Zynamite (Mangifera indica)
A 2020 RCT (Lopez et al.) found 300mg Zynamite acutely improved reaction time, attention, and working memory versus placebo. A 2019 sports performance study showed Zynamite + luteolin (Dynamine) improved repeated sprint performance and cognitive function under physical fatigue. Evidence base is small but growing — Nektium (the manufacturer) funds most research.
Mechanism of action
Zynamite is a patented extract of Mangifera indica (mango leaf) standardised to >60% mangiferin. Mangiferin is a potent polyphenol that inhibits catechol-O-methyltransferase (COMT), slowing the breakdown of dopamine and norepinephrine in the prefrontal cortex. This extends the active duration of catecholamines without increasing their production — a unique mechanism distinct from precursor-loading (L-Tyrosine) or synthesis-boosting (caffeine) approaches. Additionally, mangiferin has anti-inflammatory and antioxidant properties.

Human effect matrix
Based on human clinical trials only. Animal and in-vitro data excluded.
| Effect | Evidence | Magnitude | Studies |
|---|---|---|---|
| Reaction Time | moderate | Moderate | 2 |
| Working Memory | preliminary | Small | 2 |
| Physical-Cognitive Dual Task | preliminary | Moderate | 1 |
Evidence key: Strong = multiple consistent RCTs · Moderate = smaller/fewer RCTs · Preliminary = early trials or small n · Mixed = conflicting results

How to take
Stacking recommendations
Ingredients that pair well with Zynamite (Mangifera indica) and why.
Caffeine increases catecholamine release; Zynamite slows their breakdown via COMT inhibition. Together they produce a stronger, longer-lasting dopamine signal.
Tyrosine provides dopamine precursor; Zynamite slows dopamine metabolism. Supply + preservation for sustained catecholamine levels.
L-Theanine smooths out any overstimulation from Zynamite's catecholamine-preserving effects. Balanced energy without agitation.
Frequently asked questions
Is Zynamite just mango leaf extract?
Zynamite is a specific patented extract of Mangifera indica standardised to >60% mangiferin. Generic mango leaf supplements may contain far less mangiferin and are not equivalent. The clinical trials used Zynamite specifically.
Is the evidence independent or manufacturer-funded?
Most Zynamite studies are funded or co-funded by Nektium, the manufacturer. This is common for patented ingredients but means independent replication is limited. The existing trials are well-designed (double-blind, placebo-controlled) but should be interpreted with this funding context in mind.
Can I take Zynamite with caffeine?
Yes — this is actually one of the studied combinations. Zynamite + caffeine showed synergistic effects on reaction time in the sports performance trial. However, monitor your total stimulant load since Zynamite extends catecholamine activity.
