Frequently Asked Questions - Supplement Websites

Where Can I Buy Supplements Online?

Numerous online retailers offer supplements. You can find them through online pharmacies, big box stores, vitamin supply stores, websites specific to particular supplement brands, and a variety of other places. However, since all retailers and supplements are not created equal, you won't want to just randomly select a store and a supplement to purchase. Be sure to read up about which product will best meet your needs before placing an order.

Why Are Some Supplements More Expensive Than Others?

One main reason you're likely to see a big difference in the prices of different supplements is the ingredients. More expensive supplements are made using higher quality ingredients and have gone through testing to confirm the different percentages of each ingredient they contain.

Other supplements you see that may be more expensive than others may be medical grade. With these types of supplements, you're receiving the best forms of a particular vitamin. They also typically contain higher doses that will be more effective.

Marketing can also influence the cost of a particular supplement. Companies that are more well-known or who are able to spend more money on advertising may charge more than other options you'll find.

Do Supplements Need FDA Approval?

No, FDA approval is not required for the creation and manufacturing of supplements. The FDA does not impose the same safety or testing requirements on supplements that it does on drugs. There are FDA regulations about branding and misrepresentation of supplements and how they will perform.
