that about half of all Americans do not consume adequate magnesium. The National Institute of Health, or NIH, recommends a magnesium intake of 400 to 420 milligrams per day for men, and 310 to 320 mg a day for women.

Interestingly enough, past research found that consuming magnesium can reduce the risk of vitamin D deficiency.

Good foods sources of magnesium include almonds, bananas, beans, broccoli, brown rice, cashews, egg yolk, fish oil, flaxseeds, green vegetables, milk, mushrooms, nuts, oatmeal, pumpkin seeds, sesame seeds, soybeans, sunflower seeds, sweet corn, tofu, and whole grains.

There are dangers is consuming too much magnesium – more than the daily recommended amount – such as diarrhea, nausea, and abdominal cramping. Extremely high intakes can lead to irregular heartbeat and cardiac arrest, according to the NIH. Before taking synthetic supplements, it is best to gradually increase food sources of magnesium in order to control the amount that is consumed at one time.

This is yet another example of how good health and longevity are never found in one nutrient alone. They’re found in a delicate balance of many nutrients that are best consumed in whole food form. So, if you find that your vitamin D supplements aren’t working for you, talk to your doctor and start introducing healthy foods that are rich in magnesium to your balanced diet!

I did not realize that! That is why getting nutrients in food vs a capsule is always best.
