The easiest vitamin D to absorb is generally Vitamin D3 (cholecalciferol), especially when taken with a meal containing healthy fats like avocado, nuts, or fatty fish, as it's fat-soluble and fat enhances its uptake into the bloodstream. While D2 and D3 are both absorbed well, D3 often raises blood levels higher and for longer, making it preferred in supplements, notes National Institutes of Health (NIH).
Medications used to treat high blood pressure are generally safe to take with vitamin D supplements. Examples include: Angiotensin-converting enzyme (ACE) inhibitors, such as lisinopril (Zestril, Qbrelis) Angiotensin II receptor blockers (ARBs), such as losartan (Cozaar)
RCOG Scientific Impact Paper recommends the treatment of vitamin D-deficient pregnant women with either colecalciferol 20,000IU/week or ergocalciferol 10,000IU twice a week for 4–6 weeks.
What helps Vitamin D absorption? Keep in mind that Vitamin D is a fat-soluble vitamin, which means it's best absorbed in the bloodstream in the presence of dietary fat. So, if you're taking your Vitamin D supplement at breakfast, lunch, or dinner, you can pair it with a food containing healthy fat.
Magnesium plays an important role in liver and kidney function, and it's essential for the absorption of vitamin D. The enzymes that are responsible for metabolizing vitamin D all seem to require magnesium. 1 If your magnesium level is too low, your body cannot activate or process vitamin D.
You can quickly raise your vitamin D levels by taking a vitamin D supplement (often the fastest method), eating vitamin D–rich or fortified foods, and getting safe sunlight exposure. Supplements, especially vitamin D3, generally work fastest, but always follow medical guidance for optimal results and safety.
Two forms of vitamin D are available in supplements: vitamin D3 and vitamin D2. Both can help correct vitamin D deficiency, but most doctors recommend D3 because it is slightly more active and therefore slightly more effective. Vitamin D3 is naturally produced by animals, including humans. Vitamin D2 is the plant form.
However, when the researchers compared pregnancy outcomes across a wider range of vitamin D concentrations, they found that pregnant women with first trimester vitamin D concentrations lower than 40 nmol/L were four times more likely to experience a preterm birth compared to women with vitamin D concentrations more ...
The results of this meta-analysis indicate that supplementation with vitamin D does not lower blood pressure in the general population. On the basis of this finding, we do not recommend using vitamin D supplementation to prevent hypertension.
Four Common Mistakes When Taking Vitamin D
Treatment with losartan causes an increase in urinary Zn excretion and induces Zn deficiency in patients with hypertension. The addition of hydrochlorothiazide has an additive effect. Magnesium and nitric oxide metabolism are not affected by either treatment.
Softgels can be better than capsules when it comes to Vitamin D supplements. They often contain Vitamin D in an oil, which improves absorption since D3 is fat-soluble. That means you need fat in your system to absorb it well, and softgels help with that — for example, Vitamin D3 with MCT oil, olive oil, soy oil, etc.
Dark, leafy greens like spinach are often good sources of nutrients like vitamin K, calcium and magnesium, all of which pair well with vitamin D.
A two-year study of osteoarthritis patients found that 50,000 IU per month is safe. When buying a supplement, look for vitamin D3 (cholecalciferol) – the same form the body makes from sunlight. It is better absorbed and more effective than vitamin D2 (ergocalciferol).
Even though D3 seems to be a better option for supplementation, you might be wondering why healthcare professionals prescribe vitamin D2 instead. This is usually based on which form is available in the dosage someone needs. For example, high-dose vitamin D2 is the only form that's available by prescription.
10 Unexpected Signs of a Vitamin D Deficiency
Medical conditions that can cause vitamin D deficiency include: Cystic fibrosis, Crohn's disease and celiac disease: These conditions can prevent your intestines from adequately absorbing enough vitamin D through supplements, especially if the condition is untreated.
Vitamin D is the sunshine vitamin that has been produced on this earth for more than 500 million years. During exposure to sunlight 7-dehydrocholesterol in the skin absorbs UV B radiation and is converted to previtamin D3 which in turn isomerizes into vitamin D3.
