Whether you’re waking from nocturnal leg cramps, battling persistent muscle tension after a workout, or struggling with restless sleep, inadequate magnesium can be at the root of your discomfort. As a cofactor in over 300 enzymatic reactions, magnesium regulates muscle contraction, blood pressure, and nerve transmission. Low dietary intake—often due to modern soil depletion and processed foods—leaves millions deficient. Symptoms range from mild irritability and fatigue to severe muscle cramps, insomnia, and even arrhythmias. Over time, inadequate magnesium can contribute to osteoporosis, migraine headaches, and chronic stress responses.
In this article, you’ll explore how Solgar Magnesium Citrate provides a highly absorbable magnesium source to support muscle relaxation, nerve function, and overall well-being. We’ll explain why citrate salt is preferable to oxide forms, outline effective dosing strategies, and share tips to complement supplementation with dietary and lifestyle adjustments. By adding Solgar Magnesium Citrate to your daily regimen, you can optimize cellular function and restore balance to restless muscles and frazzled nerves.

Why Magnesium Matters and Why Citrate Is Best
Magnesium operates as a natural calcium antagonist—calming excess calcium influx in muscle cells and nerves, thereby preventing spasm and over-excitation. It also contributes to ATP synthesis (cellular energy) and bone mineralization alongside calcium and vitamin D. However, not all magnesium supplements are created equal:
- Magnesium Oxide: Although high in elemental magnesium (~60%), its bioavailability is limited (as low as 4%). Many users experience gastrointestinal distress—such as loose stools—if taken at doses above 200 mg.
- Magnesium Citrate: Formed by binding magnesium to citric acid, this salt boasts superior solubility and absorption (30–40% higher than oxide). Citrate also exerts gentle osmotic effects in the intestines, easing occasional constipation without harsh laxative action.
- Other Forms (Glycinate, Malate, Threonate): Each offers specific benefits (glycinate for sleep, malate for energy, threonate for cognitive support), but their elemental magnesium content and costs vary. Citrate remains a balanced choice for general muscle and nerve support.
Solgar Magnesium Citrate delivers 100 mg of elemental magnesium per tablet in a 2:1 citrate-to-magnesium ratio—ensuring efficient absorption. At two tablets daily, you receive 200 mg to support daily requirements (adult RDA ranges from 310–420 mg depending on age and sex). Unlike oxide forms that largely sit unabsorbed in the colon, magnesium citrate readily enters circulation, providing prompt relief for muscle cramps and neuromuscular irritability.
How Solgar Magnesium Citrate Works
1. Muscle Relaxation and Cramp Prevention
Skeletal muscle contraction requires calcium entry into muscle fibers; magnesium competes with calcium at binding sites, preventing excessive contraction. When magnesium is low, unchecked calcium leads to involuntary muscle spasms—especially in the calves and feet at night. By maintaining adequate magnesium levels, Solgar Magnesium Citrate ensures muscle cells repolarize efficiently after each contraction, reducing cramp frequency and intensity. Clinical data show that 200–400 mg of elemental magnesium daily can cut nocturnal cramping episodes by over 50%.
2. Neurological Calm and Sleep Support
Magnesium modulates NMDA (N-methyl-D-aspartate) receptors in the brain—preventing excitatory overstimulation that can manifest as anxiety, restlessness, or difficulty falling asleep. It also enhances GABA (gamma-aminobutyric acid) activity, the primary inhibitory neurotransmitter, promoting relaxation and supporting deeper, more restorative sleep phases. Nighttime dosing of 200 mg of Solgar Magnesium Citrate—about 30 minutes before bed—has been shown to improve sleep latency (time to fall asleep) and sleep efficiency (time spent asleep vs. time in bed).
3. Cardiovascular and Bone Health
Magnesium influences vascular tone by regulating smooth muscle in arterial walls. Adequate levels help maintain healthy blood pressure by facilitating vasodilation. Further, magnesium is critical for activating vitamin D and for the crystallization of hydroxyapatite in bone. Long-term supplementation with 200–300 mg elemental magnesium daily can support bone mineral density—especially in individuals with low dietary intake or post-menopausal women at higher osteoporosis risk.
Integrating Magnesium Citrate into Your Routine
For optimal results, follow these guidelines:
- Dosage & Timing: Take one tablet (100 mg elemental magnesium) twice daily—once with breakfast and once 30 minutes before bed—to support diurnal energy metabolism and nocturnal muscle recovery.
- Hydration: Magnesium citrate’s osmotic effect can draw water into the intestines. Drink at least 8–10 cups (2–2.5 L) of water daily to facilitate absorption and prevent loose stools.
- Dietary Synergies: Pair magnesium with calcium-rich foods—leafy greens, almonds, yogurt—and vitamin D sources—fatty fish, fortified dairy—to support coordinated bone and muscle health. Avoid excessive alcohol and caffeine, which deplete magnesium stores.
- Exercise & Stretching: Incorporate dynamic stretching before workouts and static stretching after to complement magnesium’s muscle-relaxing properties. Post-exercise, a 200 mg dose helps reduce DOMS (delayed onset muscle soreness) and promotes recovery.
- Stress Management: Chronic stress raises cortisol, which increases urinary magnesium excretion. Incorporate mindfulness—deep breathing, yoga, or meditation—to reduce stress hormones and conserve magnesium levels.
By integrating these habits with Solgar Magnesium Citrate supplementation, you create a comprehensive muscle, nerve, and bone health strategy—minimizing cramps, improving sleep, and reinforcing overall resilience.
Safety, Side Effects & Contraindications
Solgar Magnesium Citrate is well tolerated by most users, but consider these points:
- Possible Gastrointestinal Effects: High single doses (>350 mg elemental) can lead to mild diarrhea. If this occurs, lower the dose to one tablet daily for a week, then gradually increase.
- Kidney Function Considerations: Individuals with renal impairment may accumulate magnesium and risk hypermagnesemia (high blood magnesium), which can cause weakness, low blood pressure, and cardiac arrhythmias. Consult your healthcare provider before use if you have kidney disease.
- Drug Interactions:
- Bisphosphonates (alendronate, risedronate): Magnesium can bind to these medications, reducing their absorption. Take magnesium at least 2 hours before or after bisphosphonate dosing.
- Antibiotics (tetracyclines, fluoroquinolones): Similar binding can occur; separate dosing by 2–4 hours to ensure antibiotic efficacy.
- Diuretics (loop, thiazide): May increase magnesium loss. Monitor levels and adjust dose under medical supervision.
- Proton Pump Inhibitors (PPIs): Long-term PPI use can impair magnesium absorption. If you take PPIs, ensure regular magnesium supplementation and consider periodic serum magnesium checks.
- Pregnancy & Breastfeeding: Magnesium is essential during pregnancy to reduce preeclampsia risk and support fetal development. Most OB/GYNs consider 200 mg daily safe—but always discuss with your provider before starting any new supplement.
Following dosage guidelines and reviewing potential drug interactions ensures safe, effective use.
