What Is Certo Used For?
(Leslie Martin)

Certo is a fruit pectin made by Kraft that was initially designed for home jelly- and jam-makers to thicken and gel their creations. However, in recent past, many people have discovered that Certo used for arthritis and joint pain is an effective home remedy, especially when combined with grape or pomegranate juice. In addition, scientists recently discovered that fruit pectin, like that found in Certo, could help inhibit the growth of cancer, as well as provide other health benefits.


Pectin is a naturally occurring complex carbohydrate substance found in most plants, including fruits and vegetables. Certo fruit pectin is derived by extracting pectin from certain fruits and then combining with different preservatives, like sodium benzoate. Pectin itself was discovered and isolated in 1825 by French scientist Henri Braconnot. However, it's been used for thickening jams and jellies for centuries.

Function in Cooking

Certo, when used for cooking purposes, is available in two forms - liquid and powder. Either substance causes a jam, jelly or spread to thicken and increase in viscosity. Typically, Certo fruit pectin works best in jam and jelly making when you prepare your creations in a sterile environment with the proper ratio of acidity (typically citric acid) and sugar. Using Certo, or another fruit pectin product like Sure-Jell, is an efficient and delicious way to preserve seasonal fruits for year-round consumption.

Certo for Arthritis

Although there are no scientific studies to support the claim that Certo mixed with grape juice or pomegranate juice will ease joint pain or arthritis, anecdotal evidence relayed over decades suggests that it is an effective home remedy. The widely recommended dose is to mix 1 tbsp of liquid Certo with 236ml. of grape juice and consume daily. Many have reported relief from excruciating arthritic pain within two weeks of beginning this regimen. However, as with all home remedies, check with your medical provider first to make sure there are no contraindications.

Other Benefits

Despite the lack of scientific explanation as to why Certo helps with joint pain, there are other studies that show how beneficial fruit pectin can be with other health issues. According to a 2008 study, as published in the Federation of American Societies for Experimental Biology, fruit pectin actually stops the growth of cancer cells by binding to them, thus inhibiting metastases. In addition, fruit pectin, like that found in Certo, is regularly suggested for patients who suffer from diarrhoea. Often, when a patient suffers from a flu-like illness, a health care provider recommends the BRAT diet, of which the "A" stands for apples--a fantastic source of fruit pectin.


Unfortunately, despite all of the good Certo can be used for, it also contains a potentially dangerous added substance, sodium benzoate, which is used as a preservative. Studies have shown that sodium benzoate, when combined with citric acid (vitamin C), forms benzene--a known carcinogen. Many grape juices are fortified with vitamin C, so the home remedy for arthritis may come with a caveat. Most fruit pectin products, like Certo or Sure-Jell, contain sodium benzoate, so its best to weigh the pros and cons when treating yourself with these home remedies.
