Hi there,
Having too much protein in your body, can generate problems. However, this is only as a result to long-term abuse / over-use. Short-term signals can generate a very dark urine output, where long-term damage can relate to your liver, and in some instances the kidney.
It is important, however, to understand that it is not a dangerous act (generally) to partake in protein powder. The thrux of your protein intake should be as a direct result of your dietary behaviour (meals, beverages, etc). However, you may assist this (if your lacking protein in your overall meal intake), via taking these supplements....
If you are 'nervous' about the depth of measuring this kind of intake, and what is right for you - a generic rule for most people, is 30 minutes prior to a work out, immediately after a workout, and just prior to resting (sleeping) at night.
The reason that some problems can occur, is that your body can only handle / store so much protein, before it becomes over-inundated with protein; which is when it seeps into your urinary tract (as an example of why your urine can appear darker or abnormal, and become further acidic).
Three prominant results being Glycosuria, Albuminuria, and a wellknown one, Pyuria, can all be a result of high glucose, or high protein diet (Albuminuria a.k.a Proteinuria, often being an early sign of asymptomatic renal diseases).
Basically, though, you are fine if you take a -maximum- of 3 shakes per day. It is wise to measure the amount of protein your body should require.
There is a good post somewhere on this forum that addresses this. I will find it and post it up here for you.
Though, the moral of the story, is purely to moderate your intake. Long-term liver problems are well documented, kidney issues can occur as well. But, please do not let this deter you. It is just another precaution you need to acquire, as you would when beginning new exercises, and such.
Cheers.
