Is it a meaningful further enhancement to add: “Extend the sharing of such benefits [antiviral supplements] where applicable among all life forms on all timelines?” That would help counter adverse manipulations of all kinds leading to impairments and extinction of species.

This, indeed, is a deserving addition and reflects your divinity and stewardship in a divine capacity for all creations in harm's way. So this would be a strengthening to give the divine realm even greater latitude to extend the benefits of human healing requests, to be amplified by all higher selves everywhere, to do the same.
