It is manufactured in FSSAI-licensed, GMP-certified (audited by TÜV India) and FSSC 22000-certified facilities, and every batch is third-party tested at an NABL-accredited lab.

Can I take it with my medicines?

Speak to your doctor or pharmacist first if you take any medicine, especially sedatives or medicines for blood pressure. This product is a food supplement, not a medicine, and should not replace anything your doctor has prescribed.

Is it vegetarian?

Yes. The label says it is suitable for vegetarians, and the capsule shell is plant-based HPMC (hydroxypropyl methylcellulose). The label also says it is not manufactured with milk, soy, egg, fish or crustacean, and is produced in a facility that processes other ingredients containing these allergens.

Who should not take it without advice?

The pack says it is for adults, so it is not meant for children. If you are pregnant or breastfeeding, prone to a food allergy or have a medical condition, consult your healthcare professional before use. If you notice any adverse effect, stop using it and speak to your doctor. This product is not intended to diagnose, treat, cure or prevent any disease.
