What made this different was having both the numbers and the next step. I re-tested after a month and my microplastics load went from moderate to low. That was the first time I've seen clear proof something like this worked for me.

Keyspan is amazing. Its so simple, just wake up, get your actions for the day and go! I uploaded my labs and Kai made it easier to understand what to actually do about them. Kai tracked everything for me and gave me 4–5 simple things to focus on each day based on my labs, my wearables, and my schedule. Oh, the supplements made a bigger difference than I expected.

My aha moment was realizing I didn’t have to figure all of this out on my own anymore. Keyspan handled the blood draw at home, my coach helped me understand the bigger picture, and Kai gave me a simple action list every morning. The supplements were built for me, the plan fit into my real life, and it finally felt like I had a full team helping me achieve my health goals.

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.

LMN Required: Any product or service that involves supplements requires a Letter of Medical Necessity (LMN). Truemed makes this quick and easy during checkout.
