What Is Vitamin D?
Vitamin D is a fat-soluble nutrient essential for bone, muscle, and immune health. Your body produces it when exposed to sunlight, yet many people in the UK experience deficiency—especially during the darker months.
Two key forms exist:
Vitamin D2 (ergocalciferol): plant-derived, used in fortified foods.
Vitamin D3 (cholecalciferol): animal-derived, more bioavailable and effective at raising blood levels.
When sunlight and diet aren’t enough, supplementation helps maintain optimal levels year-round.

Why Is Vitamin D Important?
Vitamin D contributes to multiple essential functions:
Bone and muscle health – aids calcium and phosphate absorption.
Immune support – helps regulate immune response and reduce infection risk.
Mood and energy – low levels are linked with fatigue and seasonal low mood.
Cardiovascular and metabolic balance – associated with heart and metabolic wellness.
To further support immunity and recovery, consider pairing Vitamin D with Zinc.
Public Health England reports that 1 in 6 UK adults have low Vitamin D levels in winter, making supplementation an important daily habit.
How to Use Vitamin D Supplements
Take one tablet, capsule, or spray daily with food for best absorption.
The NHS recommends 10 µg (400 IU) per day for adults.
Individuals with deficiency or limited sun exposure may benefit from higher doses under medical supervision.
As a fat-soluble vitamin, take Vitamin D with a meal containing healthy fats for optimal absorption.

Muscle weakness in body parts near the trunk of the body, such as the upper arms or thighs.
Waddling while walking, due to muscle weakness in the hips or legs.
How can I raise my vitamin D level quickly?
To raise your vitamin D levels quickly, get sun exposure, take vitamin D3 supplements, and eat vitamin D-rich foods like fatty fish, eggs, and fortified dairy.
Can vitamin D deficiency cause multiple sclerosis?
Vitamin D deficiency has been linked to an increased risk of developing multiple sclerosis (MS), a chronic autoimmune condition that affects the central nervous system. While it is not a direct cause, research suggests that low levels of vitamin D may influence the immune system in ways that make individuals more susceptible to MS. Populations living in areas with limited sunlight exposure — a key source of vitamin D — tend to have higher rates of MS, further supporting this association. Maintaining adequate vitamin D levels may help reduce the risk, especially in those with a family history or genetic predisposition.
What foods have vitamin D?
Some foods naturally contain vitamin D, while others are fortified to help people meet their daily requirements. Fatty fish such as salmon, mackerel, and sardines are among the best natural sources. Cod liver oil is also rich in vitamin D. Egg yolks and liver contain small amounts, as do fortified foods like cow’s milk, plant-based milks (such as soy and almond), breakfast cereals, and margarine. However, diet alone often isn’t enough to meet recommended levels, especially during the winter months, which is why supplementation is common.
Can lack of vitamin D cause heel pain?
Inadequate vitamin D can lead to osteoporosis, increased risk of falls, fractures and bone and muscle pain. In the foot and ankle, stress fractures of the metatarsal bones and ankle may be seen in those with vitamin D deficiency, as well as generalized foot pain.
Does low vitamin D cause weight gain?
There is limited evidence that low vitamin D levels directly cause weight gain. However, vitamin D deficiency and obesity are both risk factors for chronic diseases.
Can vitamin D stop dandruff?
Vitamin D is not a direct cure for dandruff, but it can support overall scalp health. A deficiency in vitamin D may contribute to dry skin and inflammation, which are factors that can worsen dandruff symptoms. Vitamin D plays a role in skin cell growth and immune function, and some studies suggest that low levels may be associated with scalp conditions like seborrheic dermatitis. While using topical treatments remains the most effective way to manage dandruff, ensuring your vitamin D levels are sufficient may help support healthier skin and reduce flaking over time.
