    Formula Used

    This calculator uses a rule-based timing model anchored to your day. It converts times into minutes after midnight, applies supplement-specific offsets, then scores adherence and likely fit.

    1) Time conversion
    M = 60 × hour + minute

    2) Suggested time
    Ts = A + O
    Where A is the anchor event time and O is the timing offset.

    3) Timing window
    Window = [Ts − B, Ts + E]
    B and E are early and late tolerance minutes.

    4) Conflict penalty
    P = Σ pi
    Penalties increase when stimulant timing threatens sleep or minerals compete.

    5) Per-supplement score
    Score = max(0, 100 − P − D)
    D reflects practical drift from the ideal anchor.

    Common anchors
    First meal, largest meal, workout start, workout end, wake time, and bedtime drive the schedule.

    FAQs

    1) Does this calculator prescribe supplement doses?

    No. It organizes timing. Dose boxes are optional record fields. Dose decisions should follow your product label or a clinician’s advice.

    2) Why are vitamin D and omega-3 often placed with the largest meal?

    They are commonly scheduled with a substantial meal to improve tolerance and support consistent intake, especially when fat-containing foods are present.

    3) Why can caffeine move earlier than my workout?

    The tool protects sleep first. If your bedtime is relatively early or sensitivity is high, it shifts stimulant timing to reduce late-day interference.

    4) Why is magnesium usually placed near bedtime?

    Evening timing is practical, easy to remember, and usually keeps magnesium away from iron and daytime stimulants.

    5) Why does iron receive extra caution notes?

    Iron timing can be disrupted by coffee, tea, large mixed meals, and other minerals. That makes spacing and monitoring more important.

    6) Can I use this on rest days?

    Yes. If no workout is provided, the tool falls back to meal-based or routine-based anchors so you still get a usable daily plan.

    7) Is the schedule medically personalized?

    No. It is a structured timing guide. It does not diagnose deficiencies, check drug interactions, or replace medical care.

    8) What should I do if the schedule feels unrealistic?

    Prioritize consistency. Keep the same anchor daily, simplify the stack, and discuss special conditions like pregnancy, anemia, reflux, or medications with your clinician.

    Important: This nutrition tool is educational. It does not replace diagnosis, medication guidance, or individualized medical advice.
