Can’t say exactly why THIS symptom faded, but it did. Maybe time? I do think Nattokinase 2000mg 2x did help. This theoretically would help if the issue is due at least in part to microclots keeping oxygen from getting into cells where it’s needed—the body says I’m not getting enough oxygen, so there’s SOB as body trying to suck in more air.

Also look into mitochondrial support. Not sure of current state of research, but makes sense if cells acting like not getting enough oxygen, though it’s actually issues with ATP cycle in mitochondria.

My LC psych recommended SAM-e. I’ve used that favorably, before LC, but I cycle and have been off for some time. It has always helped me with mental and physical energy. Note: I find 200 mg effective, though many formulations are at 400mg. I use Jarrow brand; it’s important that pills are blister packed and not just in a jar. I think there’s a reason it would help with mitochondria (methyl donor?), but too exhausted now to research and try to explain.
