1) I think the amount of cellulose found in those vitamins are negligable amounts…the cellulose found is very often what the capsule is made out of. I wouldn’t worry too much unless it is one of the top ingredients listed. The “nature’s way” brand is a better one because it only has cellulose as a bad ingredient.
2) I would stop the bio zinc because it contains rice and “other ingredients.” Who knows what the other ingredients contain? The solgar brand is an alternative as an example.
3/4) Read #1
5) I would get a non-vitamin shoppe brand of fish oils; the carlson laboratories is one of the best brands. They even have a liquid fish oil that you can take that isn’t in a capsule.
Hope this helps. The vitamin shoppe brands contain the most “junk” ingredients typically and finding one without these is sorta tough.
