Can You Take Curcumin With Magnesium?

Quick answer

No source we read names an interaction between magnesium and curcumin or turmeric, and we found no study of the two together. Magnesium binds some medicines in the gut, while turmeric has been linked to liver injury. Magnesium from supplements is limited to 350 mg a day, and no limit is set for turmeric.^1,2,3,4

Key facts

NIH's magnesium fact sheets do not mention turmeric or curcumin, and NCCIH's turmeric page does not mention magnesium.^1,2,4
Curcumin absorption depends on the product. After 2 g of plain curcumin, blood levels were undetectable or very low, while adding 20 mg of piperine raised bioavailability by 2,000%.⁵
Magnesium absorption depends on the amount taken. In one study the share absorbed fell from 65% to 11% as the amount rose, although the total absorbed still went up.⁶
A 2017 review lists oxalate among the things that lower magnesium uptake, and a 4-week study found that turmeric supplements raised urinary oxalate. No study has measured magnesium uptake with turmeric.^7,8
The main magnesium cautions concern the kidneys and medicines it binds in the gut. The main turmeric cautions concern the liver, the gallbladder and bleeding.^1,2,3

What is known about the two together

Nothing we read documents a problem with taking the two, and nothing shows a reason to take them as a pair. NIH's two magnesium fact sheets contain neither word, turmeric or curcumin, NCCIH's turmeric page never names magnesium, and a PubMed search on 2026-10-07 found no human study that gave people both.^1,2,4

They are different kinds of substance. Magnesium is a mineral the body needs, with recommended daily amounts of 310 to 420 mg for adults. Turmeric is the root of a ginger-family plant, and curcumin, its best-known compound, has no recommended amount at all.^2,4

What each has been studied for

Both have a muscle-related finding, but the two ask different questions. Magnesium's is a nutrient role in muscle and nerve function, and turmeric's is soreness in the days after hard exercise. Neither the trials behind them nor the reviews pooled them with the other ingredient.^9,10

Contributes to normal muscle and nerve function*^1,9,11

Moderate evidence

A long-established role of the mineral, described by NIH and included in the EU list of permitted nutrient-function statements. It does not mean extra magnesium improves performance in people who already get enough: a meta-analysis of 14 trials found no significant gains in muscle strength or power, with benefits appearing only in groups likely to be short of magnesium, such as older adults.

Amount studied: Recommended daily intake from food and supplements

May modestly reduce muscle soreness in the days after hard exercise*^10,12,13,14

Early evidence

Three meta-analyses of small randomized trials found lower soreness scores, and lower creatine kinase, a marker of muscle damage, with curcumin than with placebo after hard or unaccustomed exercise. The largest, 14 studies with 349 people, saw the clearest difference 4 days after exercise and with more than a week of use. The pooled differences in soreness were about half a point, and a 2024 meta-analysis of 16 papers found no statistically significant effect at any time point. The trials used many different formulations and doses.

Amount studied: 150 mg to 4 g of curcumin a day in different formulations, from a single dose to several weeks

NCCIH says there is not enough evidence to conclude that turmeric or curcumin is beneficial for any health purpose.²

Absorption and timing

Neither source suggests that one changes how the body absorbs the other. The one mineral study of turmeric looked at iron, not magnesium: 0.5 g of turmeric powder in a rice meal did not change iron absorption in 10 young women.¹⁵

There is one overlap worth knowing, though it is untested. The 2017 review lists oxalate among the things in a meal that lower magnesium uptake, and 4 weeks of turmeric supplements raised urinary oxalate in healthy adults. Whether that matters at supplement amounts is unknown, because no study measured magnesium uptake with turmeric.^7,8

In a one-week pilot study of eight adults under medical care, urine magnesium rose by 33.6 mg a day in those who took magnesium with meals and by 21.8 mg in those who took it fasting, a rough sign of more absorption with meals.¹⁶

Memory trials gave curcumin once a day as a solid lipid product, or twice a day in the 18-month trial. No study we found compared morning with evening doses, or taking curcumin with and without food.^17,18

So no source gives a reason to keep them apart. What the studies show moving blood levels is the product for curcumin, with levels varying many times over between formulations, and the dose and a person's own status for magnesium.^7,19,20

Amounts and limits

Limits and studied amounts for adults^{2,4,10,17,21,22,23}
	Magnesium	Turmeric or curcumin
Recommended daily amount	310 to 320 mg for women and 400 to 420 mg for men, from all sources	None
Upper limit	350 mg a day from supplements and medicines (US); 250 mg a day from supplements, water and fortified foods (EU)	None set; for curcumin used as a food color, EFSA applies 3 mg per kg of body weight a day, about 210 mg for a 70 kg adult
Amounts in trials	197 to 994 mg of magnesium a day	80 mg of curcumin a day in an absorption-enhanced form, up to 4 g a day
Our product, at the label's daily amount	Magnesium Glycinate, 275 mg	No turmeric product

The two cannot add up toward one shared limit, because they have no nutrient in common. The 350 mg magnesium limit counts magnesium only, and the EFSA figure belongs to curcumin used as a food color, not to supplements.^4,23

What's in ours

What’s in ours

Magnesium Glycinate: Magnesium, 275 mg per serving, from the label
Men's Multi: Magnesium, 50 mg per serving, from the label
Creatine + Electrolytes: Magnesium, 60 mg per serving, from the label

None of our products contains turmeric or curcumin, so no overlap note applies. Our Magnesium Glycinate provides 275 mg of magnesium in a serving of three capsules, which is under the 350 mg supplement limit on its own.⁴

Medicines: two separate questions

Each one touches medicines in its own way. NIH lists tetracycline and quinolone antibiotics and oral bisphosphonates among the medicines whose absorption magnesium can reduce. Turmeric has a different caution: NIH's breastfeeding database says it may increase bleeding in people taking warfarin or antiplatelet drugs, and the warfarin label asks for more frequent INR checks whenever any botanical product is started or stopped, without naming turmeric.^1,4,24,25

Ask your pharmacist how far apart to take them

The gabapentin label says an antacid containing magnesium and aluminum hydroxides lowered the amount of gabapentin the body absorbed by about 20%. In a small study, 1 g of magnesium oxide taken with gabapentin lowered its absorption by about a third.^26,27,28

On the medicine's label

Ask your pharmacist how far apart to take them

The levothyroxine label lists antacids, such as those made with aluminum and magnesium hydroxides, among products that may reduce levothyroxine absorption by lowering stomach acid. In a small 2025 study, magnesium aspartate taken at the same time lowered levothyroxine absorption by 12%, and magnesium citrate by 7%, a drop too small to rule out chance.^29,30,31

On the medicine's label

If you take a prescription medicine, ask your pharmacist about each of the two separately.

Liver, kidneys, stones and who should ask first

Liver injury has been reported with turmeric and curcumin products, mostly highly bioavailable formulations. NIH's LiverTox database counts several dozen cases of acute liver injury, along with a low rate of short-lived rises in liver enzymes.^2,3,32

Supplemental turmeric raised urinary oxalate in healthy adults, which the researchers said could raise the risk of kidney stones in people prone to them.⁸

Curcumin makes the gallbladder contract: in healthy volunteers, single doses of 20, 40 and 80 mg shrank it by about 34%, 51% and 72% within 2 hours.³³

The risk of magnesium toxicity rises when the kidneys work poorly or have failed, because they cannot remove the excess.¹

Ask first if you have kidney disease, because the kidneys clear excess magnesium.¹
Ask first if you have liver disease or have had liver problems with any supplement.^2,3
Ask first if you have had kidney stones or gallstones. Turmeric raised urinary oxalate and makes the gallbladder contract.^8,33
Ask first if you are pregnant or breastfeeding. NCCIH says turmeric supplements may be unsafe in pregnancy.²

Questions people ask

Can you take turmeric and magnesium at the same time?

No source we read says to keep them apart, and none tested them together. Magnesium is absorbed better in several small amounts, and curcumin levels vary widely between products.^7,19

Does magnesium change how curcumin is absorbed?

No study we found measured it. What is known to change curcumin levels is the form: in head-to-head studies, absorption-enhanced forms put about 1.3 to 46 times more curcuminoids into the blood than standard curcumin, and 20 mg of piperine raised bioavailability by 2,000%.^5,19,20

What if you get stomach upset after starting both?

Both can cause it, so you cannot tell which is responsible. High magnesium intakes from supplements can cause diarrhea, nausea and cramping, and turmeric taken by mouth can cause nausea, acid reflux, stomach upset, diarrhea or constipation. Starting one at a time makes the cause easier to spot.^2,4
