[Question] Does freeze-dried mussel powder have good stuff that vegan diets don’t?

Personal background for this question:

  • I’m a vegan for ethical reasons, meaning that I don’t want to contribute to the farming of beings that can suffer.

  • I think that oysters and mussels probably aren’t sentient.

  • Oysters and mussels seem pretty disgusting to me.

  • I would like to be healthy.

  • I am already taking B12 and Omega-3 supplements.

Oysters and mussels seem like they might have important nutrients that one otherwise can’t get in a vegan diet without supplementation, just because that animals are different to plants/​fungi/​etc., and humans ate animals in the EEA. However, due to their disgustingness, I can’t quite bring myself to eat them.

Luckily, it turns out that one can buy capsules that contain freeze-dried green-lipped mussel powder. I’m pretty excited about this prospect, but am somewhat worried that the freeze-drying and powderifying process would destroy various nutrients, or render them mysteriously ineffective in the ways that I gather vitamin pills are mysteriously less effective than vitamins in food. I also imagine that maybe the really important nutrients are only found in (say) land mammals. Can anybody shed light on this?
