What Should People Know Before Taking Supplements

Reda Elmardia Registered Dietician, Certified Nutritionist, Certified Strength and Conditioning Specialist Trainer and owner of thegymgoat.com explains, “Supplements are not regulated by the FDA. This means that they are not tested for safety before being sold to consumers. If something goes wrong, there is no way to know if it was caused by the supplement or the manufacturer. In addition, many manufacturers do not disclose what exactly is in their products. Many supplements contain ingredients that have been proven to cause harm. Some examples include caffeine, ephedra, and other stimulants. Others may contain harmful amounts of iron, zinc, magnesium, or vitamins A, D, E, K, and B12. Supplements can interact with medications. This is especially true for those who use prescription drugs. Taking certain supplements at the same time as your medication could lead to serious side effects. Supplements can interfere with your body’s natural processes. When taken without medical supervision, supplements can cause unwanted reactions in the body. They can affect how your body metabolizes food, hormones, and even medications.”

Elmardi explains, “Glucosamine sulfate is a natural product derived from shellfish. It is often included in dietary supplements marketed to help people with joint pain associated with osteoarthritis. But glucosamine isn’t helpful for everyone; some research suggests it might even cause problems like stomach ulcers and kidney stones.”

dr Seema Bonneythe founder and medical director of the Anti-Aging & Longevity Center of Philadelphia says, “Vitamin A high intakes of some forms of vitamin A can be harmful. Taking more than 10,000 IU vit A daily long term increases risk of osteoporosis. Getting too much preformed vitamin A (usually from supplements or certain medicines) can cause dizziness, nausea, headaches, coma, and even death. High intake of preformed vitamin A in pregnant women can also cause birth defects in their babies.”

Elmardi adds, “Vitamin A is a fat-soluble vitamin that is necessary for vision, reproduction, bone formation, immune function, and skin health. However, too much can cause toxicity, especially in children. In fact, 1/3 of the world’s population has some degree of vitamin A deficiency.”

“Creatine is a naturally occurring substance that occurs in meat and fish,” Elmardi shares. “It has been used by athletes for years due to its ability to increase muscle mass. However, creatine can be dangerous if taken in large doses. This supplement is not regulated by the FDA and contains ingredients that have not been proven safe. Some of these include L-carnitine, beta-alanine, and taurine. These substances may cause serious health problems.”
