Kelp powder for RFT?

[Autiwara]

I sometimes give my redfoot dried (rehydrated) seaweed and he loves it, but I saw this kelp powder at work and I'm wondering if it would be beneficial for him? I know probably most can't read norwegian but the important stuff is still understandable I think. I attached a pic of the kind of kelp it is, the powder is originally for dogs but it's just 100% dried, ground up kelp.

I think it's fine to mix a tiny bit with greens as a supplement and food enrichment once in a week or two. But not necessary.
