Full-Spectrum Ashwagandha KSM-66 extract uit de wortels van het kruid. Dit is de best opneembare vorm. Ik gebruik het voor betere slaap. Je moet het wel over een wat langere periode gebruiken om resultaat te merken. Zeer zuiver deze van clearly.

Clearly Ashwagandha is KSM-66®, an organic full-spectrum extract of the ashwagandha root (Withania somnifera), in a plant-based capsule. 500 mg per capsule, 60 capsules per pouch.
What's in a capsule
500 mg KSM-66® organic ashwagandha root extract, standardised to 5% withanolides and less than 1% withaferin A. The capsule is hypromellose (plant-based); organic rice starch and organic MCT powder fill it evenly.
Where it comes from
Ashwagandha is a small shrub from India, where its root has been used in Ayurveda for thousands of years. KSM-66® is made in India from the root only, with a water-based process and no added solvents, and is the most studied branded ashwagandha extract.
Why the root only
Many extracts are made partly from leaves, which are cheaper. The leaves hold more withaferin A and a different profile of compounds. KSM-66® uses only the root, so the extract keeps the full spectrum of the root's own compounds, in their natural proportions.
How to take it
1 to 2 capsules a day with a glass of water, preferably with a meal: ashwagandha holds both water- and fat-soluble compounds.
One ingredient: 500 mg KSM-66® organic ashwagandha root extract per capsule, in a plant-based capsule (hypromellose) with organic rice starch and organic MCT powder as fillers. Nothing else: no leaves, colours or artificial additives. Every batch is lab-tested in Europe. Formulated and produced in the Netherlands.

KSM-66® is the most researched ashwagandha extract in the world. Many other extracts are (partly) made from leaves to cut costs; ours is made only from the root of Withania somnifera to preserve the full spectrum of the root’s compounds, with 5% withanolides and less than 1% withaferin A.
Amounts per serving (1 capsule), as on the label: 500 mg KSM-66® ashwagandha root extract. The label gives no amounts for the capsule and the two fillers, organic rice starch and organic MCT powder.

Withanolides are the group of compounds ashwagandha is standardised on; 5% is the level KSM-66® guarantees in every capsule.
Withaferin A is one specific withanolide that sits mostly in the leaves. A root-only extract keeps it under 1%, which is one reason KSM-66® uses the root alone.
We believe health starts with simple daily habits and our products are made to support that. If in doubt, follow the recommended use on the label, the product page, or feel free to ask us.
Most of our products can be used together. If you’re not sure what works well for you, feel free to reach out to our team. We’re happy to help.
Final production always takes place in the Netherlands, so we stay in full control of quality and safety. We source our ingredients directly from the origin, always from specialists who are best at what they do.
For every ingredient, there’s someone in the world who does it better than anyone else, and that’s who we work with. No middlemen. Only trusted suppliers who meet the strictest European standards.
At Clearly, our mission is simple: to keep searching for the #1, and make it available to you.
Because it’s clearly the inside that counts.
No flashy design or misleading labels, just a transparent pouch, so you can see exactly what’s inside. Too often, we buy things because they look or sound good… but inside? Sugar, fillers, or low-quality ingredients.
At Clearly, we do it Clearly: only #1 ingredients you can trust, and a fully transparent formula.
We use mono-material, one single type of plastic, which makes the pouch 100% recyclable. Unlike most packaging that mixes paper and plastic and can’t be properly recycled.
When it comes to health, the inside matters most. That’s Clearly.
Yes. Every ingredient is lab-tested for heavy metals, microbiology, and other potential contaminants.
We only use clean, traceable raw materials from trusted suppliers who meet the highest European safety standards.
If it’s not safe, tested, and the best, it’s not Clearly. We don’t go for "good enough", we go for #1 quality.
We use our own products daily. And just like you, we only want the best. Because if your health is #1, what you take should be too.
If you’re pregnant or breastfeeding, we recommend checking with your doctor before taking any supplement. During this time, both your health and your baby’s health are clearly #1.

Nos gustan tanto nuestros productos Clearly, el not coffee y Ashwagandha que no podemos viajar sin ellos allá donde vayamos, aunque sea al otro lado del mundo. Aunque tuvimos una experiencia "divertida" con un poco de estrés en el aeropuerto de Doha en el control de seguridad donde nos hicieron sacar los sobres del producto y tuvieron que analizarlos para demostrar que no eran sustancias ilegales. Yo les decía, "I cannot travel without it! IT's cleraly NOT DRUG" Y una vez hechas las comprobaciones, continuamos el viaje sin problema y con nuestros productos favoritos. Me encanta sobre todo aclarar mi mente antes de realizar inmersiones de buceo que requieren mucho nivel y concentración. Y lo de haber dejado el café, es una maravilla! Eramos adictos!!!
Sher hochwertiges Ashwagandha! Ich denke mein Coritsolspiegel von meiner häufigen Laptop Arbeit ist schon deutlich gesunken. Nach bereits wenigen Tagen Einnahme, merke ich einen deutlichen Unterschied. It works! Danke Clearly! 🙏🩵
Gebruik het al best lang en bevalt heel goed. Ik slaap er beter door en voel me relaxter 😁
Ashwagandha KSM-66. Wij thuis nemen het voor betere nachtrust. Verbetert gemoedstoestand en vermindert stress. Er zijn meer goeie ashwaghanda supplementen maar Clearly springt er uit. Zit standaard opgenomen in onze clearly routine. Werkt nog beter met magnesium en zink van clearly
Is gewoon lekker en smaakt naar koffie
