Beetroot / dietary nitrate

Moderate

the underrated endurance and blood-pressure trick

Marketed
Evidence
Better than its hype

Marketing intensity 45 of 100. Evidence strength 70 of 100. Verdict: Better than its hype.

Quietly effective and under-marketed. The nitrate in beetroot genuinely lowers blood pressure a little and improves endurance - a rare case of substance over hype.

L-citrulline

Limited

the pump amino acid — better than arginine, oversold for pumps

Marketed
Evidence
Slightly overhyped

Marketing intensity 60 of 100. Evidence strength 45 of 100. Verdict: Slightly overhyped.

A legit nitric-oxide booster with some real recovery and endurance signal, but the evidence is mixed and single pre-workout doses often do nothing.
