Each herbal ingredient of Liv.52 is been analyzed as per the standards set by Pharmacopoeia. The battery of non-clinical toxicological studies (acute, subacute, chronic, genotoxicity, developmental, and reproductive toxicity studies) have further reinforced the safety of Liv.52, with a wide margin. We ensure consistent quality in every batch (as per WHO standards for herbal medicine). Himalaya's manufacturing facility is GMP certified and audited at regular intervals by several regulatory agencies around the world, wherever our products are marketed. Also, Himalaya Wellness Company's advanced Research and Development (R&D) Center is certified for Good Laboratory Practices (GLP) for following international OECD guidelines.

With reference to heavy metals, considering some trace levels of heavy metals occurring naturally in botanical/ plants/ food ingredients, many regulatory agencies have defined the permissible limits for heavy metal contaminants in herbal medicines after considering the epidemiological aspects of such contaminants. In this direction, both WHO and AYUSH have defined the limits of heavy metals (NMT 10 ppm of lead) in Ayurvedic Medicines. We, at Himalaya Wellness Company, follow these guidelines for all our medicinal products and ensure that our products comply with these regulations. Apart from these, we align with the quality guidelines published by major regulatory agencies like USFDA (12.5mcg/day of lead), Health Canada (10 mcg/day of lead), HSA Singapore (10 ppm of lead), etc., to ensure highest quality of the product. The table below indicates the permitted levels of heavy metals by different international agencies, and Liv.52 complies with all the below mentioned standards.
