Would anyone know where I could purchase modest amounts
Sodium and/or Calcium Caseinate online,in the USA,for relatively
cheap prices?I've seen it listed on some chemist supply sites but
I think in the neighborhood $80 for 500g is a bit steep!I've put
feelers out into the body building community as well hoping for
for a few leads.Any info would be appreciated.Thank you.

What quantity and what quality? I've seen calcium caseinate listed as a supplement almost everywhere - you could probably buy it in any natural food store or bodybuilding supplement supplier. If you need larger quantities, there are manufacturers that specialize in pure food products such as this. One is here - http://nutrafoodingredients.com/products/protein/calcium-caseinate

What you are paying for from the chemistry supply sites is guaranteed purity and analysis.
