Tips to Choose the Best Quality Multivitamin

1. Go for Activated Nutrients

Vitamins and nutrients can either be inactive or inactive forms. It’s better to go for active forms as our bodies absorb them better. 

For instance, in the case of vitamin B6, choose pyridoxine 5-phosphate (active) instead of pyridoxine (inactive). Likewise, go for riboflavin-5-phosphate instead of inactive riboflavin. 

2. Look for Third-Party Testing

Multivitamins don’t have to meet any regulations. So, always look for third-party approval from recognized agencies or websites like ConsumerLab, USP (United States Pharmacopeia), or Labdoor.

3. Vitamins Shouldn’t Cross 100% DV

Don’t buy multivitamins that provide over 100% DV for vitamins or minerals. Our bodies can only absorb a limited amount of nutrients and excretes any extra vitamins or minerals.  

Men and postmenopausal women should aim for 50% DV for iron.

4. Limit Intake of Vitamin A

Don’t buy multivitamins that contain over 3,000-3,500 International Units (IUs) of vitamin A or retinol. 

5. Go for Folate Instead of Folic Acid

Some people cannot convert folic acid easily into its active form. So, it’s always better to take folic acid that exists naturally in leafy vegetables. Also, the activated form is better than the inactive form, as we discussed above.

6. Look for Vitamin E Complex

Check the label of your multivitamin. See if it says the vitamin E is available as mixed tocopherols, which means you have all the vitamin Es. 

7. Check for Additives and Fillers

It’s better to choose multivitamins free of gluten, artificial colours, flavours, or sweeteners. 

8. Test the Claims

Companies make all sorts of claims on their multivitamins. On closer inspection, you find the claims don’t have any evidence to back up. So, always be cautious and adopt precautions. Look for certifications such as GMP that gives at least a certain credibility to the product. 

9. Avoid Revolutionary Formulas

It’s best to go for basic multivitamins without any added benefits like weight loss or a healthy heart. The reason is that many times the claims are baseless. Also, the products cost much higher than basic multivitamins. 

10. Buy Generic for Affordability

Generic multivitamins are often cheaper than branded ones and provide the same quality. But always research the product before buying. 

We are almost done with our choose the best quality multivitamin guide. Before we conclude, let’s check out a few important terms related to multivitamins.
