Do I need supplements?
Short answer first. Full logic in the chapter.
No supplement will fix a broken system. But a few are worth considering once your foundation is solid:
Worth it:
- Creatine monohydrate (5g/day) — the most researched supplement in history. Improves strength, recovery, and lean mass. Cheap, safe, effective.
- Vitamin D (if you live in a northern climate) — critical for hormone function
- Omega-3 fish oil — supports brain health and reduces inflammation
- Magnesium — most people are deficient; helps sleep quality
Skip entirely:
- Fat burners — caffeine with a markup
- BCAAs — useless if you eat adequate protein
- Detox teas — expensive laxatives
- "Metabolism boosters" — marketing, not science
The rule: Supplements are the last 2%. The first 98% is protein, deficit, sleep, and walking. Don't optimize the garnish while the foundation is crumbling.
The book doesn't sell supplements — it sells understanding.
