Nutrition Testing

(via 5Strands)

Simple kit • Private results • Clear actions you can take

What this test tells you

Instead of guessing which supplements are “working,” this at-home kit shows how your body is responding to key vitamins, minerals, amino acids, and fatty acids. If absorption is off—because of stress, inflammation, gut issues, or poor-quality forms—the report flags it so you can adjust with confident, targeted choices.

  • Action-ready results you can use to refine food and supplement choices.
  • Private & secure: results are shared with the participant only.
  • Fast turnaround: typical delivery within 4 business days of lab receipt.

Educational use only — not a diagnosis, treatment, or medical service.

Green — Mild

Lower response. Monitor while you focus effort on Red/Yellow items.

Grey — Not Flagged

Below response threshold. No current action suggested.
