Nano particles are too small to be blocked by the biological methods, like membrane walls, so are reaching parts of the body where its now being learnt that its causing trouble in the body. https://jnanobiotechnology.biomedcentral.com/articles/10.1186/s12951-021-00916-2#:~:text=Despite%20these%20nanoparticles%20are%20generally,10%2C11%2C12%5D https://jnanobiotechnology.biomedcentral.com/articles/10.118.... The European Food Safety Agency wants to ban silicon dioxide in food because there is a risk through lack of quality control in food products that nano particles exist in food products and becomes toxic to the body. https://www.efsa.europa.eu/en/efsajournal/pub/5088 https://www.efsa.europa.eu/en/efsajournal/pub/5088 You'll find silicon dioxide is used in many supplements as an anti caking agent and in some cases these are an ingredient found in vitamin and mineral supplement capsules, potentially negating any health benefits and in fact making health conditions worse or introducing new more dangerous health conditions, creating the situation that doing nothing would have been better.
