Magnesium, as a label note
Why this note
The authorised lines cover tiredness and fatigue, muscle function, and electrolyte balance, when the product is a source of magnesium.
In favour
- The wording is narrow and fixed.
- Source-of is a label check.
Against
- “Tiredness and fatigue” is not a claim about training recovery.
- It is not medical advice.
Authorised claims cover a reduction of tiredness and fatigue, normal muscle function, and electrolyte balance, when the product is at least a source of magnesium. “Tiredness and fatigue” is the authorised phrase. It is not a promise about session recovery, sleep, or cramp.
How to read this note
Start with the job of the product. Then read the trade-offs. The shop buttons come last, and they are advertising. Nothing above them is a test result.
What to look for
- Magnesium per serving, and the compound named on the label
- Whether the amount meets the source-of rule
- Other minerals bundled in, so you are not doubling up without noticing
- A format you will take consistently
What these supplement notes compare
The comparison is the wording on the label, not a promise about your training. Only authorised EU claims are quoted, and only with their conditions.
The authorised sentence
If a claim is not in the Union Register, it is not used here. No fat-loss lines, no recovery miracles.
The conditions
A daily amount, a source-of threshold, or a drink composition. The sentence applies only when the product meets them.
The person
Several claims are for adults. This site does not read symptoms and does not set a dose.
Authorised EU wording
“Magnesium contributes to a reduction of tiredness and fatigue.”
“Magnesium contributes to normal muscle function.”
“Magnesium contributes to electrolyte balance.”
Wording follows Regulation (EU) No 432/2012 and the Union Register of nutrition and health claims.
Supplement questions
Is this medical advice?
No. Food supplements are not a substitute for a varied diet and a healthy lifestyle, and they are not a substitute for medical advice. Pain and illness belong with a clinician who can assess you.
Why do you not name a dose?
A dose is a decision for you and, where it matters, for a clinician. The page only repeats the condition the EU attaches to the claim, such as 3 g of creatine a day for that one sentence.
