10% to 30% of Western Adults are Magnesium Deficient. Symptoms include tiredness, muscle cramps, poor sleep, headaches & irritability.

This is an orange-flavoured soluble tablet delivering 200mg of elemental magnesium (Mg) per tablet from a blend of magnesium citrate and magnesium oxide. Drop one tablet into a glass of water, and it dissolves into a mild orange drink sweetened with stevia. 20 tablets is a three-week supply at one a day.

Why Citrate & Oxide Together

• Mg citrate is one of the best-studied bioavailable forms (Lindberg et al., 2017, BMC Nutrition), significantly better absorbed than oxide and well tolerated at standard doses.
• Mg oxide is the cheapest form with a low bioavailability of roughly four per cent (Firoz and Graber, 2001), but it has a mild osmotic effect that helps bowel comfort in some people.

Higher Nature combines the two: citrate for the absorbed fraction that raises magnesium status, and a small oxide fraction that adds bowel regularity without compromising the overall absorption of the tablet. It is a practical, middle-ground blend aimed at general daily use rather than a high-absorption chelated approach.

Magnesium Deficiency

The EU Nutrient Reference Value (amount you take) for magnesium is 375mg per day.

Subclinical deficiency affects an estimated ten to thirty per cent of the Western population. This means you have effects of being low in this nutrient but blood tests don't come back as deficient.

Effervescent formats are popular because the supplement that actually gets taken is the one that works, and for many people, a pre-measured tablet that dissolves into a pleasant drink is easier to stick with than swallowing a capsule every day.

As a nutrient, it helps with the reduction of tiredness and fatigue, improves energy-making metabolism, relaxes muscle tension,reduces stress and improves sleep while balancing the nervous system and strengthening normal bones.

 These are EFSA-approved claims (not just marketing).

Higher Nature Effervescent Energy & Muscle Function

This mineral helps with muscle relaxation and a reduction of tiredness and fatigue.

The effervescent format suits anyone who wants the convenience of a portable magnesium: commuters, travellers, gym-goers, and people who do not like swallowing capsules. At 200mg elemental Mg per tablet, one a day covers more than half the EU NRV, with the rest coming from food. It is a sensible general daily magnesium rather than a specialised sleep or cognitive formula.

How Magnesium Oxide works

It works by delivering a high amount of elemental magnesium, but with low absorption.

Gut effect

Draws water into the bowel, which softens stool and stimulates movement. It's good for a clearing out:  for wind, IBS and constipation.

Only a small portion is absorbed into the body, so most stays in the gut. For this reason, it has a very limited role in muscle relaxation (and recovery), sleep, stress, heart, etc. As absorption is low, it’s not effective for raising magnesium levels in tissues.

Best used as a laxative, not for correcting magnesium deficiency or calming the system.

How Magnesium Citrate works

 This is the "active" type of Magnesium in these fizzy tablets. It works through a few key pathways rather than doing just one thing.

 Absorption and availability

Magnesium citrate is bound to citric acid, which keeps it soluble in the gut. That means it’s absorbed more efficiently than heavier forms like oxide, so you actually raise your magnesium levels rather than just passing it through.

Muscle and nerve function

Magnesium controls how calcium moves in and out of muscle cells. Calcium triggers contraction, magnesium allows relaxation. When levels are low, muscles stay tight and reactive, and when you top it up, things loosen, cramps ease, and tension drops.

Energy production

Magnesium is needed to produce ATP, the energy source your cells run on. It acts as a cofactor in hundreds of reactions linked to energy, so improving levels can help reduce fatigue and that run-down feeling.

Nervous system calming

Magnesium increases GABA activity, your brain’s main calming pathway, which helps take the edge off feeling wired or stressed.

That said, citrate is not the most calming form. If sleep or anxiety is the main issue, magnesium bisglycinate or glycinate are better choices, as they have a more direct calming effect on the nervous system.

Electrolyte balance

Magnesium helps regulate electrolytes like calcium and potassium, keeping muscle contractions, nerve signals, and hydration in balance.

Who is Higher Nature Magnesium for

• People who dislike swallowing capsules.
• Travellers and commuters who want a portable Mg.
• Gym-goers wanting a pre- or post-workout Mg drink.
• Anyone who prefers a pleasant orange drink to a tablet.
• General daily users not looking for a specialised bisglycinate or threonate.

FAQs: Higher Nature Magnesium Effervescent

Which forms of magnesium are in the tablet?

A blend of Mg citrate (for absorption) and a smaller fraction of Mg oxide (for bowel comfort). The citrate is the main absorbed fraction.

How much elemental magnesium does each tablet provide?

200mg per tablet, which is 53% of the EU Nutrient Reference Value of 375mg per day.

How do I take Higher Nature Effervescent?

Drop one tablet into a glass of water (around 200ml). Wait for it to dissolve fully, stir briefly if needed, and drink.

What does it taste like?

Mild natural orange flavour, sweetened with stevia. No added sugar.

Is it suitable for vegans?

Yes. The formulation is plant-based and vegan-friendly.

Will it cause loose stools?

The oxide fraction can have a mild osmotic effect at higher doses. At one tablet a day most people tolerate it well. If your bowels loosen, take with food.

How is this different from Marine Magnesium?

Atlantic Marine is a capsule with 300mg elemental magnesium per capsule from marine-source Aquamin plus trace minerals; it is positioned for everyday use with a food-state philosophy. The Effervescent is a portable tablet with 200mg elemental from a citrate-oxide blend; it is positioned for on-the-go convenience. Choose a format preference and daily routine.

Is it safe in pregnancy?

It is commonly used in pregnancy for leg cramps. Check with your midwife or pharmacist before starting.
