If you're looking for immune and bone support from **Vitamin A** and **Vitamin D**, this cod liver oil delivers on the first but falls short on the second. Three softgels daily give you 1,125mcg of Vitamin A — well within the 700–1,500mcg clinical range — but only 405 IU of **Vitamin D**, less than half the 1,000 IU minimum supported by current research.

Both vitamins come in well-absorbed forms: Vitamin D as D3 and Vitamin A as a preformed source. The cod liver oil base also provides some omega-3 fatty acids, though no EPA or DHA amounts appear on the label, so you can't gauge your omega-3 intake from this product.

The main gap is the Vitamin D dose. At 405 IU across your full daily serving, you're unlikely to move the needle on D levels. This works as a Vitamin A source with modest secondary benefits, but if Vitamin D is your primary goal, you'll need to supplement it separately.
