Cod Liver Oil
Cod Liver Oil by GNC is a vitamin and mineral supplement containing 2 ingredients, primarily focused on Vitamin A and D intake. This product delivers Vitamin A at a clinical dose of 1250 IU, which is commonly associated with immune function and vision support. However, its Vitamin D3 content is 135 IU, which is considered underdosed compared to amounts commonly used in research for optimal bone health and immune support. With an N+ Score of 58 and an F grade, this product falls into the average tier, indicating a formulation with mixed dosing quality. While it provides a good source of Vitamin A, the low Vitamin D3 dosage limits its comprehensive benefits.
