The science

The science

Science.
In rhythm.

Every dose, explained. We chose each ingredient and amount for a reason, checked the whole day against UK limits, and printed all of it.

01 / The daily rhythmRise · Train · Rest
A day in your body, as a 24-hour dialSchematic 24-hour dial with midnight at the bottom and midday at the top. Cortisol rises sharply after waking and peaks within 45 minutes, then falls through the day. Core body temperature is lowest around 05:00 and highest in the late afternoon. The night, from 23:00 to 06:00, is shaded. Rise sits at 07:00, Train at 13:00 and Rest at 21:00.Night00:0006:0012:0018:0024 hoursIllustrative
CortisolCore body temperature

A day in
your body.

Hormones and temperature follow a roughly 24-hour cycle. That is why we built the day around three moments.

  • 07:00 / Cortisol

    Peaks 30 to 45 minutes after waking

  • 05:00 / Body temperature

    At its lowest around 05:00, highest in the late afternoon

Shaded sector: night, about 23:00 to 06:00. The coloured dots on the ring show when each sachet sits in the day. Each line is scaled to its own high and low.

Illustrative shapes based on published timings, not measured data.

Morning

07:00 · Rise

Stirred into your morning coffee, porridge or water. About Rise

Daytime

13:00 · Train

In the active middle of the day, or around your session. Creatine works by building up, so the habit matters more than the minute. About Train

Night

21:00 · Rest

Your night-time sachet, 30 to 60 minutes before bed. Magnesium contributes to normal psychological function and the normal functioning of the nervous system. About Rest

03 / The UK yearRise / Vitamin D

From October to March,
the sun is not enough.

Seasonal light changes.
A daily routine stays simple.

  • January: not enough from sunlight
  • February: not enough from sunlight
  • March: changes to enough sunlight in late March
  • April: most people make enough vitamin D from sunlight
  • May: most people make enough vitamin D from sunlight
  • June: most people make enough vitamin D from sunlight
  • July: most people make enough vitamin D from sunlight
  • August: most people make enough vitamin D from sunlight
  • September: most people make enough vitamin D from sunlight
  • October: not enough from sunlight
  • November: not enough from sunlight
  • December: not enough from sunlight

Rise · 25 µg vitamin D3 every day

Most people make enough vitamin D from sunlightNot enough from sunlight

March: the change comes in late March or early April. Source: NHS.

“Between October and early March we do not make enough vitamin D from sunlight.”

This explains the seasonal sunlight gap. It is not an NHS recommendation for CYRCA or for everyone to take 25 µg. The NHS advises considering 10 µg a day in autumn and winter, and not taking more than 100 µg a day. Rise contains a quarter of that maximum.

A loading phase. About 20 g a day fills stores in about 6 days.

Illustrative shape based on Hultman et al. (1996) and the ISSN position stand (2017).

“Ingesting smaller amounts of creatine monohydrate (e.g., 3–5 g/day) will increase muscle creatine stores”

What we can say on the pack

Creatine increases physical performance in successive bursts of short-term, high intensity exercise. The beneficial effect is obtained with a daily intake of 3 g of creatine and applies to adults performing high intensity exercise. Train contains 5 g.

The UK authorised claim, word for word.

06 / Our rulesWhat we leave out

Some things stay
off the label.

Ingredients we chose not to use, and why.

CBDRequires novel food authorisation.
CaffeineYou already have coffee. Rise goes into it.
SugarRise is unsweetened. Train and Rest use stevia.
Proprietary blendsThey hide amounts. We print every one.

How we talk about it

Claims we are allowed to make.

In the UK, supplements may only use health claims from the government register. We only use those, word for word. Where an ingredient has no authorised claim, such as collagen or glycine, we tell you why it is there and make no claim at all.

Quality at launch

  • Made by a manufacturer working to Good Manufacturing Practice.
  • Every batch tested by an independent laboratory for heavy metals and microbiology.
  • Certificates of analysis available on request.
  • Sachets sized for one serving, so nothing sits open for weeks.

These are our launch commitments and will be confirmed with our manufacturer.
