Why it matters

Metabolic decline is quiet. Until it isn't.

01

Energy starts here

Vitamin D, B12, and iron drive how energized you feel.

02

Mood and mind

B-vitamins and vitamin D quietly shape mood, focus, and sleep.

03

Fixable fast

Most deficiencies correct within weeks once you know the right form and dose.

About 10 to 12 days after your draw, a Rethryv physician sits down with you, on video, and reads your results together. What's strong, what to watch, and exactly what to do next. It's included free, and it's the part most people remember.

Questions

Good to know.

Do I need to fast?

A morning, fasted draw gives the cleanest iron and vitamin readings. We'll send clear prep instructions when we schedule you.

Is the physician call included?

Always. Every panel includes a free, live review call with a Rethryv physician. There's no upsell to talk to a doctor, it's the foundation of how we work.

Can I combine with other panels?

Yes, and you should. Add any other panels to your cart and we'll combine everything into one blood draw, so you're only stuck once.

How soon can I improve these numbers?

Most nutrient deficiencies respond within a few weeks of the right form and dose. Your physician will map out exactly what to take and when to retest.

What will I walk away with?

A clear read on your foundational nutrient levels, the specific markers to watch, and a personal plan, including which supplements, if any, would move your numbers.
