    There is no set time for taking protein shakes. However, having a pre/post shake is always ideal to fuel your body after a strenuous workout.

    In regards to the last half of your question, it all depends on how much grams of protein you consume in a day from the food you eat. How much do you weigh? what do you eat? i take protein shakes because sometimes i cannot always fit in my normal meal plan so taking the shake gives me those grams of protein i missed.

    natural one hit the nail on the head..

    get you a quality protien shake like ALN's nitrean or some other supplement company's and take it when best for you.

    I like them in three places..

    am..because i haven't had shit in my system for 6-8 hours and having protien and some carbs dumped into my gut immediately gets me off the ground and running. Plus if you can't EAT breakfast right off the bat like me... a shake is golden for that first meal.

    post workout..because immediately after a traumatic event (weight training) your body pools all it's resources both already in teh body and what's being processed (food) and directs it to the traumatized site for repair. I'm told this window is open after workouts from like 10-45 minutes after before things start to slow down. So protien right after a workout seems to "better" direct it to where you want it but again.. that's just theory.

    right before bed..because your body does the most growing when you're asleep and fueling it with plenty of those lovely little building blocks when it seems to use them the most seems to be beneficial as well!

    really you can't go wrong..but these are my thoughts on teh subject

    Protein co-ingestion stimulates muscle protein synthesis during resistance type exercise.

    Beelen M, Koopman R, Gijsen AP, Vandereyt H, Kies AK, Kuipers H, Saris WH, van Loon LJ.

    In contrast to the impact of nutritional intervention on post-exercise muscle protein synthesis, little is known about the potential to modulate protein synthesis during exercise. This study investigates the impact of protein co-ingestion with carbohydrate on muscle protein synthesis during resistance type exercise. Ten healthy males were studied in the evening after consuming a standardized diet throughout the day. Subjects participated in 2 experiments, in which they ingested either carbohydrate or carbohydrate with protein during a 2h resistance exercise session. Subjects received a bolus of test drink prior to and every 15 min during exercise, providing 0.15 g.kg(-1).h(-1) carbohydrate with (CHO+PRO) or without (CHO) 0.15 g.kg(-1).h(-1) protein hydrolysate. Continuous intravenous infusions with L-[ring-(13)C6]phenylalanine and L-[ring-(2)H2] tyrosine were applied, and blood and muscle biopsies were collected to assess whole-body and muscle protein synthesis rates during exercise. Protein co-ingestion lowered whole-body protein breakdown rates by 8.4+/-3.6% (P=0.066), compared to the ingestion of carbohydrate only, and augmented protein oxidation and synthesis rates by 77+/-17 and 33+/-3%, respectively (P<0.01). As a consequence, whole-body net protein balance was negative in CHO, whereas a positive net balance was achieved following the CHO+PRO treatment (-4.4+/-0.3 vs 16.3+/-0.4 micromol phe.kg(-1).h(-1), respectively; P<0.01). In accordance, mixed muscle protein fractional synthetic rate (FSR) was 49+/-22% higher following protein co-ingestion (0.088+/-0.012 and 0.060+/-0.004 %.h(-1) in CHO+PRO vs CHO treatment, respectively; P<0.05). We conclude that, even in a fed state, protein co-ingestion stimulates whole-body and muscle protein synthesis rates during resistance type exercise. Key words: muscle, protein synthesis, exercise, nutrition.
