The human body requires good nutrition to renew, repair, and rejuvenate itself on a daily basis. Researchers have found that many people suffer from dietary deficiencies of silica. Several studies have examined silica for its ability to provide the raw materials the body needs to promote healthy cartilage and support for joint protection and maintenance and have found that silica is essential for these processes in addition to providing other health benefits. Silica can be beneficial for everyone – athletes, women, men, convalescents, elderly, etc.

David Wolfe, author of the Beauty Diet, recommends Silica for:

Maintaining joint flexibility

Providing joint support

Protecting cartilage

Osseous development and calcium assimilation

Reducing swelling

Enhancing ligament protection and tissue plasticity

Improving the elasticity of the skin, as well as the strength and luster of the hair and nails

Supporting collagen production for healthy, youthful looking skin

Decreasing demineralization


Joint Health – Since collagen is vital to healthy joints, ligaments, and cartilage, silica is important too. It lends strength and elasticity to collagen so joints are more flexible, heal quicker, and can snap back from the daily wear and tear our bodies undergo with all our bending, twisting, and stretching. Many people use silica to help ease joint pain and arthritis symptoms.


Bone Health – There are many studies that show that the presence of silica helps the body use calcium. As we get older our silica levels decline and our bones weaken. Mice fed low silicon diets also had lower bone density. There is plenty of evidence that silica is vital to bone health and preventing fractures as we get older. Teeth and gums get a boost from silica too.


Heart Health – Silica is more prevalent in healthy hearts than diseased hearts. Since silica strengthens muscle tissue, this shouldn’t be too surprising. It also aids the body in calcification of bones and thus prevents the calcification of other tissues. There is some evidence that silica may help offset the calcification of arterial plaque. It may also play a role in the electrochemical transmissions of the nervous system.


Digestive Disorders – Silica is important in strong stomach and digestive tract muscles and tissues. Silica assists in rebuilding and fortifying these tissues after they have been damaged by poor diet, parasites, or other injury. It also helps flush out bad bacteria, toxins and parasites.


Immune System – Since silica is a vital part of healthy skin and digestive tissue, it is also important in preventing illness and infection. The skin and our digestive system are the first lines of defense we have against pathogens.


Healing – As a part of collagen, silica can speed healing of burns, wounds, and scar tissue. Detoxification – Silica is very good at removing waste material, toxins, and heavy metals from the body. This makes silica a good addition to any detox program to deeply cleanse your cells.


Detoxification – There is some evidence that aluminum buildup contributes to Alzheimer’s, and a recent study showed that silica may play a part in the removal of aluminum. This wasn’t the best study and plenty more needs to be done, but it is still encouraging that silica may help rid ourselves of this pesky metal that is far too prevalent in our environment, beauty products, and foods.


Our highly processed food diet tends to be severely lacking in silica. We remove it from most of the foods that contain it and avoid many of the fresh fruits and vegetables that are the richest in it. It is best to get your silica from natural sources. Whole foods that are rich in fiber are also rich in silica as plants use this mineral for strength and flexibility as well. Cucumber, celery, asparagus, sweet potatoes, leafy greens, beans, leeks, and even strawberries are great sources for silica. –
