Vitamin D3 deficiency is common, especially in low-sunlight regions. At the same time, proper calcium balance depends on more than vitamin D alone.
That’s where Vitamin D3 + K2 work together.
Vitamin D3 helps your body absorb calcium. Vitamin K2 helps direct that calcium to the bones, where it is needed.
Purovitalis Liposomal Vitamin D3 + K2 combines both in one structured formula, supporting how calcium is absorbed and used in the body.
With liposomal delivery, this D3 K2 supplement is designed to improve absorption compared to standard capsules.
The result: Support for immune health, bone strength, and long-term cellular balance.
¹ Vitamin D contributes to the normal function of the immune system
² Vitamin D contributes to normal absorption and utilization of calcium and phosphorus
³ Vitamin D contributes to normal muscle function
⁴ Vitamin K contributes to normal blood clotting

Support your body with a balanced D3 + K2 approach
Vitamin D3 is one of the most studied vitamins, with evidence extending beyond bones into immunity and longevity:
Vitamin D & Immune Health
Research shows that vitamin D modulates immune cell activity, supporting balance and resilience, especially in individuals with deficiency. Study
Telomere Length & Cellular Aging
NIH-backed research suggests vitamin D supplementation may slow cellular aging by protecting telomeres, the protective caps on chromosomes that shorten with age. Study
Exercise & Longevity
A combined analysis found vitamin D, alongside omega-3s and regular exercise, improved longevity markers in older adults. Study
Vitamin D Deficiency Prevalence

Standard vitamin D capsules are poorly absorbed, especially in people with digestive issues or low-fat diets.
Purovitalis Liposomal Vitamin D3K2 solves this with:
Liposomal encapsulation — 4x better absorption than standard capsules
High-dose (2000 IU) D3 for restoring optimal levels
Vitamin K2 (75 MCG) supports proper calcium utilization
Vegan formulation — made with sunflower lecithin, no animal ingredients
European GMP production — purity and consistency guaranteed
This creates a more balanced approach than vitamin D alone.

¹ Vitamin D contributes to the normal function of the immune system and maintenance of normal bones (EFSA).
² Vitamin K contributes to the maintenance of normal bones and normal blood clotting (EFSA).
Vitamin D deficiency builds up over months, and it also takes time to restore healthy levels. Research suggests steady intake for at least 8–12 weeks is needed to see real improvements in immunity and energy. That’s why our subscription includes a 3-month minimum, for lasting results.

This supplement is suitable for people who get limited sun exposure, want to support immune function, or are looking to maintain bone health and calcium balance.
While sunlight is a natural source of Vitamin D3, factors such as the time of year, latitude, skin type, age, and use of sunscreen can affect the body’s ability to produce Vitamin D3. Moreover, many people find it hard to get enough sun exposure, especially in the winter. In these cases, Vitamin D3 supplements can help ensure you get the adequate amount you need.
