Abstract: The fitness industry has experienced rapid growth in recent years, leading to increased consumption of gym supplements such as protein powders, pre-workout formulas, and vitamins. This study aims to analyse consumer preferences towards gym supplements and understand the factors influencing their purchasing decisions. The research focuses on aspects such as brand perception, price, effectiveness, safety, and the impact of marketing strategies and social media. Primary data was collected from 100 respondents using survey methods and analysed using percentage analysis and the Chi-Square Test. The findings show that 31% of respondents use supplements mainly for muscle gain, and 43% prefer MuscleBlaze brand supplements. The analysis also reveals that monthly income has a significant association with gym workout frequency, while age group has no significant association. The study concludes that consumer preference towards gym supplements is influenced by fitness goals, affordability, marketing influence, and awareness about product quality and safety.
