We present an improved calculation of the light element abundances in the framework of Big Bang nucleosynthesis as a function of the Higgs vacuum expectation value v. We compare the methods of our calculation to previous literature including the recently published work of Burns et al. [1]. The PDG result for the 4He abundance can be explained within 2σ by −0.014 ≤ δv/v ≤ 0.026, for deuterium we find the constraint −0.005 ≤ δv/v ≤ −0.001. These bounds are more stringent than what was found earlier.
