Sleep vs Magnesium+: Which One Do You Actually Need?

Magnesium+ and Sleep are both magnesium-based, but they do two different jobs. Magnesium+ is a daily recovery blend you can take at any time of day to support muscle function and stress resilience. Sleep is a dedicated night-time formula built around glycine, magnesium and L-theanine to help you wind down, settle faster and recover overnight.

If you're deciding between them, or wondering whether you can take both, here's how they differ, and how to fit them into your routine.

What is Magnesium+, and what does it do?

Magnesium+ is an everyday magnesium supplement designed to be taken whenever it suits you. Each 5g serve delivers 2.8g of magnesium citrate, a highly soluble form of magnesium that mixes clearly and is well absorbed, alongside glutamine, zinc and vitamin B6.

Magnesium is a cofactor in more than 300 enzyme systems in the body, including those governing muscle contraction, nerve transmission, protein synthesis and energy production. In plain English: it's involved in almost everything your body does to repair itself and keep functioning normally, which is why running low tends to show up as fatigue, muscle cramping and poor recovery rather than one specific symptom.

The supporting ingredients each have a defined role:

• Glutamine — the most abundant amino acid in the body, used heavily during periods of physical stress and training load.
• Zinc — an essential mineral involved in immune function and protein synthesis.
• Vitamin B6 — required for protein and amino acid metabolism, and for magnesium's transport into cells.

Magnesium+ comes in Natural, Lemon Burst, Pineapple & Blood Orange, in a 250g bag (50 serves) and a 5g single-serve sachet.

What is Sleep, and what does it do?

Sleep is our first dedicated night-time formula. It isn't a magnesium supplement with a bedtime label on it, it's a different formula, built around ingredients with evidence behind them specifically for the hours between lights-out and waking up.

Each 10g serve (natural) contains:

• Glycine (3g) — an amino acid that acts as an inhibitory neurotransmitter, meaning it dampens rather than stimulates nerve signalling. In a polysomnography study (sleep measured in a lab rather than self-reported), 3g of glycine before bed shortened the time taken to fall asleep and to reach slow-wave sleep, without altering normal sleep architecture.
• Collagen hydrolysate (3g) — collagen peptides are naturally rich in glycine. A trial in physically active males with sleep complaints found that collagen peptides taken before bed reduced sleep fragmentation and improved next-day cognitive performance.
• Magnesium citrate (2.6g) — a meaningful dose, supporting normal muscle and nervous system function overnight. 
• L-theanine (200mg) — an amino acid found naturally in green tea. A 2025 systematic review of 13 trials concluded that 200–450mg per day supports healthy sleep in adults, with the most consistent benefits seen in sleep quality, sleep latency and how refreshed people felt on waking.
• Taurine (500mg) — an amino acid involved in nervous system regulation.
• Tart cherry powder (480mg) — a natural food source of melatonin and anthocyanins, the pigments that give the fruit its colour.
• Vitamin C, zinc and Bloosil® plant-based silicon — supporting collagen synthesis and normal connective tissue formation.

Sleep comes in Natural, Mixed Berry & Tropical, in a 300g satchel (30 serves).

What's the actual difference between Sleep and Magnesium+?

Can I take Sleep and Magnesium+ together?

Yes, but space them out rather than taking them at the same time.

Sleep already contains a meaningful dose of magnesium, so there's no need to double up in the evening. If you'd like both in your routine, take Magnesium+ in the morning or the middle of the day, and keep Sleep for the evening.

When does Magnesium+ make the most sense?

Magnesium+ is particularly useful after a morning training session where you've sweated a lot, or on days with a heavy training load. Magnesium is lost through sweat, and requirements sit higher for people training regularly than for the general population.

When should I take Sleep?

Around 30 to 60 minutes before bed. The glycine research used a similar window, the studies above gave participants glycine roughly an hour before bedtime.

Do I need both, or will one do the job?

Most people don't need both. Start with the one that matches the problem you're actually trying to solve.

Choose Magnesium+ if:

• You want a straightforward daily magnesium supplement
• You're training regularly and want support for muscle function and recovery
• You'd rather take it in the morning or with lunch than at night

Choose Sleep if:

• Winding down is the harder part of your day
• You wake through the night or don't feel recovered in the morning
• You want overnight sleep support

Consider both if:

• You train hard in the morning and struggle to switch off at night, in which case, Magnesium+ early, Sleep late.
