OsteoDefence — Calcium, Magnesium, Vitamins D3 & K2 — 90 Capsules
✓ Calcium and Vitamin D3 contribute to the maintenance of normal bones — two of the key nutrients in this eleven-ingredient formulation
✓ Vitamin K2 (as Menaquinone-7/MK-7) contributes to the maintenance of normal bones alongside the mineral foundation
✓ Magnesium at 300mg (80% NRV), Zinc and Manganese each contribute to the maintenance of normal bones
OsteoDefence brings together eleven nutrients in a two-capsule daily dose. Rather than calcium alone, it includes the vitamins and minerals that work alongside it: Vitamin D3 to support absorption of calcium and phosphorus, Vitamin K2 in the long-acting MK-7 form, Magnesium at 80% of the daily NRV, and Vitamin C for collagen formation in bones and cartilage. A practical approach to covering the full nutritional picture without managing multiple separate supplements.
Why People Choose OsteoDefence
✓ Calcium contributes to the maintenance of normal bones — 266mg elemental calcium per daily dose (33% NRV) as Calcium Carbonate
✓ Vitamin D3 contributes to normal absorption and utilisation of calcium and phosphorus from food
✓ Vitamin K (as MK-7 Menaquinone-7) and Zinc both contribute to the maintenance of normal bones
✓ Magnesium at 300mg (80% NRV) contributes to normal protein synthesis and to a reduction of tiredness and fatigue alongside the bone-support nutrients
✓ 90 capsules — a 45-day supply at 2 per day — made in the UK to GMP Code of Practice and ISO 9001
More Than a Calcium Supplement
Calcium alone does not tell the complete story of bone nutrition. Vitamin D3 enables the body to absorb calcium from the diet — without adequate Vitamin D, calcium intake is less effective. Vitamin K2 (Menaquinone-7, the MK-7 form) has a longer half-life in the body than shorter-chain K2 variants and plays a distinct role in bone metabolism. Magnesium is the second-most abundant mineral in bone tissue. Zinc, Manganese and Copper are trace minerals that support the connective tissue framework around bone. Vitamin C contributes to collagen formation — collagen is a structural protein in both bone and cartilage. OsteoDefence covers all of these in one daily pair of capsules.
Making It Part of Your Daily Routine
Two capsules with a meal — breakfast or lunch works well, as the formula includes fat-soluble vitamins D and K that absorb better with food. The bottle provides a 45-day supply at the recommended dose. One important note: because the formula contains Vitamin K2 at 133% NRV, those taking anticoagulant medication (warfarin or similar blood thinners) should consult a doctor before starting. For most supplement routines, OsteoDefence slots in alongside a general multivitamin or as a standalone bone-nutrition supplement.
The Nutritional Picture for Bones
Research in bone nutrition consistently returns to the same group of nutrients: calcium, magnesium, phosphorus, the fat-soluble vitamins D and K, and the trace minerals zinc, manganese and copper. Boron (3mg per daily dose from Sodium Tetraborate Hydrate) appears in several bone-nutrition studies alongside this core group. Boron is not on the GB nutrition register for any approved health effect and is included here as an additional ingredient in a formula primarily anchored to the established mineral and vitamin set. Vitamin B6 and Folic Acid are also present at 100% and 71% NRV respectively, adding breadth to the nutritional profile.
Inside the Formula
Calcium Carbonate 266mg elemental (33% NRV) — Calcium contributes to the maintenance of normal bones and to normal muscle function. Provided as Calcium Carbonate, a stable and widely used calcium form.
Magnesium Oxide 300mg elemental (80% NRV) — Magnesium contributes to normal protein synthesis and to a reduction of tiredness and fatigue, alongside its structural role in bone. Magnesium Oxide is used here for its high density of elemental magnesium per capsule.
Vitamin D3 (Cholecalciferol) 25µg / 1000IU (500% NRV) — Vitamin D contributes to normal absorption and utilisation of calcium and phosphorus, and to the normal function of the immune system. Provided as Cholecalciferol D3.
Vitamin K2 (Menaquinone-7) 100µg (133% NRV) — Vitamin K contributes to the maintenance of normal bones and to normal blood clotting. MK-7 is the long-acting form of Vitamin K2. If you take anticoagulant medication, speak to your doctor before use.
Vitamin C (Ascorbic Acid) 80mg (100% NRV) — Vitamin C contributes to normal collagen formation for the normal function of bones and cartilage, and to the protection of cells from oxidative stress.
Zinc Bisglycinate 5mg (50% NRV) — Zinc contributes to the maintenance of normal bones and to the normal function of the immune system. Zinc Bisglycinate is a chelated form.
Manganese Citrate 1.4mg (70% NRV) — Manganese contributes to the maintenance of normal bones and to the normal formation of connective tissue.
Copper Citrate 1mg (100% NRV) — Copper contributes to maintenance of normal connective tissues and to normal iron transport in the body.
Vitamin B6 (Pyridoxine HCl) 1mg (71% NRV) — Vitamin B6 contributes to normal homocysteine metabolism, a nutritionally relevant role alongside the bone-focused ingredients in this formula.
Folic Acid 200µg (100% NRV) — Folate contributes to normal blood formation and has a role in the process of cell division and specialisation.
Boron (Sodium Tetraborate Hydrate) 3mg — Boron is not on the GB nutrition register for any approved health effect. It is included because it appears alongside the core bone-nutrition group in published nutritional research.

Frequently Asked Questions
Is OsteoDefence suitable for vegans?
No — suitable for vegetarians only. The HPMC capsule shell is plant-based, but the Vitamin D3 (Cholecalciferol) in the formula is derived from a non-vegan source.
I take warfarin or another blood thinner. Can I take OsteoDefence?
Only on medical advice. OsteoDefence contains Vitamin K2 at 133% NRV. Vitamin K affects blood clotting, and anticoagulant medications are sensitive to Vitamin K intake. Speak to your doctor before taking this product.
How many capsules per day and when should I take them?
Two capsules per day with food and water. The 90-capsule bottle provides a 45-day supply. Consistent daily use is recommended.
Can I take OsteoDefence alongside a general multivitamin?
Check the combined amounts of Vitamin D and Vitamin K if your multivitamin also contains these — both are fat-soluble and accumulate in the body. The Vitamin D in OsteoDefence is 500% NRV, so you may not need an additional Vitamin D supplement. Consult a healthcare practitioner if unsure.
Can I take OsteoDefence if pregnant or breastfeeding?
OsteoDefence is not recommended during pregnancy or breastfeeding. Speak to your healthcare practitioner about bone nutrition during this period.
