One study estimated that the additional amount of IGF-1 that might be absorbed by humans drinking milk from rBGH treatment, assuming no degradation and complete absorption, represents 0.09% of the normal daily production of IGF-1 in adults. On top of this, BGH is not active in humans, so even if it were absorbed from drinking milk, it wouldn't be expected to cause health effects.

We have been told it “does a body good,” but some scientific studies have found that contrary to popular belief, drinking milk may do more harm to our bodies than good. During supplementation with bST, the cow’s mammary gland takes in more nutrients from the bloodstream – producing more milk.

Before approving the use of rBGH in 1993, the FDA calculated a worst case scenario based on an infant drinking 1.5 liters (1.6 quarts) of milk daily, with complete absorption of intact IGF-1 protein and the maximum increase in IGF-1. It is not clear that drinking milk produced using rBGH significantly increases IGF-1 levels in humans or adds to the risk of developing cancer.

Alongside that, these kinds of stocks have higher premiums where it makes inexperienced investors difficult to identify poor investments. Recombinant bovine growth hormone (rBGH) or recombinant bovine somatotropin (rBST) refers to bovine growth hormone that is made in a lab using genetic technology. Since these products are not labeled as containing rbGH / rbST, most consumers have no idea that a growth hormone intended to induce dairy cows to be more productive is in much of their milk, cheese and yogurt. It is because it is a protein that it is broken down by pasteurization and digestion. RBGH is given to cows to increase milk production, which helps meet consumer demand for the beverage, as well as helps maximize profits for dairy farmers.
