I've spent years being mindful of what goes into my body. But what you can't see matters just as much. That's why I believe in measuring, not guessing.

The 3-Phase Detox System

The Science

The 3-Phase Detox System

Phase 1: Activate

Your liver breaks compounds down into reactive intermediates. Antioxidant support helps protect liver cells during this step.

ALA • Milk Thistle

Phase 2: Neutralize

Your liver binds those intermediates to make them water-soluble and safe to excrete. This step needs building blocks and cofactors.

NAC • Zinc

Phase 3: Eliminate

Neutralized compounds exit through bile, stool and urine. A healthy gut lining keeps them moving out rather than being reabsorbed.

Probiotic • Omega-3

Results you can feel - and See

  • Feeling heard

    I get a lot out of my coaching calls. I feel like I've got a rapport with you, and you know what you're doing.

    Annalise B.in her 50s

    I already feel better, calmer, and more centered, and we are just at the beginning.

  • Tools

    I can ask Kai questions like, what's that mean, or how's it been trending recently. It's definitely been a useful tool.

    Michael L.in his 30s
  • Lena B.in her 40s

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.
