Read the science
  1. Days 1–5

    Menstrual

    Your period means your body loses iron with each bleed, and energy often dips. Iron contributes to the normal formation of red blood cells and haemoglobin, and magnesium contributes to the reduction of tiredness and fatigue.

    Iron · Magnesium

  2. Days 6–13

    Follicular

    Oestrogen starts to rise and energy builds as your body prepares a new egg. Folate has a role in the process of cell division, and vitamin D contributes to the maintenance of normal muscle function, ready for when you feel like moving more.

    Folate · Vitamin D

  3. Days 14–16

    Ovulation

    Oestrogen peaks and an egg is released. Zinc contributes to normal fertility and reproduction, and to the normal function of the immune system.

  4. Days 17–28

    Luteal

    Progesterone rises, then both hormones fall before your next period, and many women feel more tired. Vitamin B6 contributes to the regulation of hormonal activity and the reduction of tiredness and fatigue. Researchers suggest creatine may be especially relevant in this phase, as hormone shifts change how the body uses energy.

Days are based on a typical 28-day cycle; every cycle is different. Creatine research: Smith-Ryan et al., Nutrients, 2021.

I’ve been trying these cycle support bars for the past week and have really enjoyed them so far. The flavours are great, with raspberry being my favourite. They taste good and are an easy snack to include in my day.

It’s still early days to comment on the full benefits, but I already feel a little less spiky throughout the week, which is encouraging. I’m ordering more and look forward to seeing how they support me over time.

I recently purchased these bars and they taste delicious (especially salted caramel). They are incredibly filling, far more so than other bars on the high-street.

Best bars ever! Make you feel so light and healthy - compared to protein bars which make me feel heavy and full. 10000% would recommend, will be buying again!!

Excellent bars! I love these little bites of goodness. Great flavours - my favourite is the lemon blueberry! My new go to snack when I’m on the go.
