Do I really need all these supplements?

No. Start with the foundation: protein, creatine, vitamin D, omega-3. Add others based on your training intensity and diet gaps. A beginner stack costs under $100/month at TNF.

Can I take everything at the same time?

Most yes, but a few interact: iron + zinc compete with each other, magnesium + calcium compete, and caffeine + iron reduces iron absorption. Spread these across different meals.

How long until I see results?

Creatine: 2-4 weeks for strength gains. Whey protein: immediate (paired with training). Vitamin D: 4-8 weeks to fix deficiency. Ashwagandha: 4-8 weeks for stress + sleep benefits.

Are these supplements safe and legal in Canada?

Every product we sell complies with Health Canada Natural Health Products regulations and CFIA food labeling. We are a licensed Canadian retailer based in Montreal, Quebec.
