GRN Labs Blood Flow Health Protocol

Your blood flow baseline is a number
your annual physical never gave you.

Your health check gives you a starting point. The paid protocol turns that baseline into a weekly plan across food, movement, sleep, and supplement education. At 90 days, you repeat the check and compare the same signals.

Because a baseline is only useful when you know what to do next.

The protocol starts from your health-check answers. Lab work can add context later.

This is what your protocol builds from your baseline.

Your answers set the starting point. The protocol gives you specific weekly actions and a cleaner way to review progress.

Your baseline should lead to a plan.

01
You came here from the health check with a baseline.
You may already track blood pressure, sleep, activity, or performance. The missing piece is a simple plan built around the pattern in those answers.
02
Data without a plan becomes another thing to manage.

Generic trackers can give you more numbers than direction.

Routine visits may not give you a weekly plan.

Search results can leave you with too many conflicting ideas.

The Blood Flow Health Protocol gives you a tighter loop: baseline, weekly actions, tracking, then a day-90 comparison.

03
The next question is what to do first.

A recommendation list is general. A protocol gives you weekly focus, simple tracking, and education based on your Health Check profile.

Fifteen factors evaluated.

One blood flow baseline.

One protocol mapped to yours.

Reviewed again at 90 days.

Side by side

What this gives you that your physical does not.

A physical answers medical questions. The protocol gives you a weekly education and tracking structure.

How it works

The loop that keeps the plan specific.

Your baseline sets the starting point. Weekly tracking helps the protocol stay focused on what changed and what still needs attention.

Step 01

Your baseline

Your health-check result becomes the starting point. The highest-impact factors are visible so you can see what shaped your estimate.

Step 02

Your protocol

Four domains, built around your Health Check profile. Each recommendation links to the research behind it and includes safety notes where needed.

Protocol / Week 1
Nutrition 3 actions
Lifestyle 2 actions
Exercise 2 actions
Supplements 1 action
Step 03

Your checkpoint

At 90 days, you repeat the same health check. The protocol shows which tracked answers changed and what still needs attention. Optional lab work can add context later.

The protocol

Built from your assessment profile. Updated when lab data is added.

Most health advice applies to everyone. This starts with your baseline. The protocol organizes your next actions across food, movement, sleep, and supplement education.

Your protocol starts with your assessment inputs. When you add lab results, the protocol becomes more precise.

The feedback loop

How the day-90 checkpoint works.

Track your baseline, follow the protocol, then repeat the health check at day 90.

Days 1–30

Set your baseline

Start with your health-check answers. Track the factors that matter for your profile.

Days 30–60

Follow the protocol

Use the weekly plan and keep tracking your health signals over time.

Days 60–90

Repeat the health check

Compare your current answers with your starting point. The new GRN estimate shows what moved.

Before supplement guidance

Supplement guidance starts with a safety screen.

Before supplement guidance is shown, GRN asks about medications, health conditions, and relevant safety factors. If your answers suggest a possible concern, GRN may recommend that you consult your own healthcare provider before beginning the protocol. GRN does not contact providers on your behalf.

How we compare

The difference is not the price.

The real difference is what happens after the measurement.

Questions

Good ones, answered.

What if my standard bloodwork is already normal?

A standard lipid panel and the GRN Blood Flow Health Check answer different questions. The health check uses self-reported factors to build an educational baseline. Lab work can add clinical context when appropriate.

How is this different from Googling supplement stacks?

A Google search returns population-level research. GRN Labs maps your 15-factor profile to weekly guidance with safety notes and citations. The 90-day checkpoint helps you compare the same signals again.

Will this work if I'm already on blood pressure medication?

GRN Labs works alongside existing care. If you take blood pressure medication or have a medical condition, use the protocol as educational context and review changes with a qualified clinician.

What happens after 90 days?

You repeat the 15-factor health check. Your GRN estimate updates based on your current answers. Your subscription continues with an updated plan and a new day-90 checkpoint.

What if my vascular age does not improve at 90 days?

The repeat health check shows which tracked answers changed and which stayed flat. That information helps shape the next checkpoint. GRN Labs does not promise a specific number.

Is GRN Labs a substitute for seeing my doctor?

No. GRN Labs is a wellness education service. It is not a medical service and does not provide diagnoses. It can help you organize information for a more specific conversation with a qualified clinician.

How does the protocol assignment work?

Your 15-factor score maps to a Blood Flow Health profile based on your answer pattern. Each profile has a corresponding protocol with weekly focus guidance, supplement education, safety notes, and a tracking cadence. It is not a diagnosis.

What is the cancellation policy?

You can cancel your subscription at any time before the next billing cycle. There are no contracts and no long-term commitments.
