At Agent Nateur, every supplement begins with a question: how can we design something the body truly recognizes? Not a capsule of isolated nutrients, but a formulation that communicates with the body at the deepest cellular level.

When we created holi (mag), our goal was to craft a magnesium that did more than relax the muscles. We wanted to nourish the mind, calm the nervous system, and support energy, focus, and sleep simultaneously. To achieve this, we combined Magtein with five complementary forms of magnesium for full-spectrum absorption and performance.

Each form targets a unique pathway in the body, creating a synergistic effect that helps you feel calm, clear, and deeply restored.

Why magnesium matters

Magnesium is often called the “master mineral” because it is involved in over 300 enzymatic reactions in the body. It supports nervous system regulation, hormone balance, cardiovascular health, and energy production. Yet most people are deficient.

Stress, caffeine, alcohol, environmental toxins, and soil depletion all lower magnesium levels. When magnesium is low, everything feels off: sleep becomes lighter, anxiety heightens, and concentration wanes.

holi (mag) was designed to replenish these stores intelligently, pairing neuroscience-backed ingredients with the most bioavailable forms of magnesium found in nature.

Magtein: the brain magnesium

Magtein, also known as magnesium L-threonate, is the hero of our formula. It was developed at MIT after years of research into how magnesium affects brain aging and memory.

While most forms of magnesium work primarily in the body, Magtein is the only compound proven to cross the blood-brain barrier effectively. Once inside the brain, it increases synaptic density, essentially improving communication between neurons.

Clinical studies have shown that Magtein can:

• Support cognitive performance, focus, and short-term memory
• Reduce feelings of mental fatigue and “brain fog”
• Promote relaxation without sedation
• Support healthy sleep cycles by regulating NMDA and GABA receptors

We chose Magtein because it represents a new generation of nutrient science - one that not only replenishes but restores.

The five supporting forms of magnesium

1. Magnesium glycinate

This is one of the most gentle and bioavailable forms of magnesium, bound to the amino acid glycine. It is known for its soothing effects on the nervous system and its ability to promote restful sleep without digestive upset.

Magnesium glycinate is ideal for relaxation, emotional balance, and muscle recovery. It works synergistically with Magtein by calming the body while Magtein nourishes the mind.

2. Magnesium malate

Bound to malic acid, a compound naturally found in fruit, magnesium malate supports cellular energy and helps combat fatigue. It plays a key role in the Krebs cycle, the body’s natural energy production process.

This form is especially supportive for people who feel tired or experience brain fog. It provides sustained vitality while maintaining calm focus.

3. Magnesium citrate

This form is easily absorbed and helps regulate digestion and muscle function. It supports detoxification by helping the body flush out toxins.

Magnesium citrate is also valuable for balancing calcium and preventing muscle tension or cramps. It ensures the entire body remains in flow.

4. Magnesium orotate

Orotate is a carrier molecule that transports magnesium directly into the mitochondria, where cellular energy is made. This form is particularly beneficial for heart health, cellular repair, and endurance.

It nourishes the cardiovascular system, supports healthy circulation, and contributes to ATP production, which fuels every cell in the body.

5. Magnesium taurate

This form combines magnesium with taurine, an amino acid known for its calming and cardiovascular benefits. Together, they help regulate blood pressure, stabilize mood, and support relaxation without fatigue.

Magnesium taurate is ideal for emotional balance and nervous system health. It also supports the body’s natural response to stress by protecting the heart from tension-related strain.

The synergy

Each form of magnesium in holi (mag) was chosen not in isolation but for its ability to complement the others.

• Magtein nourishes the brain
• Glycinate calms the body
• Malate restores energy
• Citrate supports detoxification
• Orotate fuels mitochondria
• Taurate soothes the heart and nerves

Together, they deliver magnesium to every part of the body: brain, muscles, heart, and cells- creating a harmonious balance of focus, calm, and energy.

This synergy is what makes holi (mag) so unique. It is not a single-action supplement
