```Who knew that fish lurk in some brands of orange juice? If you want to avoid animal products altogether, skip any juices enhanced with Omega-3’s; some brands like Tropicana’s Heart Healthy Orange Juice get those amino acids from fish oil and gelatin. Also, the vitamin D in some enhanced juices is derived from lanolin, a natural oil in the fiber of sheep’s wool. Coca-Cola juices contain lanolin-derived vitamin D, while Tropicana juices are fortified with synthetic ingredients and Pepsi-Co juices contain no animal products or by-products at all. Typically, vitamin D3 is animal-derived.```
