If you often feel tense muscles, restless nights, or daily fatigue, your body might simply be running low on its most important mineral spark plug. Source Naturals Ultra-Mag™ is an advanced, high-absorption dietary supplement that delivers 420 mg of elemental magnesium across five distinct chelated forms, paired with active Vitamin B6 to maximize cell absorption without stomach upset.
Why Standard Magnesium Often Falls Short
Many generic supplements rely exclusively on magnesium oxide, an inorganic compound where less than 5% is absorbed by the human digestive tract, with the rest pulling water into the colon and causing loose stools. Ultra-Mag binds magnesium to organic amino acids and organic acids, allowing the mineral to cruise smoothly through your intestinal walls and directly into your tissues.
The 5-in-1 Chelate Synergy: How Each Form Works Inside Your Body
No single type of magnesium solves every physical demand. Different tissues prefer different carrier molecules. Ultra-Mag blends five specialized forms to deliver balanced full-body coverage:
1. Magnesium Glycinate (Bisglycinate) – The Calming Mineral
Magnesium bound to glycine, a gentle amino acid known to calm neural signaling. Glycine easily crosses the intestinal barrier via peptide channels, making it remarkably easy on the stomach while promoting mental peace, nervous system balance, and restful sleep.
2. Magnesium Malate – Cellular Energy & Muscle Soreness
Magnesium linked to malic acid, a natural fruit acid that plays a direct role in the Krebs cycle (your cell's engine for producing ATP energy). This form is favored by active individuals looking to soothe daytime muscle stiffness and sustain physical stamina.
Taurine is an amino acid concentrated in heart muscle and brain tissue. It helps regulate the flow of calcium ions in and out of cells, working alongside magnesium to support regular heart rhythms and vascular tone.
One of the most clinically validated forms for raising blood magnesium levels quickly. When balanced within this complex, citrate provides high cellular uptake and supports healthy digestion and metabolic regularity.
5. Magnesium Succinate – Mitochondrial Fuel
Succinic acid is another direct participant in cellular respiration and energy production, providing metabolic support during physical exertion and mental stress.
The Vitamin B6 Catalyst (30 mg Pyridoxine HCl)
Vitamin B6 acts like a cellular key, unlocking cell membranes so magnesium can move out of the bloodstream and directly inside the cell where it is needed. Clinical studies show combining B6 with magnesium yields significantly greater reductions in stress and tension than magnesium taken alone.
Clinically Backed Health Benefits
✓Relieves Nighttime Leg Cramps & Muscle Tension:
Calcium tells muscle fibers to contract; magnesium tells them to relax. When dietary magnesium is low, calcium floods muscle cells, triggering spasms, twitches, and painful night cramps. Ultra-Mag helps restore proper electrolyte harmony.
✓Supports Deeper, Restorative Sleep:
Magnesium binds to and stimulates Gamma-Aminobutyric Acid (GABA) receptors in the brain. GABA is your body's natural relaxation neurotransmitter that slows down racing evening thoughts and prepares your mind for restorative slow-wave sleep.
✓Healthy Blood Pressure & Heart Health:
By supporting endothelial function and the smooth muscle relaxation of arterial walls, magnesium promotes healthy blood flow and assists in maintaining blood pressure numbers already within normal ranges.
✓Bone Mineralization & Calcium Balance:
Roughly 60% of all magnesium in your body resides in your bones. Magnesium activates alkaline phosphatase and converts Vitamin D into its active hormonal form (calcitriol), ensuring calcium is deposited into bone matrices rather than soft tissues or arteries.

Suggested Use, Optimal Timing & Safety Information
How to Take Ultra-Mag:
Take 1 or 2 tablets daily with a meal, or as directed by your healthcare professional. Taking magnesium with food supports optimal digestion and gastric comfort.
Timing Pro-Tip: If your goal is restful sleep and evening muscle relaxation, take 1 to 2 tablets with your evening dinner or 45 minutes before bedtime. If you are using it primarily for daytime stamina and workout recovery, split the dose: take 1 tablet with breakfast and 1 tablet with dinner.
Medical Precautions & Interactions
Kidney Considerations: Individuals with significant renal impairment or kidney disease should consult their physician before taking magnesium, as compromised kidneys may have difficulty clearing excess mineral levels.
Medication Timing: Magnesium chelates can bind to certain medications and reduce their absorption. Take Ultra-Mag at least 2 to 4 hours apart from tetracycline or fluoroquinolone antibiotics, bisphosphonates (osteoporosis drugs), and thyroid hormone replacements (such as levothyroxine).
Pregnancy & Nursing: If you are pregnant, planning to become pregnant, or breastfeeding, consult your healthcare practitioner prior to beginning supplementation.
Frequently Asked Questions (FAQ)
Why does Ultra-Mag combine five different types of magnesium instead of just one?
Each magnesium salt interacts differently with your digestive system and bodily tissues. Citrate and malate excel at cellular uptake and energy production in muscles, glycinate targets neurological relaxation and sleep, taurate concentrates in heart tissue, and succinate supports the mitochondria. By blending all five, Ultra-Mag avoids saturating a single intestinal absorption pathway, maximizing total cellular retention while minimizing digestive sensitivity.
Will Source Naturals Ultra-Mag cause an upset stomach or loose stools?
Loose stools are predominantly caused by unabsorbed magnesium lingering in the intestines, drawing water into the bowel through osmosis (common with cheap magnesium oxide). Because Ultra-Mag utilizes chelated and organic acid complexes that enter blood circulation rapidly, gastrointestinal discomfort is far less likely. If you have an exceptionally sensitive stomach, begin with 1 tablet daily with a meal and gradually step up to 2.
Why is Vitamin B6 included in this formula?
Vitamin B6 acts as a biological transporter for magnesium. Scientific trials have demonstrated that Vitamin B6 helps ferry magnesium across cell membranes into the intracellular space where enzymes utilize it. Furthermore, both nutrients act as cofactors in synthesizing serotonin and GABA, amplifying stress reduction and mental calm.
How long does it take to feel results from Ultra-Mag?
Many users report noticeable muscle relaxation and easier sleep onset within the first 2 to 5 days of regular use. However, replenishing deep tissue and bone stores of magnesium typically requires consistent daily supplementation over 4 to 8 weeks.
Are Ultra-Mag tablets vegetarian and free from gluten?
Yes. Source Naturals Ultra-Mag (SN0803) is 100% suitable for vegetarians. It contains zero gluten, wheat, soy, dairy, egg, yeast, artificial colors, or artificial preservatives.
