How to Measure Your NAD⁺ Levels

Summary: If you’re starting VITALIZE, get a baseline now, follow a steady morning routine for 8–12 weeks, then re-test. You’ll see the number move and you’ll feel it in steadier daytime energy and recovery. Longevity starts with clarity.

Who this helps: Anyone in their 30s–60s+ who wants objective proof that their AM routine and habits are rebuilding a healthier NAD⁺ reserve.

Why measure at all

NAD⁺ supports energy production and cellular upkeep. Levels usually decline gradually with age; the shift is slow enough that you can feel a little less steady without knowing why. A simple blood test gives you clarity on whether NAD⁺ is part of the picture. Start with a baseline, act consistently, then re-measure — measure → act → measure. Seeing the number move alongside how you feel turns your routine into evidence.

What you’ll typically notice by three months

With steady sleep, movement, and daily VITALIZE, many people describe more even daytime energy, lighter mornings, and smoother recovery by about eight to twelve weeks. Use your re-test to confirm the direction, and your notes to interpret the change.

The quick plan

• Day 0: Take a baseline NAD⁺ test in the morning before food or supplements, then start VITALIZE the same day.
• Weeks 1–4: Keep the routine identical each morning; protect sleep and daytime light.
• Week 4 check-in: Note real-world signals such as mid-afternoon energy, training recovery, and sleep stability.
• Weeks 8–12: Re-test on a comparable morning before food or supplements.
• After retest: Compare numbers and notes; keep what’s working and adjust what isn’t.

How to take the blood test

Use the at-home kit on a weekday morning before food, coffee, or supplements. Wash hands, warm the finger, collect the sample, and post it the same day. Results typically arrive 5–7 business days after the lab receives your sample. Processing is handled by a certified EU lab with GDPR-compliant data handling. On test days only, take VITALIZE after sampling.

How to read your results

You’ll get a typical NAD⁺ range for your age—use it as a benchmark, not a diagnosis. Take a clean baseline, then re-test after 4 weeks (and again at 8–12) to see movement. In this example, the results moved from 12 → 26 µmol/L after 4 weeks of taking VITALIZE.  Look for an upward trend into or toward your age range rather than a single “perfect” number.

What to track alongside the blood test

Numbers are helpful, but context matters. Keep brief daily notes on:

• Afternoon alertness
• Post-workout recovery time
• Sleep quality and timing
• Morning resting heart rate or HRV (if you track it)
• Nights with alcohol or very late meals

You will see patterns emerge that explain the number and help you make better choices the next eight weeks.

Where VITALIZE fits

Lifestyle keeps you efficient; VITALIZE keeps you sufficient. Take it each morning at the same time. If you fast, take it with your first meal. The design is straightforward: build with NMN, help protect NAD⁺ from needless breakdown with apigenin, and support recycling with TMG. Most people notice smoother daytime energy in two to four weeks, with clearer changes by eight to twelve.
