Therefore, conditions that affect the gut and digestion, like celiac disease, chronic pancreatitis, Crohn's disease, and cystic fibrosis, can reduce vitamin D absorption.
In spring and summer, 25 percent of the body (the hands, face, neck and arms) is exposed to the sun, and in these seasons, about 8 to 10 minutes of sun exposure at noon produces the recommended amount of vitamin D. In the winter, only 10 percent of the body is exposed, and nearly 2 hours of sun exposure at noon is ...
Generally, it takes a few weeks of taking daily vitamin D supplements for vitamin D levels in the body to rise. Each 1,000 IU of vitamin D3 taken daily is expected to raise blood levels of 25(OH)D by 10 ng/ml after a few weeks.
Orange. There are limited Vitamin D fruits. Around 75% of people worldwide are either allergic to dairy products or lactose intolerant; some are vegan. So, orange or orange juice is the best option with vitamin D and other nutrients such as calcium.
Many fruits and vegetables contain a special type of vitamin D known as ergocalciferol, or vitamin D2. The highest value of vitamin D2 is found in the trendy, yet incredibly tasty avocado.
Research has found that an average serving of 2 eggs contains 8.2mcg of vitamin D, a substantial portion of the recommended dietary intake of vitamin D [2], making them a great addition to the diet to support the intake of adequate levels of this vital vitamin.

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.
"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.
“For better absorption of vitamin D, you must include vitamin K, magnesium, and zinc in your diet. They speed up the absorption procedure and reduce your likelihood of being vitamin D deficient,” she suggests.
Muscle weakness due to vitamin D deficiency is predominantly of the proximal muscle groups and is manifested by a feeling of heaviness in the legs, tiring easily, and difficulty in mounting stairs and rising from a chair; the deficiency is reversible with supplementation (15–18).
[9,10] Low vitamin D leads to bone abnormalities (e.g., osteomalacia, osteopenia, and osteoporosis) and worsens muscle strength. [11] In otherwise healthy individuals, fatigue can be a manifestation of low vitamin D levels and its impact on reduced maximum functioning of skeletal muscles via vitamin D receptors.
Some side effects of taking too much vitamin D include weakness, dry mouth, nausea, vomiting, and others. Taking vitamin D for long periods of time in doses higher than 4000 IU (100 mcg) daily is possibly unsafe and may cause very high levels of calcium in the blood.
