Bone Strength Take Care by New Chapter

If your DEXA scan shows low bone density, or your diet is light on dairy or fortified foods, a calcium supplement with vitamin K2 and D3 fits. The 905 mg of algae calcium here is a practical maintenance dose for post‑menopausal women, vegans on restrictive diets, and long‑term proton pump inhibitor users who eat less calcium. Check Vitamin D, 25-Hydroxy first; if your level is low, this built‑in 1,000 IU helps, but true deficiency usually needs higher D3 separately.

Algae‑sourced calcium is a whole‑mineral complex from Lithothamnion, mainly calcium carbonate with trace magnesium and silica. Taken with food, it absorbs similarly to other carbonates and provides the raw material for bone. Vitamin D3 (cholecalciferol) increases calcium absorption and helps keep parathyroid hormone (the signal that pulls calcium from bone) in check. Vitamin K2 as MK‑7 activates osteocalcin (a bone‑binding protein) and matrix Gla protein (a protein that limits calcium deposits in arteries). Expect bone turnover markers like P1NP or CTX to shift within 8–12 weeks; DEXA changes take 6–12 months.

Take three tablets daily with food, ideally split as 2 with a meal and 1 with another meal for steadier absorption. Calcium competes with iron and zinc, so separate from iron or high‑zinc supplements by at least two hours. Hydrate and keep fiber up if you tend toward constipation. If you already eat 800–1,000 mg of calcium from food, consider taking fewer tablets and recheck intake rather than overshooting.

Space calcium at least four hours from levothyroxine, and two hours from tetracycline or quinolone antibiotics, bisphosphonates, or strontium ranelate due to absorption interference. Recurrent kidney stone formers should review a 24‑hour urine calcium before adding supplements. Skip or use only with clinician guidance if you have high blood calcium, sarcoidosis, hyperparathyroidism, or chronic kidney disease. For statin or warfarin users, K2 is generally compatible, but if you take warfarin, do not change vitamin K intake without prescriber input.
