When to Whey?
Since it absorbs quickly you should consume it 30-60 minutes following a strength training workout. If you are just looking to add more protein into your diet, you should combine it with other foods to slow down the digestion. You could add it to oatmeal or use it to make pancakes like this recipe http://proteinpow.com/2015/02/ultimate-protein-pancake-recipe-post.html. Protein Pow has tons of protein powder based recipes http://proteinpow.com/.
No Whey? Other Protein Powder Options.
There are other sources of protein powder out there such as pea, egg white, brown rice, casein, soy, collagen and hemp which may work better for your body. I HIGHLY recommend that you first choose actual food as your protein source rather than supplements. If you live an on the go lifestyle or have dietary restrictions, a protein powder may be a choice that works for you.
Do you need more protein in your diet? You may actually be getting plenty in your diet already. The general consensus of how much you need is anywhere between .4g per pound of body weight to 1g per pound of body weight. It really depends on how active you are and what your goals are.
