Supplement routine FAQ

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.

Version française — Quand prendre vos suppléments

Le moment de la prise compte pour certains suppléments et beaucoup moins pour d'autres. En bref : prenez la créatine à n'importe quel moment de la journée (la régularité prime sur l'heure) ; la caféine et les pré-entraînements 30 à 45 minutes avant l'effort et pas trop tard en journée ; les électrolytes pendant ou après l'exercice ; le magnésium et la mélatonine le soir avant le coucher ; et les protéines et collations protéinées quand cela vous convient pour atteindre votre cible quotidienne. Tous les produits recommandés sur cette page sont en stock et expédiés le jour même depuis Montréal, avec livraison gratuite sur les commandes admissibles partout au Canada et aux États-Unis.
