Nutrient Imbalance Testing

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.

Yellow — Moderate

Intermediate response. Good next targets once high-priority items are addressed.

Green — Mild

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

Grey — Not Flagged

Below response threshold. No current action suggested.

Get Results in 4 Easy Steps

Quick to do — clear to understand.

  1. Register your kit

    Go to 5Strands.com (or the mobile app) and enter the unique ID inside your box.

  2. Collect a small hair sample

    Snip 10–15 strands from head, arm, or body. The root isn’t required.

  3. Mail your sample

    Place the hair in the provided bag and return it using the kit packaging.

  4. Receive your results

    Results typically arrive within 4 business days after the lab receives your kit.

Turn Insights Into Better Daily Choices

Use the report to refine food, timing, and supplement form.

Refine your diet

Prioritize nutrient-dense whole foods aligned to your flagged items. For example, magnesium-rich leafy greens, pumpkin seeds, and cacao can support low magnesium patterns.

Optimize supplements

Choose bioavailable forms (e.g., methylated B-vitamins, chelated minerals) and sensible timing to support absorption and optimize nutrient supplementation.

Reduce blockers

Inflammation, intolerances, and certain synthetic additives in supplements may interfere with proper utilization. Addressing triggers can improve response.

Pairing this with a Food Intolerance screen can reveal links between sensitivities and nutrient use.

Your Privacy Comes First
