Supplements in diet plans: vitamins and compounded formulas

Fitney Team September 25, 2026 2 min read
Supplements in diet plans: vitamins and compounded formulas

Vitamin D, omega-3, creatine, magnesium, a compounded formula for gut health. Supplements are part of many plans, but they usually end up in the wrong place: a notes field the client never reads, a chat message that gets buried, or a paper prescription kept apart from the meal plan.

In Fitney, supplements are a prescription of their own for each client, which you link to the meal plan.

What you enter for each item

Each supplement or formula has simple fields:

  • Name or composition: “Vitamin D3 10,000 IU” or the full compounded formula;
  • Dose: 1 capsule, 5 g, 20 drops;
  • When to take it: fasting, with lunch, before bed;
  • Duration: 60 days, ongoing. If left blank, the prescription’s or the meal plan’s period applies;
  • Notes: take with a source of fat, don’t mix with coffee, and so on.

The prescription can have a name and a period, and you end it when the protocol is over.

With or without a meal plan

Supplements don’t depend on a meal plan. You can prescribe supplements only, for example for a client in follow-up who hasn’t received a meal plan yet.

When there is a meal plan, you link the prescription to it. When you copy or renew the same client’s meal plan, the link is kept.

Kept out of the macro count, on purpose

The prescription is separate from meals, and that’s intentional. Vitamins, minerals and compounded formulas have no meaningful calories and shouldn’t mess up the macro totals or the shopping list.

Supplements that do have calories (whey, maltodextrin, mass gainers) can still go in as a food inside a meal, where they count toward the target.

In the client’s app and PDF

The linked prescription shows up in the app, alongside the meal plan, and active prescriptions without a meal plan are visible to the client too. The client doesn’t have to dig up the prescription or an old chat to remember the dose.

In the meal plan PDF, the linked supplements get their own section. The prescription can also be exported on its own as a PDF.

Why organize supplements

  • Adherence: clients follow what’s clear, with dose and timing.
  • Fewer questions over chat: the answer is already in the app.
  • Records: supplements are documented with period and history, which helps at review and follow-up.

Conclusion

With dose, timing and duration in a prescription of their own, linked to the meal plan, supplements move out of the notes field and become part of the follow-up, in the app and in the PDF.

Frequently asked questions

Do supplements count toward the diet's calories? +

No. The supplement prescription is kept separate from meals, designed for vitamins, minerals and compounded formulas that don't belong in the macro count. Supplements with meaningful calories, like whey protein or mass gainers, can still be added as a food inside a meal.

Do I need a meal plan to prescribe supplements? +

No. The supplement prescription belongs to the client and can exist without a meal plan. When there is one, you link the prescription to it and both show up together in the app and in the PDF.

Can the client see the supplements in the app? +

Yes. The linked prescription shows up alongside the meal plan in the client's app, and active prescriptions without a meal plan are visible too. Dose, timing and duration are also printed in the PDF.
