Navayas Lauh and Saptamrit Lauha are both classical iron preparations, yet their ingredient profiles and traditional positioning differ enough to affect bulk.
Both Navayas Lauh and Saptamrit Lauha are classical multi-herb iron preparations recorded in the Ayurvedic Formulary of India. Their ingredient profiles and traditional contexts differ enough that brand owners, distributors and Ayurvedic clinics sourcing in bulk need to understand those differences before committing to a formulation or a supplier.
Navayas Lauh is referenced in the Sharangdhar Samhita and the Bhaishajya Ratnavali, two of the most authoritative classical Ayurvedic texts. The prefix "nava" means nine, reflecting the nine principal ingredients arranged around Lauha Bhasma as the central mineral. The formulation is listed in the Ayurvedic Formulary of India, which gives it a defined composition that licensed manufacturers must follow precisely.
Saptamrit Lauha appears in the Bhaishajya Ratnavali and other classical references. "Sapta" means seven, pointing to its seven principal components. The formulation has a distinct traditional positioning in Ayurvedic literature, associated with specific haematological and ocular contexts as classified in the classical system. Like Navayas Lauh, it is listed in the Ayurvedic Formulary of India and regulated under the Drugs and Cosmetics Act.
Both formulations belong to the Lauha-Mandoor category, the segment of classical Ayurvedic manufacturing centred on iron-based mineral preparations. Manufacturers producing either formulation require an AYUSH manufacturing licence covering this specific product category.
The table below summarises the key compositional differences as recorded in classical texts and the Ayurvedic Formulary of India.
| Feature | Navayas Lauh | Saptamrit Lauha |
|---|---|---|
| Classical source | Sharangdhar Samhita, Bhaishajya Ratnavali | Bhaishajya Ratnavali |
| Principal mineral | Lauha Bhasma | Lauha Bhasma |
| Number of key ingredients | Nine | Seven |
| Distinguishing herbals | Trikatu, Vidanga, Chitraka, Triphala | Triphala, Yashtimadhu |
| Traditional context | Haematological and digestive | Ocular and haematological |
| Commercial form | Tablet or powder | Tablet or powder |
The most significant distinction from a practitioner's perspective is the herbal profile. Navayas Lauh combines Triphala with pungent digestive herbs including Trikatu (ginger, black pepper and long pepper) and the anthelmintic herb Vidanga, alongside Chitraka. Saptamrit Lauha pairs Lauha Bhasma with Triphala and Yashtimadhu (liquorice root), a herb that occupies a different functional space in classical Ayurvedic formulation logic.
Practitioners who specify one formulation by name will not accept the other as a substitute. This has a direct implication for brand owners: procurement must be precise, and a supplier who cannot reliably maintain the exact AFI composition is not a viable partner for either product.
Lauha Bhasma is the critical ingredient in both formulations and the most technically demanding to produce. Its manufacture involves shodhana (purification of raw iron through a series of quenching cycles in herbal liquids) followed by marana (a multi-cycle incineration process in a sealed earthen pot). The Ayurvedic Pharmacopoeia of India specifies test parameters for the finished bhasma.
A buyer sourcing either formulation in bulk should expect the following quality checks to have been performed on each Lauha Bhasma lot. The classical Rekhapurnata test verifies that the bhasma is fine enough to fill the lines of a fingertip when rubbed. The Varitara test checks that the bhasma floats on water surface tension rather than sinking. These indicate that the incineration and trituration cycles were completed correctly.
Modern instrumental tests required under Schedule T GMP include total iron content by atomic absorption spectroscopy or ICP-OES, loss on ignition, heavy metal limits (lead, arsenic, mercury and cadmium must each fall within pharmacopoeial limits), and microbial limits covering total bacterial count and absence of specified pathogens. A GMP-certified manufacturer should provide a certificate of analysis covering all of these parameters for each batch of Lauha Bhasma used in production.
For a brand building a comprehensive classical Ayurvedic portfolio, stocking both formulations is commercially sensible. Navayas Lauh has broader traditional usage across the practitioner channel in northern and central India. Saptamrit Lauha is more specifically sought by practitioners and institutional buyers focusing on the ocular and haematological conditions associated with it in classical Ayurvedic literature.
Regional preference also plays a role. Distributors serving markets in Uttar Pradesh, Bihar and Madhya Pradesh typically report demand for both formulations, with the exact mix depending on the practitioner community and institutional buyer base in each district. For a brand owner contracting a manufacturer for the first time, starting with the formulation that your current practitioners already specify by name is the most efficient path.
Consolidating both products under a single manufacturer who carries the full Lauha-Mandoor range reduces logistics complexity and simplifies quality documentation across your catalogue. It also allows you to expand gradually without changing your supply chain structure.
A structured sourcing checklist should cover the following areas before any purchase order is raised.
Formulation compliance: confirm that the manufacturer follows the Ayurvedic Formulary of India specification exactly, not an abbreviated or modified version. Request the product specification document showing the full ingredient list with quantities per unit.
AYUSH licence and GMP certificate verification: check that the manufacturing licence specifically covers the Lauha-Mandoor category. Ask for the GMP certificate number, which can be cross-referenced with the state licensing authority.
Raw material traceability: each herbal and mineral ingredient should have a supplier record, inward lot number and incoming quality control report on file. This is especially important for Lauha Bhasma, which must be traceable back to its specific production batch, and for Yashtimadhu in Saptamrit Lauha, which varies in quality by sourcing region.
Certificate of analysis with every consignment: this document should travel with each bulk shipment, listing the test results for the specific batch supplied, covering identity, assay, heavy metals and microbial limits.
Sample before commitment: a manufacturer confident in their product will offer samples ahead of a bulk order. Testing those samples through an independent laboratory is standard practice for buyers operating a formal quality assurance programme.

Navayas Lauh is a nine-ingredient formulation that combines Lauha Bhasma with Trikatu, Triphala, Vidanga and Chitraka, and is traditionally positioned in haematological and digestive contexts. Saptamrit Lauha uses seven ingredients centred on Lauha Bhasma, Triphala and Yashtimadhu, with a classical association with ocular and haematological conditions. The herbal companions are what distinguish them most clearly.
No. These are distinct classical formulations with different compositions and different traditional positioning. Practitioners and institutional buyers who specify one formulation will not accept the other as a substitute. A brand owner should source whichever formulation their channel specifies and verify that the supplier follows the Ayurvedic Formulary of India composition exactly.
Request a certificate of analysis showing total iron content by AAS or ICP-OES, loss on ignition, heavy metal limits for lead, arsenic, mercury and cadmium, microbial limits, and classical identity tests including Rekhapurnata and Varitara. Each of these should be reported per batch and should be specific to the lot being supplied, not a generic product report.
Navayas Lauh is referenced in the Sharangdhar Samhita and the Bhaishajya Ratnavali. Saptamrit Lauha appears primarily in the Bhaishajya Ratnavali. Both formulations are also listed in the Ayurvedic Formulary of India, which is the regulatory reference that GMP-licensed manufacturers in India are required to follow for composition and preparation method.
