Solgar Calcium Citrate with Vitamin D3 240 Tablets

Six-dimension breakdown

Why this scored 66/100

Solgar Calcium Citrate with Vitamin D3 pairs calcium citrate (the better-absorbed calcium salt, particularly for people with low stomach acid, elderly adults, and PPI users) with vitamin D3 (cholecalciferol, the more effective vitamin D form for raising 25-OH-D levels vs. D2). The combination is evidence-aligned: vitamin D is required for calcium absorption in the intestine, and the paired product simplifies coverage of both micronutrients. Where the product is genuinely useful: postmenopausal women, older adults at fracture risk, people on chronic PPI or H2-blocker therapy (which impairs calcium carbonate but not calcium citrate absorption), people with low dietary calcium intake (<600-800 mg/day from food), and people with limited sun exposure. Where the safety score is capped: recent meta-analyses of calcium supplementation without vitamin D have raised concerns about cardiovascular event risk (Bolland 2010, though disputed), and calcium supplementation should ideally be food-first and only added to reach the ~1000-1200 mg/day target rather than layered on top of an already-adequate dietary intake. Solgar manufacturing is solid (GMP-certified, kosher-parve, decades-established); no per-lot third-party COAs routinely published. Solid Standard-tier bone-health supplement for the populations who benefit; oversupplementation is not benign.

Evidence & sources

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.

How to read the Evidence dimension

• 80–100: Multiple double-blind RCTs in indexed journals directly testing this product OR the exact ingredients at the exact dose.
• 60–79: Single double-blind RCT + supporting ingredient literature at the studied dose.
• 40–59: Open-label trials + ingredient literature; no product-specific double-blind evidence.
• 20–39: Ingredient literature only; no product-specific trials or trials in predatory venues.
• 0–19: No credible evidence base or unverifiable claims.
