How to read a Supplement Facts panel like a skeptic: proprietary blends, standardization, fairy-dusted doses, and what "clean label" and regulatory terms actually mean.

An NPN means Health Canada reviewed a product's safety, quality, and claims before it went on sale. It tells you a dose cleared a permitted minimum, not where that dose sits in the studied range. Here's the arithmetic that answers the second question, using our own formula as the worked example.
The arithmetic of a Supplement Facts panel: serving-size math, what %DV does and doesn't tell you, the elemental-weight trap, upper limits, and the warnings that are supposed to be there.
"Clean label" gets used as a vague marketing word. Here is what it actually means in practice (no proprietary blends, disclosed doses, named forms) and how to check for it yourself on any Supplement Facts panel.
A twenty-ingredient formula can deliver less than a five-ingredient one. How to judge a supplement by its studied doses, not the length of its ingredient list.
How Canada regulates focus and cognitive supplements as Natural Health Products: what an NPN is, why it matters, and why some products sold to Canadians don't have one.

Ingredients covered
Full evidence-graded profiles for the ingredients discussed across these articles.
A choline-donating compound the body uses in cell-membrane and neurotransmitter pathways. It is studied as a focus and mental-energy ingredient.
A traditional herb standardized for compounds called bacosides. It is studied mainly for memory and learning over sustained daily use, not for same-day effects.
An adaptogenic herb standardized for rosavins and salidroside. Its studied benefit is narrow: reducing stress-related mental fatigue and helping sustain output during genuinely demanding stretches (night shifts, exam load), not lifting baseline performance in a rested, unstressed adult.
An amino acid found in tea leaves. It is studied for promoting a calm, settled kind of attention without sedation, which fits a stimulant-free focus direction.
A foundational fat-soluble nutrient, not a same-day nootropic. There is no reliable evidence it sharpens focus in people who already have adequate levels, but low vitamin D status is common at Canadian latitudes in winter and is associated with poorer cognition, so it fits as foundational "status insurance," not a cognitive active.
The nervous-system B vitamins (B6, folate, and B12) support normal neurological and psychological function and normal nutrient metabolism. Measurable cognitive benefit is strongest where baseline status is low or homocysteine is elevated (typically older adults); it is limited in young, well-nourished people.
