Only the "oil blend" has fish oil in it, the powder is vegan. I don't know what that really means since their website is so awkwardly designed and vaguely written I can't tell if they're separate products or two parts of the same product.
I don't see how it's any different/better than Vega's "One" powder though. It kind of bugs me that Vega's been making a complete nutritional drink for years and suddenly Soylent is getting attention like they're the first to try, despite their product being inferior in numerous ways (flavour, nutrient content, allergens, to name a few).
I'm quite fussy so I doubt I'd like it. But I'd be willing to try it. Seems there's a vegan option on their website when ordering. Apparently though they're behind on orders and not yet selling to Australia. Surely someone else will step into the void with the same kind of product if there's a market for it though.
would be a great product for some, if it was vegan.
