Everyone who is trying to get healthy may be tempted to take supplements. Many offer to make you bigger, stronger, smaller, happy and healthier. But before you decide on which supplements are the best for you, do your research. The FDA has recalled hundreds of dietary supplements over the years that have been linked to serious side effects. But because many are not considered to be foods or drugs they still make it to the market. Below are some supplements considered to be among the worst and some that may be legal but still not considered the best for your body. Whatever you decide, it's recommended you talk to your doctor before adding anything to your diet.


 Craze Performance Fuel

This supplement says it will give you endless energy but it's believed this energy is provided by a secret ingredient, which is similar to meth. The effects of the compound in question aren't that clear but amphetamines are known to increase central nervous system activity, heart rate and blood pressure and could lead to cardiac arrest.



TadalafilSildenafil Image: shutterstock.com

Many supplements have been yanked because they contain tadalafil or sildenafil, which are the active ingredients in Cialis and Viagra. Those prescription drugs are used to treat erectile dysfunction by opening up blood vessels but they can also react with nitrates and cause blood vessels to become dilated, which could cause a fatal drop in blood pressure. Some of these banned products include True Man Sexual Energy, Friminite, Love Rider, Jack Rabbit, SexVoltz, Virilis Pro, Silver Sword, Lightning Rod and Rock-It Man.

Gamma Butyrlactone was marketed as a cure-all for several things, including sleep issues, aphrodisiac, antidepressant, weight-loss aid and hair thickener but some say it was just a way to feel high. The body converts GBL into gamma hydroxybutyrate – GHB – which is used sometimes as a date-rape drug. It was banned after the government found it could cause comas and death, as well as vomiting, difficulty breathing and loss of bowel control.


OxyElite Pro

This was known as a “fat burner” but has been linked to dozens of cases of hepatitis in Hawaii. Some believe the issue is with aegeline, a synthetic version of a compound found in the bael tree.

Chinese Herbal Supplements

The FDA recalled a range of Chinese herbal supplements produced by Herbal Science International Inc. after they were found to contain ephedrine, aristolochic acid and human placenta. A debate arose over whether or not eating human placenta constituted cannibalism. As well, scientists believe that eating it can transmit blood-borne diseases like hepatitis or HIV.

This supplement comes in both pill and powder form and is used after workouts to help build muscles. But some believe it can also result in kidney damage, significant dehydration and could also worsen asthma. Consult a doctor before you consider taking this supplement.

Many women over 50 have been told to take this supplement but some believe the mineral has a difficult time being absorbed in older bodies, which could lead to it being absorbed in artery walls instead of bones. This could lead to the hardening of the arteries, heart disease and stroke. If you need to take calcium supplements you should talk to your doctor to find the best ones for your body.


Soy Isolate

This supplement comes in capsules, protein bars and shakes but people over 50 should watch just how much soy isolate they take. It can have an estrogen effect in men since, as they age, men's bodies need to balance between testosterone and estrogen. If they're taking something with an estrogen effect it can cause breast formation.


Carb Blockers

Carb blockers sell because they make people think carbohydrates make them fat. But carbs are needed in the body. Carb blockers can lead to many side effects including bloating, gas, nausea, vomiting and diarrhea.
