Best vitamin D supplements to boost your health and mood

If you are on the hunt for the best vitamin D supplement, then you're off to a good start. Vitamin D, frequently known as the 'sunshine vitamin', is central to maintaining good health, regardless of age or sex. This powerful nutrient is involved in just about everything from strengthening bone density to boosting immune function - it's no wonder that vitamin D is often at the top of the list when it comes to the best supplements for overall wellbeing.

Strikingly, despite its vast health benefits, many individuals are vitamin D deficient. According to Vitall's UK health statistics in 2023, approximately 20 per cent of the population in the UK has a vitamin D deficiency, and 60 per cent of the population is considered as having insufficient levels of vitamin D. This could be due to a combination of factors, including limited exposure to sunlight, certain dietary restrictions, and in some cases, genetic factors.

However, it is good to note that vitamin D3 is the form of vitamin D derived from animal sources and is more potent than its plant-based counterpart. However, vitamin D3 can also be derived from lichen, a vegan-friendly source.

Buyer's guide to vitamin D

Our modern lifestyles often involve extended indoor periods, and, let's be honest, the weather isn't always on our side to supply that much-needed sunshine for vitamin D.

We spoke to Kate Booker, nutritionist at Nutrition Geeks, to determine the importance of vitamin D and how to choose the best supplement for you. Although remember, a balanced diet, rich in various vitamins and minerals, is the foundation of good health, so consider these supplements as your health-supporting assistants, not substitutes. There are many foods that contain vitamin D that you could add to your diet too.

What does vitamin D do for the body?

The popularity of vitamin D supplements is no fad - as this vital vitamin is central to the healthy functioning of our body. Kate tells us that vitamin D benefits bone health supports bone density (along with vitamin K2), and helps to protect against osteoporosis.

"Low vitamin D levels are associated with bone loss and fractures," says Kate. "Vitamin D can improve muscle function and balance, reducing the risk of falling. Vitamin D also supports immune function, protecting against infections and allergies. It’s also beneficial to gut health."

She also says it is also worth noting that magnesium is required to make vitamin D, so it’s important to include this mineral in your diet. "Magnesium is found in green leafy vegetables, cacao, bone broths and sardines," suggests Kate. She also says it can also be absorbed through the skin via Epsom salts in the bath. "Vitamin K2 is an important vitamin for bone density. K2 can be found in fermented and probiotic foods."

In our roundup above, we provide you with suggestions on supplements that include the synergy of D3 and K2. Our top recommendations are Viridian D3 & K2 90 Capsules and Nutri Advanced's Vitamin D3 with K2 Liquid Drops.

Why is it important to supplement vitamin D?

Like we get a lot of vitamin C from foods, it's not as easy for vitamin D. "We can make vitamin D from the sun from March to October in the UK," Kate tells us. "Your genetics and skin tone will dictate how well you can make vitamin D from the sun; if you aren’t getting enough mid-day sun on your skin, then it could be beneficial to boost your intake through supplements. A good vitamin D supplement contains D3, which raises levels higher and for longer than D2."

What source of vitamin D is suitable for vegans?

In this article, we touch on what sources of vitamin D are suitable for plant-based diets as frequently D3 is sourced from Cholecalciferol - which is made from sheep's wool. We asked Kate what the difference is between D2 and D3 and what was the most appropriate form of vitamin D for vegan lifestyles.

"D2 is a plant source of vitamin D found in mushrooms. D3 is the animal source, found in mackerel, wild-caught salmon, cod liver oil and oily fish," says Kate. "D2 is less than one-third as potent as cholecalciferol, so D3 is a better supplement option. D3 supplements also stay in circulation longer."

So it is best to go for a supplement with vitamin D3 if you are vegan but check if the source was derived from lichen - which is a vegan-friendly source. If you are also looking for supplements to complement a vegan lifestyle, it is a good idea to look into the best B12 supplements as well to bridge the nutrient gaps.

How much vitamin D should you take for menopause?

"This depends on your blood levels; checking your blood levels of vitamin D can ensure you are taking the correct amount. Ideally, your levels should be in the optimal range, which is 75-125 nmol/L. For most people, a dose of around 1000iu will be safe to take." Many of the best supplements for perimenopause and menopause will factor this into their formulas too.
