Query: Misleading! Careful before you buy

When the bottle arrived, reading the small print on the back, it turns out that each capsule only contain 100mg (NOT 500mg!) of the active ingredient (Phosphatidylserine). The other 400mg of the "PhosphatidylSerine Matrix" is Soybean Oil and other filler (Glycolipids and Phosphatidylcholine). I feel ripped off! It's not like these are cheap.
