Vitamin D, commonly known as the ‘sunshine vitamin’, is a vital nutrient that plays a significant role in our overall health. Insufficient levels can leave individuals feeling depleted.

With the arrival of spring and the extension of daylight hours, many people experience an uplift in their mood, particularly on sunny days. However, this can lead some to make a significant error, as highlighted by a dietitian who described this misunderstanding as one of the most common.
As the days brighten, individuals tend to stop taking their winter supplements, a decision that could be unwise. When it comes to vitamin D, ceasing supplementation too early can leave your body lacking essential nutrients.
Karine Patel from Dietitian Fit emphasizes that sunshine alone may not fulfill your body’s vitamin D requirements at this time of year. She explains why many people tend to stop their vitamin D intake prematurely, the common misconception surrounding the ideal cut-off date, and the signs indicating that your body could still require this crucial nutrient.
The Ongoing Importance of Vitamin D in Spring
Patel states: “Vitamin D is essential for maintaining strong bones, supporting immune health, regulating mood, and ensuring muscle function. Nevertheless, many people remain deficient throughout the year.
“In the UK, during the winter months, we do not receive adequate UVB exposure, preventing sufficient vitamin D synthesis through sunlight alone. As spring arrives, many individuals may unknowingly still be low or deficient. Even as the weather improves, early spring sunlight is often insufficient to stimulate adequate vitamin D production in the skin.
“People tend to assume that brighter days will naturally boost their vitamin D levels. However, UV levels during March and early April are still low, especially for those who spend most of their time indoors.”
The Common Misconception About Supplement Cessation
Karine notes: “One of the biggest misconceptions is when it’s appropriate to stop taking supplements. Many individuals discontinue their vitamin D intake as soon as the clocks change or at the beginning of March. For most, April is still too early.
“A more accurate cut-off point would be late April to early May, when UVB rays begin to increase sufficiently for the body to synthesize adequate vitamin D, provided you are regularly exposed to midday sun. Stopping too soon could prolong a period of low vitamin D levels, adversely affecting immunity, energy levels, and overall wellness.”
Who Should Continue Supplementation for Longer?
While some individuals may discontinue supplementation by late spring, certain groups are advised to extend their intake, and in some cases, maintain it year-round. Here are those who should be particularly cautious about stopping too early:
- Individuals who predominantly stay indoors, such as remote and office workers.
- People who cover their skin outdoors for personal or cultural reasons.
- Older adults whose skin produces vitamin D less efficiently.
- Individuals with darker skin tones, as higher melanin levels reduce the skin’s ability to produce vitamin D from sunlight.
- Those residing in northern regions of the UK where sunlight is less intense.
Karine advises: “For these groups, depending solely on sunlight is not advisable, even during spring and summer, so continuing supplementation beyond April may be necessary.”
Is Food Sufficient for Vitamin D Intake?
It is generally challenging to meet vitamin D needs through diet alone. Karine elaborates: “While certain foods, like egg yolks, fatty fish, and fortified items, can provide some vitamin D, the quantities are often too low to fulfill daily requirements.
“Consequently, achieving adequate vitamin D intake solely through food is difficult, which is why supplementation is frequently recommended, especially in countries like the UK.”
Signs That You Might Need More Vitamin D
Many individuals are unaware of their vitamin D deficiency, as symptoms may be subtle or mistaken for general fatigue. Karine suggests looking out for:
- An increase in illness
- Persistent fatigue or low energy
- Muscle pain or weakness
- Feelings of low mood or being ‘flat’
- Joint or bone discomfort
Karine adds: “Often, these symptoms are dismissed as seasonal fatigue or stress, but they can indicate that your vitamin D levels are not where they should be.”
When Is It Safe to Stop Taking Vitamin D?
So, when can you reasonably consider discontinuing vitamin D supplementation? Karine clarifies: “For most individuals in the UK, the safest time to think about stopping your supplements is from late April to early May.
“However, this varies depending on your lifestyle and whether you are regularly getting midday sunlight exposure on your skin. If that isn’t occurring consistently, it’s advisable to continue supplementation for a while longer.”
