As we enter into the summer months we will all have more opportunities to get more sunlight and thus more vitamin D. Yet many regularly still take vitamin D supplements if they are unable to get daily sunshine.
Another factor to consider is magnesium status. People who take vitamin D supplements but who have low magnesium levels may not be getting adequate active vitamin D.
Without enough magnesium, vitamin D stores in the body remain inactive, and taking vitamin D supplements when magnesium is low can raise circulating calcium and phosphate levels, possibly leading to blood vessel calcification.
When magnesium levels are good, the body needs less vitamin D to reach adequate D levels, and inactive vitamin D stores become active. Also, when magnesium and vitamin D levels are optimal, chances for bone thinning (osteoporosis) and bone fracture are less. While calcium recommendations are set in place to address this, it’s a bit more complicated than anyone one mineral; that is why it is important to address any nutrient deficiencies – thus the need to ensure adequate magnesium intake.
Common sources of magnesium include:
- Seeds (squash and pumpkin seeds)
- Lima beans
- Brown rice
- Dark chocolate
