Both of us are in perimenopause and both of us are sleeping worse for it. Between us there are five children, three sports schedules, weekend fixtures, a running argument about screen time and another one about food. When we are this tired, nutrition is a long way down the list of reasons.
The short answer
- Eight nutrients have a link to tiredness that is officially recognised in the European Union. We list them below, in the exact wording the law permits.
- Recognised does not mean it is your cause. Tiredness has many origins and most are not nutritional.
- Iron is the nutrient most associated with tiredness, and our product does not contain any. We explain why below.
- If tiredness has lasted weeks, the question belongs with a doctor rather than with a tub.
- Pocket Adults is a daily multinutrient. It is not a diagnosis, and it is not a night's sleep.
Which nutrients actually sit in this story
Tiredness is not one mechanism, so no single nutrient owns it. What the evidence does support is a set of nutrients that act as cofactors in the pathway turning food into usable energy: if one is genuinely short, the pathway runs less well.
Eight of them share the same role here, each of which contributes to the reduction of tiredness and fatigue. That wording is on the EU Register of nutrition and health claims:
| Nutrient | In our product |
|---|---|
| Vitamin C | Yes |
| Vitamin B2 (riboflavin) | Yes |
| Vitamin B3 (niacin) | Yes |
| Vitamin B5 (pantothenic acid) | Yes |
| Vitamin B6 | Yes |
| Folate | Yes |
| Vitamin B12 | Yes |
| Magnesium | Yes |
| Iron | No |
Several of the same nutrients also contribute to normal energy-yielding metabolism. That is a different authorised sentence. It is still not "more energy", and it is still not sleep. There is no authorised sleep claim on these nutrients. We already wrote that page: Does vitamin D help you sleep?.
The word doing all the work in that sentence is "contributes". It does not say it resolves anything, it does not say the nutrient is your cause, and it does not promise you will feel different. It says the nutrient takes part in the processes involved. That is a modest statement, and it is modest deliberately.
Why this is rarely the answer
Most tiredness does not come from food.
It comes from sleeping badly or not enough, from long stretches of stress, from doing too much, from recovering from something, from a routine that changed. None of those improves with a multinutrient, and that is worth saying before listing nutrients rather than after.
There is also a very common ordering mistake. "I'm tired, so I'll take a multinutrient" uses the supplement as if it were a diagnosis. If tiredness is new, persistent, or does not lift with rest, the right sequence is to speak to your GP first. A blood test answers the question. A tub does not.
In Portugal that call is the family doctor or SNS 24. In Spain, your médico de familia. The NHS is one UK door among others, not the EU rulebook.
Teenagers are a different clock. That page is here.
Iron, and why we do not have it
If you searched for vitamins for tiredness, you have almost certainly read about iron. It is the nutrient most associated with this subject, and reasonably so. A 2003 BMJ trial in women with unexplained fatigue and low iron stores is one of the papers people mean.
Our product contains no iron. None of the three formulas.
The reason is simple, and it says something about supplements generally. Iron is a nutrient where excess is not harmless, where individual need varies enormously, and where the decision to supplement should follow a blood test rather than an assumption. In a daily multinutrient meant for whole households, children included, we did not think that decision was ours to make on your behalf.
Which means that if your question is specifically about iron, our product is not the answer. The children's iron page is here. The teenage-girl page is here.
What to do, in order
- Sleep first. It is the most common cause and the least interesting one.
- If it has lasted more than two or three weeks, book an appointment. Particularly if it came on suddenly.
- Look at eating as a whole, not as a list of missing nutrients. Irregular meals make more difference than any capsule.
- Only then does it make sense to ask whether a supplement has any role, and that is a conversation for whoever knows your history.

Where My Daily Pocket fits
| Formula | Vitamin C | Magnesium | B12 | Iron |
|---|---|---|---|---|
| Pocket Kids (4–11) | 80 mg | 100 mg | 25 µg | None |
| Pocket Teens (12–17) | 100 mg | 150 mg | 100 µg | None |
| Pocket Adults (18+) | 150 mg | 200 mg | 100 µg | None |
None of these scoops is iron. None is a sleep product. Kids is not sized for adult tiredness. Pregnancy needs prenatal care, not this pouch.
If you eat varied, sleep reasonably, and are still tired, a multinutrient is unlikely to change that. We will write that sentence rather than sell you an expectation.
What a daily multinutrient does is more modest: it sits beside some of the variety that goes missing in irregular weeks. Whether that is worth it depends entirely on your circumstances, not on an article. We still have no omega-3. A scoop is not a meal, and it is not a diagnosis.
FAQ
Which vitamins are for tiredness?
In authorised EU wording, vitamin C, B2, B3, B5, B6, folate, B12 and magnesium each contribute to the reduction of tiredness and fatigue. Iron is the nutrient most associated with the search, and we do not sell it.
Will Pocket Adults make me less tired?
The authorised wording is "contributes to the reduction of tiredness and fatigue." It does not say you will feel different. Most tiredness is not nutritional.
Why is there no iron?
Excess is not harmless, need varies, and a household powder should not make that call. Blood test first.
How long until I feel something?
Most people feel nothing. That page is here.
Is this a sleep product?
No. There is no authorised sleep claim on these nutrients.
