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.
Zinc is a cofactor for over 300 enzymes involved in immune cell development and function. Supplementation may reduce duration of common cold symptoms, particularly as lozenges. Essential for maintaining immune barrier integrity.
Essential for skin integrity and wound repair processes.
Primary structural component of bones. Adequate lifelong intake, combined with vitamin D, helps prevent osteoporosis — supported by extensive clinical evidence.
Essential for muscle contraction through calcium signaling.
Involved in neurotransmitter synthesis including serotonin and dopamine. Cofactor for over 100 enzyme reactions.
B6 is a cofactor in the transsulfuration pathway, converting homocysteine to cysteine. This is a separate pathway from the B12/folate remethylation route.

Alternatives are selected from the same category (Vitamin C) with a higher overall score. This is not a recommendation — always verify ingredients and dosages match your needs.
Supports immune cell function. Regular supplementation may modestly reduce cold duration, but does not prevent colds.
Potent water-soluble antioxidant that protects cells from oxidative damage.
Essential cofactor for enzymes involved in collagen production.
Protects polyunsaturated fatty acids in cell membranes from oxidation.
May help protect skin from UV damage when combined with vitamin C.
Limited evidence. May help in cases of biotin deficiency but most people get adequate amounts from diet.
Essential cofactor for carboxylases involved in gluconeogenesis, fatty acid synthesis, and amino acid catabolism.
Some RCTs show improved skin hydration after 8-12 weeks at 2.5-10g/day of hydrolyzed collagen peptides. Results vary by collagen type and source.
May reduce joint pain in athletes and osteoarthritis patients, particularly type II collagen.
