A lot of people are confused...

From Wiki:
"Soy milk does not contain significant amounts of calcium, since the high calcium content of soybeans is bound to the insoluble constituents and remains in the pulp. Many manufacturers of soy milk now sell calcium-enriched products as well."

Calcium is added afterwards (natural???)...so if you make home-made soya milk, then there won't be much calcium.
