Biotin-Flaxseed

You know you hear so much about different meds, but my doctor told me I could start taking both of these. I asked liquid or capsule, he said either. So now I am at Vitamin Shoppe dot com and I see they have the Biotin in 5mg or 300mcg, so I take it the 5mg is stronger, but in the Flaxseed, didn't I see someone post we don't absorb the liquid? I also read we don't break down capsules in my pouchy now, but I find that odd, as my actigal from surgery is capsule and supplied from my surgeon. So let me hear from ya all, whats the myths......
