£18.88 inc. VAT
PRL D3 Serum (Vitamin D3) by Premier Research Labs is one of the most bio-available and non-toxic Vitamin D3 nutritional supplements available.
PRL D3 Serum provides a highly bioavailable form of vitamin D3 delivered in a simple liquid format for convenient daily use. Sourced from lanolin in sheep’s wool, the vitamin D3 is carefully extracted and purified, with testing confirming the absence of methanol, hexane and chlorobenzene residues. The formula is suspended in extra virgin olive oil to support effective absorption, while natural vitamin E acts as a gentle antioxidant preservative.
Vitamin D3 is valued for its role in supporting normal immune function, the maintenance of normal bones and teeth, and healthy muscle function. Many individuals choose a liquid D3 supplement for its ease of dosing and reliable uptake, making it suitable for those who prefer an oil-based delivery system over capsules or tablets. Each 5-drop serving provides a generous 5000 IU, offering a potent and efficient way to help maintain optimal vitamin D status throughout the year.
With just three ingredients — vitamin D3, extra virgin olive oil and natural vitamin E — this formula is intentionally clean and free from unnecessary additives. It is suitable for vegetarians but not for vegans due to its lanolin-derived source. PRL D3 Serum is a straightforward, high-purity option for those seeking dependable nutritional support for overall wellbeing.
Directions: Take 5 drops a day with any meal. If you are pregnant or lactating, consult a physician before use.

Vitamin D3 is now regarded as a very important nutrient for helping us to maintain optimum health. It is one of the few essential nutrients that cannot generally be consumed in sufficient amounts in food. (Best nutritional sources being salmon, mackerel, sardines and tuna, although they only contain around 5mcg per serving.) Usually we meet our Vitamin D3 requirement through exposing our skin to sunlight, which is one reason why we usually feel so good when we are on sunshine holidays or during the summer months. This nutrient plays many invaluable roles in our bodies:
- Supports immune function
- Is heavily implicated as being protective to the respiratory system
- Necessary for strong and healthy bones
- Needed for proper function of the thyroid
- Helps in calcium absorption
- Plays a role in cardiovascular function
- Supports healthy inflammatory response
- Needed for normal cell division
Most people in temperate climates do not receive sufficient sun exposure to meet their vitamin D requirement, especially during the cooler months of the year. As a result, most are deficient of circulating vitamin D3. The RDA of vitamin D3 in Europe is 5mcg per day, but this is believed by many scientists now to be a gross underestimation of what is needed for optimum health.
