Why this scored 50/100
Evergreen Apothecary Vitamin C Support Tincture is positioned as vitamin C support from plants naturally containing ascorbic acid (rose hips, likely acerola, camu camu, or similar). The core evidence issue: vitamin C content in an alcohol-based tincture is generally very low relative to food-form or supplement-form vitamin C, and vitamin C is water-soluble and heat/oxidation-sensitive so tincture processing degrades ascorbic acid content. Rose hips are indeed vitamin C-rich in fresh form (0.5-1.5 g per 100 g fresh weight) but the vitamin C content in a preserved tincture is typically a small fraction of what could be delivered by a food-form rose hip preparation, ascorbic acid powder, or standard vitamin C supplement. A typical tincture dropperful may deliver <10 mg vitamin C vs 500-1000 mg from a standard supplement. Marketing this as meaningful vitamin C support sets an expectation the delivery format cannot meet. Not a safety concern; a dose-vs-marketing mismatch.

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.
