Zinc Sulfate 220 mg
Rugby Zinc Sulfate 220 mg is categorized as a mineral supplement, primarily featuring Zinc. Each serving provides 50mg of Zinc, which is considered a clinically studied dose, and 95mg of Calcium, which research suggests is significantly underdosed. With only two ingredients and 100% label transparency, the product receives an N+ Score of 55, resulting in an 'F' grade, highlighting concerns regarding its overall formula completeness and ingredient adequacy. While the zinc dosage may support various bodily functions, the minimal calcium contribution means it is not a comprehensive bone health supplement. This product might be considered by those specifically looking to supplement zinc at a higher dose.
