Why Most Multivitamins Are a Waste of Money

Here’s the short version: most multivitamins on the market don’t do much. The blunt reason is economics — a company sources cheap raw ingredients (say, 10 lira worth), spends far more than that on marketing (100 lira), and sells the result at a steep markup (200 lira). If a genuinely obscure, no-name company told you “we use the best ingredients available,” would you actually trust that claim without the marketing budget behind it? Probably not — which is exactly why marketing ends up mattering more than formulation for most brands.

That’s the general rant. Here’s the actual practical part — worth taking notes on:

• If a multivitamin lists magnesium oxide as its magnesium source, skip it. It’s the cheapest, least bioavailable form of magnesium — if a company chose this over the pricier, genuinely effective forms, that’s a strong signal the rest of the formula is cutting corners too. Between this and the point above, you can probably rule out something like 99% of multivitamins on the shelf.
• If it lists calcium carbonate, also a red flag for the same reason — it’s not harmful, but it’s a cheap filler included mainly so the label can say “contains calcium.”
• Watch for products that pad out a weak core formula with caffeine, taurine, and similar stimulants — designed purely so you feel something after taking it and assume that means it’s working.
