Biomarkers & Outcomes

Sleep Onset Latency

Sleep onset latency (SOL) is the objective measurement of the time it takes to transition from full wakefulness to the first stage of sleep.

Data and Device Infrastructure

Correlation Metadata

Correlation metadata tracks timing overlap between doses, logs, and outcomes without treating overlap as proof of causation..

Dosing and Logging

Adherence

Adherence is how consistently your real routine matches your intended stack, not how perfect your calendar labels appear..

Bedtime Dose Window

Bedtime dose window is the planned timing band for compounds taken close to sleep, where small shifts can change next-day outcome tracking..

Consistency Score

Consistency score is a practical indicator of how reliable your current routine is, combining timing consistency, adherence rate, and variance..

Cycle Aware Reminder

Cycle-aware reminders coordinate nudges with your active [cycle windows](/blog/understanding-dose-windows-and-cycles) so a skipped dose is interpreted in context, not as a hard failure by default..

Dose

Dose is the specific amount you take, which can be expressed as mg, IU, capsules, teaspoons, grams, or unit counts, depending on form..

Dose Window

A dose window is the acceptable intake band for a dose, not the same as a fixed clock slot..

Dosing Frequency

Dosing frequency is how often the body is exposed to a dose pattern, which can matter more than raw amount..

Evening Dose Window

Evening dose windows are for compounds that are typically better tolerated closer to the end of your active day..

Loading Phase

Loading phase is a short period where dose intensity is intentionally stepped up to reach a reliable signal faster..

Maintenance Phase

Maintenance phase is the period after active loading where the goal is stable benefit with lower side-effect risk..

Manual Dose Journal

A manual dose journal is a structured record you control when automatic captures are not enough for your protocol..

Medication Route

Route means how the active ingredient enters your system, and route changes can alter onset, intensity, and risk..

Morning Dose Window

Morning windows are when many compounds are dosed for energy, focus, or metabolism support, but response can vary with wake state..

Notification Action

Notification action is what you choose when a reminder fires, and that choice directly changes adherence quality..

Nutrition Route

Nutrition route means when and with what context your supplement is taken: fasting, with meals, or after specific food types..

One Tap Dose Logging

One-tap logging is a fast confirmation path designed to reduce friction while preserving signal quality..

Reminder Schedule

Reminder schedule is how [timing strategy](/blog/understanding-dose-windows-and-cycles) is set for routine follow-through without adding unnecessary alert burden..

Route of Administration

Route of administration is how a compound enters your body and changes timing, consistency, and safety assumptions..

Serving Size

Serving size is your base unit on paper; active dose is what you must compute from it..

Side Effect Note

Side-effect notes capture what changed, when, and how strongly, so later signals remain actionable..

Skipped Dose

Skipped dose is not always one event; it is often an intentional or accidental state that should be distinguished..

Stack Session

A stack session is a coherent block of time where behavior, dosing, and outcomes are interpreted together..

Titration

Titration is a controlled step-up plan used to find effective dose while limiting adverse overload..

Unit Normalization

Unit normalization converts mg, IU, µg, g, and liquid volumes into comparable dose language..

Placebo expectancy describes the psychological phenomenon where a person experiences perceived or actual physical changes simply because they anticipate a specific benefit from a supplement, regardless of its active biological efficacy..

Safety and Contraindications

Adverse Event

An adverse event is any symptom or sign that appears after a supplement change and is important enough to affect dosing safety, not just “I feel off.”.

Allergy Warning

An allergy warning means there is a meaningful possibility of immune reaction risk, ranging from mild sensitivity to immediate hypersensitivity..

Anticoagulant Interaction

An anticoagulant interaction is any supplement pattern that may increase bleeding tendency, especially when it overlaps prescription blood-thinners or procedural windows..

Contraindication

A contraindication means a specific ingredient or combination is likely unsafe enough to avoid, at least in the current context..

Dosage Ceiling

Dosage ceiling is the upper limit threshold that reduces escalation risk before side effects become more likely than benefit..

Duplicate Ingredient Risk

Duplicate ingredient risk appears when the same active or equivalent source is counted more than once across products..

Interaction Risk

Interaction risk is the chance that two or more compounds amplify, dampen, or mask each other's effects in your body..

Medical Disclaimer

Unfair provides educational guidance, not diagnosis or treatment decisions for medical conditions..

Pregnancy Warning

Pregnancy warning means heightened caution where evidence is limited and fetal risk could outweigh routine benefit claims..

Renal Risk

Renal risk reflects how kidney function affects supplement safety, especially for high burden compounds..

A foundation supplement refers to core nutrients or compounds that form the base of an individual's supplement stack, often addressing common dietary shortfalls before introducing specialized or experimental compounds..

Herbal Extract

Herbal extracts are concentrated forms where a plant is processed so the active compounds are more predictable than raw powders, but only if the label tells you what was standardized..

Ingredient Label
