Vitamin D and Energy: Could You Still Be Low in Spring?

As the days get longer and brighter, many of us expect our energy levels to improve. Yet it’s not uncommon to still feel tired, flat or lacking motivation well into spring. One often overlooked factor is vitamin D.

Vitamin D plays a central role in overall wellbeing. It contributes to the maintenance of normal bones, supports normal muscle function and plays an important role in immune health. It has also been linked to mood and general vitality, meaning that when levels are low, this can subtly affect how we feel day to day.

Why Levels Can Remain Low in Spring

In the UK, vitamin D levels often decline over the winter months, when sunlight is not strong enough to support meaningful production in the skin. By the time spring arrives, many people are starting from a low baseline. This is reflected in wider population trends, with low vitamin D levels remaining common following the winter months.

Even with brighter days, restoring levels is not always straightforward. Sunlight is the body’s natural source of vitamin D, but in practice, achieving sufficient exposure can be challenging. Time spent indoors, consistent use of SPF, clothing coverage and individual differences in skin type all influence how much vitamin D is produced. As a result, low levels can persist well into spring and, for some, throughout the year.

Signs your levels may be low

• Frequent illness or reduced resilience
• Ongoing fatigue or low energy
• Muscle weakness or aches
• Low mood
• Reduced motivation

These symptoms can often be explained by a number of factors, but they can be a useful prompt to consider your vitamin D levels.

Vitamin D and Energy

Vitamin D is not a stimulant, but it supports several systems that underpin how we feel. Low levels have been associated with fatigue and reduced physical performance, both of which can contribute to a sense of low energy.

Supporting your levels

Sunlight

Sunlight remains the most natural way to support vitamin D production. However, for many people, consistent and sufficient exposure can be difficult to achieve in day-to-day life, meaning levels are not always fully restored through sunlight alone.

Diet

Vitamin D is found in foods such as oily fish and eggs, but intake is typically low and unlikely to meet requirements alone.

Supplementation

Supplementation is a practical way to maintain adequate vitamin D levels throughout the year. You can explore a range of options in our vitamin D collection, including capsules, sprays and liquids.

A new addition to our range is Meteron Labs Liposomal Vitamin D3 & K2, which I’m particularly pleased to see included. Using liposomal delivery technology, it supports efficient absorption, making it a highly bioavailable and easy-to-take option. The liquid format has a pleasant cherry and vanilla flavour and comes with a pipette for simple, accurate dosing.

Testing Your Levels

If you’re unsure where your levels stand, testing can be a helpful starting point. The W-Wellness Vitamin D Test offers a convenient way to check your vitamin D status from home, providing a quick and practical way to understand your levels.

The results can help indicate whether your levels are low and guide your next steps, including whether a higher initial intake may be beneficial or what dose may be appropriate to maintain healthy levels over time.

A Simple Check-In

Spring is a natural point to reassess your energy and overall wellbeing. If you’re still feeling low in energy despite improvements in light and routine, vitamin D is one factor worth considering.

Supporting your levels through a combination of sunlight, nutrition and, where appropriate, supplementation can help create a stronger foundation for overall health and energy as the seasons change.
