If the gelatin capsules in Algin are a concern, have you considered getting your own empty, vegetarian capsules and filling them with Algin? Just dump the Algin out of the gelatin capsule into one of your empty vegetarian capsules. You can buy empty vegetarian capsules at pharmacies and such. I'm sure NSP could tell you what size capsule they're using -- it looks like Size 0 or maybe Size 00 -- but I"m not certain on that.

I'm not trying to be flippant here, it just seemed an easy solution to your dilemma. And it doesn't take alot of time to fill capsules. I'd just use sterile gloves and a clean, sterile surface while doing this to avoid any contamination.
