Supplements are one of the most confusing parts of the fitness industry.
One person swears by a supplement.
Another says it’s useless.
Brands promise miracles.
Influencers sell stacks you don’t need.
The truth is simple: Supplements don’t replace nutrition, training, or lifestyle. They support them.
When used correctly, supplements can:
Fix real nutrient gaps
Improve recovery and performance
Support fat loss and muscle gain
Prevent long-term deficiencies (especially common in modern diets)
When used blindly, they:
Waste money
Create false expectations
Sometimes do more harm than good
