About GRN Labs

GRN Labs (also known as Get Right Nutrition or GRN Research Lab) is a vascular health research platform. We measure the biomarkers that predict arterial aging, specifically the ones your annual physical was never designed to order.

The symptoms men notice first are indicators of how well the vascular system is working: declining energy, brain fog, changes in sexual function. GRN Labs measures the biomarkers that explain them.

We offer the GRN Vascular Review. This assessment measures biomarkers that standard blood panels do not include. From those results, we build a specific weekly protocol targeted at the endothelial glycocalyx and nitric oxide pathways — the systems that determine how well oxygen and nutrients reach every organ, including the brain.

The protocol identifies the mechanism. It targets it directly. Progress is verified at 90 days with retesting so you can see what changed and by how much.

The GRN Vascular Review is built for men over 30 who have noticed changes in energy, cognition, or sexual function. Most have already tried something — a supplement, a diet change, a platform — and still have no feedback loop to know if any of it moved their numbers.

They want something specific. A measurement, a targeted protocol, and a verified result.

We start with measurement. The Vascular Asset Report helps identify areas where your vascular markers may benefit from support. From there, we build a targeted protocol designed to support healthy function over 90 days.

Every 90 days, we reassess. You upload updated labs, and the protocol adjusts to reflect what changed. Each cycle builds a clearer picture of your vascular biology and sharpens the next set of targets.

Standard blood panels miss critical vascular indicators. Our assessment includes advanced cardiovascular biomarkers that most physicians never order:

• ADMA (Asymmetric Dimethylarginine). Measures endothelial dysfunction at the molecular level
• ApoB. More accurate cardiovascular risk predictor than LDL cholesterol alone
• Lp(a). Genetic risk factor that standard lipid panels overlook
• hs-CRP. Inflammatory marker tied to vascular health
• Homocysteine. Amino acid linked to endothelial damage when elevated

The ADMA test is particularly significant. ADMA is an endogenous inhibitor of nitric oxide synthase the enzyme that produces nitric oxide. Elevated ADMA levels indicate your body is actively suppressing its own nitric oxide production. This insight guides our protocol customization in ways that symptom-based approaches cannot match.
