When and how should I take AVEA Magnesium Complex?

Take two capsules daily, ideally with food and a glass of water.Magnesium can be taken at any time of day, but many people prefer taking it in the evening, as magnesium plays an important role in supporting normal nervous system function and muscle relaxation.For best results, we recommend taking it consistently at the same time each day

Why does the form of magnesium matter?

Not all magnesium supplements are absorbed equally. The effectiveness of a magnesium supplement depends largely on the chemical form in which magnesium is delivered.Many conventional over-the-counter magnesium supplements rely on magnesium oxide, a cheap form of magnesium which is poorly absorbed by the body and thus ineffective.More advanced formulations instead use organic or chelated magnesium compounds, which are generally better tolerated and more easily absorbed.Different forms of magnesium can also support different functions and have different benefits. For example, some forms are commonly used to support relaxation and sleep, while others play a larger role in cellular energy metabolism or muscle function.For this reason, our Magnesium Complex uses three complementary, highly bioavailable forms of magnesium:Magnesium Bisglycinate to support nervous system balance and sleepMagnesium Citrate to support muscle relaxation and digestionMagnesium Malate to support cellular energy productionThis triple-blend approach allows the formula to support multiple biological pathways simultaneously.

Can I take magnesium during the day, or only at night?

Magnesium can be taken either during the day or in the evening.Some people prefer evening intake because magnesium helps regulate nervous system activity and muscle relaxation, which may support sleep quality. Others prefer taking it during the day to support energy metabolism and muscle recovery.Both approaches are effective, consistency is what matters most.

Will magnesium cause digestive discomfort?

High doses of certain forms, such as magnesium oxide or large amounts of citrate, may cause digestive discomfort.AVEA Magnesium Complex uses balanced amounts of highly bioavailable magnesium forms designed to maximise absorption while remaining gentle on the digestive system.

Who can benefit from magnesium supplementation?

Magnesium plays a role in more than 300 biochemical reactions in the body, including processes involved in nervous system regulation, muscle function, cellular energy production, and metabolic balance.However, modern diets often provide less magnesium than the body requires. Soil depletion, food processing, and increased physiological demands from stress, exercise, and poor sleep can all contribute to lower magnesium intake and higher magnesium utilisation.For this reason, magnesium supplementation may be particularly beneficial for individuals who experience:poor sleep or difficulty relaxingmuscle tension or slow physical recoveryfatigue or low daytime energyhigh stress levels or demanding lifestylesMaintaining adequate magnesium levels is increasingly recognised as an important foundation for sleep quality, physical recovery, and long-term metabolic health.

Can I combine Magnesium Complex with other AVEA supplements?

Yes. Magnesium plays a central role in energy production, nervous system regulation, and muscle function, which makes it a versatile complement to many longevity-focused nutrients.Depending on your goals, Magnesium Complex can be combined with other AVEA formulations to support specific areas of health:For sleep and nervous system balance: Take Magnesium Complex together with Sereniser approximately 30 - 60 minutes before bed. Magnesium Bisglycinate helps calm the nervous system, while Sereniser supports the biological pathways involved in healthy sleep cycles.For muscle recovery and joint comfort: After intense physical activity, Magnesium Complex can be paired with Mobiliser. Magnesium Citrate and Malate support normal muscle function and relaxation, complementing Mobiliser’s joint and connective tissue support.For cellular energy and vitality: In the morning, Magnesium Complex can be taken alongside NMN. Magnesium is required for ATP activation, meaning it helps your cells utilise the energy produced through NAD⁺ metabolism.For metabolic balance: Magnesium Complex can also complement Stabiliser, as magnesium contributes to normal glucose metabolism and insulin sensitivity, supporting metabolic health alongside Stabiliser’s targeted ingredients.

Are AVEA supplements safe?

All AVEA formulations are developed in collaboration with longevity researchers and manufactured in GMP-certified facilities in Switzerland and Europe.Every batch is tested in independent Swiss laboratories to verify purity, potency, and safety. Our formulas are free from unnecessary fillers and designed with clinically studied ingredients and bioavailable forms.

When will I start to notice the benefits?

Some individuals notice improvements in sleep quality, relaxation, or muscle tension within the first few weeks.However, as magnesium levels in the body gradually replenish, the full benefits typically develop over 1–3 months of consistent use.As with all nutritional supplements, individual responses may vary.

Magnesium Complex

Magnesium is THE longevity mineral powering over 300 reactions in your body, and most adults aren't getting enough of it. From nervous system regulation and muscle function, to cellular energy production and your body's stress response, magnesium is involved in nearly every process that determines how well you sleep, recover, and perform.

Modern diets, however, often provide insufficient magnesium due to soil depletion, food processing, and increased physiological demands from stress, exercise, and poor sleep.On top of that, a large number of over the counter supplements rely on cheap Magnesium Oxide, which is poorly absorbed by the body and therefore not effective.

AVEA’s Magnesium Complex provides 300 mg of elemental magnesium in a blend of 3 highly bioavailable, complementary magnesium forms to support key physiological processes involved in rest, recovery, and energy metabolism.

Its targeted formulation helps:

Calm the nervous system and promote better sleep: Helps regulate your body's stress response and supports deeper, more restorative sleep cycles.
Support healthy muscle function and recovery: Relieves tension and supports faster recovery after physical exertion.
Boost sustained cellular energy: Required for ATP production, the fundamental energy currency of every cell in your body.

Comprehensive support for sleep, recovery, and cellular energy

Magnesium plays a central role in regulating the nervous system, muscle relaxation, and cellular energy production. Yet many people do not reach optimal magnesium intake due to modern dietary patterns, stress, and increased physiological demand.

We designed AVEA’s Magnesium Complex to support the key biological pathways where magnesium plays the most important role: nervous system regulation, muscle recovery, energy metabolism, and digestive balance. We chose three highly bioavailable magnesium forms, each selected for how it's absorbed and where it works in the body.

Calm Nerves & Better Sleep Muscle Relaxation & Physical Recovery

Magnesium supports the nervous system and helps regulate neurotransmitters involved in relaxation and sleep. We chose to include Magnesium Bisglycinate for this role because it's bound to glycine, an amino acid that supports calming pathways. This form is highly bioavailable and gentle on the gut, making it ideal for daily use and evening supplementation, especially if you’re looking to support relaxation, nervous system balance, and sleep quality.

Magnesium is essential for normal muscle contraction and relaxation. When magnesium levels are low, muscles may remain in a state of tension. Our formula includes Magnesium Citrate because of its strong absorption profile and its ability to support healthy muscle function, relieve everyday tension, and aid recovery after physical exertion.

Our formula includes Magnesium Citrate because of its strong absorption profile and its ability to support healthy muscle function, relieve everyday tension, and aid recovery after physical exertion.
Cellular Energy Production
Magnesium plays a central role in cellular energy metabolism. Every molecule of ATP (adenosine triphosphate), which is the primary energy currency used by our cells, must bind to magnesium in order to become biologically active. We added Magnesium Malate to our formula specifically because malic acid is a key compound in the mitochondrial Krebs cycle, the process through which cells convert nutrients into usable energy. This pairing helps support efficient ATP production and contributes to more stable daytime energy and reduced fatigue.
Digestive Support
Magnesium also plays a role in supporting normal digestive function. Magnesium Citrate contributes to healthy bowel motility and digestive comfort. We included it at a dose that supports regularity without the laxative effect associated with lower-quality magnesium forms.

A blend of three highly bioavailable forms of magnesium.

We believe in full transparency about what goes into our formulas. Unlike many over-the-counter supplements which rely on magnesium oxide, a cheap form of magnesium poorly absorbed by the body (which reduces its overall effectiveness), our formula uses chelated and organic magnesium compounds chosen for their stability, tolerability, and bioavailability.

Why this formula works?

"One form of magnesium can't do it all. We combined bisglycinate for calm and superior absorption, malate for energy via the Krebs cycle, and citrate for rapid uptake - three highly bioavailable forms working together to deliver 300 mg of elemental magnesium where it's needed most."

Sophie Chabloz Chief Science Officer

Magnesium Bisglycinate

220 mg elemental magnesium

Magnesium bisglycinate is a chelated form of magnesium bound to the amino acid glycine. This form of Magnesium is known for its high absorption and excellent gastrointestinal tolerance. It can cross the blood-brain barrier and support the nervous system, reducing anxiety and improving sleep quality.

Magnesium Malate

40 mg elemental magnesium

Magnesium malate combines magnesium with malic acid, a naturally occurring compound involved in the Krebs cycle, the process through which cells convert nutrients into usable energy (ATP). This form is ideal for supporting cellular energy metabolism, contributing to more stable daytime energy and reduced fatigue.

Magnesium Citrate

40 mg elemental magnesium

Magnesium citrate is a highly soluble form of magnesium known for its efficient absorption in the digestive tract. Because of its strong absorption profile, Magnesium Citrate helps support healthy muscle function, relieve everyday muscle tension, and aid physical recovery after exertion. It also contributes to normal digestive function by supporting healthy bowel motility and digestive comfort.

Magnesium Basics

The science behind magnesium and cellular health

Magnesium is THE longevity mineral powering over 300 reactions in your body, yet most adults are not getting enough of it. From nervous system regulation and muscle function, to cellular energy production and your body's stress response, magnesium is involved in nearly every process that determines how well you sleep, recover, and perform.

At the cellular level, magnesium plays a central role in mitochondrial function and ATP production, which is the process through which your cells generate usable energy. It also contributes to DNA stability, electrolyte balance, and normal muscle and nerve signalling.

Despite its importance, modern diets often provide less magnesium than the body requires. Soil depletion, food processing, and increased physiological demands from stress, exercise, and poor sleep can all contribute to lower magnesium intake and higher magnesium utilisation.

Many over-the-counter magnesium supplements also rely heavily on magnesium oxide, a cheap form of magnesium which is poorly absorbed by the body and therefore not effective.

Maintaining adequate magnesium levels is increasingly recognised as an important foundation for sleep quality, physical recovery, and long-term metabolic health, which is why picking the right form of magnesium can make a big difference in your results.

Not all magnesium supplements are absorbed equally. The effectiveness of a magnesium supplement depends largely on the chemical form in which magnesium is delivered.
Many standard supplements rely on magnesium oxide, a form that contains a high percentage of elemental magnesium but is known for relatively poor absorption in the body. Because it is not easily absorbed, a large portion may remain in the digestive tract rather than reaching tissues where magnesium is needed.
More advanced formulations instead use organic or chelated magnesium compounds, which are generally better tolerated and more easily absorbed.
Different forms of magnesium also have different benefits and characteristics. We’ve outlined some of them below:
Magnesium Oxide: This is the most common form found in supermarket supplements. It has a very high "elemental" weight, which looks great on the label, but your body only absorbs about 4% of it. The rest stays in your gut and often causes a laxative effect. We call this a "filler" magnesium.
Magnesium Bisglycinate: Here, magnesium is bound to the amino acid glycine. This is the "gold standard" for relaxation. Because it is highly bioavailable and can cross the blood-brain barrier, it is incredible for calming the nervous system, reducing anxiety, and improving sleep quality.
Magnesium Malate: This form is bound to malic acid, which plays a key role in the Krebs cycle (how your cells create energy). It is the best choice for those dealing with daytime fatigue or "brain fog" and supports muscle recovery after exercise.
Magnesium Citrate: This is a very popular, well-absorbed form. It is excellent for replenishing magnesium levels quickly and helps with muscle tension and digestive regularity.
Magnesium Threonate: This is the "new kid on the block." It has some good data regarding cognitive health and its ability to cross the blood-brain barrier. However, it is extremely expensive. While it is promising, the current evidence doesn't yet prove it is significantly more effective for your brain than a high-quality Bisglycinate.
Instead of relying on a single form of magnesium, our Magnesium Complex combines three complementary, highly bioavailable forms of magnesium: magnesium bisglycinate, magnesium malate, and magnesium citrate for added benefits:
- Magnesium Bisglycinate is a chelated form of magnesium bound to glycine, an amino acid that supports calming pathways. This form is highly bioavailable and gentle on the gut, making it ideal for daily use and evening supplementation, especially if you’re looking to support relaxation, nervous system balance, and sleep quality.
- Magnesium Citrate is a highly soluble form of magnesium known for its efficient absorption in the digestive tract. Magnesium itself is essential for normal muscle contraction and relaxation, and when magnesium levels are low, muscles may remain in a state of tension. Because of its strong absorption profile, Magnesium Citrate helps support healthy muscle function, relieve everyday muscle tension, and aid physical recovery after exertion. It also contributes to normal digestive function by supporting healthy bowel motility and digestive comfort.
- Magnesium Malate combines magnesium with malic acid, a naturally occurring compound involved in the Krebs cycle, the process through which cells convert nutrients into usable energy (ATP). This form is ideal for supporting cellular energy metabolism, contributing to more stable daytime energy and reduced fatigue.
Together, these forms provide 300 mg of elemental magnesium per daily serving, helping support the biological systems most dependent on magnesium: the nervous system, muscular recovery, and cellular energy metabolism.

Feel the dıfference

Clinical research on magnesium shows:

300+

biochemical reactions require magnesium. Magnesium acts as a cofactor in more than 300 enzymatic reactions involved in energy production, muscle contraction, nervous system signalling, and metabolic regulation.

70 - 80%

of adults may not reach recommended magnesium intake. Dietary studies across Western Europe suggest that a large proportion of adults consume less magnesium than recommended due to modern diets and soil depletion.

~25%

of adults show measurable magnesium deficiency. Clinical observations indicate that a significant share of the population presents suboptimal magnesium levels in blood measurements.

Essential

for cellular energy production. ATP - the primary energy molecule used by cells - must bind to magnesium in order to become biologically active, making magnesium essential for mitochondrial function and daily energy metabolism.

What to expect over time

Magnesium plays a central role in sleep regulation, muscle function, and cellular energy production. As magnesium intake becomes consistent, the body’s magnesium levels gradually replenish, allowing these processes to function more efficiently. Over time, this can contribute to better sleep quality, improved muscle recovery, and more stable daily energy levels, with many individuals noticing the first changes within the first few weeks of regular use.

2 - 4 weeks

Calmer nervous system and deeper sleep

As magnesium intake becomes consistent, the nervous system begins to stabilise. You may notice improved relaxation, better sleep quality, and reduced muscle tension as magnesium supports normal nervous system function and helps regulate the body’s stress response.

1–3 months

Improved energy and physical recovery

As magnesium levels in the body gradually replenish, cells are better able to produce ATP, which is the molecule responsible for cellular energy. During this phase, many people experience more stable daily energy, improved muscle recovery after physical activity, and greater resilience to everyday stress.

3+ months

Long-term metabolic and structural support

Maintaining proper magnesium levels also supports normal muscle function, psychological balance, and electrolyte regulation. Over time, this also contributes to the maintenance of healthy bones and teeth, forming an important nutritional foundation for long-term health and vitality.
