Who should buy which
Buyers who want a credible all-purpose magnesium without researching which form to take, and who can tolerate aggressive brand marketing in exchange for a well-formulated stack.
You already know you want a specific form (glycinate for sleep, threonate for cognition), or you prefer minimalist clinician-brand aesthetics like Thorne or Pure Encapsulations.
Buyers wanting a multi-form magnesium stack with Nordic clean-supplement aesthetics, especially for combined sleep + cognitive + recovery use cases.
You already have a structured magnesium protocol (Thorne single-form, BiOptimizers Magnesium Breakthrough), or you want the cheapest credible option (Now Foods at $12).
