Vitamin D3, technically a prohormone, is activated in the body to regulate a wide range of biological processes. A key role is enhancing the absorption of calcium and phosphorus-essential minerals for maintaining strong, healthy bones and teeth. It also binds to receptors in most cells, influencing the expression of over 2,000 genes.

While vitamin D3 is naturally synthesised in the skin through sun exposure, several factors-such as limited sunlight, ageing, sunscreen use, and darker skin tones-can impair the body’s ability to produce sufficient levels. This is especially relevant in the UK and other northern climates.

Dietary sources of vitamin D are limited. They include oily fish (such as salmon, mackerel, and sardines), egg yolks, liver, and fortified foods like breakfast cereals and plant-based milk alternatives. Yet even with a varied diet, many people fall short-particularly in winter or when sun exposure is restricted.

Given that a significant proportion of the population now spends up to 90% of their time indoors, vitamin D deficiency has become increasingly common. This can contribute to issues such as reduced bone density and, in severe cases, conditions like rickets or osteomalacia.

This supplement is ideal for people who:

• People who want daily support for bones, teeth, muscles and immune function
• Anyone with limited sun exposure due to lifestyle, climate or season
• Indoor workers, night-shift patterns, or those mostly covered by clothing outdoors
• Individuals seeking the active form of vitamin D paired with Vitamin K2
• Those looking for a clean, practitioner-led formula with purposeful ingredients

The D3 + K2 combination, made with integrity from concept to capsule.

We formulate this product using the body’s preferred, active form of Vitamin D3, combined with all-trans MK-7 K2 for complementary support. Because we manufacture in our own UK facility, every stage - from ingredient sourcing to encapsulation - is overseen for purity, precision and integrity. You can trust that every capsule contains only what’s needed, and nothing that isn’t.

Key Benefits of Vitamins D & K

✔ Supports Normal Absorption and Utilization of Calcium and Phosphorus

Vitamin D helps the body absorb and utilise calcium and phosphorus-key minerals for healthy bones and teeth. Deficiency can lead to bone deformities such as rickets in children, and bone pain caused by a condition called osteomalacia in adults.

✔ Helps Maintain Normal Blood Calcium Levels

Vitamin D plays a crucial role in maintaining normal blood calcium levels. It aids in the absorption of calcium from the diet and regulates its levels in the bloodstream, ensuring proper functioning of the nervous and muscular systems. Vitamin K contributes by activating proteins such as osteocalcin, which help bind calcium to the bone structure, further supporting bone density and strength.

✔ Contributes to the Maintenance of Normal Bones and Teeth

Adequate Vitamin D levels are essential for bone mineralisation and remodelling. They help ensure proper deposition of calcium and phosphorus in the bone matrix, supporting skeletal strength and helping reduce the risk of fractures.

✔ Supports the Normal Function of the Immune System

Vitamin D plays a key role in regulating immune cells, including T cells and B cells, which identify and target harmful pathogens and abnormal cells. It also supports the differentiation of monocytes and macrophages-immune cells responsible for engulfing and eliminating pathogens. By ensuring these cells develop and function properly, Vitamin D helps maintain a robust immune response. Additionally, it contributes to the innate immune system, the body’s first line of defence, by activating immune cells to respond quickly to infections.

✔ Plays a Role in the Process of Cell Division

Vitamin D is involved in cellular proliferation and differentiation processes, influencing gene expression related to cell cycle regulation.

✔ Supports Normal Blood Clotting

Vitamin K plays a key role in the production of clotting factors, helping to maintain normal blood coagulation. This is essential for wound healing and overall circulatory health.
