What is Sleep+ and who is it for?
Sleep+ is a capsule-based sleep and relaxation supplement from Switch Nutrition, combining magnesium glycinate with Ashwagandha KSM-66®, hops flower extract, zinc, and activated B6. It’s formulated for adults who want nutritional support for sleep quality and evening wind-down as part of a healthy lifestyle. The formula is ARTG-listed (AUST L 474230), vegan-friendly, and free from gluten, dairy, and artificial additives.
This makes sense if you’re looking for a non-sedative, nutrient-based approach to sleep support rather than pharmaceutical options. The combination of magnesium, a traditional calming herb, and activated B vitamins addresses several nutritional factors involved in normal sleep physiology, without the grogginess some people associate with melatonin or antihistamine-based products.
Fairfield Nutrition Thoughts
Sleep is one of the most common areas where people seek supplement support, and it’s also one where the quality of formulation varies enormously. Many sleep products lean heavily on melatonin or sedating antihistamines, which can work short-term but don’t address the nutritional factors that underpin normal sleep architecture. Sleep+ takes a different approach, combining magnesium glycinate with two well-researched herbal and nutritional ingredients to support the physiological conditions that allow sleep to happen naturally.
The evidence for magnesium and sleep is solid at a mechanistic level, and KSM-66® ashwagandha has a reasonable body of human trial data supporting its role in stress and sleep quality. Hops flower has a long traditional use history for nervous system calming, and the inclusion of pyridoxal-5-phosphate (the active form of B6) is a thoughtful addition given B6’s role in neurotransmitter synthesis pathways. The ARTG listing and clean formulation profile make this a straightforward option for people wanting nutritional support for sleep without unnecessary additives.
Why This Formulation / How It Works
Most magnesium supplements use oxide or citrate forms, which are cheaper but can cause digestive discomfort at higher doses. Sleep+ uses magnesium glycinate, where magnesium is bound to the amino acid glycine. This form is generally better tolerated and glycine itself has a role in the nervous system as an inhibitory neurotransmitter. The ashwagandha used is KSM-66®, a patented root extract standardised to withanolide content, which is the form used in most of the published human research on ashwagandha and stress. The B6 is provided as pyridoxal-5-phosphate, the already-active form that doesn’t require conversion in the liver before the body can use it.
The formula is ARTG-listed (AUST L 474230), meaning it has been assessed by the TGA for safety and quality. It’s free from gluten, dairy, animal products, and artificial additives, which makes it accessible for most dietary preferences.
Magnesium’s Role in Nervous System and Muscle Physiology
Magnesium is involved in over 300 enzymatic processes in the body, including those that regulate nerve signalling and muscle relaxation. It acts as a natural calcium antagonist in muscle cells, meaning it plays a role in the normal cycle of muscle contraction and relaxation. In the nervous system, magnesium is involved in the regulation of NMDA receptors, which are part of the excitatory signalling pathway. Many Australians have suboptimal dietary magnesium intake, making supplementation a reasonable consideration for those looking to support sleep and relaxation.
Ashwagandha KSM-66® and the Stress-Sleep Connection
Ashwagandha (Withania somnifera) is an adaptogenic herb with a long history of use in Ayurvedic medicine for nervous system wellness. The active constituents, withanolides, are concentrated in the root and are the focus of most modern research. KSM-66® is standardised to a minimum withanolide content and is the form used in human studies examining ashwagandha’s role in stress perception and sleep quality. Each daily dose of Sleep+ provides 300 mg of KSM-66® extract, equivalent to 3.75 g of dry root.
B6 and Neurotransmitter Synthesis Pathways
Pyridoxal-5-phosphate is the active coenzyme form of vitamin B6 and serves as a cofactor in the synthesis of several neurotransmitters including serotonin, GABA, and dopamine. These neurotransmitters are involved in mood regulation and the normal sleep-wake cycle. Using the active P5P form means the body can utilise it directly without requiring liver conversion, which is relevant for people who have variations in B6 metabolism.
When to Consider This
This supplement provides nutritional support for sleep wellness. It makes sense if you’re:
- In a period of elevated stress or life demands where evening wind-down feels more difficult than usual.
- Looking for a non-sedative, nutrient-based approach to sleep support rather than pharmaceutical options.
- Someone who suspects suboptimal magnesium intake may be contributing to muscle tension or restless evenings.
- Perimenopausal or in a life stage where sleep quality has shifted and you want nutritional support alongside lifestyle changes.
Supplement strategy: Sleep+ is typically introduced as a standalone sleep support supplement or alongside foundational magnesium if additional daytime magnesium intake is also a goal. Many people use it consistently for several months while also addressing sleep hygiene and stress management practices.
⚠️ Not suitable for: Children under 18, pregnancy, breastfeeding. Not for use if tamper seal is broken. If symptoms persist, consult your healthcare professional.
How to Use
Take 4 capsules with water 30 to 60 minutes before bed. Each daily dose of 4 capsules provides 320 mg elemental magnesium, 300 mg KSM-66® ashwagandha extract, 300 mg hops flower extract, 12 mg elemental zinc, 10 mg vitamin B6 (as P5P), and 80 mg vitamin C.
The 30 to 60 minute window before bed allows the magnesium and herbal ingredients time to be absorbed before you’re aiming to sleep. Taking with a small amount of food may be preferable if you find capsules on an empty stomach uncomfortable, though the glycinate form of magnesium is generally well tolerated.

Common Questions
Why does this use magnesium glycinate instead of other forms?
Magnesium glycinate is generally better tolerated than oxide or citrate forms, which can cause loose stools at higher doses. The glycine component also has its own role in the nervous system as an inhibitory neurotransmitter, making it a logical pairing for an evening formula.
What is KSM-66® and why does it matter?
KSM-66® is a patented, standardised ashwagandha root extract with a defined withanolide content. It’s the form used in most published human research on ashwagandha, which means the research findings are more directly applicable to what’s in the capsule than with generic ashwagandha extracts.
Can I take this every night long-term?
The ingredients in Sleep+ are formulated for ongoing daily use as part of a healthy lifestyle. Magnesium, zinc, and B vitamins are nutrients the body uses continuously, and ashwagandha and hops have long traditional use histories. If you have specific health concerns or are taking medications, check with your healthcare professional first.
Will this make me feel groggy the next morning?
Sleep+ doesn’t contain melatonin or sedating antihistamines, which are the ingredients most commonly associated with morning grogginess. The formula works through nutritional and herbal pathways rather than sedation, which is why some people find it doesn’t have the heavy next-morning feeling of other sleep products. Individual responses vary.
