Vitamin D3 Drops with K2

Unlike standard vitamin D supplements, this formula combines vitamin D3 with K2 to support both calcium absorption and proper calcium distribution in the body. Many in the UK face vitamin D deficiency, especially during the colder months, which can affect bone strength, immune balance, and muscle function. This supplement helps fill those nutritional gaps by providing the form of vitamin D the body naturally produces from sunlight, paired with K2 to direct calcium to where it’s needed most. By taking this, you support your bones, muscles, and immune health year-round, helping you feel stronger and more resilient.

For over 40 years, Nutri Advanced has helped people take charge of their health with science-backed nutrition. Now part of Metagenics, a global leader in functional supplements, the brand remains committed to tackling health concerns at their root. Every formula is carefully crafted using the latest research and high-quality ingredients to support real, lasting wellness. With a strong focus on quality, sustainability, and expert guidance, Nutri Advanced continues to make better health more accessible—helping people feel their best every day.
