The research

What the evidence
actually says.

Some of our ingredients have real trials behind them. Others have long traditional use and a mechanism that makes sense. Both are fair reasons to put something in a formula, but they are not the same standard of proof, so this page grades every one of them and says which is which.

Strong

Multiple randomised controlled trials, usually pooled in a meta-analysis, with consistent results in humans.

Moderate

Human trials exist and point one way, but they are few, small, or the effect depends on conditions.

Traditional

Long use and a sensible mechanism, without the human trial data to call it proven.

Ingredient by ingredient

Where the strong
evidence sits.

BacopaStrong

Faster processing and better memory consolidation, pooled across 437 people.

A meta-analysis of randomised controlled trials found shortened Trail B times and reduced choice reaction time. Effects build over weeks rather than appearing on day one.

Kongkeaw et al., Journal of Ethnopharmacology, 2014 · meta-analysis of RCTs, n=437
AshwagandhaStrong, with a caveat

Reliably lowers cortisol. Whether you feel less stressed is a separate question.

Meta-analyses covering hundreds of adults show significant reductions in serum cortisol against placebo. One pooled analysis of eight trials found cortisol fell but self-reported stress did not.

We include it for the cortisol data. We are not promising you will feel calmer.
Systematic reviews and meta-analyses, 2024 to 2025 · 9 RCTs n=558, 15 studies n=873, and 8 RCTs n=488
L-TheanineModerate

Shifts alpha-band brain activity toward relaxed alertness. Works best paired, not alone.

EEG studies show increased attention-related alpha activity. The clearest attention benefits appear when theanine is combined with caffeine rather than taken on its own.

Signal has no caffeine. Here theanine is paired with tyrosine to take the edge off drive, which is a different job from the caffeine studies.

L-TyrosineModerate

Helps most when you are depleted, not when you are already fresh.

A dopamine and noradrenaline precursor. Human trials show cognitive benefit under acute stress, multitasking or sleep loss, and little measurable effect at baseline.

Multiple randomised trials under stress and cognitive load · effect is condition dependent
Prebiotic fibreStrong

PHGG and inulin change the gut environment measurably.

Both are well studied fermentable fibres with human data on stool consistency, regularity and short-chain fatty acid production. PHGG is the better tolerated of the two at dose.

Established human trial literature on partially hydrolysed guar gum and chicory inulin
Tulsi and gingerTraditional

Long use, sound mechanism, thinner human data.

Both have centuries of documented use and reasonable mechanistic support. Neither has the pooled trial evidence that bacopa or ashwagandha do, and we are not going to pretend otherwise.

How they work together

Pairs that do more
than the parts.

A blend is not a list. These combinations were chosen because one ingredient changes what another one does.

Amla+Citrus bioflavonoids

Vitamin C that stays useful

Bioflavonoids occur alongside vitamin C in whole fruit and are studied as cofactors for its absorption and antioxidant recycling. Isolated ascorbic acid arrives without them.

PHGG+Chicory inulin

Each fibre feeds a different population

They ferment at different rates and feed different bacteria. Inulin alone at dose causes bloating in a lot of people. Splitting the load across both is why the fibre is tolerable.

Prebiotic fibre+Live cultures

Feeding what you just added

A probiotic without a substrate has nothing to eat. Pairing cultures with fermentable fibre is the difference between adding bacteria and supporting them.

L-Tyrosine+L-Theanine

Drive without the edge

Tyrosine supplies the precursor for dopamine and noradrenaline. Theanine shifts brain activity toward relaxed alertness. The intent is focus that does not arrive as agitation.

Greens iron+Vitamin C

Plant iron you can absorb

Non-haem iron from leaves and algae absorbs poorly on its own. Vitamin C in the same drink is one of the best documented ways to improve its uptake.

Algal DHA+Magnesium

Structure and signalling

DHA is a structural fat in neural membranes. Magnesium is a cofactor in hundreds of enzymatic reactions including nerve signalling. One builds, the other runs.

Check your batch

Seven in ten labels
in this country are wrong.

A peer-reviewed study of thirty-six supplements sold in India found seventy per cent mislabelled and fourteen per cent carrying fungal toxins or pesticide residue. Every brand writes third-party tested on the pouch. Almost none of them mean your pouch.

Quality and testing

What we test,
and what we do not.

01

Every batch

Heavy metals and microbial limits, at an FSSAI recognised laboratory, before the batch is released.

02

Batch code linked

Reports are published against the batch code printed on your pouch, so you check yours and not an average.

03

Standardised, and the figure is printed

Ashwagandha at 5% withanolides, turmeric at 95% curcuminoids, amla at 40% tannins. People do not distrust the tradition. They distrust being asked to take the potency on faith.

04

What we do not claim

We have run no clinical trial on the finished blends. The research on this page is on ingredients, not on our product.
