Neutonic Smarter Energy Drink

What it does

Neutonic Smarter Energy Drink is the carbonated can Neutonic sells on its Australian store (/en-au/). It has the same five actives as the brand's Productivity Drink, but 106mg caffeine per 330ml can instead of 120mg. The product page says each can 'Contains 1 serving', and its label advisory reads: 'Contains caffeine: 106 mg per 330 mL serve (32 mg/100 mL). Not recommended for children, pregnant or lactating women, or individuals sensitive to caffeine. Consume no more than one can (330 mL) per day.' On the Australian store it comes in packs of 12 cans in Tropical Ice or Orange Sunrise. Besides the actives, the ingredient list names carbonated water, the acidity regulators citric acid and malic acid, natural flavour, the sweeteners sucralose and acesulfame potassium, and the preservatives sodium benzoate and potassium sorbate; the caffeine comes from green coffee bean extract standardised to 98% caffeine. The 'what's inside' panel says '100% RI 8 B Vitamins', but the full ingredients list names six: niacin, pantothenic acid, riboflavin, vitamin B6, thiamin and vitamin B12 (as cyanocobalamin), with no folate or biotin. The vendor says the drink is suitable for vegetarians and vegans.

How it works

Caffeine (106mg) blocks adenosine receptors; at low-to-moderate doses it consistently improves alertness, vigilance, attention and reaction time, with less consistent effects on memory (McLellan 2016, a narrative review). L-theanine (400mg, twice the top of our 100-200mg reference range) is an amino acid from green tea: in an 11-study meta-analysis, caffeine plus L-theanine had moderate effects versus placebo on alertness and attention-switching accuracy (Camfield 2014), but Foxe 2012 found no added benefit over either compound alone, and in a controlled trial (Rogers 2008, PubMed 17891480) L-theanine did not significantly reduce caffeine jitteriness. Citicoline (500mg, as Cognizin®) is a precursor to acetylcholine and phosphatidylcholine; its memory evidence comes from older adults with inefficient memory at 1,000-2,000mg a day (Spiers 1996), and a Cochrane review found no evidence of an attention benefit in older adults with chronic cerebral disorders. Rhodiola is an adaptogen: small trials of the SHR-5 extract found less mental fatigue, but a 2012 systematic review rated every included study at high or unclear risk of bias, and the product page does not say which extract or standardisation is used. We have no reference dose on file for Panax ginseng. Neutonic Smarter Energy Drink itself has not been tested in a published trial; the vendor's claims rest on ingredient-level research.

What to expect

Caffeine's alerting effect typically starts within 15-45 minutes, the onset on our caffeine page; the vendor suggests a can before 'any high demand session', from a morning start to training. Each can has 106mg caffeine and the label says to consume no more than one can a day, so count it toward your daily total if you also drink coffee. The product page's FAQ and 'What to expect' copy still say 120mg; the label advisory and the 'what's inside' panel say 106mg, the figure we use. Citicoline's memory effects in trials were measured after 2-3 months, so a single can should not be expected to change memory. On neutonic.com's Australian store a 12-can pack costs $56.99 one-time or $48.45 a delivery on a subscription (Subscribe & Save 15%, delivered every 4, 6, 8 or 12 weeks), checked 2026-10-19. The product page says it 'ships from within AU', and the Australian shipping page says: 'Free shipping on all AUS stocked product subscriptions or single orders of 2 packs+.' and 'Standard shipping from $9 (varies by state). Orders are typically delivered within 1–3 business days from dispatch.' (neutonic.com/en-au/pages/shipping-returns, checked 2026-10-19).
