Vitamin D and Calcium for the Prevention of Fracture: Systematic Review and Meta-Analysis
This high-impact systematic review and meta-analysis covering 11 RCTs (34,243 participants for vitamin D alone) and 6 RCTs (49,282 participants for vitamin D + calcium) found an important distinction: vitamin D supplementation alone showed no significant association with reduced fracture risk at standard doses. However, combined daily supplementation of vitamin D and calcium was associated with a 16% reduced risk of hip fracture. This is a critical nuance — vitamin D needs calcium co-factors to deliver meaningful bone protection, and it highlights why the pairing with vitamin K2 (which directs calcium into bone) in this supplement is scientifically rational.
Source — JAMA NetworkMenaquinone-4 Supplementation, Coronary Artery Calcification, and Arterial Stiffness
This clinical study in 26 patients investigated whether vitamin K2 (MK-4 form at 45 mg/day) could reduce coronary artery calcification and arterial stiffness. While coronary calcification continued to increase (as is typical in patients with pre-existing calcification), arterial stiffness (brachial-ankle pulse wave velocity) was significantly reduced in patients with the highest baseline vitamin K insufficiency. This finding illustrates the mechanistic synergy with vitamin D3: vitamin D increases calcium absorption, while K2 (via carboxylation of matrix Gla protein) actively inhibits calcium deposition in soft tissues like arteries — directing it toward bone instead. This "calcium routing" effect is the main scientific rationale for combining D3 and K2.

This review establishes that vitamin D is an immunomodulatory hormone as well as a bone mineral. Once immune cells produce the active form 1,25(OH)₂D, it acts on both the innate and adaptive immune systems — boosting antimicrobial peptide production, modulating T-cell responses, and stabilizing endothelial membranes. Low serum 25(OH)D levels are consistently associated with increased risk of respiratory infections, autoimmune conditions (type 1 diabetes, multiple sclerosis, rheumatoid arthritis), and sepsis. The 2000 IU dose in this supplement corresponds closely to levels studied in immune support contexts.
Source — MDPICombined Exercise + Vitamin D3 for Musculoskeletal Recovery
This systematic review of 7 RCTs (792 older adults) assessed the combined effect of resistance exercise training and vitamin D3 supplementation on musculoskeletal health. Meta-analysis found a large, significant improvement in lower limb muscle strength in the group combining exercise with vitamin D3 (p<0.00001), with additional significant benefits in physical performance (SPPB score), timed-up-and-go speed, and femoral neck bone density in groups using the combination approach. The review concludes that vitamin D3 supplementation provides tentative additive benefit to exercise training for muscle strength — which directly supports its use as a post-workout recovery supplement.
Source — NIH - PubMed CentralBone Health — Meta-Analysis
This meta-analysis pooled 16 RCTs covering 6,425 participants and found that vitamin K2 supplementation significantly improved bone mineral density and reduced fracture incidence in postmenopausal women. The mechanism is well established: vitamin K2 acts as a cofactor for carboxylation of osteocalcin, allowing it to bind hydroxyapatite and incorporate calcium into bone mineral matrix — directly complementing vitamin D3's role in calcium absorption. Without adequate K2, calcium absorbed under vitamin D3 stimulation may not be properly deposited into bone.

FAQ
How quickly will I see results?
Bone health is a long-term process. Most customers notice improved joint comfort and muscle strength within 4 to 6 weeks. Measurable improvements in bone density typically require 3 to 6 months of consistent daily use.
Why do I need Vitamin K2 with Calcium?
Vitamin K2 directs calcium to your bones and teeth rather than allowing it to accumulate in soft tissues and arteries. This combination is essential for safe and effective calcium supplementation.
Is this suitable for women over 40?
Yes. The formula is specifically beneficial for women approaching or experiencing menopause, when bone density naturally begins to decline.
How many strips are in one box?
Each box contains 30 strips — a complete 30-day supply.
Can I take this with other Stryō strips?
Yes. Bone & Strength pairs well with Stryō Focus Energy for a complete daily health and vitality routine.
