Solgar Calcium Citrate with Vitamin D3 120 Tablets

Six-dimension breakdown

Why this scored 70/100

Solgar Calcium Citrate with Vitamin D3 — same brand quality context as the Solgar K2 product scored above. Solgar is a premium US vitamin brand (est. 1947, cGMP-certified, amber-glass light-protective bottles, single-ingredient discipline). Calcium citrate is the better-absorbed form (see Citracal note); Solgar's version pairs it with Vitamin D3 at conservative maintenance dosing. Solgar generally scores well in ConsumerLab spot testing for label accuracy and does not use proprietary blends. Verified tier for the combination of premium brand track record, well-formulated calcium citrate + D3, and honest single-purpose formulation. Held out of Elite by (1) same absence of publicly-posted per-lot COAs as noted before, (2) no K2 pairing, and (3) evidence for calcium supplementation on hard outcomes has softened over the past decade (Bolland 2010 CV signal, Bolland 2015 meta-analysis on fracture reduction more modest than earlier estimates).

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.
