Also, some supplements might have active ingredients known to increase the risk of bleeding which might not be good for people who are going for surgery. The other reason that could cause severe side effects is when patients decide to stop their medication to replace them with natural diet supplements. 

This is dangerous and could be fatal. That’s why any person with a pre-existing condition need to consult with their doctor or physician before taking any supplement. This is to ensure that whatever you want to take does not interact with your essential treatment. As such these are some examples to look out for; 

 

  • Patients on Coumadin® to prevent blood from clotting should avoid taking Vitamin K because it can reduce the ability of the blood thinner.
  • Taking St. John’s wort might interfere and make ineffective the birth control and antidepressants pills.
  • Taking vitamin supplements like vitamins C and E interferes with some types of cancer chemotherapy thus making them ineffective. 

So, this means the safety of a supplement is also determined by individual medication and the treatment they are currently taking. It is important to put your health and treatments first. Even more, certain food especially cereals and beverages are fortified with certain vitamins and minerals and as such supplement users should ensure they check how much of vitamins and minerals they are taking for the RDA and avoid overdose as it could be harmful to their health. 

The Labelling of Dietary Supplement 

It is imperative to look at the labelling of every dietary supplement before purchasing it to understand what is in the product you want to consume as a safety precaution.

Pregnant women only have iron and folic acid recommendation to prevent maternal anemia, peurperal sepsis, low birthweight and preterm birth.

Unless, the doctor prescribes any supplement of any kind, pregnant and lactating mothers should refrain for using dietary supplements. Also, little children should only be given the vitamins recommended for children any other supplements found over the counter are not safe for their immature and immune systems which could compromise their health. 

Federal Regulation of Dietary Supplements

Due to the fact that dietary supplements are not intended to treat, diagnose, alleviate, prevent, or treat diseases the FDA does not really have conduct a product pre-review for approval unlike the therapeutic drugs.  However, the FDA still oversee dietary supplements and watch out for harmful ingredients where they can ban dietary supplements that are harmful to consumers.

More importantly, the FDA require that manufacturers of dietary supplements provide some evidence on the safety of their product. Manufacturers are also required to make labels for their products as truthful as possible. The dietary supplements could carry messages like “this product addresses a nutrient deficiency, enhance and boost your immune system, it is a fat burner and metabolism booster, etc. 

However, such messages must be followed by “This statement has not been evaluated by the Food and Drug Administration. This product is not intended to diagnose, treat, cure, or prevent any disease.” This is to ensure that users do not stop taking their medication and replace them with these dietary supplements. 

The FDA is responsible for monitoring every dietary supplement on the market to ensure it is safe. Consumers using any dietary supplements are urged to report any side effects they had after consuming a dietary supplement to both the FDA and the manufacturer. 

And if the FDA finds a product to be unfit and unsafe, they could advise the manufacturer to voluntarily recall their product or the FDA could take action and remove the product from the market place so as to protect the public.
