Magnesium Bisglycinate and Vitamin B6: Should You Combine Them?
STATE editorial team · Updated Oct 6, 2026
In this article
Should you combine magnesium bisglycinate with vitamin B6? The combination appears in many supplements, but B6 is not an essential addition for everyone. Bisglycinate describes a form of magnesium; B6 is a separate vitamin. Compare daily doses, your other products and tolerance rather than choosing only because both names appear on a jar.
A short formula can make sense. A formula with B6 can also be appropriate if it matches an identified need. These pointers help distinguish nutritional roles from promises of results.
What does magnesium bisglycinate mean?
Magnesium bisglycinate combines magnesium with glycine, an amino acid. The term describes the ingredient's chemical form, not the amount of magnesium actually provided by a capsule.
Look for “magnesium” or “elemental magnesium” per daily serving. The weight of bisglycinate and the weight of magnesium are not interchangeable. Compare equivalent servings rather than a prominent number on the front of the pack.
Also check the full ingredient list. A “buffered” formula can differ from one containing only a single magnesium source. Ask the manufacturer for clarification if the list does not make the sources clear. The form's name alone cannot guarantee greater effectiveness or freedom from digestive discomfort.
Why is vitamin B6 included with magnesium?
Vitamin B6 is involved in protein metabolism and normal nerve function. Magnesium also plays a role in nerve and muscle function. Their nutritional roles explain why they appear in shared formulas; they do not establish that everyone needs to supplement them together.
Fatigue or a stressful period does not automatically mean you lack both nutrients. These experiences can have many causes. Ask what your diet provides and what need you are trying to address.
Is magnesium with B6 more effective?
A 2018 trial in 264 stressed adults with low magnesium blood levels found no overall advantage for the combination over magnesium alone; a benefit appeared in a severely stressed subgroup. The study, whose authors disclosed links with Sanofi, had no placebo group and did not specifically test bisglycinate. It therefore cannot establish the value of every “bisglycinate + B6” formula.
Our practical interpretation: the combination can be discussed, but adding B6 is not automatically an improvement. Results in one population do not promise the same outcome for everyone.
Vitamin B6: check the dose and overlapping products
In 2023, EFSA set a tolerable upper intake level of 12 mg of vitamin B6 per day for adults, including food and supplements. This is a safety limit for habitual intake, not a target or recommended supplement dose. Excessive prolonged B6 intake can cause peripheral neuropathy.
List your multivitamins, B complexes and other supplements before adding a product. Check amounts per daily serving and add up the B6 supplied by supplements. Remember that food also provides this vitamin.
If tingling, burning sensations or numbness develop during supplementation, seek medical advice promptly and report every product you take. A vitamin is not risk-free simply because it is sold without a prescription.
How to compare two supplements
| Check | Question to ask |
|---|---|
| Elemental magnesium | How many milligrams does the daily serving provide? |
| Magnesium sources | Does the complete list identify the form and any other sources? |
| Vitamin B6 | How much does the serving contain, and are you taking it elsewhere? |
| Directions | How many capsules, what precautions and what spacing from medication? |
| Tolerance and review | Does it suit you, and why are you taking or continuing it? |
This guide helps you read a label; it is not a prescription. If you have kidney disease or take medication, seek advice before taking magnesium. Some medicines require separation from mineral supplements.
With or without B6: Calm Core as an example
The current STATE Calm Core page lists 250 mg of elemental magnesium per two capsules, as buffered bisglycinate, with no B6 listed in its composition. Read the formula for what it provides, without assigning it properties of a combination it does not contain. Always check the label on the product received.
For timing, follow the product directions and choose a habit compatible with your medication. Our when to take magnesium guide explains morning, evening and meal considerations. For food, also explore magnesium-rich foods.
Frequently asked questions
Is B6 essential with magnesium bisglycinate?
No. Consider its inclusion in light of the formula, dose and individual circumstances. Bisglycinate does not imply that a formula is missing something if B6 is absent.
Does B6 guarantee better magnesium absorption?
This is not a general guarantee for every formula or reader. Look for product-specific evidence rather than inferring performance from two ingredient names.
Magnesium glycinate or bisglycinate: what should you compare?
These terms are often used for a form linked to glycine. The complete ingredient list and elemental magnesium dose remain the useful comparison points.
Can you combine a B complex with magnesium containing B6?
Do not combine products without checking amounts. Total B6 can become high even when each product appears reasonable on its own.
How long should you take the combination?
There is no universal duration for everyone. Follow the label and seek advice on whether to start or continue supplementation, particularly if symptoms persist.
