500 mg of patented KSM-66® Ashwagandha root extract per capsule, standardized to 5% withanolides. A clinically studied adaptogenic herb, rooted in Ayurvedic tradition, supporting your daily wellness routine around stress, sleep, and vitality.
KSM-66 is one of the world's most extensively studied Ashwagandha extracts, referenced in 24+ peer-reviewed clinical papers. Produced using a patented water-based extraction that preserves the full spectrum of the root's natural compounds.
Each capsule delivers 500 mg of pure KSM-66® root extract. 1–2 capsules per day aligns with the daily amounts described in the published literature. 60 capsules per bottle provide a 1–2 month supply.
Withanolides are the signature markers of the Ashwagandha root. Our KSM-66 extract is standardized to exactly 5%, so every capsule delivers a consistent amount — no guesswork, no batch-to-batch variability.
We use plant-based HPMC capsules rather than gelatin. No animal-derived ingredients, dairy, eggs, or honey. Fully suitable for vegetarians and vegans.
Every batch is independently tested for purity, withanolide content, heavy metals (lead, mercury, arsenic, cadmium), pesticide residues, and microbial contamination. Certificates of Analysis are available on request.

Ashwagandha has been used for more than 3,000 years within Ayurvedic tradition as a herb for daily balance. KSM-66® is the Ashwagandha extract most widely reported in the research literature across the following themes. This product is a dietary supplement, not a medicine; individual experiences vary.
KSM-66 has been studied in the context of perceived stress in peer-reviewed papers such as the Indian Journal of Psychological Medicine (Chandrasekhar et al., 2012). A traditional herb for people who value calm and balance in demanding modern routines.
A 2019 paper in Cureus (Langade et al.) explored Ashwagandha root extract in the context of sleep quality. Long associated with evening wind-down rituals in Ayurvedic tradition — a companion to a calmer end-of-day routine.
Research in the Journal of the International Society of Sports Nutrition (Wankhede et al., 2015) has examined Ashwagandha in the context of physical activity. In Ayurveda the root has traditionally been taken by those with active lifestyles.
The Journal of Dietary Supplements (Choudhary et al., 2017) has reported research on Ashwagandha and cognitive function. A traditional companion for days that demand focus, mental clarity, and steady attention.
Individual experiences may vary. This product is not intended to diagnose, treat, cure, or prevent any disease. This is a dietary supplement, not a medicine.
Not all Ashwagandha is the same — extraction methods and plant parts used vary widely, and so does the resulting quality. KSM-66 is a patented root-only, water-based extract developed by Ixoreal Biomed (India). Here is how it compares to Sensoril® and generic Ashwagandha.
| Attribute | KSM-66® (used by Livaya) | Sensoril® | Generic Ashwagandha |
|---|---|---|---|
| Plant part | Root only (100%) | Root + leaf | Root, leaf, or blend |
| Extraction | Patented water-based | Alcohol + water | Varies, often non-standardized |
| Withanolide % | 5% (standardized) | 10%+ (often leaf-derived) | 0.5–5% (inconsistent) |
| Clinical studies | 24+ peer-reviewed papers | A few | Few or unreported |
| Character | Full-spectrum, root-only | High potency, includes leaf compounds | Quality varies by brand |

Take 1–2 capsules per day with water during or after a meal. Many people take it in the morning or early afternoon; others prefer an evening capsule as part of a wind-down routine. Ashwagandha is traditionally taken consistently, so we recommend a continuous routine of at least 4–8 weeks.
Read the full how-to-take guide →Each capsule contains 500 mg of KSM-66® root extract. The recommended daily amount is 1–2 capsules (500–1000 mg); do not exceed this range. Clinical papers typically describe daily amounts of 300–600 mg. We suggest starting with 1 capsule per day before increasing.
See the dosage guide →KSM-66® Ashwagandha is a dietary supplement and is generally well tolerated by most healthy adults. If you are on medication for thyroid, blood sugar, blood pressure, or immunosuppressants, please consult your doctor or pharmacist. Not recommended during pregnancy or breastfeeding without explicit medical supervision. Stop use if you experience any adverse reaction.
Side-effects & cautions →Quality is our non-negotiable foundation. We source directly from Ixoreal Biomed (India), the company that developed and patented the KSM-66® extraction process. Only the root of Withania somnifera is used, harvested from certified farms in Rajasthan and Madhya Pradesh under sustainable agricultural practices. The final product is manufactured in cGMP-certified facilities and every batch is third-party tested for purity, withanolide content, heavy metals, pesticide residues, and microbial contamination. Certificates of Analysis (COA) can be requested at support@livaya.store with a batch number.
Livaya designs its products around an accurate reading of how Withania somnifera is treated under Japan's Ministry of Health, Labour and Welfare guidance and the Food Sanitation Act. Because customers regularly ask whether ashwagandha is legal in Japan, we cite the public source directly so you can verify it for yourself.
Under Japanese regulation, different parts of the Withania somnifera plant are treated differently. The whole plant (zensō, 全草) — which includes leaves, stems and aerial parts — is listed by the Ministry of Health, Labour and Welfare among ingredients classified as "used exclusively as medicinal substances" (専ら医薬品). It is therefore not permitted as an ingredient in foods or dietary supplements sold in Japan.
The root extract, by contrast, sits outside that medicinal-only classification and is currently treated as eligible for use in foods and dietary supplements. The clinical literature on ashwagandha — both in Japan and overseas — overwhelmingly studies standardized root-only extracts.
Livaya's product is built around KSM-66® ashwagandha, which is a 100% root-only standardized extract by design — no leaves, no whole-plant material. We source directly from Ixoreal Biomed in India, and every batch is independently third-party tested for purity, withanolide content, heavy metals, pesticide residues, and microbial contamination.
Why does "root-only" matter beyond regulatory classification? For someone taking a supplement daily, regulatory clarity is itself a quality signal: it indicates a clearly bounded raw material, a verifiable supply chain, and a product that aligns with how Japan currently classifies ingredients suitable for food. We chose KSM-66 specifically so that customers do not have to guess.
「全草は、国内では『専ら医薬品として使用される成分本質（原材料）』に区分され、食品に使用することは認められていません」
Translation: Within Japan, the whole plant is classified as an "essential ingredient used exclusively as a medicinal substance," and is not permitted for use in foods.

“I started taking Ashwagandha during a busy stretch at work as part of my evening wind-down. It has become a small, pleasant part of my daily routine.”
“I searched for 'KSM-66' specifically. The transparency around ingredients and third-party testing is what made the difference for me. The capsules are small and easy to swallow.”
“I value focused mornings during research work, so I added it to my morning habit. Tracked shipping from Hong Kong has been reliable.”
“I have a long-standing interest in Ayurvedic herbs and chose Livaya because support is available in Japanese. Email support was very helpful and thorough.”
Personal impressions. Individual experiences vary. This product is a dietary supplement, not a medicine.
Yes. Ashwagandha has traditionally been taken by people of all genders as part of a daily wellness routine. That said, pregnant and breastfeeding women and anyone on hormone-related medication should consult a doctor before use. If you have questions about use during your menstrual cycle, we recommend speaking with a healthcare professional.
Ashwagandha is traditionally taken consistently, and most people describe it as something that becomes part of their routine over 4–8 weeks. Experiences vary from person to person. This product is a dietary supplement and does not guarantee any specific outcome or timeline.
Multivitamins, probiotics, and similar everyday supplements are rarely a concern. However, if you take medication for thyroid, blood sugar, blood pressure, immunosuppressants, or sedatives, Ashwagandha may interact — please consult your doctor or pharmacist before combining.
We do not recommend Ashwagandha during pregnancy or breastfeeding without explicit medical supervision. Some sources flag cautions for pregnancy. If you are planning a pregnancy, pregnant, or breastfeeding, consult your doctor before taking any supplement including Ashwagandha.
KSM-66® Ashwagandha is generally well tolerated by most healthy adults. Rarely, mild stomach discomfort, drowsiness, or dry mouth have been reported. Discontinue use if you notice any adverse reaction and consult a healthcare professional. If you have existing conditions or take medication, consult your doctor before use.
Ashwagandha is traditionally consumed consistently as part of a daily routine. Missing a day is not a problem, but consistency is what most people find helpful. Some people choose an 8-on / 2-off weekly cycle, but this is a personal preference, not a medical requirement.
KSM-66 uses root only, extracted with a patented water-based process, standardized to 5% withanolides — a full-spectrum extract. Sensoril uses both root and leaf, often with higher withanolide concentrations (10%+), but includes leaf-derived compounds. KSM-66 is backed by more peer-reviewed studies. Livaya chose KSM-66® for its transparency and full-spectrum profile.
This product is a dietary supplement for adults. We do not recommend it for anyone under 20. Minors considering supplements should always speak with a parent or guardian and a doctor. Older adults with existing conditions or medications should also consult a doctor.
