When a consumer buys a supplement or doctor recommends a supplement, there is a higher chance that the manufacturer has a relationship with the consumer. Most supplements are regulated and you should look for this. The following information is for consumers who want to purchase supplements. I am not a doctor and don't endorse or recommend products that I don't have clinical experience with. Most consumers buy supplements on the Internet. You can often find information on the Internet about what a supplement is, what it does, and what other people think it does. Some companies have a reputation for being the "best." But what are the true ingredients in their products? Many supplements have been shown to be ineffective. They may be effective for a short time or even cause adverse reactions. There is no way to know what is in the supplement you are taking until it is in your body. I would recommend taking a supplement only if you are sure that it is what you want. I suggest you get advice from a qualified doctor or a doctor who has been doing research on these products. If you think that a supplement will improve your health, look for a company that has an active ingredient, or at least a sponsor.
