Abstract
Unitarity bounds for the B → πℓνℓ form factors are generated. The interpolation formula for the bounds constrained by lattice results is obtained. We note that the bounds are rather restrictive although do not allow for a definite conclusion on the needed f+(q2) functional behavior in the entire physical region.
