The biological value of protein (BV) refers to what percentage of that protein is actually used by your body when you eat/drink it. When you think of it this way, a value of 0 to 100% makes a lot of sense; however, you will see nutritional supplements and other places using percentages over 100%.
Obviously, your body can’t absorb more than 100% of a protein, so how are they getting that number? It all boils down to eggs. See, eggs contain all the essential amino acids in about the same proportions your body needs, so it was deemed the gold standard.
If you rate eggs by how much protein is actually utilized by the body, they have a score of 94%.
Since they’re the gold standard for comparing and rating other protein sources, though, a separate type of BV measurement exists using eggs as a baseline. In the separate system, BV is based on this comparison with an egg. It’s important to note that the “egg system” doesn’t change the meaning of biological value, just the manner in which it’s expressed.
An egg has a BV of 100% in this second form of measurement. It follows, then, that any protein source with a BV higher than 100% must be better than an egg. And that’s exactly right. There aren’t many, but some “super proteins,” like whey protein, have biological values over 100%.
Because whey protein is so incredibly efficient and useful, it’s a key part of the Olumia Life Nutrition and nutrient timing plan.
