What is magnesium stearate, what is it made from, and is it dangerous?

Answer: Magnesium stearate is found in many supplements because, during supplement manufacture, it makes it easier to work with certain ingredients, making them flow more evenly and preventing them, as well as tablets, from sticking to machines during production. It is created from reacting stearate (from animal fats — often pig — or plant-based sources such as palm oil, coconut oil, or vegetable oil) with magnesium. A very small amount is used in supplements, and it typically comprises less than 1% of a total formulation — less than 20 mg. If it's in a product, you'll see it included in the "Other Ingredients" section of supplement labels. Concerns have been raised that magnesium stearate can have negative effects, such as raising cholesterol levels, suppressing the immune system, creating biofilms in the body, and causing allergic reactions.
As discussed below, there is insufficient scientific evidence to justify these concerns. 1/18/24, 12:40 PM Magnesium Stearate in Supplements - Is it Safe? - ConsumerLab.com https://www.consumerlab.com/answers/i... 2/2 Member: 537003 | Printed: 01/18/2024 12:40 p.m.
Increasing cholesterol levels: Concern has been raised about the stearic acid in magnesium stearate raising cholesterol levels, as stearic acid is a saturated fat. This should not be a concern because even normal dietary intake of stearic acid has been shown to have no significant effect on total cholesterol, low-density lipoprotein (LDL) or high-density lipoprotein (HDL) cholesterol levels (Yu, Am J Clin Nutr 1995). In addition, the amount of stearic acid from magnesium stearate in supplements is very small. According to USDA nutrition surveys, the average American adult consumes between 5,900 to 8,800 milligrams of stearic acid each day, typically from food sources like beef, poultry, cocoa butter, milk and cheese. A single chocolate bar contains about 5,000 milligrams of stearic acid. Meanwhile, the amount of stearic acid in the magnesium stearate in a dietary supplement is generally less than 20 milligrams.
Immune suppression: Some websites claim that magnesium stearate suppresses the immune system. This claim seems to be based on on laboratory studies of immune cells from mice showing that that large amounts of stearic acid damaged cell membranes of T-lymphocytes (Tebbey, Immunology 1990). However, these laboratory conditions do not represent what happens inside your body when you ingest normal amounts of stearic acid, let alone even smaller amounts of magnesium stearate. It is highly unlikely the small amount of magnesium stearate in supplements cause immune suppression, and such an effect has not been reported. Biofilm production: One popular website claims that magnesium stearate can promote the growth of bacterial colonies in the gastrointestinal tract and create a "biofilm" preventing the absorption of nutrients. However, there does not seem to be clinical evidence behind this. In fact, a laboratory study found stearic acid to inhibit the formation of biofilms (Soni, J Food Prot 2008).
