Not all magnesium supplements work the same way. If you have ever tried a basic drugstore magnesium tablet, you may have experienced an upset stomach with little improvement in sleep or muscle comfort. Source Naturals Ultra-Mag™ (SKU: SN2953) solves this common pitfall by binding pure elemental magnesium to five specialized carriers (citrate, glycinate, malate, taurinate, and succinate) and pairing them with Vitamin B6 for optimal cellular uptake.
✓420 mg of Bioavailable Elemental Magnesium (100% Daily Value): Meets your full daily nutritional requirement in three gentle plant-based capsules.
✓Targeted Multi-System Absorption: Combines five organic forms designed to nourish the brain, skeletal muscles, cardiovascular system, and cellular energy cycles simultaneously.
✓Active Vitamin B6 Co-Factor (30 mg Pyridoxine HCl): Clinically shown to transport magnesium molecules across cellular membranes for deeper systemic delivery.
✓Gentle on Sensitive Digestion: Formulated without harsh, poorly absorbed magnesium oxide to help minimize unwanted laxative effects.
✓100% Certified 360 Vegan Capsules: 120 full servings per bottle; free of gluten, soy, dairy, eggs, wheat, sugar, and synthetic preservatives.

Why 5 Forms of Magnesium Beat Standard Single-Ingredient Pills
Think of magnesium like a passenger that requires an escort vehicle to pass through your intestinal wall and enter your bloodstream. In ordinary store supplements, manufacturers often use magnesium oxide—an inexpensive, chalky compound where magnesium is bound to oxygen. Because human gut cells struggle to absorb magnesium oxide (studies indicate average absorption rates as low as 4%), the unabsorbed mineral remains in the bowel, drawing in water and causing rapid diarrhea rather than reaching your muscles or brain.
Source Naturals Ultra-Mag™ solves this by using five distinct "escorts"—naturally occurring organic acids and amino acids. Each carrier unlocks a separate cellular pathway in your digestive tract:
1. Magnesium Glycinate (Chelated with Glycine)
Magnesium is bound to the calming amino acid glycine. Glycine travels straight to the nervous system, where it helps silence evening mental chatter and promotes deeper non-REM sleep cycles without triggering gut sensitivity.
2. Magnesium Malate (Bound to Malic Acid)
Malic acid is an essential compound in the cellular Krebs Cycle—the metabolic engine that converts food into adenosine triphosphate (ATP) energy. This form excels at easing tight, fatigued muscle tissue and combating daytime physical exhaustion.
3. Magnesium Taurinate (Chelated with Taurine)
Taurine is a specialized amino acid concentrated in heart muscle fibers and vascular walls. It helps stabilize cell membranes, regulate cardiac rhythm, and maintain flexible arterial elasticity for balanced blood pressure support.
4. Magnesium Citrate (Bound to Citric Acid)
One of the most clinically verified, water-soluble forms of magnesium available. Citrate enters systemic circulation quickly, supporting rapid neuromuscular recovery after exercise and promoting comfortable, regular bowel motility.
5. Magnesium Succinate (Succinic Acid Complex)
Succinate plays a direct role in mitochondrial oxidative phosphorylation. By replenishing intermediate enzymes needed by cellular powerhouses, it aids long-term recovery and whole-body stamina.
The Vitamin B6 Advantage: The Cellular Key That Unlocks Magnesium
Getting magnesium into your stomach is only half the battle; the true challenge is transporting it inside your cells, where over 300 biochemical enzymes depend on it every second. This is where the formulation of Source Naturals Ultra-Mag™ stands out from standalone supplements.
What Peer-Reviewed Clinical Research Reveals:
In a landmark randomized, investigator-blinded trial published in PLOS ONE (Pouteau et al., 2018), researchers examined adults suffering from significant stress and low mineral levels. Subjects were split into two groups: one receiving elemental magnesium alone, and the other receiving magnesium combined with Vitamin B6.
The Outcome: Individuals receiving the combined magnesium and Vitamin B6 protocol achieved a 24% greater reduction in overall stress scores compared to those taking magnesium alone. Researchers noted that pyridoxine acts as an intracellular chaperone, helping shuttle magnesium ions across dense cellular lipid membranes into erythrocytes and neurons where they quiet down hyperactive stress signaling.
Each daily serving of Ultra-Mag™ provides 30 mg of Vitamin B6 (as Pyridoxine HCl)—delivering 1,765% of your Daily Value to optimize cellular uptake, support neurotransmitter synthesis (serotonin, dopamine, and GABA), and ensure that every milligram of magnesium works for your body.
Key Evidence-Based Health Benefits
1
Restful Sleep Support & Natural Evening Relaxation
Magnesium functions as nature's physiological chill pill. It binds directly to GABA-A receptors in the central nervous system, boosting the primary neurotransmitter responsible for downshifting active mental chatter into serene calmness. At the same time, magnesium blocks excess glutamate—an excitatory brain neurotransmitter that keeps your mind racing at 2:00 AM.
Clinical Evidence: A double-blind, placebo-controlled study in the Journal of Research in Medical Sciences (Abbasi et al., 2012) demonstrated that daily magnesium supplementation statistically increased sleep duration, sleep efficiency, and natural serum melatonin levels while suppressing serum cortisol (the stress hormone).
2
Skeletal Muscle Recovery & Relief from Sudden Night Cramps
Your muscles require calcium to contract and magnesium to release. When you exercise, sweat, or experience high stress, intracellular magnesium is drained. Without adequate magnesium to counteract calcium, muscle fibers remain locked in a semi-contracted state, resulting in painful nocturnal leg cramps, twitches, and stiff back soreness. Ultra-Mag™ replenishes intracellular stores, allowing tight fibers to relax quickly.
3
Cellular Energy (ATP) & Mitochondrial Stamina
Many people assume caffeine creates energy, but true biological energy is generated inside the mitochondria in the form of ATP. Biochemically, ATP must be bound to a magnesium ion (forming an Mg-ATP complex) to become biologically active. Ultra-Mag's combination of magnesium malate and succinate feeds directly into the cellular energy pathways, helping lift midday fatigue without caffeine jitters.
4
Cardiovascular Rhythm & Healthy Endothelial Function
Magnesium regulates the electrical signals that govern smooth, rhythmic heartbeats while modulating calcium flow in vascular smooth muscle cells. Combined with taurine, it assists the body in maintaining flexible, dilated blood vessels, contributing to healthy blood pressure levels already within the normal range.

How to Take Ultra-Mag™ for Best Results (Dosage & Timing)
To maximize mineral absorption and avoid common digestive issues, follow these evidence-based best practices:
For Everyday Maintenance
Take 1 to 2 capsules daily with meals. Taking minerals alongside whole food stimulates gastric acid secretion, which breaks down mineral chelates for seamless intestinal absorption.
For Sleep & Evening Calm
Take 2 to 3 capsules 45 minutes before bedtime with a small glass of water or an evening chamomile tea. This timing aligns with your body's natural circadian melatonin elevation.
For Sensitive Stomachs
If you have a sensitive digestive tract, split your dose: take 1 capsule with breakfast, 1 with lunch, and 1 with dinner. Spreading the dose ensures steady blood levels with zero bowel distress.
Important Safety Information, Contraindications & Drug Interactions
While magnesium is an essential macro-mineral with an exceptional safety track record, certain medical conditions and pharmaceutical therapies warrant close medical supervision:
Impaired Kidney Function: Healthy kidneys filter and excrete excess magnesium effortlessly. However, individuals with chronic kidney disease (CKD) or renal failure must consult a nephrologist before supplementing, as impaired filtration can trigger hypermagnesemia (abnormally elevated blood magnesium).
Antibiotic Separation (Quinolones & Tetracyclines): Magnesium binds to certain oral antibiotics (such as ciprofloxacin, levofloxacin, doxycycline, and tetracycline) in the stomach, preventing their absorption. Take your antibiotic at least 2 hours before or 4 to 6 hours after your Ultra-Mag™ dose.
Blood Pressure Medications: Because magnesium naturally relaxes vascular smooth muscle, combining high-dose supplementation with calcium channel blockers or ACE inhibitors may have an additive effect. Monitor your blood pressure readings alongside your doctor.
Pregnancy & Nursing: If you are pregnant, planning to become pregnant, or nursing, consult your OB-GYN before adding any dietary supplement to your regimen.
