What is Keyspan?
Keyspan was conceived with a clear vision: to empower people to achieve prolonged, vibrant health.
We transform the often complex process of health optimization into a personalized, simplified, and fun journey to fast-track your health with ease.
How does a Keyspan membership work?
Keyspan membership costs:
Monthly: $199/month
Annual: $1999/year ($167 per month), and includes the following:
A comprehensive Baseline Blood Test, personalized diet, lifestyle, supplement and exercise plans, blood draws every 6 months and one-on-one health coaching. It also includes monthly deliveries of personalized supplements, along with continuous monitoring, support, and reminders via the Keyspan app.
Who is Keyspan for?
Keyspan is designed for anyone committed to optimizing their health. Whether you're aiming for improved mental and physical performance, weight loss, stress reduction, better sleep, or even prevention of chronic diseases. Our goal is to empower you with personalized insights and tools to achieve and maintain optimal health.
To subscribe to Keyspan you must be over 18 years of age, live in the United States, and have an Android or iPhone in order to access the app.

What biomarkers do you test?
Blood biomarkers offer a crucial understanding of your metabolic health and nutritional condition, assisting in identifying potential nutrient deficiencies and disease risk. At Keyspan, we examine the following:
Baseline test for men:
Glucose, Hemoglobin A1c, Cholesterol, HDL, LDL, Triglycerides, ApoB, Calcium, Vitamin D, Testosterone, Cortisol, Albumin, Magnesium, Folate, Vitamin B12, RDW, Iron, Hemoglobin, Potassium, CRP, Homocysteine, GGT, AST, ALT.
Baseline test for women:
Glucose, Hemoglobin A1c, Cholesterol, HDL, LDL, Triglycerides, ApoB, Calcium, Vitamin D, Testosterone, Cortisol, Albumin, Magnesium, Folate, Vitamin B12, RDW, Iron, Hemoglobin, Potassium, CRP, Homocysteine, GGT, AST, ALT, Estradiol and TSH (Thyroid).
Initial blood draws are collected at home (or a place of your choosing) with a mobile phlebotomist. At the 6 month mark, we do another followup blood draw to fine tune the plan.
Is Keyspan comprehensive for women & men’s health?
We cater to the distinct metabolic and hormonal differences between men and women, this way plans and recommendations can be further tailored to the individual based on their unique physiology.
What’s Keyspan’s methodology for ranges? How does this differ from what I might find elsewhere?
Our method for ranges is to shift the range of western medical “normal” to a more functional range, flagging on-edge biomarkers as opportunities to prevent reds. Western medical range samples are taken from the majority, not from the healthy.
Why is my first month $299 if I live in NY/NJ/RI?
Due to state-specific costs, customers in NY, NJ, and RI pay a one-time additional fee during their first month. This fee covers additional regulatory and logistical costs. After the first month, your subscription is the standard $199/month.
What is Truemed?
Truemed makes it easy to use your Health Savings Account (HSA) or Flexible Spending Account (FSA) dollars for Keyspan products and services. They handle the paperwork, including Letters of Medical Necessity (LMNs), so you can save money by using pre-tax dollars.

Direct Payment: You can pay directly with your HSA/FSA card at checkout.
LMN Required: Any product or service that involves supplements requires a Letter of Medical Necessity (LMN). Truemed makes this quick and easy during checkout.
