Treat anythign you hear from supplement manufacturers with skepticism – remember their main aim is to sell more of their products.
you may want to check out the research on the high molecular weight low osmolarity carb source – http://www.myprotein.co.uk/?page=article&id=227 – being an example available in the UK
Research suggest postworkout these are highly efficient.
At the amino acid level leucine has been demonstrated as one fo the more effective post workout protein synthesis aminos – so may be worth looking at.
The jury remains out on glutamine – personally I find it can help ward off infection that sometimes seem to be triggered when you workout extrmeley hard so some wont hurt!
A 100 kg man on average cant assimilate more than 30g protein from a complex source in one sitting – so there is no point going overboard on the protein supplementation – you are better off spreading over 6 or more meals during the day – dont be fooled by supplement selling propaganda – clearly they want you to use more – swallowing 30 BCAA tablets across an hour will only make your urine expensive – you simply cannot absorb that amount.
and finally some research suggests that a good old full glass of milk with milo mixed in is not that bad postworkout post workout and its a damn site cheaper! Whatever you take get it in within 30 min postworkout – thats the sensitive time.
