Each NAMOOS Mango Peach can lists four actives in milligrams. This page

published human studies on those ingredients - who was
studied, at what dose, for how
long, and what was reported. NAMOOS

NAMOOS is a productivity drink made in the UAE. It is not an energy drink.

Where a study used a different dose than the can, that is stated on the row. Results are not a guarantee of how you will feel.

Reported
Fewer omission errors (p=0.04) and commission errors (p=0.03) on CPT-II vs placebo at 250 mg*

In a 28-day randomised, double-blind, placebo-controlled study, healthy adults taking 250mg Cognizin® daily showed improved attentional performance measures - including fewer errors while on task - compared with placebo.*

L-Theanine - 175 mg per can

L-Theanine is an amino acid associated with tea (green tea extract on the NAMOOS label). Each
can has 175mg, next to 35mg Natural Caffeine.

Rhodiola rosea - 200 mg per can

Rhodiola rosea is a botanical root extract. Each can lists 200mg. The human trials below used a

We list Rhodiola at 200mg so the dose is on the label. We do not claim the 370mg or 576mg SHR-5 results for this can.

Natural Caffeine - 35 mg per can

B VITAMINS (on the label)

Each can also includes vitamins B3 (8mg), B6 (2mg), B5 (2mg) and B12 (2µg).
These are nutrient function lines from the authorised list - they attach to the vitamin, not to NAMOOS or Cognizin®.

Pantothenic acid (vitamin B5) contributes to normal mental performance.*
Vitamins B3, B6 and B12 contribute to normal psychological function and to the reduction of tiredness and fatigue.*
