What to expect
Days 1–7
Subtle shifts
Some people notice reduced reactivity and slightly better sleep. Others feel nothing yet — this is normal. The foundation is building.

Calm sets in
Most people notice reduced stress reactivity — situations that would normally trigger a stress response feel more manageable and less consuming.
Weeks 3–4
Energy balances
Steady natural energy without the 3PM crash. Focus improves. Sleep quality deepens. The tired-but-wired feeling begins to resolve.
Weeks 5–6+
Full baseline
Mood, energy, stress resilience and sleep all working together. Most people describe feeling like a more balanced version of themselves.
Why KSM-66® matters
Not all ashwagandha is
created equal.
Most ashwagandha supplements use leaf extract, root powder, or unspecified plant parts. KSM-66® uses only the full-spectrum root — the most potent, most studied, and most bioavailable form — standardised to 5% withanolides for consistent, measurable results.
It is the most clinically studied form of ashwagandha in the world. Over 24 published gold-standard studies. Not marketing language — peer-reviewed evidence.

Frequently asked questions
Everything you need to know about KSM-66® Ashwagandha
Most ashwagandha supplements use leaf extract, unspecified plant parts, or root powder with no standardisation. KSM-66® uses only the full-spectrum root extract standardised to 5% withanolides — the active compounds responsible for ashwagandha's benefits. It is the most clinically studied form with over 24 published gold-standard trials backing its efficacy. Generic ashwagandha delivers inconsistent potency. KSM-66® delivers a precise measurable dose every time.
Most people notice subtle changes in stress reactivity within the first 1–2 weeks. Energy balance and sleep improvements typically follow in weeks 3–4. Full benefits — calm, sustained energy, improved focus and sleep — build over 5–6 weeks of consistent daily use. Ashwagandha is an adaptogen not a stimulant. It works cumulatively not instantly. Consistency is everything.
No. KSM-66® Ashwagandha is not a sedative and does not cause drowsiness or impair function. It works by regulating your cortisol and stress response so you feel calmer and more balanced not sedated. Most people report feeling clearer and more focused not foggy or tired.
Both work. Morning dosing supports calm focus and sustained energy throughout the day. Evening dosing supports relaxation and natural wind-down before sleep. Take 2 capsules once daily with or without food. Consistency matters more than timing — the same time each day helps your body build a reliable baseline response.
Yes. KSM-66® Ashwagandha has been used safely in clinical studies for extended periods. It is non-habit forming and does not create dependency. As with any supplement if you are pregnant, breastfeeding or taking medication consult your healthcare provider before starting.
Yes. Ashwagandha KSM-66® pairs particularly well with Magnesium Glycinate — ashwagandha supports your daytime stress response and energy while magnesium supports nighttime muscle relaxation and sleep quality. Together they address both sides of the stress and recovery cycle. Consult your healthcare provider if taking prescription medication.
The formula combines 600mg KSM-66® Ashwagandha with L-Arginine 300mg for circulation support, Maca Root 150mg for natural vitality, Panax Ginseng 100mg for cognitive function, Shatavari 50mg for hormonal balance, plus Vitamin D3, B6 and B12 for nervous system and energy support. A complete multi-ingredient adaptogen formula — not just a single herb in a capsule.
2 capsules per serving, 30 servings per bottle, 60 capsules total. Take 2 capsules once daily. One bottle covers 30 days. For best results we recommend starting with a 60-day supply — benefits build cumulatively and the full effect is typically felt between weeks 4 and 6.
