If you are prone to constipation as opposed to diarhea then I would say, from experience, any oil type vitamins/supplements will tend to counter rather than increase constipation. Any hard, dry, pill type, can be hard to digest and possibly increase constipation (especially minerals). Digestives aids can offset some of the challenges and increase the absorbtion by the body.
You listed several fish oils, but hopefully that is just a list of options and your aren't intending to take all of them daily. My Natural Care doctor discourages taking too much fish oil. Some is very good for you, too much is not. I am on one tablespoon a day of cod liver D (equals 3000 IUs of vitamin D). Just a cautionary note.
I would also suggest phasing in anything your taking so you are more likely to pinpoint which one may give you trouble if any do (I give myself 3 days minimum on a supplement before adding another). Nothing like adding five or more supplements to your diet and then suddenly blocking up and having no idea which new item was the culprit.
