Awareness and Use of Dietary Supplements Among Fitness Enthusiasts in Abuja Gyms, FCT

The use of dietary and sports supplements has grown substantially among gym-attending populations in Nigerian urban centres, often without professional guidance or adequate knowledge of safety and efficacy. This study investigates the awareness, patterns of use, and motivations for dietary supplement consumption among adult fitness enthusiasts attending commercial gymnasiums in Abuja, FCT. The increasing prevalence of supplement use in the absence of evidence-based nutrition counselling raises concerns about overuse, adverse effects, and financial exploitation. A descriptive cross-sectional design was employed, with 240 gym members aged 18 to 45 years recruited from six registered gymnasiums in Garki, Wuse, and Maitama districts. A structured questionnaire assessed types of supplements used, frequency and dosage, knowledge of active ingredients and safety profiles, sources of information, and motivating factors. Anthropometric measurements and dietary intake assessments were included. Findings are anticipated to show widespread use of protein powders, creatine, and herbal supplements, with most users obtaining guidance from gym instructors rather than qualified nutritionists or dietitians. Misperceptions about supplement necessity and effects were common. This study recommends stronger regulatory oversight and the integration of certified nutrition advice within commercial fitness settings in the FCT.
