Source Naturals Magnesium Malate 1,250 mg — 180 Tablets

Recharge your energy at the cellular level and release stubborn muscular tension with Source Naturals Magnesium Malate 1250 mg. By bonding elemental magnesium with naturally energizing malic acid, this specialized formulation delivers superior bioavailability without the digestive distress common in standard mineral supplements.

How Magnesium Malate Works: Cellular Energy & Muscle Harmony

To understand why magnesium malate is widely regarded as the best bioavailable magnesium for daytime stamina, it helps to look inside your cells. Every cell in your body runs on a biochemical currency called adenosine triphosphate (ATP). However, ATP cannot become biologically active on its own — it must bind to a magnesium ion to create Mg-ATP, the actual spark plug used for muscle contractions, nerve signals, and metabolic repair.

What makes Source Naturals SN0262 unique is the partner molecule: malic acid. Malic acid is a naturally occurring fruit acid present in all living cells and acts as a central player in the Krebs cycle (the cellular engine that extracts energy from carbohydrates and healthy fats).

When combined, magnesium and malic acid work in synergy: the malate compound supports smooth cellular respiration and energy conversion, while magnesium counterbalances excess calcium to help taut, overworked muscle fibers unlock and relax. The result is lasting physical vitality throughout the day without nervous jitters or midday crashes.

Key Health Benefits of Source Naturals Magnesium Malate

• ✓ Sustained Cellular Stamina & Energy Production: Provides critical cofactors for over 300 metabolic enzymes, helping your body convert dietary fuel into cellular ATP to conquer persistent physical fatigue.
• ✓ Soothes Muscle Stiffness & Nighttime Cramps: Acts as a natural calcium blocker inside muscle cells, easing post-workout soreness, involuntary muscle twitches, and nocturnal leg cramping.
• ✓ Gentle on the Digestive Tract: Unlike magnesium oxide, which frequently causes loose stools and poor absorption, organic magnesium malate trihydrate is smoothly processed through the intestinal wall.
• ✓ Cardiovascular & Arterial Support: Aids regular endothelial function, supports healthy arterial elasticity, and helps maintain blood pressure already within a normal, healthy range.
• ✓ Assists Heavy Metal Chelation: Research shows malic acid has a natural chemical affinity to bind aluminum ions, assisting the kidneys in safely filtering and excreting excess environmental deposits.

How Does Magnesium Malate Compare to Other Forms?

Not all magnesium supplements work the same way in the body. The carrier molecule bound to the mineral determines how well it crosses your intestinal wall and what benefits it provides:

Supplement Facts

* Percent Daily Values (%DV) are based on a 2,000 calorie diet.
† Daily Value not established.

Other Ingredients:

Stearic acid, microcrystalline cellulose, acacia gum, magnesium stearate, silica, and modified cellulose gum.

Allergen Purity & Dietary Specifications:

Suitable for vegetarians. Non-GMO. Contains NO yeast, dairy, egg, gluten, corn, soy, or wheat. Free of sugar, starch, artificial preservatives, artificial flavors, colors, and synthetic fragrances.

Suggested Use, Dosing Strategy & Safety Guidelines

Recommended Dosage:

Take 1 to 3 tablets daily with meals, or as directed by your healthcare practitioner.

Pro Tip: Because malic acid supports daytime energy production, magnesium malate is best taken with breakfast and lunch. Splitting your intake (e.g., 1 tablet with breakfast and 1 to 2 tablets with lunch) optimizes gut absorption and ensures sustained mineral availability throughout your waking hours.

• Pregnancy & Nursing: If you are pregnant, planning to become pregnant, or breastfeeding, consult your physician before using this supplement.

• Renal Function: Individuals with kidney disease, impaired renal clearance, or severe heart blocks should only supplement with magnesium under direct medical supervision.

• Medication Timing: Take magnesium supplements at least 2 hours apart from bisphosphonates, tetracyclines, and quinolone antibiotics to avoid reducing medication absorption.

Storage: Store tightly capped in a cool, dry place. Do not use if either tamper-evident seal is broken or missing. Keep out of reach of children.

Frequently Asked Questions (FAQ)

What is the difference between magnesium malate and magnesium glycinate?

While both are highly absorbable organic forms, they serve different daily goals. Magnesium malate binds magnesium to malic acid, which fuels the Krebs cycle to produce cellular ATP, making it ideal for combating physical fatigue, post-exercise soreness, and daytime stiffness. Magnesium glycinate binds magnesium to the calming neurotransmitter glycine, making it better suited for nighttime relaxation and supporting deep sleep.

Will Source Naturals Magnesium Malate cause an upset stomach or diarrhea?

Magnesium malate has very low gastrointestinal side effects compared to poorly absorbed forms like magnesium oxide or high-dose magnesium citrate. Because the malate chelate is efficiently absorbed into the bloodstream, far less unabsorbed mineral stays behind in the colon to draw water and trigger an osmotic laxative effect.

What is the best time of day to take magnesium malate?

Because malic acid actively participates in cellular energy creation, most individuals experience the best results by taking it in the morning with breakfast or early afternoon with lunch. It generally does not cause restlessness, but taking it earlier in the day complements your body's natural circadian energy cycles.

How much elemental magnesium is in each Source Naturals tablet?

Each individual 1,250 mg tablet provides approximately 142 mg of bioavailable elemental magnesium alongside 833 mg of malic acid. A full 3-tablet serving supplies 425 mg of elemental magnesium (101% of the daily value) and 2,500 mg of total malic acid.

Can magnesium malate help with tight muscles and leg cramps?

Yes. Muscle fibers contract when stimulated by calcium and relax when balanced by magnesium. If your tissues lack sufficient magnesium, calcium remains in the muscle cells, causing persistent contractions, spasms, and twitching. Supplementing with bioavailable magnesium malate helps flush out excess intracellular calcium, allowing tense muscle bundles to relax naturally.

How long does it take to feel the benefits of magnesium malate?

Acute cellular uptake begins within hours of your first dose. However, restoring depleted intracellular mineral stores and easing chronic muscle tightness typically takes between 2 to 4 weeks of consistent daily supplementation alongside balanced meals.
