Question 1

What's included in the Vitamin & Mineral Panel?

Accepted Answer

[Vitamin D](/tests/vitamin-d), [Vitamin B12](/tests/vitamin-b12), Folate, Magnesium, Zinc, [Ferritin](/tests/ferritin), Calcium, Selenium, Copper. 9 individual tests covering the major nutritional markers that affect energy, immune function, hair health, and athletic performance.

Question 2

Which deficiencies are most common?

Accepted Answer

In our user base: Vitamin D (40-50% of adults), B12 (especially vegans/vegetarians and those over 50), Iron/Ferritin (menstruating women, endurance athletes), Magnesium (>60% of US adults have suboptimal intake), Zinc (vegans, athletes). This panel catches all of the high-prevalence deficiencies in one draw.

Question 3

How is this different from the Basic Vitamin Deficiency Panel?

Accepted Answer

[Basic Vitamin Deficiency Panel](/tests/vitamin-deficiency-panel) at $89.99 is focused on the three core vitamins (D, B12, Folate) — 3 tests. Vitamin & Mineral Panel at $189 adds the minerals (Magnesium, Zinc, Calcium, Selenium, Copper) for a complete micronutrient picture. Use Basic Vitamin Deficiency for a quick fatigue workup; Vitamin & Mineral for full nutritional assessment.

Question 4

How much does the Vitamin & Mineral Panel cost without insurance?

Accepted Answer

On TestWell, the Vitamin & Mineral Panel is $189.99. Ordering the same 10 tests separately would be about $280. Quest Direct lists comparable bundles at $350, walk-in hospital labs typically bill $800-1200 for the same biomarkers without insurance.

Question 5

Do I need to fast?

Accepted Answer

Yes — 8-12 hours of fasting (water only) for accurate ferritin, calcium, and magnesium readings. Also hold any vitamin/mineral supplements for 24 hours before to avoid artificially elevated results.

Question 6

When should I retest after supplementation?

Accepted Answer

Vitamin D: 8-12 weeks after starting/changing dose. B12: 6-8 weeks. Iron: 8-12 weeks (ferritin responds faster than hemoglobin). Magnesium and zinc: 8 weeks. Always retest before increasing supplement doses to avoid toxicity (especially with iron, selenium, and copper).

Question 7

Should I add Omega-3 Index?

Accepted Answer

Yes if longevity-focused. Omega-3 Index >8% is associated with the lowest all-cause mortality in long-term studies. Most Americans are below 4%. Not included in this panel — order separately if interested.
