OMG Magnesium Pain Rescue Set - Spray & Cream
Couldn't load pickup availability
Cream for the daytime. Spray for the night.
Two products, two times of day.
The cream is for the daytime ache. The chronic stiffness, the calves that cramp before a run, the post-shift recovery, the back that needs a daily ritual.
The spray is for the night. The bedtime aches, the restless legs, the body that needs to settle before sleep.
Most customers who try one find they need both. We bundled them so you save £8 against the combined RRP, with free UK delivery included.
What's in the set
250ml OMG Magnesium Cream. 15 botanical actives, 15% magnesium, capsicum for natural pain relief, pinene as a natural anti-inflammatory.
175ml OMG Magnesium Sensitive Spray. Botanical, sensitive-skin formula. Magnesium chloride, magnesium sulphate, lavender, arnica, rosehip, Kalahari melon seed oil.
Both products in aluminium packaging. Refills available for the spray.
The cream: for the day
For the chronic ache you've stopped mentioning to your GP. For the calves that always cramp at mile 18. For the post-shift evenings when you can't get up off the sofa. For the knees, hips, and shoulders that need a daily ritual, not another pill.
15 actives, working together. Capsicum delivers natural pain relief. Pinene works as a natural anti-inflammatory. Arnica and rosemary ease muscle aches and joint stiffness. Magnesium at 15% absorbs through the skin to support muscle recovery. Aloe vera, rosehip, melon seed oil, shea and cocoa butter moisturise without clogging pores. Lavender and camphor soothe the body and calm the mind.
No chalky residue. No industrial menthol smell. Absorbs cleanly so it doesn't get on jewellery, sheets, or training kit.
Used by professional sports therapists
"When I was working in professional rugby league at Leeds Rhinos, we would often use magnesium cream five minutes before the boys would run out onto the pitch. The athletes swore by it to prevent cramping."
- Steve Bannister. Performance Coach and Sports Therapist.
The spray: for the night
For bedtime aches and stiffness. Knees, back, joints, arthritis-related discomfort. For the restless legs that won't let you settle. For the long day that needs to release before sleep.
Lightweight formula, absorbs in about 30 seconds, no greasy residue. Sensitive-skin friendly. Used as part of an evening wind-down routine, applied directly to the area that aches.
Key ingredients:
- Magnesium chloride and magnesium sulphate: supports muscle function.
- Lavender: helps promote sleep.
- Arnica: can ease joint and muscle pain.
- Rosehip: can reduce inflammation.
- Kalahari melon seed oil: calms sensitive skin.
How to use the system
Cream during the day. Rub into the muscle nearest the pain. Use it before exercise to reduce the risk of cramping. Use it after a long shift, after the gym, or during the chronic ache that arrives mid-afternoon. Up to three applications a day.
Spray before bed. Spray onto a thin part of the skin (back of the knee, neck, or any aching muscle, not face or eyes). It dries in about 30 seconds. You can rub it in with your hands if you prefer. For sleep, 2 to 3 sprays is the usual amount. You should notice the difference within about a minute.
A note on jewellery
Magnesium spray, especially combined with natural oils or perspiration, can occasionally react with silver and cause it to tarnish. It's harmless and reverses with a silver cleaning cloth, but to avoid it apply the spray to clean, dry skin and let it absorb fully before putting on jewellery.

Frequently Asked Questions
How quickly does the spray work?
OMG absorbs through the skin in around 30 seconds. Many customers notice a difference within minutes. Unlike tablets, which can take 30 minutes or more to pass through the digestive system, a spray delivers magnesium directly through the skin into the bloodstream.
Will it irritate or sting my skin?
OMG is specifically formulated for sensitive skin. Our founder Hazel has hypersensitive skin and would not have launched the product if she couldn't use it herself. The formula includes Kalahari melon seed oil, which calms the skin and prevents the stinging or itching that many other magnesium sprays cause.
Can magnesium spray help with perimenopause and sleep?
During perimenopause, declining oestrogen levels affect how the body absorbs and uses magnesium. Lower magnesium can disrupt melatonin production and make it harder for the nervous system to switch off at night. Applying magnesium through the skin before bed may help the body relax and prepare for sleep. Many of our customers in perimenopause report improved sleep quality. We always recommend speaking with your GP alongside any supplement.
Learn moreWhat is the Magnesium Recovery Cream for?
The cream is designed for targeted muscle relief. Apply it before exercise to help reduce the risk of cramping, or after exercise to support faster recovery. It is also used by customers for general muscle aches, joint stiffness, and chronic pain. It is used by sports therapists in professional clinics alongside H2K's magnesium spray.
How is the cream different from the spray?
The spray absorbs quickly and is ideal for sleep, relaxation, and general magnesium delivery through thin-skinned areas like wrists and knees. The cream is thicker, stays on the skin longer, and is designed for targeted application on specific muscles or joints. It also contains capsicum for pain relief and pinene as a natural anti-inflammatory, which the spray does not. Many customers use both: the spray before bed and the cream before or after exercise.
What are capsicum and pinene?
Capsicum is derived from chilli peppers and is widely used for its natural pain-relieving properties. It works by creating a gentle warming sensation that helps increase blood flow to the area. Pinene is a compound found in pine resin and is a natural anti-inflammatory. Together with magnesium, they provide targeted support for muscle and joint discomfort.
