Probiotics gives lactobacillus acidophillus & bifidobacterium. whey: beta lactoglobulin & alpha lactalbumin. can both provide similar benefits?

No: Probiotics and whey provide different benefits. They both have "lacto" in their names, which may be the source of your confusion. Lacto means related to milk. Lactobacillus is a bacteria that can grow in dairy products. Whey is the thin, clear liquid that is left when milk has curdled; it is high in protein. Probiotics are good for intestinal health. Whey is primarily a protein source.

No benefit: There is lack of objective evidence that probiotics provide any benefit. Have a healthy diet, exercise 30 minutes/day, drink plenty of water, have safe sex, no tobacco alcohol weed or street drugs. For nutrition: http://www.choosemyplate.gov/.
