Pediasure powder _ Vanilla

Hi,
I am in Burbank, CA. In need to know where can we get Pediasure powder. I searched in all american stores like vonz, albertsons we get only pediasure in liquid form. But where can we get the powder that we used to get in India. Can we get in any Indian grocery shops? If so, in which indian store ? like in Loz feliz , Artesia ?

Waiting for ur reply.....

Thank you.
