Eggshells are made primarily of calcium carbonate, which means finely powdered eggshell contains calcium. However, eggshell powder should not be presented as a cure for arthritis, joint degeneration, severe joint pain, or difficulty walking.
If someone has severe joint pain, significant stiffness, or difficulty walking, the underlying cause should be evaluated by a qualified healthcare professional rather than treated with a homemade supplement.
For people who choose to prepare eggshell powder, careful sanitation and extremely fine grinding are essential because raw eggshells can carry harmful bacteria and coarse fragments can be irritating.

Step-by-Step Instructions
1. Collect the Eggshells
After using the eggs, rinse the empty shells thoroughly to remove remaining egg residue.
Do not use shells that are visibly dirty, contaminated, moldy, or damaged in a way that makes them difficult to clean.
2. Boil the Eggshells
Place the cleaned eggshells in a saucepan and completely cover them with water.
Bring the water to a boil and continue boiling for approximately 10–15 minutes.
This heating step helps reduce the risk from microorganisms such as Salmonella.
3. Dry the Shells
Remove the shells from the water and allow them to drain.
Spread them in a single layer on a clean baking sheet.
Place them in an oven at approximately 200°F (95°C) for about 10–15 minutes, or until completely dry.
Make sure the shells are thoroughly dried before grinding.
4. Grind Extremely Fine
Once completely dry and cooled, place the shells into a clean coffee grinder or spice grinder suitable for dry ingredients.
Grind them until they become an extremely fine powder.
The finished powder should not contain noticeable sharp or gritty pieces.
If necessary, sift the powder and regrind any larger particles.
5. Store Properly
Transfer the completely dry powder into a clean, dry, airtight container.
Store it in a cool, dry place and keep moisture away from the container.
Label the container clearly so it is not accidentally confused with ordinary cooking ingredients.
How to Use Eggshell Powder
Eggshell powder is essentially a concentrated calcium source rather than a treatment for joint disease.
Because the calcium content can vary depending on shell size and preparation, it is difficult to determine an exact dose of elemental calcium from homemade eggshell powder without laboratory analysis.
For this reason, do not assume that a particular teaspoon measurement provides an exact amount of calcium.
Anyone considering regular use should first consider their total calcium intake from food, supplements, and medications and discuss appropriate amounts with a healthcare professional, particularly if they have kidney problems, a history of kidney stones, or take medications that can interact with calcium.
Why Eggshells Do Not Restore Damaged Joints
Eggshells cannot rebuild severely damaged cartilage or reverse advanced joint degeneration.
Although eggshell membranes contain proteins and other compounds that have been investigated for joint health, eating eggshell powder should not be confused with a proven treatment for advanced arthritis or cartilage damage.
Someone who cannot walk because of severe joint pain or mobility problems needs medical assessment to determine the underlying cause.
Evidence-Based Approaches to Joint Health
Medical Evaluation
Severe joint pain, significant mobility loss, or inability to walk requires professional evaluation.
A doctor may investigate conditions such as osteoarthritis, inflammatory arthritis, injuries, cartilage damage, or other musculoskeletal problems.
Physical Therapy
When appropriate, professionally guided physical therapy can help strengthen muscles surrounding affected joints and improve mobility and function.
The specific exercises should be adapted to the person’s condition and physical abilities.
Healthy Nutrition
A balanced diet containing adequate protein, fruits, vegetables, whole grains, healthy fats, and appropriate sources of calcium and vitamin D can support overall bone and muscle health.
Food sources of calcium include dairy products, fortified plant milks, some fish eaten with their bones, tofu made with calcium, and certain leafy greens.
Clinically Studied Treatments
Depending on the diagnosis, a healthcare professional may recommend medications, physical therapy, weight management when appropriate, assistive devices, injections, or other treatments.
Some supplements, including collagen peptides, glucosamine, or chondroitin, have been studied for joint symptoms, but evidence varies and they should not automatically be considered effective treatments for every person.
Important Safety Precautions
Do not swallow whole or partially crushed eggshell pieces.
Do not use eggshell powder that remains gritty or contains sharp fragments.
Do not consume raw or inadequately cleaned eggshells because of the risk of bacterial contamination.
People with kidney disease, a history of kidney stones, disorders affecting calcium metabolism, or other relevant medical conditions should speak with a healthcare professional before taking concentrated calcium supplements.
Calcium can also interact with certain medications, so anyone taking regular medication should check with a pharmacist or doctor before using eggshell powder routinely.
Common Mistakes to Avoid
Do not skip the boiling step simply because the shells look clean.
Do not grind the shells only briefly and assume that large fragments are safe to swallow.
Do not use homemade eggshell powder as a replacement for prescribed treatment.
Do not take large amounts in an attempt to accelerate recovery from joint pain or arthritis.
Do not assume that more calcium automatically means stronger bones or healthier joints. Excessive calcium intake can cause health problems in some people.
Frequently Asked Questions
Can eggshell powder cure arthritis?
No. There is no basis for claiming that eggshell powder can cure arthritis or reverse advanced joint degeneration.
Can eggshells restore cartilage?
Eggshell powder cannot be relied upon to restore damaged cartilage or reverse structural joint degeneration.
Is eggshell powder a source of calcium?
Yes. Eggshells are primarily composed of calcium carbonate and therefore contain calcium. However, the exact amount available in homemade powder can vary.
Can I eat eggshell powder every day?
Regular supplementation should be approached cautiously because homemade eggshell powder does not provide a precisely measured dose. Discuss routine use with a healthcare professional, especially if you already obtain calcium from your diet or other supplements.
Can eggshell powder help someone who cannot walk?
It should not be used as a treatment for inability to walk. Difficulty walking can have many causes and requires appropriate medical evaluation.
What should I do if joint pain is severe?
Seek medical evaluation, particularly if the pain is severe, suddenly worsens, follows an injury, or prevents normal walking or daily activities.
Final Thoughts
Eggshells naturally contain calcium, but homemade eggshell powder should be viewed only as a potential calcium-containing dietary supplement—not as a cure for arthritis, cartilage damage, severe joint pain, or loss of mobility.
Safe preparation requires thorough cleaning, boiling, complete drying, and extremely fine grinding. Even then, the calcium content of homemade powder cannot be measured precisely without laboratory testing.
For serious joint problems, proper diagnosis, professional guidance, appropriate exercise or physical therapy, and evidence-based treatment are much more important than relying on a homemade remedy.
⚠️ Important Health Warning: Eggshell powder is not a treatment for arthritis, joint degeneration, or inability to walk. Homemade preparations may carry risks if contaminated, improperly ground, or consumed in excessive amounts. If you have severe joint pain, difficulty walking, kidney disease, a history of kidney stones, or take regular medication, consult a qualified healthcare professional before using eggshell powder or any concentrated calcium supplement.
