Which are the best vitamin D supplements?
Vitamin D, or the “sunshine vitamin” as it’s commonly known, is a prohormone and fat-soluble vitamin.
When exposed to sunlight, our bodies produce vitamin D naturally, and we also acquire it from foods like salmon and eggs.
However, unless you’re getting consistent sun exposure or eating lots of the foods mentioned above, then it can be very difficult to get enough vitamin D in your bloodstream, which is why taking a vitamin D supplement can be very beneficial.
In this article, we’ve reviewed all the vitamin D supplements on the market and rounded up the best money can buy.
Here’s a list of the 10 best vitamin D supplements:

Frequently Asked Questions About Vitamin D Supplements
Q: What Is Vitamin D?
Vitamin D, or the “sunshine vitamin” as it’s commonly called, is a fat-soluble vitamin (prohormone) and nutrient produced in the human body and obtained through diet.
Despite being called a vitamin, vitamin D is a prohormone or a precursor of a hormone, which helps amplify the effect of existing hormones.
However, as the body produces vitamin D in your skin when exposed to sunlight, it’s generally referred to as a vitamin or nutrient.
Vitamin D is essential for optimal human health as it provides the body with several important functions.
Q: What Are The Benefits of Vitamin D?
Vitamin D has multiple benefits in the body that help keep us functioning properly as human beings.
It is essential for strong bones as it’s required for your body to properly absorb calcium, magnesium, and phosphate, which help strengthen bones and reduce the risk of bone degeneration or osteoporosis.
Vitamin D is also believed to help support immune, brain, and nervous system health, regulate insulin levels and support diabetes.
Although the body can create enough vitamin D to sustain itself, deficiencies can occur for various reasons, which is why supplementing with vitamin D can be extremely beneficial as a preventative measure.
Q: Does Vitamin D Have Any Side Effects?
Vitamin D is generally considered safe to supplement with when taken in recommended amounts.
Most people do not commonly experience side effects with Vitamin D, and it is well-tolerated overall.
However, some people might experience mild side effects like fatigue, nausea, and headaches, but generally, this is caused by taking too much vitamin D.
Other side effects include loss of appetite, dry mouth, vomiting, nausea, constipation, and diarrhea.
Although not 100% certain, taking large amounts of vitamin D for long periods may cause high calcium levels in the blood.
Always check with your doctor or healthcare provider before adding any supplement to your diet.
Q: How Do I Take Vitamin D Supplements?
The current recommended daily intake of vitamin D for children and adults up to 70 is 600 IU.
However, if you’re deficient in Vitamin D, your doctor will likely prescribe a much higher dose for around 6-12 weeks to bring your levels back to normal.
As vitamin D is fat-soluble, it’s best taken with food but does not need to be taken at any specific time of the day.
To air on the side of caution, we suggest halving the recommend serving size until you’ve assessed your tolerance and slowly work your way up to a whole serving over time.
If you are taking any over-the-counter medications or prescribed antibiotics, you should check with your doctor to see if they may interfere with vitamin D or cause any side effects.
Q: Which Vitamin D Supplement Should I Choose?
When choosing a vitamin D supplement, you should opt for one that has a good reputation, contains high-quality ingredients, and is tested and verified to ensure overall quality.
All of the vitamin D supplements in this roundup are manufactured by reputable brands with a proven track record in the supplement industry.
Choose one that’s as natural as possible, clear of artificial ingredients and preservatives, and contains the correct amount per serving according to your requirements.
Generally, vitamin D capsules and softgels are the most common form of the supplement, but liquid drops and chewable gummies are also just as good, so choose whichever form you prefer.
