One sheep, two sheep, three sheep, four sheep…. yep, still can’t fall asleep. Let’s be real – does that ever work for anyone? If you sometimes struggle to fall asleep, Persona’s 4 supplement Sleep Formula is dietitian-approved and can help you say bye-bye to the baa-baas. Read on to learn about all its benefits. 


This adaptogenic super root helps combat one of the most common reasons we struggle with sleep: stress. When your body is under stress, it reacts by producing cortisol – your main stress hormone. If left unchecked, cortisol can lead to fatigue and impact multiple functions in your body, including sleep. Ashwagandha or Withania somnifera has been traditionally used to help your body cope with stress. How? Researchers think it works by prolonging your body’s resilience and delaying exhaustion from the stressor, giving you more time to address your stress and helping you get that much needed shut-eye.1 Put simply: it acts as a speed bump to stress.       

Beauty Sleep 

The most underrated part of your skin care routine? Great sleeping habits. The Sleep Formula includes Beauty Sleep, which is your overnight glam squad. Its beautifying ingredients support healthy hair skin & nails and the added L-theanine promotes a restful sleep.* The amino acid L-theanine is thought to work by increasing GABA, serotonin and dopamine – naturally occurring chemicals your body makes that are involved in your sleep-wake cycle and helps support your overall mood.2 And to ensure you’re getting your beauty rest (literally), fish collagen, sodium hyaluronate and horsetail extract are all ingredients that your skin loves. They promote healthy, hydrated skin.*  


No surprises here. Goodnight is exactly what you would expect: it supports a good night’s rest.* But it’s especially helpful if your mind tends to get a little busy at night. Key ingredients found in this supplement include: passion flower, lavender and valerian root extract. Passion flower and lavender promote relaxation and calming after a long day to help your body wind down and rest.* Valerian root also helps support a calm mind. It’s thought to work by increasing  circulating levels of GABA, a chemical found in your body known to calm your central nervous system and promote a restful sleep.3 

Herbal Rest 

Herbal rest helps your body relax, physically and mentally.* It contains magnesium, L-theanine and hops flower. Magnesium is a vital mineral involved in over 300 processes in your body, including muscle function. The magnesium in Herbal Rest targets tension to help support relaxed muscles.* L-theanine plays a role in your sleep-wake cycle, while promoting a healthy mood.* Hops flower extract works in a similar way to promote calming and relaxation by reducing the activity of your central nervous system.*4  

How they work together

Ashwagandha, Beauty Sleep, Goodnight and Herbal Rest work great by themselves but when you combine them all you have a sleep support dream team. Ashwagandha helps ease the effects of stress*, Good Night and Herbal Rest help to calm and relax the mind and body* and Beauty Sleep supports healthy hair, skin and nails* while easing you into relaxation mode.* With these four supplements in the Sleep Formula you can forget about counting sheep and go to sleep with ease*.
