Vit D is prone to degradation when exposed to heat, light, moisture, or oxygen during processing as well as storage. Thermal processing of foods such as boiling, pressure cooking, frying, steaming, baking and sterilization can significantly affect the final level of Vit D in food [21, 22] .
The health of your gut.
Therefore, conditions that affect the gut and digestion, like celiac disease, chronic pancreatitis, Crohn's disease, and cystic fibrosis, can reduce vitamin D absorption.
Vitamin D is fat-soluble and is stored in the body's fat tissue when ingested in large amounts. Vitamin D is destroyed by light and heat from cooking.
Another study found that 30 minutes of midday summer sun exposure in Oslo, Norway was equivalent to consuming 10,000–20,000 IU of vitamin D ( 8 ). The commonly recommended daily dose of vitamin D is 600 IU (15 mcg) ( 3 ).
In general, the two main causes of vitamin D deficiency are: Not getting enough vitamin D in your diet and/or through sunlight. Your body isn't properly absorbing or using vitamin D.
You don't absorb enough vitamin D from food (a malabsorption problem) You don't get enough exposure to sunlight. Your liver or kidneys cannot convert vitamin D to its active form in the body. You take medicines that interfere with your body's ability to convert or absorb vitamin D.
"Adequate levels of magnesium in the body are essential for the absorption and metabolism not only of vitamin D but of calcium as well," Dean states. "Magnesium converts vitamin D into its active form so that it can help calcium absorption.
Vitamin D is a fat-soluble vitamin, meaning that it does not dissolve in water and is absorbed best in your bloodstream when paired with high fat foods ( 1 ). For this reason, it's recommended to take vitamin D supplements with a meal to enhance absorption.
Magnesium assists in the activation of vitamin D, which helps regulate calcium and phosphate homeostasis to influence the growth and maintenance of bones. All of the enzymes that metabolize vitamin D seem to require magnesium, which acts as a cofactor in the enzymatic reactions in the liver and kidneys.
Vitamin D3 supplements are thought to raise vitamin D levels in the bloodstream in around 24 hours. However, it takes up to 7 days for this to be converted into the active form of vitamin D – which is what a blood test will pick up.
Yes! You can and should take magnesium and vitamin D together. In fact, the bioavailability of vitamin D largely relies on magnesium. Also, many nutrients wouldn't work efficiently without magnesium, further highlighting the importance of this mineral!
Consumption of vitamin D supplements without enough magnesium can lead to problems such as vascular calcification. Calcification happens when calcium builds up in body tissue, blood vessels, or organs and vascular calcification refers to build-up in the arteries and veins.
Magnesium can decrease the absorption and effectiveness of numerous medications, including some common antibiotics such as tetracycline (Achromycin, Sumycin), demeclocycline (Declomycin), doxycycline (Vibramycin), minocycline (Minocin), ciprofloxacin (Cipro), levofloxacin (Levaquin), moxifloxacin (Avelox) and ofloxacin ...
The use of chemicals, such as fluoride and chlorine, bind to magnesium, making the water supply low in the mineral, as well. Common substances — such as sugar and caffeine — deplete the body's magnesium levels.
One study of older adults with insomnia found that magnesium supplementation at a dose of 500 milligrams daily for eight weeks helped them fall asleep faster, stay asleep longer, reduced nighttime awakenings, and increased their levels of naturally circulating melatonin.
Magnesium and calcium/multivitamin
But if you do take magnesium, Erin Stokes, ND, recommends not taking it at the same time as your multivitamin, as it may interfere with the absorption of smaller minerals found in the multivitamin, like iron and zinc.
People with diabetes, intestinal disease, heart disease or kidney disease should not take magnesium before speaking with their health care provider. Overdose. Signs of a magnesium overdose can include nausea, diarrhea, low blood pressure, muscle weakness, and fatigue. At very high doses, magnesium can be fatal.
Studies in rats confirm that dietary magnesium depletion results in reduced bone mass. Although no such studies have been carried out in humans, research has associated poor magnesium intake with lower bone mineral density ( 11 , 12 ).
MAGNESIUM GLYCINATE – The Best Absorbed Form of Magnesium.
The researchers found that vitamin D did not affect the frequency or severity of muscle cramps despite vitamin D repletion. This same study also found no relationship between muscle cramps and dietary or serum magnesium or fluid intake.
Magnesium and zinc
All minerals and vitamins need the proper conditions for your body to absorb them properly. When taken together, magnesium and zinc have mutual benefits. Magnesium helps your body regulate its zinc levels, while zinc does the job of allowing it to absorb magnesium more effectively.
Oranges are one of the fruits rich in Vitamin D as its juice is fortified with calcium & vitamin D. This is one of the best sources of vitamin D for people who are lactose intolerant and cannot include milk & dairy products in their diet.
