Can you get too many vitamins?

Daily Value and Recommended Dietary Allowance (RDA)

Recommended Dietary Allowance (RDA) is the amount of a nutrient that the U.S. Food and Drug Administration recommends for the typical person based on age and gender.

The Daily Value (DV%) that you see on dietary supplement labels is the percentage of the RDA that one serving of the product provides. For example, if the DV% for Vitamin C is 100%, it means that one serving provides the full recommended daily amount of Vitamin C.

If the DV% is 500%, it means that one serving provides five times the recommended amount.

How Much is Too Much?

Some people think it’s okay to take way more than the recommended amounts of vitamins. They say that what you don’t need won’t hurt you. But that’s not true for all vitamins, or all people. Excess amounts of certain nutrients can cause vitamin toxicity and create serious health issues.

Unused amounts of fat-soluble vitamins like Vitamins A, D, E, and K do not get “flushed out” as waste. They get stored in your body and can build up to harmful levels over time. Even water-soluble vitamins, if taken in excessive amounts, can cause problems. For example, some studies have shown an increased risk of kidney stones from taking too much Vitamin C supplement. Others suggest that too much folate (Vitamin B9) can increase the risk of prostate cancer.*

If you prefer to take the recommended amounts of vitamins, you could try splitting a typical multivitamin in half. But you can’t split capsules, and broken tablets can have sharp edges that are hard to swallow.

Also, even half a tablet can be much more than you want. For example, if your current multi provides 18,000% of Vitamin B12 (as some brands do), you’ll still be getting 80 times the recommended amount!


That’s why we created Dr. Siegal’s® Just Enough™ premium multivitamins.

Unlike brands that provide hundreds or thousands of times the recommended amounts, one Dr. Siegal’s® Just Enough™ multivitamin a day provides no more than 100% of the Recommended Dietary Allowance of 27 nutrients, including vitamins, minerals, amino acids, and Coenzyme Q10 (CoQ10).

Just Enough means just the recommended amount.

In a perfect world, everyone would get all the nutrition they need from food.

Of course, hectic schedules and the irresistible convenience of packaged foods and drive-thru windows ensure that few people do.

One Dr. Siegal’s® Just Enough™ daily multivitamin provides a nutritional foundation based on the Recommended Dietary Allowance.*

Your “milder potency” multivitamin. Just the recommended amount.

What if I Need More of Certain Nutrients?

If you need greater amounts of particular vitamins or minerals due to medical conditions or lifestyle factors, you can supplement the nutrients you get from your multivitamin and food with one or more single nutrient supplements.

This is a targeted and sensible way to get increased amounts of specific nutrients without piling on excess amount of others.
