Third-Party Testing

Every batch at Zuma Nutrition is independently tested by Advanced Laboratories (ISO-accredited) for purity and safety. Heavy metals (lead, arsenic, cadmium, mercury) are substantially exceeding purity expectations — far below California's strict Prop 65 safe harbor thresholds (Lead: 0.5 µg/day, Arsenic: 10 µg/day, Cadmium: 4.1 µg/day, Mercury: ~0.3 µg/day). Microbial results are exceptionally clean — no detectable pathogens (E. coli, Salmonella, Staphylococcus aureus absent) and counts that set the bar for clean products in the industry.

Highest quality on the market

Lots of bad L Theanine supplements on the market. This formula you can feel the strength and effectiveness of this high quality sun theanine. I take one - two capsules every 4 hours throughout the day and it helps me manage my busy work schedule and daily stress. David B.

Love it. Can't live without it.

Not only is L-theanine a precursor to dopamine (the motivation nuero -transmitter) but it also aids in the transport of GABA (the calming nuero-transmitter) to it's receptor site. So I get clear, driven and calm. This stuff is so good I dump it under my tongue swish a touch of water and it soaks up immediately! Bass B.
