Can I take fish oil with vitamin D?

Vitamin D with fish oil, the fat-soluble shelf at its best, and why no vitamin conflicts with a fat

Can I take fish oil with vitamin D is answered yes and better together, and the variants asking which vitamins should not be taken with fish oil are answered none, with one real caution that is not what the folklore expects. Vitamin D with fish oil: vitamin D is fat-soluble and its absorption from a supplement is markedly better with a fat-containing meal than fasted, the vitamin D absorption literature's finding, and a fish oil softgel is a gram of fat that dissolves into the meal's fat and the bile's micelles, so the softgel supplies part of the fat the vitamin D needs and the meal supplies the rest, the pair going with the evening meal and helping each other, the three-tub page's finding that this is the one stack whose interactions run in the reader's favour, with the vitamin D dosed by the UK winter advice of 10 micrograms a day from October to March and year-round for those who get little sun. No vitamin conflicts with a fish oil: omega-3 is a fat that binds nothing and is bound by nothing, the water-soluble vitamins, B and C, absorbing on their own routes without noticing it, and the fat-soluble vitamins, A, D, E and K, absorbing better beside it, vitamin E in particular being added to nearly every fish oil as an antioxidant to slow the oil's oxidation and appearing on the ingredients list as tocopherols, so the folklore that vitamin E and fish oil should be separated is the reverse of the practice, the not-mix page's retired conflict, and the answer to what vitamins cannot be taken with fish oil is, for a body oil, none at all.

The one real caution, vitamin A and cod liver oil, the vitamin K note, and the pair filed

The one real caution is vitamin A, and it belongs to a particular fish oil. A body-oil fish oil, from anchovy, sardine and mackerel, carries no vitamin A and raises no question. A cod liver oil is a liver oil, and livers store vitamin A, so a cod liver oil capsule or teaspoon carries hundreds of micrograms of preformed vitamin A, retinol, alongside its omega-3 and its own vitamin D, and preformed vitamin A has an adult upper level of 3000 micrograms a day above which liver damage and, in pregnancy, birth defects become risks, the vitamin A advice's figures, with pregnancy advice being to avoid liver oils and liver altogether. A cod liver oil stacked with a multivitamin that carries its own vitamin A, or with a separate vitamin A supplement, or taken at several capsules a day, is the one combination in which a fish oil can push a vitamin over its limit, and the stack's arithmetic is read across the two labels, the retinol from each added, with a reader who takes a multivitamin choosing a body-oil fish oil to avoid the sum entirely and a pregnant reader choosing a body oil without exception. The vitamin K note: vitamin K matters to warfarin users because it opposes the medicine, and the caution belongs to a vitamin K supplement or a multivitamin with a vitamin K line rather than to the fish oil, whose own note for warfarin users is the modest antiplatelet effect at gram-and-above doses, a prescriber's conversation and a different mechanism, so a warfarin user asks about both and blames neither on the other. The pair filed: fish oil with vitamin D is the fat-soluble shelf at its best, no vitamin conflicts with a fish oil, vitamin E is in the softgel already, the one caution is a cod liver oil's vitamin A stacked with a multivitamin or a vitamin A supplement against the 3000 microgram upper level, and vitamin K's caution belongs to warfarin and to a vitamin K supplement, with the worked example being a body-oil fish oil with no vitamin A beside the vitamin D, one softgel at 17p, £14.99 for 90.

The verdict, the best fat-soluble pairing, and a caution that belongs to a liver oil

Can I take fish oil with vitamin D: yes and better together, vitamin D absorbing markedly better with the fat a fish oil softgel and a fatty meal supply, with no vitamin conflicting with a body-oil fish oil, a fat binding nothing and vitamin E being added to the softgel as its antioxidant, and the one real caution being vitamin A, a cod liver oil carrying hundreds of micrograms of preformed vitamin A a capsule that, stacked with a multivitamin or a vitamin A supplement, can approach the 3000 microgram adult upper level, pregnancy advice being to avoid liver oils, while vitamin K's caution belongs to warfarin and to a vitamin K supplement rather than to the fish oil. A body-oil fish oil with no vitamin A: Futuro Labs Omega 3 Fish Oil, one softgel with food, 180mg EPA and 120mg DHA, 90 for £14.99 at 17p a day, beside the vitamin D.

What to check on the label

Questions people also ask

Is it okay to take vitamin D with fish oil?

Yes, and it helps: vitamin D is fat-soluble and absorbs markedly better with a fat-containing meal than fasted, and a fish oil softgel is a gram of fat taken with the meal, so the pair goes with dinner and the softgel supplies part of the fat the vitamin D needs.

What vitamins should not be taken with fish oil?

None with a body-oil fish oil: a fat binds nothing, the water-soluble vitamins absorb on their own routes and the fat-soluble ones absorb better beside it, with vitamin E already added to the softgel as an antioxidant.

Can you take too much vitamin A with fish oil?

Only with a cod liver oil: a liver oil carries hundreds of micrograms of preformed vitamin A a capsule, and stacked with a multivitamin or a vitamin A supplement it can approach the 3000 microgram adult upper level, so both labels are read together, a body oil carries none, and pregnancy avoids liver oils altogether.

Should I take vitamin E with fish oil?

You already do: nearly every fish oil lists tocopherols, which is vitamin E added as an antioxidant to slow the oil's oxidation, so the folklore that the two should be separated is the reverse of the practice.

Does fish oil interact with vitamin K or warfarin?

The vitamin K caution for warfarin users belongs to a vitamin K supplement or a multivitamin's vitamin K line, which opposes the medicine; the fish oil's own warfarin note is its modest antiplatelet effect at gram-and-above doses, a different mechanism and a prescriber's conversation.
