Does magnesium glycinate contain zinc or vitamin B6?
No. Magnesium glycinate is a single ingredient, magnesium bound to glycine, with no zinc and no vitamin B6. The trio you are thinking of is ZMA, a different product. Add 10 to 15mg zinc separately if your diet runs short.

The direct answer, and where the question comes from
A plain magnesium glycinate contains magnesium, glycine holding it, a capsule shell and trace processing agents, and that is the complete inventory: no zinc, no vitamin B6, no third mineral riding along. The question exists because of ZMA, the trademarked lifter's blend of zinc, magnesium aspartate and B6 that shares shelf space, bedtime positioning and forum threads with glycinate, until the two blur into one vague night mineral in memory. They are different products with different ingredient counts, and the difference is not a gap in the glycinate; it is the design.
Why the single ingredient is the feature, not the omission
Three reasons the empty inventory is worth paying for. Dosing clarity: each nutrient has its own UK ceiling, 400mg for supplemental magnesium and 25mg for zinc, and separate bottles let each sit where it should, while ZMA's fixed 30mg of zinc lands over its guidance level every night by design. Pharmacy simplicity: the medication conversation this site keeps recommending is one mineral long for a glycinate, and a blend multiplies the questions. And test readability: whether you are running the sleep eight-weeker or the twitching month, a single-ingredient product means the result has one explanation, where a blend's result belongs to nobody. Blends sell convenience; singles sell knowing what happened.
| Plain magnesium glycinate (worked example) | ZMA | |
|---|---|---|
| Magnesium | 300mg elemental as bisglycinate, 80% NRV | 450mg as aspartate; oxide in some UK copies |
| Zinc | None | 30mg, above the 25mg UK guidance level |
| Vitamin B6 | None | 10.5mg, at the 10mg guidance level |
| Serving ritual | 2 capsules with any meal | 3 capsules, empty stomach, bedtime |
| Independent trial record | The magnesium literature, form-agnostic | Null on strength, body composition and hormones |
| Cost per day | 22p | 30p to 50p |
When zinc or B6 genuinely earn a separate place
Zinc earns one on dietary grounds only: a plate consistently light on meat, dairy, eggs and seafood can run short, and a separate 10mg to 15mg with food, under the 25mg guidance level, covers it while carrying zinc's own authorised claims, testosterone maintenance among them. B6 almost never earns one, because UK diets rarely lack it, its guidance level is a low 10mg on long-term use, and the vivid-dream folklore around it is recall, not benefit. Neither belongs welded to your magnesium at someone else's ratio. The clean architecture: Futuro Labs Magnesium Glycinate, 2 capsules with the evening meal, 300mg elemental at 80% NRV from bisglycinate at 20%, vegan, UK made under GMP and BRC, panels shown, £19.99 for 180 at 22p a day, plus a cheap standalone zinc on the days the plate justified it. Does magnesium glycinate contain zinc or vitamin B6: no, and after a page of reasons, hopefully good.

Questions people also ask
Is there zinc in magnesium glycinate?
Not in a plain one: the ingredient list is magnesium bisglycinate, a capsule shell and processing traces. Zinc appears only in blends that add it.
Should I take B6 with magnesium glycinate?
Only if a professional has identified a reason; UK diets rarely lack B6 and its long-term guidance level is a low 10mg. The glycinate needs no helper.
What has magnesium, zinc and B6 together?
ZMA, the lifter's blend. Its independent trial found no benefit and its zinc dose exceeds the UK nightly guidance level.
Do zinc and magnesium need to be taken apart?
At 300mg magnesium and 10mg to 15mg zinc they share a dinner without meaningful interaction; separation is optional caution.
Why buy single-ingredient supplements at all?
Ceilings stay respected, pharmacist conversations stay short, and any month-long test you run has exactly one explanation.
