Bone & Joint Health.

Calcium, magnesium, K2, and joint-mobility formulations at studied doses.

Bone is the body's largest mineral reservoir and a dynamic tissue that remodels throughout adult life. Joint cartilage depends on connective-tissue substrate that turns over more slowly than skin. EX1's Bone & Joint Health catalog brings calcium, magnesium, D3, K2, and collagen substrate together at the doses the trial literature anchors to.

Why this category matters

Bone and joint health refers to the structural integrity of the skeletal system and the cartilaginous and ligamentous tissue at every joint, both of which respond to dietary mineral supply and connective-tissue protein status across adult life.

ICMR-NIN sets the adult calcium RDA at 1000 mg daily; Indian dietary intake routinely falls below this across age groups. Calcium alone is not enough: D3 enables absorption, K2 (MK-7) directs calcium into bone matrix rather than soft tissue, and magnesium supports the calcium-magnesium balance every muscle contraction relies on.

ICMR-NIN (2020) sets the calcium RDA for adult Indians at 1000 mg per day, with higher reference intakes for post-menopausal women and older adults. Vitamin K2 in the MK-7 form has the longest serum half-life among K2 forms and is the form used in most modern bone-density supplementation trials.

How to choose a bone & joint health supplement

  1. The bone stack is calcium + magnesium + D3 + K2 + zinc

    Calcium alone does not build bone. The full stack works as a system; deficits in any of the cofactors leave the rest under-leveraged.

  2. Calcium form matters

    Calcium citrate-malate absorbs without stomach acid and sits gentler on the gut than carbonate. Trial doses anchor to elemental calcium, not compound weight.

  3. K2 should be MK-7, not MK-4

    MK-7 has a 72-hour serum half-life and supports calcium-routing on a single daily dose. MK-4 clears in hours and requires multiple daily doses to maintain effect.

  4. Joint support: collagen peptides at the studied dose

    Hydrolysed Type I and III collagen peptides at 10 g per day are the form and dose evaluated in joint-comfort and skin-elasticity trials. The peptide form is what absorbs; whole collagen protein is not orally bioavailable.
