You can plan your training, your protein and your water intake, and still leave the most important eight hours of the day entirely to chance. Here's what happens in those hours, and what we built to support them.

Sleep is a night-time nutrition formula designed to support the two things that make rest count: getting to sleep, and what your body does once you're there. It combines four ingredients studied for their role in sleep onset and quality (glycine, L-theanine, magnesium and taurine) with collagen peptides and tart cherry to support the overnight repair window. It contains no added melatonin, is made in-house in Australia, and it's the first dedicated sleep product True Protein has released.
Most recovery routines stop at the front door of the biggest recovery window of the day. Sleep is built for that window.
Because it's the one part of a health routine people are most likely to compromise, and least likely to do anything deliberate about.
Training, protein intake and hydration all get planned. Sleep gets whatever is left at the end of the day, and the numbers show it. Inadequate sleep, whether that's insufficient duration or poor quality, affects up to 45% of Australian adults, according to the 2016 Sleep Health Foundation national survey published in Sleep Health. Two in three Australian adults report at least one sleep problem, and almost half report at least two, and Deloitte Access Economics has estimated the combined direct and indirect cost of sleep disorders to the Australian economy at $51 billion in 2019–20.
That gap matters more than most people realise, because sleep isn't downtime. It's when the work gets done.
Overnight, your body shifts into a repair state. Growth hormone release peaks, muscle protein synthesis, the process of building and repairing muscle tissue, continues, connective tissue like skin, tendons and cartilage is remodelled, and the nervous system consolidates the day's learning and resets its stress response.
Cut those hours short and the work doesn't get finished. Research published in The Journal of Physiology found that healthy young men who spent five nights with only four hours in bed had lower rates of myofibrillar protein synthesis, the specific process that maintains muscle tissue. In plain English: short sleep appears to slow the body's repair work.
This is the honest version of the sleep argument. It isn't that one bad night undoes everything. It's that sleep is a compounding input, and most people are quietly running a deficit.
No, and this is worth being clear about. A formula supports a good night's sleep; it doesn't replace one.
Consistent bed and wake times, morning light, limiting caffeine after early afternoon, and getting screens out of the last hour of the day do more for sleep than any supplement will. In the same national survey, 26% of Australian adults reported using the internet most or every night just before bed alongside frequent sleep difficulties or daytime impairment.
Sleep is designed to work alongside those habits. Think of it as the nutritional layer of a wind-down routine, not a substitute for having one.
Sleep is an easy-to-mix, low-calorie night-time drink in a 10g serve, available in Tropical. Each 300g pouch contains 30 serves.
The formula is built on three pillars, each doing a different job.
| Pillar | Ingredients per serve | What it's there for |
| Advanced Sleep Matrix | 3g glycine, 200mg L-theanine, 1.84g magnesium citrate, 500mg taurine | Supporting the transition into sleep, settling the mind and easing into deeper sleep stages |
| Collagen & connective tissue | 3g collagen hydrolysate (Solugel® Ultra BP), vitamin C, zinc, plant-based silica (Bloosil®) | Supporting the overnight repair of skin, joints, tendons and connective tissue |
| Antioxidant support | 480mg tart cherry powder, vitamin C, zinc | Supporting the body against the oxidative stress of a demanding day |
No added melatonin. Made in-house in Australia. Not suitable for vegans, due to the collagen peptides.
By addressing the two most common barriers to sleep onset: a nervous system that's still switched on, and a body that hasn't settled.
Glycine is an amino acid, a building block of protein, that also acts as an inhibitory neurotransmitter, meaning it helps quiet nerve signalling rather than excite it. Research published in Sleep and Biological Rhythms found that 3g of glycine taken before bed improved subjective sleep quality and sleep efficacy, and shortened the time taken both to fall asleep and to reach slow-wave sleep, without altering sleep architecture, that last term meaning the natural pattern and sequence of sleep stages. The same trial reported that glycine reduced daytime sleepiness and improved performance on memory recognition tasks. Sleep provides that studied 3g dose.
L-theanine is an amino acid found naturally in green tea, associated with a calm-but-alert state rather than sedation. In a randomised, placebo-controlled crossover trial published in Nutrients, 200mg of L-theanine per day for four weeks reduced Pittsburgh Sleep Quality Index scores in healthy adults, with the subscale scores for sleep latency, sleep disturbance and use of sleep medication all improving compared with placebo. Sleep provides 200mg, the dose used in that research.
Magnesium is involved in hundreds of enzymatic reactions in the body, including muscle contraction, nerve signalling and the regulation of the sleep-wake cycle. It's also a nutrient plenty of Australians miss: ABS analysis released in March 2026 found 31% of Australians did not meet their magnesium requirements from diet. Sleep uses magnesium citrate, a form chosen for absorption and digestive tolerance.
Taurine is an amino acid that supports the regulation of the nervous system and the body's stress response, the "settling" half of winding down.
Because the overnight window is when connective tissue repair happens, and collagen is the raw material for it.
Collagen is the structural protein that makes up skin, tendons, ligaments and cartilage. Hydrolysed collagen, collagen broken down into smaller peptides, is more readily absorbed than intact collagen. Sleep provides 3g of Solugel® Ultra BP collagen hydrolysate per serve, alongside vitamin C, which the body requires for normal collagen formation, and zinc and plant-based silica, which support connective tissue and skin structure.
Pairing collagen with vitamin C isn't a marketing flourish. Vitamin C is a necessary cofactor in collagen synthesis, which is why the two belong in the same serve.
It's also worth noting that glycine, the sleep ingredient above, is one of the most abundant amino acids in collagen. In a formula like this, it's doing two jobs at once.
Tart cherry is included for antioxidant support at the end of a demanding day.
Tart Montmorency cherries are rich in anthocyanins, plant compounds that give the fruit its deep colour and have been studied for their antioxidant and anti-inflammatory properties. In a randomised, double-blind, placebo-controlled crossover trial published in the European Journal of Nutrition, seven days of tart cherry juice concentrate produced significant increases in time in bed, total sleep time and sleep efficiency compared with placebo.
Sleep provides 480mg of tart cherry powder per serve.
Two products, two jobs. The simplest way to think about it: Magnesium+ is a daily recovery blend you can take any time of day. Sleep is a dedicated night-time formula.
| Magnesium+ | Sleep | |
| Job | Daily recovery and stress resilience | Night-time sleep support and overnight repair |
| When | Any time of day, morning, post-training or midday | Evening, as part of a wind-down routine |
| Serve | 5g | 10g |
| Flavour | Natural, Blood orange, Lemon Burst, Pineapple | Natural, Tropical, Mixed Berry |
| Key actives | Magnesium citrate, glutamine, zinc, vitamin B6 | Glycine, L-theanine, magnesium citrate, taurine, collagen peptides, tart cherry |
| Best for | Muscle repair, cramping, a daily magnesium top-up | Falling asleep, sleeping deeply, waking clear-headed |
You can take both, but space them out rather than stacking them in the same serve. Sleep already contains a meaningful magnesium dose, so the cleanest routine is Magnesium+ in the morning or midday and Sleep in the evening.
Sleep is designed for anyone who wants to get more out of the hours they're already spending in bed, whether that's someone who lies awake with a busy mind, someone who wakes through the night, or someone whose sleep has quietly become the weakest link in an otherwise solid routine.
It's not suitable for vegans, due to the collagen peptides. If you're pregnant, breastfeeding, taking medication or managing a health condition, speak with your doctor before starting any new supplement. Persistent sleep problems are worth raising with a GP, insomnia and sleep apnoea are common, treatable, and not something a supplement is intended to address.
