Vitamin B-1 100 mg
Rugby Vitamin B-1 100 mg is a single vitamin and mineral supplement providing Thiamine (Vitamin B1). This product delivers 100mg of Thiamine, which is considered a clinically studied dose, alongside 40mg of Calcium, which research suggests is an underdosed amount. With a total of two ingredients and 100% label transparency, the product achieves an N+ Score of 55, earning an 'F' grade, indicating limitations in its formula completeness and overall ingredient adequacy. While it provides a robust dose of Thiamine, the minimal calcium content means it is not a significant source for bone health. This supplement may appeal to individuals specifically looking to boost their Thiamine intake.
