Permissibility of Krill Oil

Assalamualaikum respected Ulama.
I suffer from rheumatoid arthritis which has been quite severe and modern medicine hasn’t been able to control it. A friend who also suffers from the same disease has found significant improvement through the supplementation of high quality krill oil more specifically the brand named Dr Mercola Krill oil. There are a few small studies on the benefits of krill oil for such a disease, however nothing to the scale for it to be deemed reliable enough for it to be accepted within modern medicine practices. As a hanafi would it be permitted to trial this supplement as it is derived from shellfish? The exact type is not stated so it is unknown whether this is derived from prawns or other shellfish .
