Cortisol Awakening Response Research: Arjuna Natural’s Upcoming Shoden Study Explained

Jessie Cavanaugh of Nutraceuticals Analysis Institute and Keely Johnson of Arjuna Pure break down the science of cortisol awakening response, ashwagandha analysis methodology, and Shoden’s groundbreaking three-arm research on Episode #207 of the PricePlow Podcast.

0:00 – Introductions

Mike opens by welcoming two returning components and one first: Keely Johnson of Arjuna Pure (again from Episode #171), Jessie Cavanaugh of Nutraceuticals Analysis Institute in her podcast debut, and Victoria Johnson making her first PricePlow Podcast look. Victoria introduces herself as a registered nurse with almost 9 years of scientific expertise and a powerful curiosity in lifting and supplementation.

Keely reintroduces Arjuna Pure’s deal with Indian botanicals and branded substances, noting that the staff introduced Nutraceuticals Analysis Institute on particularly for brand spanking new Shoden analysis. Mike flags that cortisol awakening response would be the central thread and units up Jesse to take the ground.

1:45 – Jessie Cavanaugh’s Background

Jessie’s PhD dissertation was a scientific trial learning pre-procedural stress in kids on the autism spectrum, and she or he’s spent over 20 years within the pure merchandise {industry} as each educator and researcher. After finishing her doctorate, she went by way of Harvard Medical Faculty’s Scientific Students Coaching Program, which deepened her deal with methodology throughout the nutraceutical area. She now runs Nutraceuticals Analysis Institute, the place the only real focus is conducting high-quality, methodologically sound research for pure merchandise.

Her throughline: 20 to 30 years in the past, the issue was too little analysis on pure merchandise. At this time there’s extra analysis, however not essentially good analysis. That is the hole her lab targets.

3:00 – What Makes Good Nutraceutical Analysis

Jessie identifies two main methodological issues in nutraceutical analysis. First, many research are designed by individuals who weren’t educated in scientific analysis, producing outcomes that may’t distinguish sign from noise and sometimes fail to account for demographic variables like socioeconomic background or intercourse variations. Second, researchers steadily borrow end result instruments from the pharmaceutical {industry} (instruments constructed to measure sick folks getting effectively) which creates ceiling results when learning usually wholesome populations taking nutraceuticals.

Her repair: purpose-built psychometric instruments, correct end result endpoints, and controlling for the inhabitants quite than hoping the demographics even out. She virtually at all times runs female and male contributors individually as a result of “these variations are simply too massive.”

5:30 – Recruiting the Proper Research Inhabitants

When learning one thing like Shoden for stress, you need people who find themselves truly confused — not people who’ve already optimized their routines with breathwork, dietary supplements, and 5 years of stress-management habits. Jessie’s staff screens closely to seek out the best chronic-stress inhabitants, then makes use of superior statistics to regulate remaining variables quite than counting on easy t-tests.

She additionally flags a nuance that usually will get ignored: exclusion standards matter as a lot as inclusion standards. Somebody going by way of a divorce, for instance, introduces an excessive amount of unpredictable exterior noise. The aim is isolating that low-lying power stress that blunts the cortisol awakening response — not acute life disruptions that will swamp any intervention sign.

7:00 – Acute vs. Continual Stress

There are two flavors of stress: acute (state) and power (trait). Pre-procedural stress (the spike you are feeling earlier than a blood draw, a take a look at, or a surgical process) is acute and might truly be wholesome, constructing resilience when it does not go too excessive. Continual stress is the low-grade fixed load of recent life, the type that retains cortisol elevated in a single day and blunts the morning surge it’s essential to begin the day.

Jessie’s research on Shoden goal that power class, figuring out contributors whose cortisol hasn’t come down sufficient in a single day and whose awakening response is consequently blunted. She notes that acute stress is tougher to judge exactly as a result of the “proper” degree relies upon closely on the person and context.

11:15 – Cortisol: Past “The Stress Hormone”

Shoden brings a brand new period to ashwagandha dietary supplements with 35% glycowithanolide standardization. Analysis reveals it delivers highly effective results at simply 60-120mg each day, in comparison with 600mg+ with conventional extracts.

Cortisol will get a nasty repute, however Keely provides a private information level: about ten years in the past she examined her personal ranges by way of the Dutch take a look at (the one take a look at she’s conscious of that measures cortisol at a number of factors throughout a 24-hour interval) and located hers have been undetectable. That have reshaped how she thinks about stability versus suppression. The aim is not to eradicate cortisol, it is to have the correct quantity on the proper instances.

Jessie reinforces the physiology: cortisol ranges drop low throughout sleep whereas the physique runs its in a single day upkeep, then start rising simply earlier than waking in live performance with the lightening sky. Once more, the difficulty is not having cortisol, it is having cortisol in its appropriate rhythm all through the day.

13:45 – The Cortisol Awakening Response

Within the first half-hour after waking, a wholesome cortisol awakening response (CAR) produces a 50 to 80% spike from baseline. That surge is what prompts cognitive operate, clears mind fog, and will get the physique able to navigate the day. It is related to immune operate, vitality regulation, and even metabolic markers like sort 2 diabetes danger. Individuals with power stress usually see a blunted CAR — some contributors within the research have been solely hitting a 20% rise at baseline.

That is why measuring cortisol at a set clock time throughout all contributors is almost ineffective. You do not know for those who’re catching the height, the plateau, or the decline. Jessie’s protocol has contributors maintain a saliva vial on the bedside and acquire a pattern earlier than sitting up, then set a 30-minute alarm for the second pattern — no espresso, no breakfast, no toothbrushing in between. That dynamic captures the precise CAR.

18:00 – Research Protocol & Life-style Controls

Not all ashwagandha extracts are created equal. This information explains why standardization issues, why extract ratios could be deceptive, and find out how to establish high quality merchandise when looking for this well-liked adaptogen.

Caffeine definitively interacts with cortisol manufacturing, so contributors in Jessie’s research cannot have espresso till after each saliva samples are collected. Past that, the rule is easy: do not change something. If a participant was doing yoga or meditation earlier than the research, they maintain doing it. In the event that they weren’t, they do not begin. Any life-style change introduces noise that might swamp the Shoden sign.

The identical logic applies to cell telephones and blue gentle. Fairly than asking contributors to cease “doom-scrolling” earlier than mattress (which might itself alter cortisol) the research accepts real-world habits and focuses on isolating the ingredient’s impact. Victoria notes that misinformation round cortisol (significantly in girls’s wellness circles on social media) makes this sort of clear methodology much more worthwhile.

20:00 – The Three-Arm Shoden Research

The research (which hasn’t but revealed as of this recording in February 2026) enrolled girls aged 30 to 59 and used three arms: Shoden-R, Shoden root and leaf, and placebo. The dose was 60mg, which Keely notes is the bottom in the marketplace. The first end result was the cortisol awakening response. Outcomes confirmed no vital distinction between Shoden-R and Shoden, whereas each outperformed placebo, that means the water-soluble beverage-stable kind delivers the identical profit as the unique capsule kind.

Keely flags this as the primary botanical research on the earth to make use of correctly timestamped CAR measurement. Fairly than focusing on a particular cortisol quantity, the research was designed to carry the CAR into vary — whether or not a participant was too blunted or barely too elevated, the intervention moved them towards that fifty to 80% Goldilocks zone.

23:30 – Decentralized Research & Participant Compliance

Jessie attracts a transparent line between a decentralized research (click-to-consent, bundle mailed to your door, surveys stuffed out through app) and an in-person research. The Shoden CAR research was in-person, however she’s carried out each varieties. The issue with absolutely decentralized research is participant authenticity — put an Amazon reward card behind an app survey and you may entice folks gaming the system quite than following protocol.

Arjuna Pure’s Shoden-R ashwagandha simply received Ingredient Idol at SupplySide International 2025. The foundation-only extract is water-soluble, works at 60mg, and eventually makes ashwagandha viable in drinks, gummies, and RTD codecs.

Her answer for any research is relationship-based compliance. From the knowledgeable consent session onward, contributors are handled as collaborators, not topics. They perceive precisely why the protocol issues and generally self-organize to maintain one another accountable. The outcome: contributors contact the lab proactively once they miss a dose timing or deviate barely from protocol — which is exactly the form of information integrity that enables clear conclusions.

27:15 – Research Outcomes & the Blunted Cortisol Surge

Along with the cortisol biomarker, the research used psychometric instruments to evaluate perceived stress and captured secondary and tertiary outcomes together with sleep high quality — a pure downstream impact when CAR improves. Victoria asks whether or not subjective questionnaires have been included alongside the saliva samples, and Jessie confirms they have been, noting that psychometrics usually decide up real-world results {that a} single biomarker can miss.

On the blunted surge query: it sometimes occurs as a result of cortisol by no means absolutely dropped in a single day. Already-elevated baseline ranges do not have far to rise, resulting in wonky patterns all through the day — undetectable troughs or sudden spikes. The aim is that clear steep upturn within the morning adopted by a gradual descent, which is strictly what Shoden seems to help.

31:00 – Formulating with Shoden: Past Calm

Keely is direct: not all ashwagandhas are created equal, and Shoden is not only a calming ingredient. A pharmacokinetic (PK) research evaluating prime market manufacturers discovered Shoden nonetheless current within the physique at as much as 20 hours — longer than rivals — supporting the concept of sustained cortisol stability quite than acute suppression. She takes it earlier than exercises herself and describes the impact merely: “I am a greater human.” Not drained, not sedated — simply extra in a position to let stress roll off and focus.

Mike provides the testosterone angle: ashwagandha’s documented help for testosterone ranges seemingly runs a minimum of partially by way of cortisol discount, since power stress actively suppresses the physique’s potential to supply testosterone. That makes a case for Shoden in each day pre-workouts, not simply in sleep and restoration formulation.

34:00 – Shoden-R in Useful Drinks

Shoden-R is the water-soluble model of Shoden, with bitterness, style, and scent eliminated, making it absolutely practical in drinks at simply 60mg. Arjuna Pure’s glowing water demo at SupplySide International 2025 received the Ingredient Idol competitors for practical drinks, with judges commenting on how clear and easy-to-drink it was. Extra just lately, Shoden-R appeared at Expo West 2026 in glowing water, strawberry peach drinks, and orange mango chews.

What if one night formulation may deal with stress, sleep, AND hydration? Formulator’s Nook #22 designs a nighttime restoration powder with Shoden-R ashwagandha, glycine minerals, and sensible osmolytes. Will a model carry it to market?

No industrial drinks with Shoden-R have launched but, however Keely says formulators are actively working with it and reporting that it is easy to make use of and straightforward to taste on the low dose. Victoria raises the query of caffeinated drinks — Keely confirms somebody is already exploring it in an iced tea — and the consensus is that the beverage class is huge open, from grab-and-go RTDs at Complete Meals to comfort retailer cabinets.

37:00 – Cortisol Stability, Testosterone & Consistency

The larger-picture message from Jessie: Shoden works greatest as a preventive, modulatory each day behavior, not an acute stress-response software. Taking it solely while you really feel overwhelmed means you are at all times enjoying catch-up. Taking it constantly retains the cortisol rhythm secure, which in flip helps cognition, testosterone manufacturing, immune operate, and exercise high quality. That is the throughline — and it connects to why Formulator’s Nook #22 constructed a whole nighttime hydration and sleep formulation round Shoden-R.

Mike factors out that many within the fitness center neighborhood already take a pre-workout each day, exercise or not, and Shoden suits the identical utilization sample naturally. Getting it into that each day ritual — whether or not in a pre-workout, a multivitamin, or a beverage — is the place the long-term profit compounds.

40:30 – Sleep Hygiene, Shift Work & Every day Habits

Jessie’s most underrated sleep hygiene tip: maintain your sleep timing constant day after day. The physique runs on rhythms, and constant mattress and wake instances do extra for cortisol regulation than many of the noisier recommendation circulating on social media. She acknowledges this is not at all times accessible — Victoria, as a nurse, has skilled shift work firsthand — nevertheless it’s the best, most ignored variable.

Bennito Russo, Keely Johnson, and Nipen Lavingia from Arjuna Pure’s staff reveals the science behind Shoden ashwagandha’s superior bioavailability and their industry-leading botanical standardization on the PricePlow Podcast #171.

For shift staff, Keely’s suggestion is to deal with consistency of complement timing throughout your entire week, no matter which days are on or off. The adrenaline response in a demanding scientific surroundings will occur regardless, however supporting the physique biochemically on a each day schedule offers the adrenal system a greater basis.

44:30 – What’s Subsequent: Menopause Analysis, Publication & The Ebook

The Shoden CAR research is heading into peer overview and Jessie expects it to publish very quickly — she’s the lead creator. The subsequent research is already written: a menopause-focused trial, women-only once more, learning a extra concentrated age group than the 30 to 59 vary lined within the present work. Keely has a protracted checklist of analysis questions she desires to deal with, together with the connection between cortisol and irritation and the way Shoden impacts post-workout restoration.

Jessie additionally has a ebook popping out in summer season 2026: The Feminine Stress Response, masking the whole lot mentioned on this episode — sleep hygiene, ashwagandha, and sensible methods for cortisol regulation. She’s most energetic on LinkedIn. Mike closes out by teasing a possible product giveaway by way of PricePlow and BevLab, with Keely providing to ship Shoden-R drinks and chews to the neighborhood.
