K2 + D3 + Magnesium Glycinate

Nutra-Life K2 + D3 + Magnesium Glycinate brings together three nutrients with deeply complementary roles in bone health, calcium metabolism, and muscle function.

Vitamin K2 (as MK-7), Vitamin D3, and Magnesium Glycinate are each well-researched individually, but their value together lies in how they work as a system: Vitamin D3 supports calcium absorption from the gut, Vitamin K2 helps direct that calcium into bones and teeth rather than soft tissues and arterial walls, and Magnesium supports the activation of Vitamin D in the body alongside its own foundational role in bone, muscle, and nervous system health.

• Bone health and density - a three-nutrient combination that works synergistically to support healthy bone mineral density, calcium absorption, and bone integrity - particularly relevant for those at risk of bone density loss
• Vitamin K2 (MK-7) - Menaquinone-7 is the most bioavailable and longest-acting form of Vitamin K2; it supports the activation of osteocalcin - the protein that binds calcium to bone - and helps prevent calcium from depositing in soft tissues and arterial walls
• Vitamin D3 - supports the absorption of calcium and phosphorus from the gut, contributes to normal bone mineral density, and supports immune function, muscle function, and nervous system health; particularly relevant for those with limited sun exposure
• Vitamin D metabolism support - Magnesium is required for the conversion of Vitamin D into its active form in the body; without adequate magnesium, supplemental Vitamin D cannot be properly activated or utilised
• Magnesium Glycinate - the chelated glycinate form supports bone health, muscle relaxation, nerve function, and energy production, with superior absorption and tolerability compared to less refined magnesium forms
  
• Cardiovascular system support - Vitamin K2 plays a role in maintaining arterial flexibility and cardiovascular health by helping prevent soft tissue calcification; Magnesium also contributes to normal heart and blood vessel function
• Healthy teeth -the K2 and D3 combination supports calcium utilisation in dental tissue as well as bone, contributing to healthy tooth structure
• Supports those with limited sun exposure - the Vitamin D3 dose addresses the gap that occurs when sunlight exposure, the body's primary source of Vitamin D is insufficient
• Reduces feelings of tiredness and fatigue - Magnesium contributes to normal energy-yielding metabolism, and Vitamin D supports normal muscle and nervous system function

Free from gluten, wheat, animal products, dairy, egg, artificial flavours, artificial sweeteners, and preservatives. Suitable for vegetarians.

Adults take 1 tablet daily with food, or as directed by your healthcare professional.

Always read the label and use only as directed. Vitamins and minerals are supplementary to and not a replacement for a balanced diet. If symptoms persist, consult your healthcare professional.

Suitable during pregnancy and breastfeeding. Not recommended for people taking blood-thinning medication (anticoagulants such as warfarin) without medical supervision, as Vitamin K2 can interact with these medications. If taking prescription medication or managing a medical condition, consult your healthcare professional before use. Keep out of reach of children. Store in a cool, dry place.

Nutra-Life K2 + D3 + Magnesium Glycinate is built around the increasingly well-understood relationship between three nutrients that work together as a system - rather than as isolated supplements - to support bone health, calcium metabolism, and cardiovascular function.

Vitamin D3 is the starting point. It drives the absorption of calcium from the digestive tract and into the bloodstream, and without adequate Vitamin D, the body cannot absorb calcium effectively regardless of how much is consumed through diet or supplementation. However, simply increasing calcium in the blood creates its own risk - calcium that is not properly directed into bones can deposit in soft tissues and arterial walls, contributing to calcification. This is where Vitamin K2 becomes critical. Vitamin K2 - specifically as Menaquinone-7 (MK-7), the most bioavailable and longest-acting K2 form - activates two key proteins: osteocalcin, which binds calcium to bone and teeth, and Matrix GLA Protein (MGP), which inhibits calcium from depositing in soft tissues and arterial walls. The combination of D3 and K2 therefore not only supports bone mineral density but also supports cardiovascular health by helping keep calcium in the right places.

Magnesium completes the triad. Most people are unaware that Vitamin D supplementation actually requires adequate magnesium to work properly - magnesium is a necessary cofactor for the enzymatic conversion of Vitamin D into its active hormonal form in the liver and kidneys. Without sufficient magnesium, supplemental Vitamin D may remain inactive. Magnesium also works directly alongside calcium and Vitamin D in bone mineralisation, contributes to muscle relaxation and neuromuscular function, and supports normal energy-yielding metabolism. Using the glycinate chelate form ensures good absorption and gentle tolerability compared to less refined forms such as magnesium oxide.

Why are Vitamin K2, Vitamin D3, and Magnesium better together than separately?
Each of these three nutrients plays a distinct but interdependent role in calcium metabolism and bone health. Vitamin D3 increases calcium absorption from the gut into the blood. Vitamin K2 directs that calcium into bones and teeth and away from soft tissues and blood vessels. Magnesium activates Vitamin D in the body and contributes directly to bone mineralisation and muscle function. Taking them together addresses the full pathway - absorption, activation, and utilisation, rather than just one part of it.

What is Vitamin K2 MK-7 and why is it the preferred form?
Menaquinone-7 (MK-7) is a naturally occurring form of Vitamin K2 with a much longer half-life in the body than the more common MK-4 form - MK-7 remains active in the bloodstream for up to three days compared to a few hours for MK-4. This makes it more effective at maintaining consistent K2 activity with a single daily dose. MK-7 is the form used in the majority of modern Vitamin K2 clinical research.

Is 600IU of Vitamin D3 enough?
600IU is a solid daily maintenance dose of Vitamin D3, sitting above New Zealand's Estimated Average Requirement for most adults and consistent with common supplementation guidelines for supporting Vitamin D status alongside regular diet and moderate sun exposure. Those with confirmed Vitamin D deficiency or very limited sun exposure may require a higher dose under healthcare professional guidance.
