SLEEP SIGNAL

L-Theanine vs Melatonin

Compare the ingredients by purpose, formulation context and safety questions—not by marketing superlatives.

Start with the goal

Before comparing products, define the actual problem you are trying to solve. A familiar ingredient list, large discount, or dramatic testimonial is not a substitute for evidence and fit.

Comparison checklist

Look for clear ingredient amounts, sensible claims, safety information, refund terms, realistic expectations and a price you are comfortable paying.
