Boncal: Advanced Calcium, Magnesium, Zinc & Vitamin D Supplement Tablets - Support Bone Health & Immunity

Boncal: Advanced Calcium, Magnesium, Zinc & Vitamin D Supplement Tablets - Support Bone Health & Immunity, categorized under Joint, bone & connective tissue health in the Supplements vertical. It is scored on the Vyvata Scoring Framework — an independent 6-dimension rubric applied uniformly to every product Vyvata lists.

56/100 overall — Standard tier (50–69 band). Per-dimension breakdown: Evidence 65, Safety 60, Formulation 55, Manufacturing 52, Transparency 52, Sustainability 48. Scored as of 2026-08-24.

Boncal is a Turkish bone-health combination product delivering the classic Ca + Mg + Zn + D3 quartet, which does have supportive evidence for postmenopausal bone density (Tang 2007 meta-analysis of Ca+D). The formulation is missing vitamin K2 (MK-7), which the current evidence suggests is important for directing calcium to bone rather than soft tissue (Knapen 2013), and calcium carbonate versus citrate makes a real absorption difference (Heaney 1999). Small Turkish brand with limited manufacturing transparency at the reseller layer. Would move to Standard-high 62+ with K2 MK-7 added, calcium citrate specified, and D3 dose disclosed.

Strongest: Evidence at 65/100 (quality of published RCT support for the active ingredients at the label dose) and Safety at 60/100 (adverse-event profile, interaction risk, and dose ceiling). Weakest: Transparency at 52/100 (dose disclosure vs proprietary blends, and honesty of marketing claims) and Sustainability at 48/100 (sourcing practices, packaging, and corporate practice). All six dimensions feed the overall Vyvata score; a weakness on any one dimension pulls the overall down proportionally.

No third-party certifications (NSF, USP, ConsumerLab, or equivalent) were on record at the time of scoring. This affects the Manufacturing dimension score. The manufacturer may test internally or have obtained certification more recently — check the current product label for the most up-to-date information.

Would move to Standard-high 62+ with K2 MK-7 added, calcium citrate specified, and D3 dose disclosed.
