DNA Sports D3 + K2 - 60 Caps

DNA Sports D3 + K2 is a dietary supplement formulated to support bone health, cardiovascular function, calcium metabolism, and immune performance by combining two essential fat-soluble vitamins: vitamin D3 (cholecalciferol) and vitamin K2 (menaquinone-7, or MK-7). This supplement is intended for people who want to maintain or increase their skeletal strength, avoid arterial calcification, boost their immune systems, or maximise their body's use of calcium. It is especially useful for people with vitamin D deficiency, those with low dietary intake of vitamin K2, postmenopausal women, older adults, athletes under heavy training load, and anyone interested in overall health support.

Key benefits:
- Bone health
- Cardiovascular health
- Immunity
- Mood and Wellbeing

Vitamin D contributes to the absorption and utilisation of calcium and phosphorus, helping to maintain bones and muscle function. Paired with Vitamin K2, this can further aid bone health and integrity but also helps to regulate blood clotting, reducing arterial calcification and improving cardiovascular health. To ensure you get the best out of supplementing with vitamin D3 and K2, we use quality sourced ingredients which have been shown to be the most bioavailable form to use.

Vitamin D3 (cholecalciferol) is the natural form of vitamin D synthesised in the skin upon exposure to UVB radiation and is more effective than vitamin D2. Once ingested or produced, vitamin D3 is converted in the liver, then in the kidneys to an active hormone, which binds to the vitamin D receptor and influences the expression of hundreds of genes. Its most well-known function is promoting calcium and phosphate absorption from the gut and facilitating normal bone mineralisation. It also modulates immune responses by enhancing pathogen-fighting effects of monocytes and macrophages and reducing pro-inflammatory cytokines. Vitamin D3 has roles in neuromuscular function, cell differentiation, and inflammation regulation. Deficiency is associated with bone softening (osteomalacia), increased fracture risk, muscle weakness, autoimmune diseases, cardiovascular dysfunction, and elevated infection susceptibility.

Vitamin K2, particularly in the form of menaquinone-7 (MK-7), is critical for the activation of vitamin K-dependent proteins that regulate calcium homeostasis and bone metabolism. MK-7 activates osteocalcin, a protein secreted by osteoblasts that binds calcium and integrates it into the bone matrix, promoting bone density and strength. It also activates matrix Gla-protein, which inhibits vascular calcification by preventing calcium deposition in blood vessels. Without adequate vitamin K2, calcium absorbed under the influence of vitamin D3 can be misdirected into soft tissues rather than bone, increasing the risk of arterial stiffness and cardiovascular disease. MK-7 has a long half-life, providing sustained biological activity and superior efficacy compared to other K2 forms such as MK-4.

The synergy between vitamins D3 and K2 is central to this supplement: while vitamin D3 increases calcium absorption, vitamin K2 ensures that this calcium is correctly utilised, deposited into bones, and kept out of arteries. Their combination optimises skeletal integrity while protecting cardiovascular health, making DNA Sports D3 + K2 an ideal supplement for those concerned about bone loss, osteoporosis, arterial calcification, or imbalanced calcium metabolism.

Beneficial Effects From The Combination:

- Bone Health Reinforcement: DNA Sports Vitamin D3 + K2 provides essential nutrients that work in tandem to promote strong and resilient bones. Vitamin D3 aids in calcium absorption, while Vitamin K2 directs calcium to the bones and away from arteries, contributing to a solid foundation for your skeletal structure. Vitamin D3 enhances intestinal absorption of calcium and phosphorus—two minerals essential for bone mineralisation—and ensures their availability in the bloodstream. However, without vitamin K2, this calcium may not be properly utilised. K2 activates osteocalcin, a protein synthesised by osteoblasts (bone-forming cells), which binds calcium and incorporates it into the bone matrix, thus reinforcing bone density and structural integrity. This synergy is crucial in preventing demineralisation, reducing the risk of fractures, and preserving skeletal strength with age. Regular intake supports peak bone mass development in younger individuals and helps counteract age-related bone loss in older adults, especially postmenopausal women prone to osteoporosis.

- Cardiovascular Health Support: Vitamin K2 supports cardiovascular health by preventing calcium buildup in arteries, promoting healthy blood flow, and maintaining heart function. DNA Sports Vitamin D3 + K2 helps safeguard your heart's vitality, enabling you to lead an active and fulfilling life. Calcium that is absorbed under the influence of vitamin D3 can, without proper regulation, contribute to arterial plaque and vascular stiffening if deposited in the wrong tissues. Vitamin K2 ensures calcium is directed away from soft tissues and toward skeletal storage by activating matrix Gla-protein, a potent inhibitor of arterial calcification. This helps preserve vascular elasticity, reduce the risk of hypertension, and maintain optimal circulation. The prevention of arterial calcification is crucial for long-term cardiovascular function, and consistent supplementation with D3 and K2 supports both proactive heart care and the mitigation of risks associated with excess calcium intake.

- Immune System Optimization: Strengthen your body's natural defences with the immune-boosting power of DNA Sports Vitamin D3 + K2. These vitamins play a crucial role in supporting a robust immune system, keeping you resilient against environmental challenges. Vitamin D3 acts as an immunomodulator, enhancing the pathogen-fighting ability of macrophages and dendritic cells while modulating the inflammatory response through effects on T and B lymphocytes. It supports the production of antimicrobial peptides such as cathelicidins, which help the body combat viral and bacterial infections. A deficiency in D3 has been linked to increased vulnerability to respiratory infections, autoimmune conditions, and prolonged inflammation. While the role of vitamin K2 in immunity is not as direct, it contributes to immune resilience by reducing chronic inflammation and supporting optimal cellular function, which is vital for coordinated immune responses and overall immune system balance.

- Mood and Mental Well-being: Elevate your mood and mental clarity with the mood-regulating benefits of Vitamin D3. As an essential vitamin for brain health, D3 helps maintain a positive outlook and cognitive function, ensuring you stay focused and emotionally balanced. Vitamin D receptors are widely distributed throughout brain tissue, and D3 influences the synthesis of neurotransmitters such as serotonin and dopamine—key players in regulating mood, motivation, and emotional stability. Studies have linked low levels of vitamin D with higher rates of depression, anxiety, and cognitive decline. Adequate D3 levels contribute to neuroprotection, reduce oxidative stress in neurones, and support the health of the hippocampus, the region of the brain involved in memory and emotional regulation. By ensuring stable mood and mental clarity, DNA Sports D3 + K2 helps you remain mentally sharp, emotionally resilient, and better equipped to handle daily stressors and mental demands.

DNA Sports Vitamin D3 + K2 is the perfect supplement to support your overall health and well-being. By combining the powerful benefits of vitamins D3 and K2, it promotes strong, resilient bones, supports cardiovascular health by preventing arterial calcification, and optimises immune system function to keep you resilient against illness. Additionally, the mood-boosting properties of vitamin D3 help maintain mental clarity and emotional balance, so you can stay focused and positive every day. Whether you're looking to strengthen your bones, protect your heart, or improve your immune and mental health, DNA Sports Vitamin D3 + K2 provides comprehensive support.
