Nature's Bounty CoQ10 200mg Dietary Supplement - 30 Capsules

Six-dimension breakdown

Why this scored 65/100

Nature's Bounty is a mainstream US supplement brand owned by Bountiful Company with mass-retail distribution. This SKU is a single-ingredient CoQ10 at a disclosed 200 mg per capsule dose taken once daily. CoQ10 has one of the stronger cardiovascular-health evidence bases in the supplement category: the Q-SYMBIO trial (Mortensen 2014) showed CoQ10 300 mg/day reduced major cardiovascular events in chronic heart failure patients, and multiple meta-analyses support use in statin-associated myalgia (Fedacko 2013, Banach 2015). 200 mg is a reasonable daily dose — the studied range is 100-400 mg with mid-range trials at 200 mg showing measurable serum-level increases. Ubiquinone (oxidized) vs ubiquinol (reduced) form matters somewhat — ubiquinol has 2-3x better bioavailability in older adults — but Nature's Bounty typically uses ubiquinone which is fine for most users. Standard-tier entry. USP verification and disclosed form (ubiquinone vs ubiquinol) would push toward Verified.

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.
