Why magnesium and B6 are sold together
Magnesium with B6 is one of the most common pairings on supplement shelves. The EU has authorised separate health claims for each nutrient, and several of them cover the same ground: tiredness and fatigue, the nervous system and psychological function. One product with both means one jar to remember instead of two. The EU has not authorised a claim for the combination as such, so every claim on this page belongs to one nutrient.

How much magnesium and B6 to look for
Read the line for elemental magnesium, not the weight of the compound. A product may carry a magnesium claim only if its daily dose gives at least 15% of the NRV, which is 56.25 mg. Every product above clears that bar, from the OstroVit magnesium and potassium tablet at exactly 15% to four 7Nutrition capsules at 112%.
B6 varies far more. 1.4 mg is 100% of the NRV, and most products here contain several times that. In 2023 EFSA set the tolerable upper intake level for vitamin B6 at 12 mg a day for adults, counting all sources together. Four 7Nutrition capsules reach that level on their own. If you also take a B-complex or a multivitamin, add up the B6 from every product, and stay within the daily dose on each label.
Pyridoxine or P-5-P
Labels list vitamin B6 in one of two forms. Pyridoxine hydrochloride is the standard form in most supplements. Pyridoxal 5'-phosphate (P-5-P) is the form the body uses in its enzymes, and OstroVit uses it in Triple Magnesium and in the malate powder. Both count toward the same NRV, and the authorised claims apply to vitamin B6 in either form.
Which magnesium form to choose
Citrate, diglycinate (also sold as bisglycinate or glycinate) and malate are organic magnesium compounds that dissolve well in liquid. Triple Magnesium mixes carbonate, citrate and lactate. If you want a powder to stir into water, the malate is the only powder in this category. If you want fewer units a day, Labs212 needs two capsules, and Triple Magnesium gives 375 mg in three. Each form is explained in more detail on the main magnesium page.
EU health claims
Regulation (EU) No 432/2012 allows these statements for products whose daily dose gives at least 15% of the NRV of the nutrient:
- Magnesium contributes to a reduction of tiredness and fatigue.
- Magnesium contributes to normal functioning of the nervous system.
- Magnesium contributes to normal muscle function.
- Magnesium contributes to electrolyte balance.
- Magnesium contributes to normal psychological function.
- Vitamin B6 contributes to the reduction of tiredness and fatigue.
- Vitamin B6 contributes to normal psychological function.
- Vitamin B6 contributes to normal functioning of the nervous system.
- Vitamin B6 contributes to the regulation of hormonal activity.
- Vitamin B6 contributes to normal energy-yielding metabolism.
Questions
Is magnesium B6 better than magnesium alone?
No authorised claim says so. The point of the pairing is convenience: two nutrients in one product. If you already get B6 from another supplement, a magnesium product without B6 keeps you from doubling it.
When should I take magnesium with B6?
Follow the label. Labs212 says to take the capsules after a meal with water, and 7Nutrition gives a range of 2 to 4 capsules a day. Taking the dose at the same time every day makes it easier to remember.
Is the magnesium and potassium tablet in this category too?
Yes. The OstroVit tablet contains all three nutrients in small amounts: 56.25 mg of magnesium and 0.21 mg of B6, each 15% of the NRV. You will also find it under magnesium with potassium.
