The Bottom Line

For most people: Start with a dual-extracted reishi elixir (adenosine pathway) or NOW Magnesium Glycinate (budget option). Neither has shown tolerance in the studies available, though none of those studies ran long.

For racing thoughts: Add Thorne L-Theanine.

For stress-related sleep: Add ashwagandha (be patient—takes weeks).

Avoid melatonin for regular use (tolerance), valerian for long-term (GABA tolerance), and "sleep blend" products (sub-therapeutic doses). The best supplements work with your body's natural systems, not against them.
