Same category, higher SupplementScore. Based on dosage transparency, label cleanliness, and formula quality.
The research summaries below are about the ingredients in general, drawn from published studies that often use different doses, forms, and populations than this product. A "strong" evidence rating for an ingredient does not mean this product will produce that effect — studied doses may be significantly higher or lower than what is contained here. Always verify doses against the Supplement Facts table above.
