The best way to mix is in a blender because a more vigorous mix increases solubility and may be required to dissolve all the particles in the formula. The alternative is to first mix the formula in hot water, because heat increases solubility. Alpha ENF contains no animal products. Strict vegetarians will benefit from the boost of nutrients that the formula supplies, especially nutrients that may be scarce on a vegetarian diet. These include amino acids, iron, vitamin B12, vitamin D, and trace minerals.
Dietary protein supplies amino acids, the real nutrients.
Proteins are mostly responsible for food allergy and have been specifically eliminated from the formula. Alpha ENF supplies all the essential and non-essential amino acids in a rationally balanced mix of the highest purity. For those that eat less than 450 grams per day, your need for amino acids is probably covered - the 25 gram estimate is probably higher than your actual need, and the formula amino acids are more efficiently absorbed and utilized than proteins in food. Since the amino acid pool in the body is recycled, net loss of amino acids is estimated to be only 2 grams per day. If extra Amino acids are required, Alpha AAX can be added to any other Alpha formula to boost intake.
