Compare over 100 Vitamin Brands and Find the Right One for You




Compare the best multivitamins
Did you know that many vitamin supplements are not effective?
Do you know exactly what you’re getting when you buy vitamins at the store?
You want to improve your health, feel better, and boost your energy levels, and you wonder if the multivitamin supplements you see at the grocery store can help. Unfortunately, the honest answer is "no" in most cases – but as you’ll see, there are vitamins that will help you feel more energetic and healthier. You just need to know what they are and where to find them.
The vast majority of vitamins and other nutritional supplements that you find at the store are practically worthless, and buying them is a waste of your money. To find the few that are truly effective and give you good value for money, you need to tune out the marketing noise and do just a little independent research. You’ll soon discover the best multivitamins to take.
This Multivitamin Guide is a good first step in your research. We’ve done scientific comparison and multivitamin reviews of over 100 brands, including popular supplements such as Centrum, One-A-Day, GNC, Shaklee, Nutrilite/Amway, Equate, Nature Made, NOW Foods, Melaleuca, and Puritan’s Pride.
After six years of scientific research and reviews, we have the detailed information you need to decide which vitamin is best for you. Each vitamin was evaluated against four key parameters: composition, potency, bioavailability, and safety. Then each supplement was assigned a score from 0 to 10 so you can easily compare the different brands and determine the best multivitamin to take.

Findings of the comparison

Contrary to popular belief (and much advertising), some of the most widely available and well-known multivitamin brands received low scores, meaning they are not very effective. Some received such poor scores that they should be pulled off the market. To be honest, they’re not much more effective than a simple sugar pill.
Let’s look at where store brand vitamins went wrong in our reviews:
  • Their compositions do not follow the Optimal Daily Intake index, so from the start, they’re poorly formulated.
  • Their bioavailability is low, meaning the body does not absorb them well.
  • Finally, their potency levels are below the Optimal Daily Intake index, so you’re not getting the vitamin strength you need.
The reviews found that only eight multivitamin brands met or exceeded the benchmark of 8.0 for high supplement quality, potency, and bioavailability. You may not have heard of these brands, so we show you where to find them.
Use our guide to look for a vitamin with a score that exceeds 8.0, which is excellent. Unfortunately, the vast majority of vitamin products do not come close to that benchmark.
We strongly advise using a multivitamin product with a score of 8.0 or above for best results
