Benefits

Keyspan Precision Supplements are scientifically designed for each individual based on their biomarker data, health profile, and personalized needs.

No two packs are the same. Instead of taking a generic multivitamin or guessing which supplements might help, your daily pack is built around what your body actually needs support with — based on your data.

Each pack is designed to help support targeted areas such as nutrient status, metabolic health, inflammation, recovery, energy, hormone balance, heart health, and overall wellness.

By taking supplements matched to your biomarkers, you know you are giving your body support where it needs it most. And by retesting your biomarkers over time, you can see how your body is responding and track measurable progress.

Keyspan also makes supplementation simple. Each daily pack is pre-sorted and ready to go — no bottles, no pill organizers, no guessing. Just grab one pack a day and stay consistent.

Our packaging also uses 80% less plastic than traditional supplement bottles, making your daily routine simpler and more sustainable.

How to use

Take one personalized supplement pack daily with food and a full glass of water, unless otherwise directed by your healthcare provider.

Each pack is designed for one day of use and contains the supplements selected for your individual biomarker profile. Simply grab your daily pack, take it with a meal, and continue consistently as part of your routine.

For best results, use your supplements daily and retest your biomarkers as recommended. Retesting helps show how your body is responding over time and allows your supplement protocol to be adjusted as your needs change.

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.
