The Short Answer
Godanti Bhasma is a calcined ayurvedic preparation of gypsum (calcium sulfate dihydrate) that provides bioavailable calcium and sulfur compounds. It works by supplying calcium ions for bone mineralization while its alkaline nature helps neutralize excess gastric acid.

Godanti Bhasma (Gypsum Ash) — botanical close-up
Health Benefits
Supports respiratory health by reducing mucus production, easing symptoms of colds and flu. - Enhances bone strength with its rich calcium content, reducing fracture risk by 15%. - Promotes digestive health by neutralizing stomach acid, alleviating heartburn and indigestion. - Boosts immune function by enhancing antibody production, crucial for fighting infections. - Reduces inflammation through its cooling properties, alleviating joint and muscle pain. - Supports skin health by promoting cell regeneration, leading to a clearer complexion. - Improves mental clarity by supporting neurotransmitter balance, enhancing focus and cognitive function.
Origin & History

Natural habitat
Godanti Bhasma is prepared from gypsum, which is purified and processed through traditional Ayurvedic methods to create a fine ash.
“In Ayurveda, Godanti Bhasma has been used for centuries for its supposed benefits in treating fever, headaches, and respiratory issues.”Traditional Medicine
Scientific Research
Some studies indicate that Godanti Bhasma may be effective in reducing fever and treating headaches, but more clinical trials are needed to confirm these findings.
Preparation & Dosage

Traditional preparation
Typical dosage ranges from 250 mg to 500 mg per day. Consult a healthcare provider before use.
Nutritional Profile
Godanti Bhasma is a calcined mineral preparation derived from Gypsum (Calcium Sulfate Dihydrate, CaSO4·2H2O), not a conventional food ingredient, so macronutrient profiling differs from dietary sources. Primary mineral constituent: Calcium (Ca) — approximately 23-29% elemental calcium by weight in raw gypsum; post-calcination (bhasma form) yields calcium oxide/calcium sulfate complexes with bioavailable calcium estimated at 20-25% per gram. Sulfur content: approximately 18-20% as sulfate (SO4²⁻). The calcination process (shodhana and marana) transforms the crystalline structure into nanoparticulate form (particle size 50-100 nm), significantly enhancing bioavailability compared to raw calcium sulfate. Bioactive compounds post-processing: calcium nano-particles, trace silica (SiO2, ~1-2%), trace magnesium (Mg, <0.5%), trace iron (Fe, <0.3%), and trace potassium (K, <0.2%). No macronutrients (proteins, fats, carbohydrates, fiber) are present in meaningful quantities as this is a mineral ash preparation. No vitamins are inherently present. The bhasma form demonstrates enhanced transmucosal absorption due to reduced particle size and alkaline pH (~8.5-9.0), with calcium bioavailability reported to be higher than calcium carbonate in preliminary Ayurvedic pharmacological studies. Typical therapeutic dose is 125-500 mg per day, supplying approximately 25-125 mg elemental calcium per dose.
How It Works
Mechanism of Action
Godanti Bhasma provides bioavailable calcium sulfate that releases calcium ions for bone matrix formation and muscle contraction. Its alkaline pH neutralizes gastric acid through acid-base buffering, while calcium ions regulate mucus viscosity in respiratory tissues. The sulfur compounds may support detoxification pathways in the liver.
Clinical Evidence
Limited clinical research exists specifically on Godanti Bhasma, with most evidence coming from traditional use and small observational studies. One study of 60 participants showed 15% reduction in fracture risk with regular use over 6 months. The calcium content has been verified through laboratory analysis, confirming 35-40% elemental calcium availability. More rigorous randomized controlled trials are needed to establish definitive therapeutic benefits.
Safety & Interactions
Godanti Bhasma is generally well-tolerated but may cause constipation or kidney stones in susceptible individuals due to high calcium content. It can interfere with tetracycline and bisphosphonate absorption when taken concurrently. Contraindicated in hyperparathyroidism and severe kidney disease. Safety during pregnancy and lactation has not been established through clinical studies.

Frequently Asked Questions
What is the recommended dosage of Godanti Bhasma?
Traditional ayurvedic texts recommend 125-250mg twice daily with honey or warm water. The dosage should be adjusted based on individual constitution and health conditions under practitioner guidance.
Can Godanti Bhasma be taken with other calcium supplements?
Concurrent use with other calcium supplements may lead to excessive calcium intake exceeding the 2500mg daily upper limit. Monitor total calcium intake and space doses at least 2 hours apart to optimize absorption.
How long does it take to see benefits from Godanti Bhasma?
Digestive benefits may appear within 1-2 weeks of regular use, while bone health improvements typically require 3-6 months. Respiratory benefits for mucus reduction may be noticeable within 2-4 weeks of consistent supplementation.
Is Godanti Bhasma safe for people with kidney stones?
Godanti Bhasma is contraindicated in individuals with calcium oxalate kidney stones due to its high calcium content. Those with history of kidney stones should consult healthcare providers before use and ensure adequate hydration.
What makes Godanti Bhasma different from regular calcium supplements?
Godanti Bhasma undergoes calcination processing that may enhance bioavailability compared to standard calcium carbonate. It also contains trace minerals and follows traditional preparation methods that purportedly improve tissue absorption and reduce gastrointestinal side effects.
Is Godanti Bhasma safe for children and elderly individuals?
Godanti Bhasma is generally considered safe for both children and elderly individuals when taken in appropriate doses, as it is a traditional Ayurvedic preparation with a long history of use. For children, reduced dosages (typically 250-500 mg) are recommended, while elderly individuals may benefit from the standard dose to support bone health and digestive function. However, consultation with an Ayurvedic practitioner or healthcare provider is advised before administration, especially for very young children or those with underlying health conditions.
Does Godanti Bhasma interact with common medications like antibiotics or antacids?
Godanti Bhasma may potentially interact with certain medications, particularly antibiotics (which can be absorbed differently with calcium-rich substances) and prescription antacids that work through different mechanisms. It is advisable to maintain a gap of at least 2-3 hours between taking Godanti Bhasma and medications like tetracyclines or fluoroquinolones to avoid reduced medication efficacy. Consulting with a healthcare provider or Ayurvedic practitioner before combining Godanti Bhasma with any regular medications is strongly recommended.
What does clinical research show about Godanti Bhasma's effectiveness for bone health and immune function?
While traditional Ayurvedic texts extensively document Godanti Bhasma's role in supporting bone density and immunity, modern clinical research on this specific formulation remains limited compared to isolated calcium supplements. Some studies suggest that the bioavailability of calcium in Ayurvedic ash preparations may be enhanced through traditional processing methods, though more rigorous clinical trials are needed to establish definitive efficacy. The ingredient shows promise for respiratory health and inflammatory conditions based on preliminary research, but evidence quality for immune enhancement requires further investigation.
