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.
Essential for rhodopsin production in the retina. Deficiency causes night blindness — one of the earliest recognized nutritional deficiencies.
Critical role in maintaining mucosal barriers and immune cell function.
Essential for calcium absorption. Deficiency leads to rickets in children and osteomalacia in adults — a well-established causal relationship.
May reduce risk of respiratory infections. Active area of research.
Some association between low vitamin D levels and depression, but evidence is inconsistent.
May support cardiovascular health by influencing triglyceride levels. Effect is dose-dependent (typically studied at 1-4g EPA+DHA/day).
