About This Product.

Mega-Mag by TRACE is a magnesium supplement sourced from trace minerals. Magnesium is one of the most studied micronutrients in sports and general health: it functions as a cofactor in hundreds of enzymatic reactions, with particular relevance to muscle contraction and relaxation, nerve signalling, energy metabolism, and sleep regulation. Deficiency is common, especially in people under physical or psychological stress, those who train regularly, and individuals with diets low in leafy greens, nuts, and wholegrains.

This product sits within TRACE's performance pillar, making it a sensible option for athletes in heavy training blocks, people experiencing muscle cramps or tension, or anyone whose blood work has flagged low magnesium. It also suits those who struggle with sleep onset or restlessness at night, since magnesium is studied for its role in supporting the nervous system's shift into a more relaxed state.

Magnesium sourced from trace minerals typically refers to ionic forms drawn from mineral-dense water or brine, which may support absorption compared to some oxide forms. As with all magnesium supplements, individual response varies depending on baseline status and the form used. A blood test remains the most reliable way to confirm whether supplementation is warranted for you.

Frequently Asked.

How do I know if I need a magnesium supplement?

The most reliable way is a blood test. Common signs of low magnesium include muscle cramps, poor sleep, fatigue, and irritability, but these are non-specific. A clinician can interpret your levels in context and advise whether supplementation is appropriate.

Is this suitable for people who exercise regularly?

Magnesium losses increase with sweat and physical exertion, making regular exercisers a group who may benefit from supplementation. It is particularly relevant during heavy training blocks where muscle recovery and sleep quality are priorities.

Can I take this alongside other supplements?

Magnesium is generally well tolerated alongside most common supplements. However, it can interact with certain medications, including some antibiotics and diuretics, so check with a pharmacist or your GP if you are on prescription medicines.

What is the difference between magnesium from trace minerals and standard magnesium oxide?

Trace mineral-sourced magnesium typically provides ionic magnesium in forms that may be more readily absorbed than magnesium oxide, which has a relatively low bioavailability. Check the packaging for the specific form and concentration used in this product.

When is the best time of day to take it?

Many people take magnesium in the evening given its association with relaxation and sleep support, though timing can depend on personal preference and tolerance. Taking it with food reduces the chance of digestive discomfort.

Noticeably better sleep within a week

4 months ago

Started taking this before bed after my GP mentioned my magnesium was on the lower end. Within about a week I was falling asleep faster and waking up less during the night. Nothing dramatic, just a quiet, consistent improvement. Will keep buying.

Great addition to my training stack

5 months ago

I train 5 days a week and have always struggled with leg cramps, particularly in the evenings. Been taking this for about six weeks now and the cramping has pretty much gone. Take it after my last workout of the day. Price point is solid too — hard to argue with £15.99.

Does the job, but the bottle doesn't last as long as I'd like

5 months ago

Works well — sleep feels deeper and I've had fewer muscle twitches since I started. My one gripe is that the container size feels small for the price. Got through it in under three weeks taking the suggested amount. Would be better value in a larger format.

6 months ago

Swapped from a cheap oxide form I was buying on Amazon and the difference is noticeable. Less digestive upset and I actually feel like it's doing something now. Stays in my nightly routine.

Solid supplement, no fuss

7 months ago

Does what it says. I picked this up after a friend who's a physio recommended it during a heavy marathon training block. Muscle recovery feels quicker and I'm sleeping through more consistently. Understated product — doesn't need to shout about itself.

Good product, slightly medicinal taste

8 months ago

I mix mine with water before bed and the taste is a bit mineral-y and sharp — not unpleasant exactly, but it took some getting used to. On the actual performance side though, the tension I used to carry in my shoulders at night has eased a lot. Just wish it tasted a bit more neutral.
