For $1 p 2$ we obtain sharp lower bounds for the uniform norm of products of homogeneous polynomials on $L_p(\mu )$, whenever the number of factors is no greater than the dimension of these Banach spaces (a condition readily satisfied in infinite-dimensional settings). The result also holds for the Schatten classes $\mathcal S_p$. For $p>2$ we present some estimates on the constants involved.
