The role of Vitamin D in the immune system has been recognised for many years, however it was only in recent years that the implications of Vitamin D deficiency on the immune system have become clearer. 

Several different types of cells in the body, including immune cells, contain the receptor for Vitamin D, which means they can respond to Vitamin D molecules, triggering different reactions in the body. No wonder Vitamin D can affect so many aspects of health including bone health, cardiovascular health, immunity, autoimmune disease, type I diabetes, and mental health too.

Getting sufficient Vitamin D contributes to the healthy function of our immune systems, improving resistance against certain diseases. It also plays a role in the process of cell division as well as ensuring the maintenance of healthy bones and teeth.

Although classified as a vitamin, D3 cleverly transforms into a hormone in the body and circulates in the bloodstream to help in the absorption of calcium and phosphorous. This is perhaps one of the most vital functions that Vitamin D3 performs.

Daily supplementation of vitamin D (especially during the winter months) is such a simple and cost-effective way to support your body’s health and performance.

Our science-led, evidence backed formulation ensures you get an optimal source and quantity of vitamin D3 to help you perform and recover at your best every day.

Bone Health

Vitamin D is necessary for strong bones and muscles. Without Vitamin D, our bodies cannot effectively absorb calcium, which is essential to good bone health.

Immune Health

There are Vitamin D receptors and activating enzymes on the surfaces of all White Blood Cells.

Vitamin D plays an important role in keeping the immune system healthy and balanced.

Mental Health

Researchers believe that because vitamin D is important to brain function, insufficient nutrient levels may play a role in depression and other mental illnesses.

Muscle Function

Vitamin D supplementation has been shown to increase muscle strength and higher serum levels of vitamin D in the blood are also associated with reduced injury rates and overall improvement in sports performance.

Take 4 tablets daily. Each tablet is 1000IU (Serving size = 4000IU)

How many tablets do you get in a packet?

There are 120 tablets in each packet of active vitamin D3 which is the equivalent of 30 servings of 4 tablets daily (1 month's supply)

Is active vitamin D3 suitable for vegans or vegetarians?

Yes! Active vitamin D3 is suitable for vegetarians.

Is 4000IU too much or too little vitamin D3?

It's neither! In fact, its the optimum amount. According to new research and recommendations, a 4000IU daily serving is now recommended for the majority of the population all year round, but expecially so during the colder darker months when exposure to natural sunlight is limited (October - April) in the northern hemisphere.

The Purpose

Vitamin D3, sometimes known as the ‘sunshine vitamin’ is produced naturally in the skin when it is exposed to sunlight. You can also get it through certain foods. However, many factors can affect your ability to get enough vitamin D through the sun alone. 

These factors include being in an area with high pollution, using sunscreen, spending more time indoors, living in big cities where buildings block sunlight, having darker skin (the higher the levels of melanin, the less vitamin D the skin can absorb), or seasonally, for example during winter. 

Ensuring we get adequate vitamin D into our diet is crucial for both our overall health and performance and here at U Perform we follow the science and current recommendations for daily vitamin D supplementation sit at 4000IU per day. 

Can you take more? Yes, you can. But 4000IU is the optimal amount per day due to the bioavailability of vitamin D at the gut.
