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.
The full scoring method: How we score
Can you take omega-3 and garlic together?
Tested together, early signs.

What you’re seeing
- Omega-3 renders hollow: for heart, it is well studied and it does not work.
- Garlic renders half-there: for heart, the science is still forming.
- The woven cord is the rare part: one trial gave both together, and the one trial so far came out ahead of taking nothing.
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.
