FAQ

Do I really need supplements if I eat a healthy diet?

Supplements aren’t meant to replace real food — they complement your diet. Even with balanced eating, most people fall short on certain nutrients like Vitamin D, Omega-3s, or Magnesium. Supplements help fill those gaps, support performance, recovery, and overall wellness. The key is to use them strategically, not excessively.

When is the best time to take protein powder or pre-workout?

Protein powder: Best taken within 30–60 minutes after a workout to support muscle recovery and growth. It can also be used as a meal replacement or snack during the day.


Pre-workout: Take it 20–30 minutes before training for maximum energy, focus, and endurance during your session.

Are supplements safe to take every day?

Most high-quality supplements are safe when taken as directed. Always follow label dosages and consult your healthcare provider if you’re pregnant, nursing, or on medication. Choose trusted brands that are third-party tested and transparent about their ingredients — this ensures purity, potency, and safety.
