Can I take omega-3 with vitamin D and multivitamin?

Yes, and the one sum a multivitamin makes necessary, vitamin D across two tubs against the upper level

Can I take omega-3 with vitamin D and a multivitamin is answered yes, and the trio contains one sum that a multivitamin makes necessary and one help that a fish oil makes possible. The sum: most multivitamins carry a vitamin D line, typically 10 micrograms in a basic one-a-day and up to 25 in a premium or a sports formula, so a reader who takes a separate vitamin D beside a multivitamin is taking vitamin D twice and adds the two, the total kept under the adult tolerable upper level of 100 micrograms a day, the vitamin D safety literature's figure, above which calcium can rise in the blood over months. The arithmetic is usually reassuring: the UK winter advice of 10 micrograms plus a multivitamin's 10 is 20, fine, and even a 25 microgram vitamin D beside a 25 microgram multivitamin is 50, half the level, but a reader on a high-dose 100 microgram vitamin D tablet, which some take through winter or on a GP's advice for deficiency, has reached the level before the multivitamin is added and either drops the multivitamin's contribution from the count by choosing one without vitamin D or drops the separate high dose to a lower one, the GP's deficiency dose being the one exception where a doctor's instruction overrides the sum for a defined period. The sum is done once, at the nutrient tables of both tubs, and rarely needs revisiting.

The help the fish oil gives, the multivitamin's minerals and vitamin A counted, the meal, and the trio filed

The help: vitamin D is fat-soluble and absorbs markedly better with fat, and so are the multivitamin's vitamin A, vitamin E and vitamin K, so a multivitamin and a separate vitamin D taken beside a fish oil softgel and a fatty meal deliver more of their fat-soluble vitamins than the same tablets with water on waking, the fat-soluble shelf's rule and the one interaction in the trio, running in the reader's favour, the fish oil supplying a gram of fat and the meal the rest. The multivitamin's minerals are counted, as on every multivitamin page here, against any separate mineral tub the reader takes, its 50 to 100mg of magnesium beside a bisglycinate, its 5 to 15mg of zinc beside a separate zinc against the 25mg level, its iron beside an iron tablet, the nutrient table read once. Vitamin A is the multivitamin's other fat-soluble line and the reason the fish oil's type matters: a body-oil fish oil carries no vitamin A and sits beside a multivitamin's vitamin A without a sum, while a cod liver oil carries hundreds of micrograms of preformed vitamin A a capsule and beside a multivitamin's own can approach the 3000 microgram upper level, so a reader on a multivitamin chooses a body oil, the fish oil and vitamins page's one real caution. The meal: all three at the evening meal for most lifters, the fish oil for its fat, the vitamin D and the multivitamin for the fat the fish oil and the meal supply, with the honest note that a multivitamin's water-soluble vitamins are indifferent to the hour and its minerals sit hours from any fasted morning medicine, so the evening suits the whole tablet. The trio filed: omega-3 with vitamin D and a multivitamin is fine, the vitamin D summed across the two tubs under 100 micrograms, the fat-soluble vitamins helped by the fish oil's fat, the multivitamin's minerals counted against separate tubs and its vitamin A safe beside a body oil, with the worked example being the body oil that carries the fat and no vitamin A, one softgel at 17p, £14.99 for 90.

The verdict, one sum, one help, and a body oil that keeps the sum short

Can I take omega-3 with vitamin D and a multivitamin: yes, with one sum, the multivitamin's own 10 to 25 micrograms of vitamin D added to the separate vitamin D and the total kept under the 100 microgram adult upper level, which the winter's 10 micrograms plus a multivitamin's 10 clears easily and a high-dose tablet plus a multivitamin does not, and one help, the fish oil's fat and a fatty meal carrying vitamin D and the multivitamin's A, E and K, with the multivitamin's minerals counted against any separate tub and a body-oil fish oil chosen so that its vitamin A raises no second sum. The body oil that carries the fat: Futuro Labs Omega 3 Fish Oil, one softgel with food, 180mg EPA and 120mg DHA, 90 for £14.99 at 17p a day.

Questions people also ask

Can I take a multivitamin and a separate vitamin D with fish oil?

Yes, with the vitamin D added across the two tubs and kept under the 100 microgram adult upper level, the multivitamin's 10 to 25 micrograms plus a winter 10 being comfortably under, and all three taken at a fatty meal where the fish oil's fat helps the fat-soluble vitamins absorb.

How much vitamin D is too much when a multivitamin also has it?

Over 100 micrograms a day in total for an adult, the tolerable upper level above which blood calcium can rise over months, so a high-dose 100 microgram tablet beside a multivitamin's own is over, while the common 10 to 25 microgram doses sum to a fraction of the level.

Does fish oil help a multivitamin work?

It helps the fat-soluble part: vitamin A, D, E and K in a multivitamin absorb markedly better with fat, which a fish oil softgel and a fatty meal supply, while the water-soluble vitamins and the minerals absorb on their own routes regardless.

Should I worry about vitamin A when taking fish oil with a multivitamin?

Only with a cod liver oil, which carries hundreds of micrograms of preformed vitamin A a capsule and beside a multivitamin's own can approach the 3000 microgram upper level; a body-oil fish oil carries no vitamin A and raises no sum.

What is the best time to take omega-3, vitamin D and a multivitamin?

The evening meal for most lifters: the fish oil wants fat, the vitamin D and the multivitamin's fat-soluble vitamins want the same fat, the multivitamin's minerals sit hours from any fasted morning medicine, and one plate anchors the whole trio.
