Fish oil and calcium
Fish oil and calcium are often taken together, and there's no documented interaction between them. Fish oil doesn't naturally supply calcium — that mineral comes from bones, not the extracted oil.
Yes — fish oil and calcium are commonly taken together, and there's no documented interaction between them. Fish oil doesn't naturally supply calcium: the mineral in fish comes from the bones, not the extracted oil, so a fish oil softgel and a calcium supplement cover entirely different nutrients.
Does fish oil have calcium in it?
No. Fish oil is the fat extracted and concentrated from fish tissue; calcium is concentrated in bone, which isn't part of that extraction. Canned fish eaten with the bones — like sardines or canned salmon — is a calcium source for that reason, per USDA FoodData Central, but that's a property of the whole food, not the oil pressed from it. Our panel lists fish oil concentrate, EPA, DHA and vitamin E — no calcium, and no other minerals.
What each actually is
Fish oil supplies EPA and DHA, two long-chain omega-3 fatty acids; our softgel provides 180 mg of EPA and 120 mg of DHA from 1,000 mg of fish oil concentrate. Calcium is a mineral, mostly stored in bone and teeth, with a separate, established role in the body. They're different nutrient categories that happen to both be common daily supplements, which is likely why they're often searched and taken together.
What actually matters if you're taking both
- Timing. Fish oil is commonly taken with meals. Calcium doesn't require a comparable timing rule tied to fish oil specifically — check the calcium product's own label for any of its own directions.
- Dose independence. The amount of calcium you take doesn't change how much EPA or DHA you absorb from fish oil, or the reverse.
- Checking for overlap. If you're taking a multivitamin or a bone-support product, check whether it already includes calcium or omega-3s before adding a separate bottle of either.
Questions people ask
Can I take fish oil with calcium?
Yes. There's no documented interaction between fish oil and calcium at typical supplement doses.
Can I take calcium and fish oil together, or should they be spaced apart?
They can be taken together — there's no research showing a need to space them apart. Following each product's own label directions is the only timing guidance that's actually been established for either one.
Does fish oil have calcium?
No. Fish oil concentrate is fat and omega-3 fatty acids; it doesn't contain calcium or other minerals unless a brand specifically adds them, which ours does not.

- Determinants of erythrocyte omega-3 fatty acid content in response to fish oil supplementation: a dose-response randomized controlled trial In 115 healthy adults, daily doses from 300 mg to 1,800 mg of EPA and DHA raised a blood marker called the omega-3 index in a dose-dependent way over about five months; the trial measured a blood biomarker, not a health outcome.
