Product FAQs
Product FAQs
Why should I take Vitamin D?
Vitamin D is essential for overall health, helping your body absorb calcium for strong bones and teeth, supporting immune function, and contributing to normal muscle function.
Who should take Vitamin D tablets?
Vitamin D tablets are especially useful for people who get limited sunlight, have a diet low in Vitamin D, or have higher needs, such as older adults or those with certain health conditions.
How does Vitamin D help with bones and teeth?
Vitamin D helps with bones and teeth by supporting the absorption of calcium and phosphorus, which are essential for strong, healthy bones and teeth. Adequate Vitamin D helps maintain bone density, supports normal growth and development.
How does Vitamin D help with energy levels?
Low Vitamin D levels have been linked to fatigue, so keeping your levels within the normal range can help you feel more energetic and active.
Will Vitamin D help with (SAD)?
Vitamin D may help support mood during periods of low sunlight, such as in seasonal affective disorder (SAD). Low Vitamin D levels have been linked to feelings of fatigue and low mood, so maintaining adequate levels can contribute to overall wellbeing. However, it is not a treatment for SAD.
Do I need to take more Vitamin D in autumn/winter months?
During the autumn and winter months, your body produces less Vitamin D from sunlight, so your requirements may increase.
What’s the difference between 1000iu and 3000iu?
The difference between 1000IU and 3000IU is the strength. 1000IU is a moderate daily dose for general maintenance, while 3000IU provides a higher dose for those with low levels or increased needs.
What shouldn’t I take with Vitamin D?
Vitamin D absorption can be affected by certain substances. Avoid taking it at the same time as high doses of calcium, magnesium, or iron, as these can compete for absorption. Very high doses of certain medications, like corticosteroids or weight-loss drugs, may also interfere with Vitamin D.

Buy Vitamin D3 (1000IU) Tablets
Vitamin D3 (cholecalciferol) - also known as the sunshine vitamin - is an essential vitamin. While some people can absorb it through direct sunlight and a healthy diet, a vitamin D food supplement means your body gets all the beneficial effects daily, even when the sun isn't shining.

The many benefits of Vitamin D3
Vitamin D3 (calciferol) is a powerful vitamin with numerous benefits for your mind and body. While the body can absorb it naturally through exposure to sunlight, any people find they don't get enough during the winter months.
Taking vitamin D food supplements supports your body, helping it function normally, delivering various health benefits, whatever the weather.
Healthy bones
Vitamin D2 contributes to the growth of normal bones, as it promotes the normal absorption of calcium, which results in normal teeth and bones.
Using the recommended dosage to ensure the maintenance of normal bones also works to prevent conditions like osteoporosis and rickets, as you can enhance bone density.
Mental wellbeing
While there's no conclusive evidence that Vitamin D3 can reduce the symptoms of mental health issues such as depression, some studies due highlight that it has a positive effect on people.
Research published by Neuroscience News shows that children who get enough vitamin D in childhood are less likely to struggle with anxiety and low moods later in life.
Immune system support
The immune system is complex, but Vitamin D3 contributes to its functioning. A daily dose of vitamin D can boost the positive effects of macrophages and monocytes and their pathogen-fighting mechanisms.
By ensuring the normal function of the immune system, you can reduce the risks of certain chronic diseases, including autoimmune conditions.
Muscle function
Studies from Harvard Health have revealed that low Vitamin D levels contribute to insufficient muscle strength. Normal muscle function is central to ensuring you can perform daily activities and enjoy an active lifestyle, making our supplements beneficial for mobility.
Muscles also burn calories better than fat, making them instrumental for weight loss and maintaining a lean body.
Inflammation and diabetes management
Inflammatory conditions can prevent you from enjoying a healthy lifestyle, but Vitamin D3 can boost your immune system, and its anti-inflammatory properties benefit a range of conditions, including arthritis.
However, it can also play a significant role in insulin management, and one tablet daily could help you manage the condition more effectively.
Kidney function
The kidneys are essential organs that require various nutrients to function correctly. Vitamin D3 is instrumental in promoting kidney health because it can promote normal blood calcium levels. Some people also use it to treat and slow down the progression of kidney disease.
