Can you take omega-3 with magnesium and Vitamin D?

Yes, and the one stack whose interactions run in the reader's favour, pair by pair

Can you take omega-3 with magnesium and vitamin D is answered yes, and it is worth saying why this stack is different from most, because most supplement pairings interact not at all and this one interacts in the reader's favour, pair by pair. Fish oil and vitamin D: 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 the fat-soluble rule, and a fish oil softgel is itself a gram of fat taken with the meal, so the omega-3 supplies part of the fat the vitamin D needs and the meal supplies the rest, a genuine, if small, help. Magnesium and vitamin D: the enzymes that convert vitamin D through its liver and kidney steps into its active form are magnesium-dependent, so a magnesium shortfall impairs vitamin D activation and a vitamin D supplement in a magnesium-short reader does less than it should, while vitamin D in turn supports the active route of intestinal magnesium absorption, the absorption-levers page's third lever, so adequacy in each supports the other, a cofactor relationship the folklore overstates into a requirement and the physiology supports as a help. Omega-3 and magnesium: no interaction in either direction, a fat and a mineral on different routes, the evening-pair page's finding. Three pairs, two helpful and one inert, which is as good as a stack gets.

The evening meal, the three audits, the pence, and the stack filed

The evening meal is the place for all three, for three reasons that coincide: the fish oil wants the fattiest meal for absorption and fewer burps, the vitamin D wants fat for the same reason, and the magnesium wants an anchor and sits gentler with food, so one softgel, two capsules and a vitamin D drop or tablet go beside the plate, hours from any fasted morning medicine, with a reader who prefers a morning vitamin D taking it with a breakfast that contains fat and losing nothing. The three audits are separate, and a reader may need three, two, one or none. Omega-3: for a reader who eats fewer than the two portions of fish a week UK advice sets, one oily, and so misses the 250mg of EPA and DHA the heart claim needs, one standard softgel supplying it. Magnesium: for a reader whose training plate runs light in greens, nuts, seeds, legumes and wholegrains, on a cut or a rice-and-chicken bulk, closing a shortfall at 300mg elemental as bisglycinate. Vitamin D: for everyone in the UK from October to March, on the government's advice that adults consider 10 micrograms a day through the winter when the sun is too low for skin synthesis, and year-round for people with dark skin, who cover up or who rarely go outside, with the upper level of 100 micrograms a day a ceiling few approach, the vitamin D pages' standing advice and the one supplement on this site recommended by season rather than by audit. The pence: the omega-3 benchmark at 17p, the magnesium benchmark at 22p and a 10 microgram vitamin D at 2 to 3p make the stack about 42p a day, the cheapest three-tub habit a lifter is likely to keep. The stack filed: omega-3, magnesium and vitamin D together, the fat carrying the vitamin D, the magnesium serving as its activating cofactor, the omega-3 and magnesium inert, all at the evening meal, each by its own audit and the vitamin D by the season, the worked example being two of the three at one meal with a vitamin D beside them through the winter.

The verdict, a stack that is inert in one pair and helpful in two

Can you take omega-3 with magnesium and vitamin D: yes, and this is the one stack whose interactions run in the reader's favour, vitamin D absorbing better with the fat a fish oil softgel and a fatty meal supply, magnesium serving as a cofactor in the enzymes that activate vitamin D while vitamin D supports magnesium's absorption, and omega-3 and magnesium interacting in no direction, all three taken at the evening meal for about 42p a day at the benchmarks, with omega-3 by the oily-fish audit, magnesium by the plate audit and vitamin D by the UK winter's advice. Two of the three at one meal: Futuro Labs Omega 3 Fish Oil, one softgel at 17p, and Futuro Labs Magnesium Glycinate, two capsules at 22p, with a 10 microgram vitamin D beside them from October to March.

Questions people also ask

Is it good to take fish oil, magnesium and vitamin D together?

Yes, and better than most stacks: vitamin D absorbs better with the fat a fish oil softgel and a fatty meal supply, magnesium is a cofactor in the enzymes that activate vitamin D, and omega-3 and magnesium interact in no direction, so the three go at the evening meal and help rather than hinder each other.

Does magnesium help vitamin D work?

Yes: the liver and kidney enzymes that convert vitamin D to its active form are magnesium-dependent, so a magnesium shortfall impairs activation and a vitamin D supplement does less in a magnesium-short reader, while vitamin D in turn supports the active route of magnesium absorption, adequacy in each supporting the other.

Should I take vitamin D with fish oil?

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 two together at the evening meal is the fat-soluble rule applied twice.

How much vitamin D should a lifter take with omega-3 and magnesium?

The UK advice: 10 micrograms a day from October to March for all adults, when the sun is too low for skin synthesis, and year-round for people with dark skin, who cover up or who rarely go outside, with 100 micrograms a day the upper level, the one supplement here taken by season rather than by audit.

How much does the omega-3, magnesium and vitamin D stack cost?

About 42p a day at the benchmarks: 17p for a standard fish oil softgel, 22p for two bisglycinate capsules and 2 to 3p for a 10 microgram vitamin D, the cheapest three-tub habit a lifter is likely to keep.
