Bearbrand junior

Hindi ko ma-recall kung ano exactly ang Bearbrand Junior na tinutukoy mo, is it a milk formula, a supplement, or something else? A few of us moms talk about different brands all the time kaya ayaw ko mag-assume, pero if you can give me more details (like what it's for, nutrition, vitamins, etc.), mas makakatulong ako based sa experience ng circle ko! What's your little one need it for?
