Total aluminium exposure through food, consumer products and soil is well below the health-based guidance value. This is the maximum daily intake that will not lead to any adverse effects. RIVM National Institute for Public Health and the Environment concluded this by reviewing research on behalf of the Ministry of Health, Welfare, and Sports.
Low exposure to aluminium through personal care products
The research shows that exposure to aluminium by using personal care products, like deodorant and sun protection, is very low: aluminium from personal care products barely penetrates the skin.
Most aluminum through food
People ingest most aluminium by eating food and drinking water, and lose most of it through their faeces. Aluminium is very common in the soil and is absorbed by crops. These include cereals, vegetables, cocoa and chocolate products. The level of aluminium in fruit and meat- and fish-products is generally low. Some clay-based food supplements, like powders or tablets, may also contain a high level of aluminium. Adults are therefore advised not to use intestinal cleansing clays on a long-term or frequent basis, and pregnant women should not ingest pregnancy clays.
Vaccins and medicines
Some vaccines contain aluminium, which is needed to improve the efficacy of the vaccines. Vaccinations are therefore also a source of exposure for young children. The safety of these vaccines is proven and all vaccines are continuously monitored. To adults, antacids containing aluminium can be a major source of exposure. The patient information leaflets for this type of antacids therefore contain the advice not to use them on a long-term basis.
