Understanding Vitamin Panel: Normal vs Optimal Ranges

?What is a Vitamin Panel?

A Vitamin Panel measures essential vitamins in your blood that are critical for energy, immunity, bone health, and neurological function. It detects deficiencies that cause fatigue, poor immunity, bone loss, and cognitive decline — often before symptoms appear.

What Does It Measure?

• Vitamin D (25-OH) — bone health, immunity, mood regulation
• Vitamin B12 — nerve function, red blood cell production, DNA synthesis
• Folate (B9) — DNA synthesis, red blood cell production, fetal development
• Vitamin B6 — neurotransmitter synthesis, immune function
• Vitamin C — antioxidant, immune support, collagen synthesis
• Vitamin A — vision, immune function, skin health
• Vitamin E — antioxidant, cell membrane protection

!Why It Matters

Vitamin deficiencies are epidemic — 42% of adults are vitamin D deficient, 20% are B12 deficient (higher in vegetarians/vegans), and 15% are folate deficient. These deficiencies cause fatigue, depression, poor immunity, and increased disease risk. Most are easily correctable with supplementation.

Component Breakdown

How to Prepare

• No fasting required for most vitamin tests
• Avoid biotin supplements for 2-3 days before test (can interfere with some assays)
• Tell your doctor about supplements — high doses can skew results
• Morning testing preferred for vitamin D (least variability)

What Do Results Mean?

Low vitamin D: bone loss, poor immunity, depression. Low B12: fatigue, neuropathy, anemia, cognitive decline. Low folate: anemia, birth defects (in pregnancy), elevated homocysteine. Low B6: depression, confusion, weakened immunity. Low vitamin C: poor wound healing, bleeding gums, frequent infections.

Next Steps

Deficiencies are treated with targeted supplementation. Vitamin D: 2,000–5,000 IU/day. B12: 1,000 mcg/day (oral or sublingual). Folate: 400–800 mcg/day. Retest in 2-3 months to confirm correction. Address underlying causes (diet, absorption issues, medications).
