Gabriel Bertrand (born 17 May 1867 in Paris, died 20 June 1962 in Paris) was a French pharmacologist, biochemist and bacteriologist.

Bertrand introduced into biochemistry both the term “oxidase” and the concept of trace elements.

The laccase, a polyphenol oxidase and an enzyme oxidating urishiol and laccol obtained from the lacquer tree, was first studied by Gabriel BertrandGabriel Bertrand on isimabomba.free.fr (French) in 1894.Science and civilisation in China: Chemistry and chemical ..., Volume 5, Part 4 By Joseph Needham, Ping-Yü Ho, Gwei-Djen Lu and Nathan Sivin, p. 209

Bertrand's rule refers to the fact that the dose–response curve for many micronutrients is non-monotonic, having an initial stage of increasing benefits with increased intake, followed by increasing costs as excesses become toxic.Does Bertrand's rule apply to macronutrients? D Raubenheimer, K.P Lee and S.J Simpson, Proc Biol Sci. 22 November 2005; 272(1579): 2429–2434, In 2005, Raubenheimer et al. fed excess carbohydrates to Spodoptera littoralis and extended Bertrand's rule to macronutrients.

Along with Césaire Phisalix, Bertrand isolated the psychedelic drug bufotenin in 1893, though its hallucinogenic effects were not discovered until much later. In 1894, also with Phisalix, he developed an antivenom for use against snake bites.Le Musee Pasteur Césaire et Marie PHISALIX, deux chercheurs comtois
