How We Compare
Every comparison is graded on the same dimensions.
- Ingredients — what is actually in each option
- Dosage / amount — per-serving comparisons, not bottle sizes
- Form — chemical form, delivery and absorption context
- Third-party testing — what has been verified, and by whom
- Evidence quality — human trials, graded and disclosed
- Price / value — cost per effective dose
- Ease of use — practical differences in daily life
- Who it may suit — goals and contexts, not one-size claims
- Limitations — what the evidence cannot tell us
A comparison does not always have a winner. The honest answer is often “A is better for X, B is better for Y” — and sometimes the evidence is simply insufficient to declare one superior. We will say so when that is the case.
