Bone and Joint Supplements: Calcium, Vitamin D, K2 and Magnesium

This collection brings together bone and joint supplements in Portugal: vitamin D3, vitamin K2 (MK-7), magnesium, calcium, collagen, glucosamine and chondroitin from brands such as NOW Foods, Osavi, OstroVit, Swanson and Life Extension. A varied diet, moderate sun exposure and regular physical activity remain the foundation.

Vitamin D3: vitamin D contributes to the maintenance of normal bones, to normal absorption and utilisation of calcium and phosphorus and to the maintenance of normal muscle function. You will find several strengths in vitamin D; with high doses (above 100 mcg/4000 IU per day) follow the label and consult your doctor.

Vitamin K2 and calcium: vitamin K contributes to the maintenance of normal bones and to normal blood clotting. Calcium is needed for the maintenance of normal bones and teeth. Many formulas combine D3 and K2 in a single capsule.

Magnesium: magnesium contributes to the maintenance of normal bones, to normal muscle function and to the reduction of tiredness and fatigue. Compare glycinate, citrate and malate in the magnesium section.

Collagen and cartilage: vitamin C contributes to normal collagen formation for the normal function of cartilage and bones. Hydrolysed collagen, type II collagen (UC-II), glucosamine, chondroitin and MSM are described by composition and dose, without health claims. See collagen and cartilage.

Frequently asked questions

Why combine vitamin D3 with K2? For convenience: both contribute to the maintenance of normal bones. If you take anticoagulants, speak to your doctor before taking vitamin K.

What is the difference between magnesium forms? Glycinate, citrate and malate differ in the compound the magnesium is bound to and in the amount of elemental magnesium per serving. Always compare the elemental magnesium stated on the label and keep to the 250 mg/day limit for supplemental magnesium.
