Ask a Dietitian: Do Vegetarians Need to Take a Multivitamin?

The Question

I'm vegetarian — do I have to take a multivitamin every day?

The Dietitian's Answer

It's not a must, but for many people it's a practical form of insurance. If your diet is already varied and rich, and key nutrients like B12 and vitamin D are already covered through fortified foods or standalone supplements, skipping a multivitamin is perfectly fine. A multivitamin tends to be more useful in these situations:

• Your diet isn't very varied and you often eat the same handful of foods on repeat
• You're trying to conceive, pregnant, or breastfeeding — stages when nutrient needs rise
• You're older or have reduced digestive absorption
• You've been dieting long-term or eating irregularly

What to Look for in a Multivitamin

Favor products that clearly list B12 and vitamin D content, with doses close to the recommended intake — there's no need to chase higher and higher amounts. If you're also taking separate B12 or iron supplements, check whether the multivitamin duplicates these ingredients, to avoid stacking up an excess — this deserves particular attention for fat-soluble vitamins (A, D, E, K), where the risk of overdoing it is relatively higher.

A Reminder

A multivitamin supplements the diet — it can't replace improving your overall eating pattern. If the underlying diet stays unbalanced long-term, a multivitamin alone will do only so much to make up for it.
