So I made this.

The Supplement Quick Reference Card — a free, printable PDF that puts everything on one page:

  • Exact daily doses for all 4 supplements

  • Which forms to buy (and which to avoid)

  • Morning vs. evening timing schedule

  • The cofactors most people forget

  • Optimal blood test ranges

  • Recommended products with links

  • Total cost: $34-68/month

No fluff. No 40-page deep dive. Just the essentials at a glance.

The reference card gives you the "what." If you want the "why" — the clinical trials, the mechanisms, the interaction warnings, the stacking strategies — The Essential Supplement Stack Guide goes 40+ pages deep.

One more thing: If you found this useful, forward this email to one friend who's spending money on supplements without a clear plan. They'll thank you for it.
