An upper bound on the renormalized coupling constant α≤3πε+O(ε2) is found in quantum electrodynamics in n=4–2ε space-time. Analogous bound is obtained for a la Speer regularized Wess-Zumino model. The obtained bound means the triviality of QED and the Wess-Zumino model in the limit of the regularization removing.
