Can you take fish oil with other vitamins?

Yes with any of them, and the card vitamin by vitamin, the water-soluble ones first

Can you take fish oil with other vitamins, and the variant asking about any other vitamins, is answered yes with all of them, because a fat binds nothing and is bound by nothing, and a card vitamin by vitamin puts the yes beside each with the one note that applies. The water-soluble vitamins first, since they are the simplest. The B group, B1 through B12 and folate: fine, absorbed on their own water-soluble routes in the small intestine, unaffected by a fat in the same meal and unaffecting it, a B complex or a B12 tablet sitting beside a softgel without a thought. Vitamin C: fine, the acidity idea being irrelevant to a fat absorbed in the intestine rather than the stomach, and the antioxidant idea being a chemistry-class fancy with no interaction in a gut, a vitamin C tablet and a softgel at the same meal doing nothing to each other. The fat-soluble vitamins next, where the yes becomes a better together. Vitamin D: absorbed 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 dissolved 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 the rest, the fat-soluble shelf's rule and the three-tub page's helpful pair, the vitamin D dosed by the UK winter's 10 micrograms. Vitamin E: already in the softgel, added to nearly every fish oil as an antioxidant to slow the oil's oxidation and listed as tocopherols in the ingredients, so a separate vitamin E is not needed for the oil's sake and is fine beside it if taken for its own, the folklore that the two should be separated being the reverse of the practice.

Vitamins A and K with their notes, a multivitamin, and the card filed

Vitamin A: fine beside a body-oil fish oil, which carries no vitamin A, and a sum beside a cod liver oil, which carries hundreds of micrograms of preformed vitamin A a capsule, so a reader taking a separate vitamin A supplement or a multivitamin with a vitamin A line adds it across labels against the adult upper level of 3000 micrograms a day if the fish oil is a liver oil and adds nothing if it is a body oil, the one real vitamin caution on the fish oil shelf and the reason every worked example here is a body oil, with pregnancy avoiding liver oils altogether. Vitamin K: fine beside a fish oil, the two interacting in no direction, with the note that a reader on warfarin has a vitamin K conversation with their prescriber that belongs to the vitamin K, which opposes the medicine, rather than to the fish oil, whose own warfarin note is the modest antiplatelet effect at gram-and-above doses, a different mechanism, so a warfarin user asks about both and blames neither on the other. A multivitamin: fine, its water-soluble vitamins on their own routes and its fat-soluble A, D, E and K absorbing better beside the fish oil and a meal, with two sums, its vitamin D added to any separate vitamin D and kept under the 100 microgram upper level, and its vitamin A beside a body oil raising no sum and beside a cod liver oil raising one, the multivitamin page's arithmetic. The meal that suits the whole card is the evening one for most readers, the fish oil wanting fat, the fat-soluble vitamins wanting the same fat, and the water-soluble ones indifferent. The card filed: the B group and vitamin C fine on their own routes, vitamin D better together, vitamin E already in the softgel, vitamin A fine beside a body oil and summed beside a liver oil, vitamin K fine with a warfarin note that is the K's, and a multivitamin fine with its D and A counted, no vitamin conflicting with a fat, and the worked example being a body oil that sits beside any vitamin and carries the fat-soluble ones, one softgel at 17p, £14.99 for 90.

The verdict, yes to every vitamin, better to the fat-soluble ones, and two notes that belong to other molecules

Can you take fish oil with other vitamins: yes with all of them, the B group and vitamin C fine on their own water-soluble routes, vitamin D better together because the fish oil's fat and the meal carry it, vitamin E already in the softgel as its antioxidant, vitamin A fine beside a body oil and summed across labels beside a cod liver oil against the 3000 microgram upper level, vitamin K fine with the warfarin note belonging to the vitamin K rather than the fish oil, and a multivitamin fine with its fat-soluble vitamins absorbing better beside the oil and its vitamin D and A counted, no vitamin conflicting with a fat and the evening meal suiting the whole card. A body oil that sits beside any vitamin: Futuro Labs Omega 3 Fish Oil, one softgel with food, 180mg EPA and 120mg DHA, no vitamin A, 90 for £14.99 at 17p a day.

What to check on the label

Questions people also ask

Which vitamins should not be taken with fish oil?

None: a fat binds nothing and is bound by nothing, the water-soluble B group and vitamin C absorb on their own routes, the fat-soluble A, D, E and K absorb better beside the fish oil's fat, and the only notes are a vitamin A sum beside a cod liver oil and a warfarin conversation that belongs to vitamin K itself.

Can I take vitamin C with fish oil?

Yes: vitamin C is water-soluble and absorbed on its own route, the acidity idea being irrelevant to a fat absorbed in the intestine rather than the stomach, so a vitamin C tablet and a softgel at the same meal do nothing to each other.

Is it better to take vitamin D with fish oil?

Yes: 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 dissolved into the meal's fat, so the softgel supplies part of what the vitamin D needs and the pair goes with the evening meal.

Do I need to take vitamin E with fish oil?

Not for the oil's sake: nearly every fish oil already contains vitamin E as tocopherols, added as an antioxidant to slow oxidation, so a separate vitamin E is unnecessary for the oil and fine beside it if taken for its own reasons.

Can I take a multivitamin and fish oil together?

Yes, at the same fatty meal, where the multivitamin's fat-soluble vitamins absorb better beside the oil, with two sums done once: its vitamin D added to any separate vitamin D under the 100 microgram upper level, and its vitamin A beside a body oil raising no sum and beside a cod liver oil raising one.
