Magnesium Citrate, Pure Powder: Metabolic Energy, Muscle Relaxation and Nervous Balance – Superior Bioavailability for Bones, Sleep and Daily Performance

Magnesium Citrate, Pure Powder, Now Foods provides a concentrated source of highly bioavailable magnesium in the form of magnesium citrate. Each serving supplies 450 mg elemental magnesium (from 3,000 mg magnesium citrate), efficiently covering daily requirements and supporting key functions such as energy (ATP) production, muscle contraction and relaxation, nerve transmission, protein synthesis, and bone mineralization. Magnesium is a cofactor for over 300 enzymatic reactions, being involved in glucose metabolism, electrolyte balance, nucleic acid synthesis, and cell membrane stability. The pure powder form allows flexible dosing and easy dissolution in water or beverages, ideal for daily use, training, or periods with increased metabolic demands.

Detailed Benefits of Magnesium Citrate (Pure Powder)

• Supporting Optimal Cellular Energy Levels

Energy is the foundation of day-to-day performance, and magnesium plays a central role in oxidative phosphorylation and ATP synthesis.
✅ As an essential cofactor in Krebs cycle enzymes, magnesium facilitates the conversion of nutrients into usable energy.
✅ Promotes mitochondrial stability and bioenergetic efficiency, supporting overall tone.
✅ Contributes to the reduction of fatigue sensation associated with functional magnesium deficiencies.
The result: coherent vitality, a more sustained daily rhythm, and a better ability to handle complex tasks.

• Muscle Relaxation, Efficient Contraction and Recovery

Magnesium regulates calcium flux in muscle fibers and participates in membrane repolarization.
✅ Supports muscle relaxation after intense contractions, contributing to post-exercise comfort.
✅ Participates in synergy with potassium and calcium for neuromuscular impulse.
✅ May help maintain muscle elasticity and coordination, useful both in daily activities and in sports.
Perceived benefit: muscles that feel more “rested”, with reduced tension and more harmonious recovery.

• Nervous System Balance and Mental Clarity

The nervous system relies on ion homeostasis and on the efficiency of magnesium-dependent enzymes.
✅ Contributes to synaptic transmission and to the excitatory–inhibitory balance at the neuronal level.
✅ Supports resilience to everyday stress, promoting calm and concentration.
✅ Helps sleep quality through its role in relaxation and neuromediator regulation.
The result: balanced mental state, improved focus, and more restorative rest.

• Bone Health and Synergy with Vitamins D and K

More than 50% of magnesium is found in bone tissue, influencing mineral density and calcium metabolism.
✅ Supports osteoblastic activity and structural stability of bone.
✅ Participates in the activation of vitamin D, optimizing calcium absorption.
✅ Supports phospho-calcium balance for a strong skeleton in the long term.
Functional conclusion: well-supported bone infrastructure and comfortable mobility.

• Glucose Metabolism and Electrolyte Balance

Magnesium takes part in glucose phosphorylation and in the regulation of membrane transporters.
✅ Supports carbohydrate metabolism, contributing to stable energy profiles.
✅ Helps maintain electrolyte balance (together with sodium, potassium, calcium), relevant for hydration and neuromuscular tone.
✅ Contributes to enzymatic function involved in fatty acid oxidation and protein synthesis.
Integrated benefit: better metabolic homeostasis and greater resilience to variations in effort or diet.

• Functional Cardioprotection and Circulatory Comfort

Magnesium supports electrical rhythm and vascular tone through effects on ion channels.
✅ Supports myocardial function through its role in cardiac repolarization.
✅ Promotes vascular relaxation, which contributes to circulatory comfort.
✅ Together with an active lifestyle and balanced nutrition, supports cardiovascular system performance.
The result: cardiometabolic support adapted to the daily rhythm.

• Digestion, Intestinal Comfort and Gastric Sensitivity

The citrate form has good solubility and can gently buffer pH, supporting digestive comfort.
✅ Soluble powder allows rapid mixing and easy absorption.
✅ Flexible dosing helps with fine-tuning according to individual needs.
✅ Contributes to motility and to magnesium-dependent digestive enzymes.
Practical benefit: good tolerance and easy integration into the routine.

• Sports Performance, Endurance and Reduced Perception of Effort

In intense activity, electrolyte losses and energy demands increase.
✅ Magnesium supports efficient contraction, recovery, and replenishment of energy stores.
✅ Helps maintain neuromuscular coordination in repetitive sets and consistency of effort.
✅ May help reduce cramps associated with electrolyte imbalances.
The result: continuity in training, a sensation of a “cleaner engine”, and more comfortable post-exercise phases.

• High-Bioavailability Form: Magnesium Citrate

Not all forms of magnesium are absorbed equally. Citrate is valued for its absorption profile and tolerability.
✅ 3,000 mg magnesium citrate provide 450 mg elemental magnesium, a clear indication of intake.
✅ The pure powder form offers versatility: can be mixed into water, smoothies, or post-workout beverages.
✅ No unnecessary excipients, focused on efficiency and purity.
Advantage: control over dosage and simple integration into your personal rhythm.

• Nutritional Synergies and Lifestyle

Magnesium’s effects are amplified by coherent choices.
✅ Adequate hydration and electrolyte intake (potassium, sodium) for optimal neuromuscular impulse.
✅ High-quality proteins, essential fatty acids, and fiber for a balanced metabolism.
✅ Vitamin D and vitamin K2 can support bone in synergy with magnesium.
Thus, magnesium becomes the central piece in a performance and wellbeing strategy.

• Suitable for Periods with Increased Demands

Stress, training, busy schedules, or dietary changes can increase magnesium needs.
✅ Pure powder allows adjustment according to season and activity volume.
✅ Rapid dissolution, neutral taste that is easy to integrate.
✅ Contributes to consistency in self-care routines.
The result: improved metabolic stability, neuromuscular calm, and sustained energy.

Magnesium Citrate, Pure Powder, Now Foods offers a rare combination of purity, bioavailability, and flexible dosing.

Directions for Use

Mix 1 level teaspoon of powder into at least 250 ml of cold water or cold juice. Add powder slowly while stirring. Take once daily with a meal. Pure magnesium citrate powder may increase the temperature of liquids upon contact; therefore, the recommended serving MUST be mixed into at least 250 ml of cold liquid to neutralize this reaction before ingestion.

Other Ingredients

None.
Not manufactured with wheat, gluten, soy, milk, egg, fish, shellfish, or tree nut ingredients. Produced in a GMP facility that processes other ingredients containing these allergens.
This magnesium citrate is a fully reacted mineral supplement.
