Magnesium Oxide, 200 mg – Cellular energy, muscles & nerves, strong bones and electrolyte balance 

Magnesium Oxide, 200 mg, Swanson is a concentrated formula that provides elemental magnesium from magnesium oxide, for support of cellular energy, muscle and nerve function, bone health and electrolyte balance. Each serving offers 400 mg magnesium (95% of Daily Value), a solid intake for meeting daily needs in an active lifestyle. Magnesium is cofactor in over 300 essential enzymatic reactions: ATP synthesis and utilization (cell energy), muscle contraction-relaxation, nerve transmission, maintaining normal blood pressure and bone mineralization. Magnesium oxide form offers high density of elemental magnesium, being easy to integrate into daily functional nutrition routine.

Detailed Benefits of Magnesium (from magnesium oxide)

• Cellular energy and ATP metabolism

Magnesium is the "key" that starts energy metabolism.
✅ Cofactor for kinases that transform nutrients into ATP – the cell's energy currency;
✅ Support for constant energy flow in tissues with high consumption (muscles, brain, heart);
✅ Contribution to reducing fatigue felt on busy days.
By supporting key enzymes, magnesium ensures the biochemical "engine" of daily vitality.

• Muscle function: fluid contraction-relaxation

Movement quality depends on balance between calcium (contraction) and magnesium (relaxation).
✅ Magnesium modulates calcium influx in muscle fibers – for coordinated contractions;
✅ Supports efficient post-contraction relaxation, useful in repeated activities;
✅ Muscle comfort in daily routine and after effort.
Adequate intake helps maintain pleasant and predictable mobility.

• Nervous system: neuronal transmission and "focused calm"

Magnesium influences neuronal excitability and neurotransmitter synthesis.
✅ Contributes to normal nervous system function;
✅ Supports mental clarity and adaptability in demanding periods;
✅ Helps maintain a state of "focused calm" throughout the day.
This fine regulation translates into more stable focus and mental resilience.

• Electrolyte balance and internal hydration

Electrolytes (magnesium, potassium, sodium) support fluid distribution and neuromuscular conduction.
✅ Magnesium contributes to electrolyte balance, important for effort rhythm;
✅ Support for proper functioning of membrane ion pumps;
✅ Perception of more consistent tone and endurance.
Correct electrolyte "ground" is visible in daily performance.

• Bones and teeth: intelligent mineralization

Magnesium is part of bone matrix and regulates enzymes involved in bone metabolism.
✅ Contributes to maintaining bone system and teeth health;
✅ Logical synergy with vitamin D3, K2 and calcium for balanced mineralization;
✅ Basic structural support for posture and mobility.
Coherent bone infrastructure means freedom of movement long-term.

• Heart and blood pressure

Cardiac tissue requires fine adjustment of electrochemical excitability.
✅ Magnesium contributes to normal cardiac muscle function;
✅ Supports vascular tone and blood pressure within physiological limits;
✅ "Fine-tuning" of daily rhythm in the context of variable efforts.
This balance feels like fluid circulation and daily comfort.

• Glucose metabolism and energy management between meals

Magnesium participates in enzymatic pathways related to glucose utilization.
✅ Helps maintain coherent energy metabolism;
✅ Contributes to more predictable tone variations between meals;
✅ Fits with routines that include balanced diet and movement.
Result: more stable perceived energy in daily schedule.

• Sleep and perceived relaxation

Through its role on nervous system and muscle relaxation, magnesium supports evening decompression.
✅ Support for natural transition toward relaxation;
✅ Nocturnal muscle comfort;
✅ Mornings with better recovery sensation.
Consistency in intake supports rest-activity rhythm.

• Performance and post-effort recovery

Physical effort intensifies magnesium use in muscles and mitochondria.
✅ Supports efficient energy conversion into mechanical work;
✅ Contributes to maintaining neuromuscular coordination;
✅ Helps recovery through its role in electrolyte balance.
This "invisible support" optimizes training experience.

• Digestive comfort and intestinal rhythm

Magnesium oxide has specific solubility that can favor water retention in intestinal lumen.
✅ Support for regular intestinal transit;
✅ Comfort felt in daily routine;
✅ Natural integration into digestive hygiene, alongside fiber and hydration.
Balanced digestive tract is synonymous with better general state.

• Why magnesium oxide? High density of elemental magnesium

Each form has particularities; oxide excels in magnesium content.
✅ High elemental magnesium intake per serving – diet "loading" efficiency;
✅ Practical for those seeking rapid coverage of needs;
✅ Easy to associate with other forms or with targeted vitamin-mineral support.
It's a simple choice for reaching daily targets.

• Fit with modern lifestyles

Alert pace, screens, stress and training – all increase nutritional demands.
✅ 400 mg magnesium per serving (95% DV) – solid base for full days;
✅ Compatible with varied diet, hydration and regular sleep;
✅ Easy to include in personal performance maintenance plans.
Consistency makes the difference in how you feel daily.

• Who Magnesium Oxide, Swanson is suitable for

The product is for people who seek:
✅ Daily energy and reducing felt fatigue;
✅ Optimal muscle & nerve function and electrolyte balance;
✅ Strong bones and teeth, cardiovascular support;
✅ Digestive comfort and smoother recovery after effort.
Naturally integrates into self-care plans, from office to gym.

Through its central role in energy metabolism, neuromuscular function, electrolyte balance and bone mineralization, Magnesium Oxide, 200 mg, Swanson offers substantial magnesium intake – 400 mg per serving – for a day when energy, mobility and clarity feel coherent.
