Bioavailability & Absorption


Studies have shown that bioavailability of organically bound forms of selenium is greater than inorganic forms.


Generally about 80% of dietary selenium is absorbed by the body. However, factors like chemical species present in the diet, high dietary sulphur content (probably through competition owing to structural similarity) may retard selenium absorption (Sneddon, 2012; Briefing Paper, British Nutrition Foundation, 2001).
