Let H be a finitely generated pro- p group. We prove that, if H/Z₍-₁ (H) is a powerful group, then the n-th terms of the lower p-series and the lower central series of H are powerfully embedded in H. As a consequence, we obtain that if H/Zₙ (H) is a p-adic analytic pro-p group for some positive integer n, then H is a p -adic analytic pro- p group. Furthermore, we extend these results to pro- p groups that are not necessarily finitely generated, provided some additional conditions are imposed.
