What it is
A proprietary evening blend of magnolia bark (standardized to honokiol), epimedium, L-theanine from green tea, plant sterols (with beta-sitosterol), and phosphatidylserine, taken with the evening meal. It is built to support the body's normal, healthy stress-response rhythm and steady cortisol handling rather than to sedate you. It contains soy.
Why the evidence supports it
Stress physiology runs through cortisol, and this blend works it from a few angles at once: phosphatidylserine and beta-sitosterol are the ingredients most studied for helping the body manage cortisol around stress and exercise, while L-theanine is the best-supported calming compound here, with human research on relaxed, focused alertness. The honest read is that it is a proprietary blend, so not every per-ingredient amount is disclosed, and the strongest single-active evidence sits with L-theanine. Taken together, that is an evidence-based way to support the nervous system's normal downshift -- the Mind's Regulate function -- through a stressful stretch, not a lever that lowers a lab value.
What it supports
- Supports the body's normal, healthy stress response
- Supports a calm, settled state in the evening
- Provides L-theanine, a calming amino acid found in tea
- Complements good sleep, movement, and everyday stress habits
Which function it supports
Ties to the Mind world's Regulate function -- supporting the nervous system's normal downshift as the day winds down. This is stress-response support only, not a treatment for any condition.

The science on the ingredients
If you have had labs done
These are lab markers where this product's ingredients have measured evidence in our citation library. This is not a claim that the product will change your results -- the research attaches to the ingredient, and what a marker means depends on the whole picture. Each one links to its full entry, including what typically moves it and how to read it.
- Cortisolsolid evidence
via L-Theanine · 10 studies, 8 in people
What people often notice when this marker sits outside the usual range
Higher: "Wired but tired" -- exhausted all day, then alert the moment the head hits the pillow.
Lower: Profound fatigue that is worst in the morning, and improves slightly through the day -- the reverse of the usual pattern.
via Beta-sitosterol/plant sterols · 6 studies, 3 in people
What people often notice when this marker sits outside the usual range
Higher: The symptoms that actually travel with raised triglycerides belong to the metabolic pattern behind them -- the post-meal crash, central weight, rising blood pressure, fatty liver.
Lower: Very low total cholesterol alongside low albumin and unintended weight loss points at absorption or liver capacity, not at good health.
- LDL-C (LDL Cholesterol)solid evidence
via Beta-sitosterol/plant sterols · 6 studies, 3 in people
What people often notice when this marker sits outside the usual range
Higher: A high LDL-C is an ESTIMATE that a lot of cholesterol cargo is riding in your LDL particles.
Lower: A low LDL-C is generally favourable, but on its own it is a start, not an answer -- pair it with ApoB to know the real particle burden.
- Total Cholesterolsolid evidence
via Beta-sitosterol/plant sterols · 6 studies, 3 in people
What people often notice when this marker sits outside the usual range
Higher: A high total cholesterol is silent and, on its own, can be actively misleading -- it blends favourable HDL and atherogenic LDL/particle cholesterol into one crude figure.
Lower: A low total cholesterol is likewise uninformative alone -- the meaning is entirely in the breakdown.
- Apolipoprotein B (ApoB)solid evidence
via Beta-sitosterol/plant sterols · 1 studies, 1 in people
Competes with cholesterol for intestinal absorption; roughly 5-15% lower LDL-C and ApoB at about 2 g/day.
What people often notice when this marker sits outside the usual range
Higher: Visible lipid deposits -- tendon xanthomas, a corneal arcus before about age 45 -- are rare but meaningful, and they point at inherited familial hypercholesterolaemia rather than at diet.
- Non-HDL Cholesterolemerging evidence
via Beta-sitosterol/plant sterols · 6 studies, 3 in people
What people often notice when this marker sits outside the usual range
Lower: A low non-HDL is favourable and, unlike calculated LDL-C, stays reliable even when triglycerides are high.
- ApoB (Apolipoprotein B)emerging evidence
via Beta-sitosterol/plant sterols · 1 studies, 1 in people
What people often notice when this marker sits outside the usual range
Higher: A high ApoB means a high NUMBER of atherogenic particles in circulation -- the count that actually tracks risk.
Lower: A low ApoB means few atherogenic particles.

No product works in isolation
Every cell function above -- Sense, Exchange, Transform, Build, Maintain, Adapt -- needs the same broad base of optimal micronutrient levels running underneath it, all the time. Cortitrol is not a stand-alone fix; it is one piece that plugs into that larger system. The foundation comes first, and this supports it.

Foundational, or targeted?
Not everything in the shop is meant to be taken forever. Some products here are foundational -- a daily nutrient base built for long-term, ongoing use. Others are targeted -- shorter-term support for a specific season, not a lifelong habit. If you are not sure which one this is, that is a fair question to ask us before you buy.

Cortitrol is a modest evening blend of magnolia bark, L-theanine, plant sterols, and phosphatidylserine, taken with the evening meal. It is designed to support the body's normal, healthy stress-response rhythm rather than to sedate you. It suits people looking for gentle support through a stressful stretch.
FAQ
What does Cortitrol support?
It supports the body's normal, healthy stress response and a calm, settled state in the evening, provides L-theanine (a calming amino acid found in tea), and complements good sleep, movement, and everyday stress habits.
How do I take it?
Take two capsules with the evening meal. The label allows an optional additional capsule with breakfast for some people. Follow the current bottle.
What makes it different?
It is a proprietary blend, so the framing stays modest on purpose. The strongest single active is L-theanine, which has calming research behind it, so it is gentle stress-response support rather than anything that lowers a lab number.
