Magnesium Stearate: A Potential Health Hazard?

Did you know that Magnesium Stearate is currently under review in relation to digestive enzymes? It’s true. Ongoing research is currently looking into its impact on nutrient absorption.*

A common excipient in many nootropics, this additive is more than just a passive ingredient.

Magnesium Stearate is typically listed in the fine print under the "Inactive" or "Other" section of a nootropic label. That's likely why many think Magnesium Stearate is just a simple additive that doesn't affect the body.*

However, that's not entirely true. In fact, it's an active participant that may interfere with your body's natural processes. For example, ongoing research suggests that Magnesium Stearate may negatively impact digestive enzymes.*^1,2

And since nutrient absorption is so important (even more so if we talk about nootropics), anything that may hinder it can potentially lead to deficiencies and health challenges.*

Hold on. What is Magnesium Stearate, and what is it used for?

Magnesium Stearate is a white, powdery variety of salt resulting from a blend of stearic acid, a naturally occurring fatty acid, and Magnesium.

Brands typically add it in nootropics (and other dietary supplements), pharmaceuticals, and cosmetics. In fact, you likely use at least one product that contains Magnesium Stearate right now.

But Magnesium Stearate serves a very particular purpose when it comes to nootropics. It acts as a flow agent (or lubricant), preventing the individual ingredients from sticking to each other and the equipment used in the production process.

This way, the production process runs smoothly and the dosage of the active nutrients remains consistent in each capsule or tablet.

It sounds like it’s a good thing, right? Are we overlooking potential risks?

Magnesium Stearate can be derived from various sources, including cottonseed or palm oil. However, these sources can sometimes be genetically modified (GMOs) or treated with pesticides.³ This can raise some valid concerns. Like the risk of contamination with potentially harmful substances. These chemicals can leave residues that may end up in the final product, posing health risks to consumers.*

Magnesium Stearate has no nutritional value.*

It's a common misconception that Magnesium Stearate is a primary source of nutritional Magnesium and may offer some health benefits. This is not true. It's important to differentiate between different Magnesium forms. In reality, this additive is devoid of nutritional value. It's nothing more than a filler.*⁴

As mentioned before, its primary function is to aid in the manufacturing process. It's there to ensure that the active ingredients in a tablet or capsule don't adhere to the machinery during production. A lubricant, if you will.

At HCF® we value Magnesium Stearate-free nootropics.

Clean-label nootropics are not just a passing trend. They are a fundamental need. Nootropics that prioritize the health of your entire brain network (head, heart, and gut) over manufacturing convenience. Advanced nootropics that are transparent about what's inside and how each nutrient may benefit all three Intelligence Centers and overall well-being.
