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.
May improve sleep quality, especially in older adults and those with low magnesium status.
60% of body magnesium is stored in bone. Essential for bone mineralization.
May reduce muscle cramps and support post-exercise recovery.
Essential for red blood cell formation. Deficiency causes megaloblastic anemia, confirmed by decades of clinical evidence.
Involved in myelin synthesis and nerve function. Adequate B12 status supports neurological health, particularly in older adults and vegans.
Cofactor in energy production pathways, but supplementation only helps if deficient.

Alternatives are selected from the same category (Vitamin D) with a higher overall score. This is not a recommendation — always verify ingredients and dosages match your needs.
At 400mg/day (far above RDA of 1.3mg), riboflavin may reduce migraine frequency. Effect is dose-dependent and not expected at typical supplement doses.
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.
