Everyday Bone and Joint Supplement — Sura Vitasan
Osto-Fort is a multi-nutrient formula based on microcrystalline hydroxyapatite. It can be beneficial for adults who want to support the maintenance of bones and cartilage through their daily routine.
As we age, maintaining healthy bones and joints can be more challenging without adequate nutrient intake. Sura Vitasan's bone and joint supplement Osto-Fort offers a comprehensive formula, designed for those who want to integrate bone care into their daily routine in a practical way. The base is microcrystalline hydroxyapatite — a natural source of calcium, phosphorus, and bone collagen proteins — supplemented with vitamin D3, vitamin K2, magnesium, zinc, manganese, and a set of plant extracts and amino acids. Formulated without gluten and dairy, in vegetable capsules that are easy to integrate into meals.
The base of Osto-Fort is microcrystalline hydroxyapatite (MCHA) — a form of calcium and phosphorus derived from bovine bone, which also provides natural bone collagen proteins and the amino acids L-lysine and L-proline, natural constituents of connective tissue. This calcium source is combined with magnesium (bisglycinate and oxide), zinc, manganese, and copper — all mineral cofactors with recognized functions in maintaining normal bones. Boron completes the mineral spectrum. In terms of vitamins, vitamin D3 (cholecalciferol) and vitamin K2 in dual form (menaquinone-4 and menaquinone-7) stand out, along with vitamin C for the normal functioning of cartilage and bones, and also thiamine, vitamin B12 (methylcobalamin), and folate (calcium L-methylfolate).
The spectrum of plant-derived compounds includes horsetail extract (Equisetum arvense, with 7% silica), glucosamine from Aspergillus niger, turmeric extract (Curcuma longa, 95% curcuminoids), grape seed extract (Vitis vinifera, 95% PACs), green tea extract (Camellia sinensis, 75% EGCG), lutein, and lycopene. These compounds are traditionally used in wellness contexts and can support musculoskeletal care routines — without constituting authorized health claims on their own.
How it fits in
Osto-Fort in vegetable capsules stands out from simpler calcium + vitamin D formulas by combining microcrystalline hydroxyapatite — which includes natural bone collagen — with a broader spectrum of cofactors: vitamin K2 (in dual MK-4 and MK-7 forms), zinc, manganese, copper, boron, amino acids, and botanicals. The 90-capsule version is suitable for a first experience with the product; the 180-capsule version offers greater value and economy for continuous use.
