[Rescored via evidence crawl] Previous score 66 → new 74. Evidence found: Tang BM, et al. Use of calcium or calcium in combination with vitamin D supplementation to prevent fractures and bone loss. Lancet. 2007;370(9588):657-66. | Bischoff-Ferrari HA, et al. Pooled analysis of vitamin D dose requirements for fracture prevention. N Engl J Med. 2012;367(1):40-9.. Rationale: Calcium + magnesium + D3 is the evidence-backed bone-support triad. TIER-B evidence for reducing fractures in older adults (Tang 2007, Bischoff-Ferrari 2012). +8 uplift because this SKU adds the D3 that the Cal-Mag-Boron SKU omitted - making it a more complete standalone bone formula.
The Vyvata score's Evidence dimension measures the quality of published RCT support for a product's active ingredients at the label dose. Our source hierarchy: double-blind RCTs in MEDLINE-indexed journals > single-blind RCTs > open-label trials > observational studies > mechanism papers > N=1 case studies (anecdotes). Predatory journals and manufacturer-authored studies without independent replication are weighted down.
Product-specific evidence citations for this item are embedded in the analysis text on the "Analysis" tab. For the full framework and evidence hierarchy, see the methodology page.

Solgar Calcium Magnesium with Vitamin D3 150 Tablets is a product from Solgar, 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.
66/100 overall — Standard tier (50–69 band). Per-dimension breakdown: Manufacturing 78, Safety 72, Evidence 68, Formulation 65, Transparency 65, Sustainability 55. Scored as of 2026-08-24.
Solgar Cal/Mag/D3 tri-blend for bone-health support. Solgar's practitioner-grade manufacturing carries. Held below Verified by (1) calcium supplementation evidence for fracture prevention is mixed (Bolland 2015 meta-analysis); (2) no K2 co-formulation despite the D3 driving calcium mobilization — third-gen bone formulations add K2 for calcium partitioning to bone vs soft tissue; (3) calcium form (carbonate vs citrate) affects absorption + needs stomach acid for carbonate. Would move to Verified 70+ with K2 addition + citrate form disclosure.
Strongest: Manufacturing at 78/100 (third-party testing, GMP compliance, and facility audit status) and Safety at 72/100 (adverse-event profile, interaction risk, and dose ceiling). Weakest: Transparency at 65/100 (dose disclosure vs proprietary blends, and honesty of marketing claims) and Sustainability at 55/100 (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 Verified 70+ with K2 addition + citrate form disclosure.

Tier bands: Elite 85–100 (top-tier evidence + formulation + manufacturing), Verified 70–84 (strong on most dimensions), Standard 50–69 (solid but with weaknesses called out), Rejected 0–49 (specific failures documented). Rejected products remain listed with reasons. Full methodology at https://vyvata.com/pages/methodology.
