What do the states mean?+
- Solid: well studied, and it works.
- Half-there: the science is still forming.
- A ghost: almost no real studies.
- Hollow: well studied, and it does not work.
- A cord: the pair itself has been tested together.
- Air: nobody has ever tested this pair.

What you’re seeing
- Magnesium renders half-there: for sleep, the science is still forming.
- Vitamin E renders half-there: for mood, the science is still forming.
- The woven cord is the rare part: four trials gave both together, and the pair came out ahead of placebo.
You can tell before you read a word.
Magnesium + L-theanine are sold together in the same aisle. No trial has ever tested the pair. When that is true, we draw nothing between them. The nothing is the review.
