Is magnesium stearate toxic?

[EugeneTheSage]

Recently I've received a post package from my mum and there were supplements. The package was cheap so I suspected these were low quality supplements. They contained magnesium stearate, silicon dioxide.

I remember Leo listing in his nootropic video magnesium stearate and silicon dioxide among substances to avoid. I haven't found much concerning info about these 2 on the internet though

Here is the source about magnesium stearate https://www.ncbi.nlm.nih.gov/pmc/articles/PMC5655391/#!po=52.6786

Here's some quote:

Upon ingestion, magnesium stearate dissolves into its component ions, magnesium and stearic and palmitic acids. Therefore, the safety assessment should be based on its constituent cations and anions. Fatty acids are normal constituents of coconut oil, butter and other edible oils and have not been considered to pose a toxicological risk [4], [31]. As such, it was concluded that stearic and palmitic acids used as flavouring agents do not present a safety concern [32]. This position has been supported by results of recent studies demonstrating a lack of genotoxicity and toxicity of some fatty acids containing stearic and palmitic acids

And there is silicon dioxide study. Definitely cautious

What do you guys know about these 2 substances?
