Products & Grades
What purity grades of stevia extract do you manufacture?
Two grades: Purified Stevia Leaf Extract at 60–70% steviol glycosides (light brown powder, one-stage purification) and Highly Purified Stevia Extract at 95–98% steviol glycosides (near-white powder, three-stage purification). Both are manufactured from a single, non-GMO Stevia rebaudiana variety grown on our own Hyderabad farm.
Which grade is right for my formulation?
The 70% grade suits Ayurvedic and herbal formulations — churnas, kadhas, and herbal teas — where the authentic leaf character is welcome and cost matters. The 95–98% grade is built for nutraceutical, pharmaceutical, and food & beverage applications that demand a near-white powder, high solubility, and a clean sweetness profile with minimal bitterness. If you are unsure, share your application with us and we will recommend a grade and send samples.
How sweet is stevia compared to sugar?
Steviol glycosides are commonly 200–300 times sweeter than sucrose, so a very small dose replaces a large amount of sugar. Typical usage: a pinch (about 0.1–0.2 g) per cup of herbal tea, or 0.1–0.5 g in an Ayurvedic formulation as directed.
What pack sizes do you offer?
Standard packs of 50 g, 100 g, 250 g, 500 g, and 1 kg. Bulk and custom packaging for commercial volumes are available on request.
Quality & Compliance
Do you provide a Certificate of Analysis?
Yes — every batch ships with a Certificate of Analysis covering appearance, moisture, steviol glycoside assay (HPLC-verified), heavy metals (lead, cadmium, arsenic, mercury), and microbiology (total aerobic count, E. coli, Salmonella). Full batch traceability is maintained from field to finished powder.
Is your stevia approved in India?
Yes. Natural Harmony holds FSSAI License 13626999000270, and steviol glycosides are a permitted food additive in India under INS 960. Our 60–70% extract is additionally classified as an Ayurvedic Proprietary Medicine (APM).
Is stevia safe to consume?
High-purity steviol glycosides are recognised as safe by major global authorities: GRAS status with the US FDA, approval by EFSA in Europe, and a WHO/JECFA acceptable daily intake of 4 mg per kg of body weight per day. See our Science & Quality page for the full regulatory table and clinical research summary.
What is the shelf life, and how should it be stored?
Two years when sealed and stored below 25°C. Keep in a cool, dry place away from moisture and direct sunlight, and seal tightly after use.
Sourcing & Supply
Can I get samples before committing to an order?
Yes — we encourage it. We provide evaluation samples along with specifications, a batch Certificate of Analysis, and our white papers so your R&D team can validate the ingredient in your own formulation before any commercial commitment. Samples for Ayurvedic practitioners are also available.
What are your minimum order quantities and prices?
Pricing and MOQ vary by grade, volume, and packaging. Share your application and required quantity through our contact form and we will respond with a formal quotation within 1–2 business days.
Do you offer bulk B2B supply or white-label manufacturing?
Yes — bulk B2B supply and white-label options are available. Our capacity roadmap scales from 3 tonnes to 24 tonnes over the next four years, with the same verified purity profile batch after batch. Contact us to discuss volumes, specifications, and timelines.
Where is your stevia grown and manufactured?
Everything happens in and around Hyderabad, Telangana. We cultivate a single proprietary non-GMO variety on our own farm — propagated from saplings to preserve genetic integrity — and purify it using our proprietary green extraction technology, with no harsh chemical solvents at any stage.
