Is this real vitamin A and D, or the synthetic kind?
Our cod liver oil supplement, as the name implies, comes directly from the liver of Icelandic codfishes and is a specific type of fish oil. It delivers omega-3 fatty acids plus naturally occurring vitamins A and D, with no synthetic or adulterated forms of these vitamins, maintaining nature's intended 10:1 ratio.
- Adults who want naturally occurring vitamin A and D from cod liver oil rather than synthetic forms
- Adults who want omega-3 fatty acids and vitamins A and D in one softgel
- Practitioners who prefer cod liver oil, with nature's 10:1 ratio kept intact, on a label
- As a dietary supplement, adults take 1 softgel capsule, 1 to 3 times daily with meals, or as directed by your health care professional.
- Comes directly from the liver of Icelandic codfishes. A specific type of fish oil, 415 mg per softgel, delivering omega-3 fatty acids plus naturally occurring vitamins A and D.
- Naturally occurring vitamin A and D, in nature's intended 10:1 ratio. 375 mcg (1,250 IU) of vitamin A and 3.4 mcg (135 IU) of vitamin D per softgel, both from the cod liver oil. The product contains no synthetic or adulterated forms of these vitamins.
- Supports natural retinol and vitamin D intake. The manufacturer's own language for what the formula is for, alongside immune health and heart and liver function.
- Omega-3 fatty acids come with it. 37 mg EPA, 36 mg DHA, and 17 mg of other omega-3 fatty acids per softgel, as printed on the panel.
- Supports immune health, heart and liver function. That is Formula IQ's stated framing for the formula; the nutrient-level research behind vitamins A and D is in the drop-down.

The research behind the ingredients
Published research on the ingredients in this product, for education. These studies were not conducted on this product.
Cod liver oil (EPA and DHA omega-3 fatty acids)
The influence of dietary and supplemental omega-3 fatty acids on the omega-3 index: A scoping review
Frontiers in Nutrition · 2023 · systematic review · n=58 original research articles
Reviewing 58 studies, the authors report that about 1,000-1,500 mg/day of combined EPA and DHA for at least 12 weeks is the intake most consistently associated with reaching an omega-3 index of 8% or more, and that triglyceride-form oils are absorbed better than ethyl esters.
Naturally occurring vitamin D in cod liver oil
Vitamin D daily dose review, 2024
Nutrients · 2024 · mechanistic review
Reviewing supplementation trials, the authors report that 2000 IU (50 µg) of vitamin D daily keeps serum 25-hydroxyvitamin D above 50 nmol/L in more than 99% of adults and above 75 nmol/L in more than 90%, without safety signals in multi-year randomized trials.
Naturally occurring vitamin A (retinol) in cod liver oil
Vitamin A forms and sources review, 2021
Nutrients · 2021 · mechanistic review
This review reports that liver carries tens of milligrams of retinol and retinyl esters per 100 g, that retinyl esters from animal foods are almost completely absorbed when eaten with fat, and that vitamin A is required for rhodopsin formation, gene regulation, immune function and cell differentiation.
Evidence note: Strong at the nutrient level: vitamin A, vitamin D and long-chain EPA/DHA each have substantial randomized human evidence, and FIQ's panel now publishes the per-softgel amounts (375 mcg vitamin A, 3.4 mcg vitamin D, 37 mg EPA, 36 mg DHA), so a serving can be compared directly against those trial intakes. The trials studied the nutrients rather than this particular oil.
