What is a food supplement?

In Europe these are foods with a scoop, not a set you have to complete. Why two bottles often do the same job, and why we would rather you bought less.

160%: two products at 80% NRV of the same vitamin, if you take both

The cupboard already has a tub. The internet would like you to add fish oil, magnesium, and something for "women over 40". We have stood in that aisle.

The honest question is whether those are different jobs, or the same job sold three times.

The short answer

  • In Europe a food supplement is a food, sold as a scoop, a capsule or a measured drop, meant to sit beside dinner. It is not a medicine.
  • Amounts on two packs add. Two products at 80% NRV of the same vitamin are 160% if you take both.
  • Omega-3, iron and a broad multinutrient are different jobs. Two broad multinutrients are usually the same job twice.
  • We do not sell omega-3 or iron. If those are what you came for, look elsewhere rather than stacking us on top.
  • One product that matches the age on the pack is the usual honest basket.

These are foods, with a scoop

Europe has a rule for this. We looked it up because the aisle makes it sound more complicated than it is. A food supplement is food, in a dose you can count, whose job is to add something to what you already eat. That is Directive 2002/46/EC.

That gives you three things, and they are more useful than the marketing.

They are foods. They can carry the health claims Europe has actually signed off, in those exact words, on the EU Register. They cannot be sold as a medicine.

They sit beside dinner. The job is in the name: they supplement. A pack that talks as if dinner were optional is arguing with itself.

The dose is the product. A powder you scoop, a capsule you swallow, a liquid you measure. The daily amount on the label is the number that matters.

In Ireland the FSAI oversees this. In Portugal, the DGAV. In Spain, AESAN. Same Directive, three national doors. How to read the back of the pack is here.

Why two bottles can be too much of the same thing

The percentage on a pack is for that pack's daily dose. It has no idea about the other bottle in the cupboard. Regulation (EU) No 1169/2011 sets the adult NRVs so two packs can be compared. It does not add them for you.

If a multinutrient already gives you 100% NRV of B12, a second "energy" capsule with more B12 is not a second benefit. It is more B12. Some nutrients have a ceiling EFSA is willing to call tolerable. Others are simply wasted. Either way, you cannot see the total unless you add the labels yourself. That arithmetic is here.

Magnesium is the frequent double. It turns up in multinutrients at a modest amount, and again as a standalone evening product. That can be on purpose: our own magnesium is a complement, and we have already said a product that is only magnesium makes more sense if you want a full dose. It can also be an accident. Two modest amounts become one large one, and nobody is holding the sum.

Omega-3, iron, and a second multinutrient

People search for a multinutrient plus omega-3 plus magnesium as if that were a standard set.

Omega-3 is a fat from fish or algae. It is not in our formula. If you want it, that is a different shop, and putting a multinutrient on top does not create it.

Iron is a mineral with a narrow margin. We do not include it. A second product that does, taken because a multinutrient "felt incomplete", may be the right call and may be the wrong one. That is a GP conversation, not a bundle.

A second multinutrient is the one we would talk you out of. The nutrients overlap. The % NRV adds. You pay twice for the same B vitamins.

The honest basket, for most households, is one broad product that matches the age on the pack, plus a specific second product only if you can name the job it does. "It was on offer" is not a job.

Where My Daily Pocket fits

We sell one daily powder in three strengths. Of course we would like it to be the one in the cupboard.

Formula Age line What it is What it is not
Pocket Kids 4–11 One daily multinutrient powder Iron. Omega-3. Calcium. A second multinutrient.
Pocket Teens 12–17 The same idea, teen amounts The same four.
Pocket Adults 18+ The same idea, adult amounts The same four. A 40+ birthday formula. Pregnancy as prenatal care.

The truthful limit is also obvious. We are not a complete nutrition strategy. We have no omega-3, no iron, no calcium, no vitamin A, no vitamin E, no biotin. A person who needs those still needs those. Using us as a reason to skip them, or stacking us with two other multinutrients "to be sure", are both mistakes we would rather not be paid for.

If this page empties someone's cupboard a bit, that is the point of it. The after-40 version of the birthday label is here.

Empty the cupboard onto the table

  1. Put every bottle out. Add the daily amounts for each repeated nutrient.
  2. Drop any second multinutrient that duplicates the first.
  3. Keep a standalone only if you can say, in one sentence, which nutrient it is for.
  4. Read the age line. A children's formula and an adult formula on the same person is the same duplication with worse arithmetic.
  5. If you cannot name the job, you do not need the bottle.

FAQ

Is a food supplement a medicine?

No. In the EU it is a food, in a counted dose, meant to sit beside dinner. Directive 2002/46/EC.

Can I take two multinutrients?

You can. The amounts add. That is usually the same B vitamins twice. We would talk you out of it.

Do you sell omega-3 or iron?

No. If those are the jobs, look elsewhere.

What does % NRV mean when I stack?

It is per pack, against an adult ruler. Two packs at 80% are 160% if you take both. Add milligrams, not vibes.

Who watches this in Portugal or Spain?

DGAV in Portugal. AESAN in Spain. FSAI in Ireland. Same European rule.
