As cooler weather returns to the United Arab Emirates, a surge in outdoor fitness activities has coincided with a spike in the purchase of nutritional supplements. Residents are increasingly adding protein powders, multivitamins, magnesium, and electrolytes to their daily regimens to boost stamina and aid recovery. However, healthcare providers at major hospitals are issuing strong warnings against this trend, stating that an active lifestyle does not automatically necessitate additional nutrient intake. According to Khaleej Times, doctors emphasize that without confirmed deficiencies, adding these products can cause more harm than good.
Medical professionals report a growing number of patients arriving at consultations with complex supplement stacks. Dr. Mohamed Elgezouli, a family medicine specialist at Sheikh Sultan Bin Zayed Hospital in Sharjah, noted that many individuals rely on advice from gym trainers, friends, or social media rather than clinical data. He stated that most people consuming a balanced diet do not require these extra products, with the exception of vitamin D, which remains a common concern in the region. Even then, he stressed that supplementation should be confirmed through testing rather than assumed.
The risks of unsupervised supplementation are significant. Dr. Elgezouli warned that excessive vitamin D can raise calcium levels and damage the kidneys, while unnecessary iron intake can build up in organs. Swapna Mary John, a clinical dietitian at International Modern Hospital in Dubai, added that high doses of vitamin B6 can cause nerve damage. She also highlighted that combining multiple supplements can lead to unintended overdoses or dangerous interactions with prescribed medications, such as blood thinners and thyroid tablets. Dr. Marian Malak Eshak Morkos of Burjeel Day Surgery Center further cautioned that products marketed as natural are not inherently safe and can cause digestive issues or organ damage if taken in excess.
Experts recommend that residents undergo a comprehensive medical assessment before introducing any new supplements. This process should include blood tests for iron stores, vitamin D, vitamin B12, kidney function, and cholesterol. Dr. Elgezouli advised that individuals over 40 or those with heart risk factors should also complete a cardiac assessment before starting intense exercise. The goal is to identify specific nutritional gaps rather than following generic fitness trends. A personalized approach based on dietary habits, age, and medical history is considered safer and more effective than trial-and-error supplementation.
