The cortisol crisis

of UK adults experience physical symptoms caused by chronic stress every single month.
01Chronic stress is rewiring your brainSustained high cortisol physically changes the brain — impairing memory, focus, and emotional regulation. It is not about willpower. It is about biology that needs to be addressed at the source.
02Your nervous system is stuck in overdriveModern life keeps cortisol elevated around the clock. The result: poor sleep, racing thoughts, low energy, and an inability to switch off — even when the pressure has gone.
03Not all adaptogens are equalKSM-66® is the world's most studied ashwagandha extract — backed by 24 clinical trials. Generic root powder contains a fraction of the withanolides that produce real results.

The daily ritual
How to
take it.
take it.
01
Take 1 capsule with foodOnce daily, morning or evening. Morning for all-day calm — evening if your primary goal is deeper sleep. Consistency matters more than timing.
02
Take it every day without failAshwagandha is adaptogenic — it builds in the body over time. Daily consistency is what creates the sustained cortisol regulation that makes the real difference.
03
Notice calmer evenings within 2 weeksMost customers report reduced reactivity to stress within the first two weeks. The full benefit — lower baseline cortisol and improved sleep — builds over 4–8 weeks.
04
90 capsules. Three months uninterrupted.Adaptogens need time. Three months of consistent use builds the neurological resilience that keeps you calmer under pressure.

Frequently asked
Questions,
answered.
answered.
How long until I notice the benefits?+
Most customers notice changes in stress reactivity within 2-3 weeks. Lower baseline cortisol and improved sleep become distinct around week 4. Full clinical effect is typically established by week 8. Consistency matters more than anything else.
Morning or evening - when should I take it?+
Both timings are clinically validated. Morning works well for all-day stress resilience. Evening works well if your primary goal is deeper sleep. Choose what fits your routine and stay consistent.
Can I take it with coffee or other supplements?+
Yes. There are no known interactions with caffeine. Ashwagandha pairs naturally with Magnesium Glycinate in the evening for complete stress, sleep and recovery support. It also combines well with Lion's Mane as part of the Stress and Focus Stack.
What makes KSM-66 different from regular ashwagandha?+
KSM-66 is a full-spectrum root extract standardised to a minimum of 5% withanolides - the bioactive compounds responsible for stress regulation. It is the world's most clinically studied ashwagandha extract, with 24 published human trials. Generic ashwagandha is typically unstandardised root powder with no verified withanolide content.
Is it safe to take long-term?+
Yes. KSM-66 has been studied in clinical trials up to 60 days with no adverse effects and is considered safe for extended use in healthy adults. It is not habit-forming. Consult a healthcare professional if you take prescription medication, are pregnant or breastfeeding, or have a thyroid condition.
What if it does not work for me?+
If you do not feel calmer or more resilient within 30 days, contact us at hello@elysium-supplements.com and we will make it right. Our 30 Day Calm Guarantee covers the full bottle, no questions asked.
