In this article, we study the existence of normalized solutions to the following Choquard equation with \(L^2\) -constraint: \(\begin{aligned} {\left\{ \begin{array}{ll} -\Delta u-\lambda u=(I_\alpha *F(u))f(u),\ \ x\in \mathbb {R}^N,\\ \int _{\mathbb {R}^N}u^2\textrm{d}x=c, \end{array}\right. } \end{aligned}\) where \(N\ge 3\) , \(c>0\) is given in advance, \(I_\alpha : \mathbb {R}^N\rightarrow \mathbb {R}\) is the Riesz potential of order \(\alpha \in (0,N)\) and the unknown parameter \(\lambda \in \mathbb {R}\) appears as a Lagrange multiplier. We weaken the previous \(L^2\) -supercritical conditions and develop robust arguments to establish the existence of normalized solutions to the above equation for any \(c > 0\) .
