Can you take NMN with other supplements? An NMN stacking guide

You can take NMN alongside most everyday supplements. The ones people add most are creatine, CoQ10, vitamin D3 and K2, magnesium and resveratrol. What to check when you stack NMN is overlap: the same ingredient in two products, or a daily total that goes past the NHS's safe amount.

What people take with NMN, and how to take each one

Supplement	Daily amount in ours	With food?	Check this
Creatine monohydrate	3 to 5g	Not needed	Tell your GP you take it before a blood test.
CoQ10	100 to 300mg	Yes, with a meal	Speak to your doctor first if you take blood thinners or blood pressure medicine.
Vitamin D3 and K2	75µg D3, 100µg K2	Yes, with some fat	Count every source of vitamin D. Vitamin K affects warfarin.
Magnesium	1 to 3 capsules	Yes	Count magnesium in any multivitamin as well.
Resveratrol	150mg	With a meal is common	NMN Complex already contains 120mg.
TMG	600mg, inside NMN Complex	Either	Do not add a separate TMG if you take NMN Complex.
Marine collagen	10g	Either	Made from fish. Not for anyone with a fish allergy.

NMN itself can go in at any point in the day, with or without food. If you take levothyroxine, keep that on its own first thing; our guide to NMN and medication explains why.

Can you take NMN and magnesium together?

Yes, you can take NMN and magnesium together. I have not found any study or NHS warning about combining them, and you do not need to space them apart. Take magnesium with a meal, as the label on ours says, and NMN whenever suits you.

The thing to check is your total magnesium. The NHS says 400mg or less a day from supplements is unlikely to cause harm, so add up what is in any multivitamin as well. Our Magnesium Complex gives 375mg in 3 capsules, which is 100% of the reference intake.

Check for the same ingredient in two products

This is the mistake I see most when people send me their routine. Someone buys NMN Complex, then adds a resveratrol pot and a TMG pot because a stacking list told them to, and ends up taking two or three of the same thing.

NMN Complex already contains, in three capsules:

• 500mg NMN
• 600mg TMG
• 120mg trans-resveratrol
• 120mg pterostilbene
• 300mg quercetin
• 150µg vitamin B12

If that is your NMN, you do not need separate TMG or resveratrol. If you would rather choose each ingredient and dose yourself, Pure NMN is one ingredient, and you build around it.

Stay under the NHS daily limits when you add everything up

Stacking problems are rarely about one product. They come from totals across several. These are the NHS's figures for the nutrients most likely to double up in a supplement routine:

Nutrient	NHS figure	In our products
Vitamin D	Do not take more than 100µg (4,000 IU) a day	75µg (3,000 IU) in one D3 and K2 capsule
Magnesium	400mg or less a day from supplements is unlikely to cause harm	100% of the reference intake in 3 magnesium complex capsules
Vitamin B12	2mg or less a day from supplements is unlikely to cause harm	0.15mg in a daily serving of NMN Complex

Here is how the vitamin D one catches people out. Our D3 and K2 capsule gives 75µg. Add a multivitamin with 25µg, which is common, and you are at the NHS maximum of 100µg before you count anything else. If you take a multivitamin, read its label before adding a separate vitamin D.

How to fit a stack into one day

Most routines fit into two moments. Anything that says take with food, such as CoQ10, vitamin D3 and K2, magnesium and resveratrol, goes with your biggest meal, ideally one with some fat in it. NMN and creatine can go in whenever suits you, so I put them first thing because that is when I remember.

Splitting supplements across five slots in a day looks precise on paper, but in my experience it mainly makes people miss doses. Two slots are easier to keep up for months.

Add one supplement at a time

If you are new to all of this, start NMN on its own for a couple of weeks, then add the next product. If your stomach disagrees with something, or a blood test comes back different, you will know which product to look at. Starting five at once makes that impossible.

What I would not add to an NMN stack

St John's wort, if you take any prescription medicine. It is the one supplement the NHS names as not mixing well with warfarin, apixaban, sertraline, atorvastatin and amlodipine, the medicines I checked for our medication guide.

I would also not take NR and NMN together. They are sold for the same reason, so taking both mostly doubles what you spend. Pick one.

And I would skip any stack built from a famous person's routine. Those lists change, they are rarely dosed the way the person actually takes them, and they are written for someone else's health and budget. If you want a sense of how creatine fits alongside NMN specifically, our creatine and NMN guide covers doses and timing.
