Anything as Effective as NaturDAO?

Has anyone found anything as effective as NaturDAO for DAO sources? Any of the other brands, desiccated beef kidney, etc?

My 1,000,000IU NaturDAO is my ride or dieeeee, but it’s pretty costly to take 4x daily, and I’d like to explore other options based on your recommendations of what you guys have found effective.

Thanks, friends :)
