Six-dimension breakdown
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 in How we scored this, above. 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.

What is NOW Foods Magnesium Citrate?
NOW Foods Magnesium Citrate is a product from NOW Foods, categorized under Vitamins & foundational micronutrients in the Supplements vertical. It is scored on the Vyvata Scoring Framework — an independent 6-dimension rubric applied uniformly to every product Vyvata lists.
How does NOW Foods Magnesium Citrate score on the Vyvata rubric?
70/100 overall — Verified tier (70–84 band). Per-dimension breakdown: Safety 85, Transparency 80, Evidence 70, Formulation 65, Manufacturing 65, Sustainability 55. Scored as of 2026-08-24.
Why did NOW Foods Magnesium Citrate score in the Verified tier?
Magnesium citrate at 133 mg elemental per cap — well-absorbed form (Walker et al. 2003 crossover showed citrate outperformed oxide). Dose is modest so several caps daily needed to hit RCT-typical 300-400 mg elemental. NOW GMP quality; clean single-ingredient label. Verified at the low end for standard form, standard dose, standard manufacturing.
What are the strongest and weakest aspects of this product?
Strongest: Safety at 85/100 (adverse-event profile, interaction risk, and dose ceiling) and Transparency at 80/100 (dose disclosure vs proprietary blends, and honesty of marketing claims). Weakest: Manufacturing at 65/100 (third-party testing, GMP compliance, and facility audit status) 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.
