The supplement industry is built on hype. Most products do nothing meaningful. But there are a handful of supplements with strong evidence behind them that are worth your money.
Creatine monohydrate is the most researched performance supplement in existence. 3 to 5 grams per day improves strength, power output, and muscle hydration. Take it daily, timing does not matter. No loading phase needed.
Protein powder is not magic, but it is convenient. If you struggle to hit your protein target through whole foods, a quality whey or casein protein helps you close the gap. Think of it as food, not a supplement.
Vitamin D3 is essential if you do not get regular sun exposure. Most people are deficient. 2,000 to 5,000 IU daily with a fat source. Get your blood levels tested to dial in the dose.
Magnesium is involved in over 300 enzymatic reactions. Most people do not get enough from food. Magnesium glycinate or threonate before bed supports sleep quality, recovery, and muscle function.
Fish oil (omega-3s) supports cardiovascular health, reduces inflammation, and aids recovery. Look for products with high EPA and DHA content. 2 to 3 grams of combined EPA/DHA per day is a solid dose.
Everything else is situational. Caffeine is useful pre-workout. Electrolytes matter if you train hard or eat low carb. Beyond that, most supplements are not worth the money. Focus on training, nutrition, and sleep first. Those are your real performance enhancers.
