Is there any difference in fresh milk and pregnancy milk?

I believe pregnancy milk would be better than fresh milk in the content. For example , Frisomum Gold, which is for both pregnant & lactating mum. Frisomum contains prebiotics and probiotics to support healthy digestion, it also contains folic acid, iron, calcium, dietary fibre, DHA and AA to support your body’s changing needs and to provide a strong foundation for your baby.
