40+ Amazing Diatomaceous Earth Uses For Health, Home And Garden by Joan Clark

Diatomaceous earth is made up of fossils of tiny algae-like organisms called diatoms. It is a soft white powder made of 80 to 90 percent silica. Unlike many silica sources, the silica found in diatomaceous earth is highly absorable by the human body. Its high absorption rate makes it an excellent supplement for health benefits.

Many people are not aware of the many uses and benefits of diatomaceous earth. Not only is it a health-promoting supplement, but it is also useful for cleaning and pest control. We have put together this guide to try to pass on more information about how to use diatomaceous earth.


Use Only Food Grade Diatomaceous Earth for Human or Pet Consumption. If you choose to take diatomaceous earth for health benefits, you must use food-grade diatomaceous earth. Industrial grade or pool grade diatomaceous earth contains impurities that may not be healthy for the body. Many sources of industrial grade diatomaceous earth has also been heat-treated, and it no longer has the properties that provide the health benefit

Diatomaceous Earth Uses and Benefits for Health

1. Take Diatomaceous Earth for Detoxification

Diatomaceous earth carries a negative charge, so it attracts positively charged toxins and heavy metals from the body and flushes them out. A study in the American Journal of Clinical Nutrition found that the silica diatomaceous earth helps eliminate aluminum and other heavy metals from the body. (..)

How to Use Diatomaceous Earth for Detoxing and to Kill Parasites

7. Improve Bone Density

Calcium and Vitamin D are usually given to improve bone growth, but most people don’t realize that the body cannot absorb calcium without the addition of silica.

Taking silica in the form of diatomaceous earth helps the body absorb and use the calcium, magnesium, and phosphorus to form healthy bones. It speeds the healing of fractures and helps prevent Osteoporosis.

8. Helps Prevent Alzheimer’s Disease

Current research into Alzheimer’s disease links it to the presence of aluminum in the brain. Most of the aluminum comes from drinking water.

Adding silica, in the form of diatomaceous earth, to the drinking water or the diet helped prevent the aluminum from being absorbed. Research shows that it lowered aluminum concentrations in the brain, bones, liver, spleen, and kidneys.

9. Diatomaceous Earth Improves Heart Health

Silica from diatomaceous earth fortifies the blood vessels and strengthens heart tissue. It also lowers cholesterol, removes plaque, and keeps the arteries and veins elastic. Silica also plays a role in regulating blood pressure.

10. Diatomaceous Earth Reduces Cholesterol

Unhealthy fats in the digestive tract are absorbed and trapped by diatomaceous earth and removed from the body. By reducing the unhealthy fats, diatomaceous earth effectively reduces the bad cholesterol level in the body.

11. Use Diatomaceous Earth as an Exfoliant

How to Use Diatomaceous Earth as an Exfoliant

  • Mix to form a thick paste:

  • Allow it to dry, if desired, or rinse it off immediately. Do not leave on too long; it can dry the skin.

Diatomaceous earth is mildly abrasive and makes an excellent exfoliant alone or mixed into your favorite cleanser.

When properly used, it gently removes dead skin cells and cleans the skin, soaking up excess oils. It leaves the skin soft, supple, and glowing.

12. Diatomaceous Earth Prevents Wrinkles and Signs of Premature Aging

Silica is an excellent support mineral for skin and connective tissues. Collagen is mostly made of silica and is responsible for the elasticity of the skin and its ability to repair itself. Degrading of connective tissue and a lack of collagen causes wrinkles and sagging skin. Regular diatomaceous earth supplementation replaces the silica needed to produce collagen and support the connective tissues.

13. Diatomaceous Earth Supports Healthy Hair

Our hair is rich in silica and requires it to grow and shine. A good supplementation plan using diatomaceous earth will stimulate hair growth and help prevent hair loss. When silica is plentiful in the body, hair grows in healthy and shiny.

14. Silica Supports the Immune System

Diatomaceous earth supports the immune system and its ability to produce the antibodies we need to fight disease. Silica found in diatomaceous earth is important to many of the body’s systems, including the immune system. It also removes toxins and kills off parasites, allowing the immune system to function better.

15. Diatomaceous Earth for Diabetes

Safety Concerns of Diatomaceous Earth

Food grade diatomaceous earth is considered safe, and no negative side effects are known. It has been approved by the FDA as a supplement and can be used by anyone, but you should consult with your doctor before taking diatomaceous earth. It can interfere with some medications, eliminating them entirely or making them less effective. However, there are a few health concerns.

First, avoid getting diatomaceous earth in your eyes. It is extremely drying and will irritate your eyes. If you do get DE dust in your eyes, wash it out with a continuous stream of water and do not rub your eyes.

Second, diatomaceous earth dust is very fine and can be irritating to lung tissue if you breathe it in. It can accumulate in the lungs and lymph nodes if you are repeatedly exposed. Avoid breathing the dust and wear a face mask when using it in ways that create a large amount of dust.

It is always possible that you could have a negative reaction to any supplement. While a reaction is highly unlikely, you should begin with a small dose, approximately 1/2 teaspoon or less and gradually increase your dosage. This way, you will limit any reactions and catch them before they can become intense. Your body will gradually get used to the increased doses.

Is Diatomaceous Earth Safe for Babies?

No data suggests that diatomaceous earth is harmful to babies in any way. However, we recommend that you consult with a doctor before giving any supplement to a baby, including diatomaceous earth.

Is Diatomaceous Earth Safe for the Environment?

Silica, the major component of diatomaceous earth is the second most abundant element in soil. It is a natural and common component of rock, sand, and clay. Diatomaceous earth is a completely natural compound that has no detrimental effects on the environment. Using diatomaceous earth instead of harmful pesticides is beneficial to the environment.

Diatomaceous earth is non-toxic for fish, birds, and other wildlife and has no known harmful effects. Scientists believe that it is completely safe for wildlife. (..)

What are the Side Effects of Diatomaceous Earth?

Always make sure you are taking food grade diatomaceous earth. It is a safe and beneficial supplement for most people, with the following exceptions:

When you begin taking diatomaceous earth, detoxification of the body begins, and parasites are attacked. This can cause a flood of toxins and dying parasites leaving the body in the first few days. Many people will experience flu-like symptoms during this time. This is evidence that the DE is working and you will feel better soon. Stay on schedule.

As with any supplements, if you are pregnant or nursing, you should consult your doctor before taking diatomaceous earth.

Also, people who are taking medications should consult their doctor before taking diatomaceous earth. It can absorb medicines and flush them out of the body – an unwanted side effect.

Since diatomaceous earth naturally lowers blood pressure, you should carefully monitor your blood pressure while taking diatomaceous earth, especially if you have naturally low blood pressure or if you are on blood pressure medications.

What is the Difference Between Diatomaceous Earth and Fullers Earth?

Fuller’s earth is a natural clay that has many benefits similar to diatomaceous earth. It is absorbent and a deodorizer. It is found in many cosmetics and beauty products. Despite their similarities, diatomaceous earth is an entirely different compound.
