What protein powder/shake is most effective?

I can't say about "best", as that's relative to what your goals and preferences are, but I personally find myself most happy with Plant Fusion. It is Lactose, Cholesterol, Dairy, Soy, and Gluten Free, with 21g of protein per scoop. Very finely milled, and there's an unflavored powder that would mix well into a variety of recipes. I presently use the vanilla powder and mix a scoop with 1.5 cups of almond milk, 1 medium banana, and a half cup of strawberries to make a shake. Ends up around 340 calories. Add some peanut butter to increase that number quite a bit.

#ItWorks! You can even bake with it. It has exactly the amount of protein and nutrients needed. These products are amazing and has helped aid in my weightloss.

The best shake is the one on the dance floor. Whoop Whoop ! Happy Saturday.

Protein powder is a somewhat personal choice.....what's important to some might not be as important to others. Some want cheap, others want taste or mixability. I do a fair amount of research of protein powders on the bodybuilding.com forums mainly because those folks know protein powder inside and out....it's the staple for what the do. It has worked out well for me. I wanted a good clean whey protein powder that had little or no sugar or carbs, and mixed easily with water in a shaker bottle. I've been using Optimum Nutrition Gold Standard Whey - I like Chocolate Mint and Double Rich Chocolate.

24g of protein per scoop
120 cals
1g fat
3G carbs
2g sugar

It is somewhat pricey at $56 per 5lb tub but that has 72 servings so it's basically about $.75-.80 per 24g of protein shake. And it's a very very good whey protein. Mixes easy, no clumping....tastes fine with water...even better with skim milk. You can get cheaper protein powder for sure at Walmart or wherever but the quality is not going to be nearly as good.

There are a bunch of good proteins out there.....just do a little research and see what others say about the powder they us.....good luck!!

There is not most effective.

Whey is not a magical source of protein to cake on muscle within minutes. All it is, is one of the cleanest and most available protein sources on the market.

I advise you to check the labels on the make if you buy some. If a serving size is 50g... and there's only 25g of protein in that serving, and you're eating/drinking 25g of UNKNOWN trash. So, make sure you get a reputable brand and not the Wal-Mart crap either.

Protein bars are the same way. The cleanest bars without added crap in them are Quest Bars & Oh yeah! bars.

I would head to your local GNC or nutrition/vitamin store and talk to the people there! Often times they can even have you sample different products or have return policies in case you end up not liking the taste! Plus they can show you which products will match your goals and are just good sources of knowledge in general!
