AOR AOR - Magnesium Potassium Aspartates, 120 vcaps

AOR Magnesium Potassium Aspartates - Contains true, fully-reacted nutrients in doses backed by clinical studies to deliver maximum relief from fatigue. Aspartate or aspartic acid is a naturally-occurring amino acid, which alongside magnesium, plays a role in the production of ATP, the body’s energy source. Potassium is an essential electrolyte involved in both electrical and cellular functions that assist in the regulation of the body’s acid-base balance and the proper functioning of nerve cells, which is essential for the transmission of neurochemical messages. Magnesium and potassium are known to cooperate in the body, with magnesium enhancing the cellular transport of potassium. Studies with this combination have involved over 3000 human subjects, and it was shown that 65-91% of chronic fatigue sufferers taking fully-reacted magnesium and potassium aspartates (500 mg of each, twice daily) experienced clear-cut alleviation of their symptoms within 5 to 10 days. Magnesium and potassium are also important electrolytes, and several studies have demonstrated the beneficial effects of magnesium and potassium aspartates on sports performance.

Why people keep reordering it

Highly absorbable forms: Chelated forms your body takes up, instead of oxide that mostly passes through.
Calm and recovery: Supports muscle relaxation, sleep quality and everyday stress resilience.
Gentle on digestion: Formulated to skip the laxative effect of cheaper magnesium.

Best suited to: someone with low-grade tiredness wanting an electrolyte-based approach, an athlete looking to support electrolyte balance around training, someone who wants a gentle, food-taken twice daily routine.

What the research supports

Each capsule provides 30 mg of magnesium and 50 mg of potassium, both as aspartate salts. Two capsules a day, and the 120-count bottle lasts two months.

Original studies used 500 mg of each aspartate, twice daily.

Fatigue (evidence: limited, from open-label human studies, observational): Magnesium and potassium aspartate are part of the citric acid cycle cells use to generate ATP energy. Older observational studies reported improvement in most fatigued subjects, but this work predates modern randomized-trial standards.
Exercise performance (evidence: limited, from open-label human studies, observational): The aspartate ion is thought to help shuttle metabolic byproducts out of working muscle during exertion. Studies on this combination and physical performance exist, but results are inconsistent and mostly from smaller, older trials.

Is it right for you

Worth it if

someone with low-grade tiredness wanting an electrolyte-based approach: The magnesium and potassium aspartate combination was studied specifically for fatigue symptoms rather than general nutrient gaps.
an athlete looking to support electrolyte balance around training: Potassium and magnesium aspartates have been studied together for effects on sports performance and cellular electrolyte transport.
someone who wants a gentle, food-taken twice daily routine: The 30 mg magnesium and 50 mg potassium per capsule dosing is mild enough to fit easily alongside meals without a large single hit.

Look elsewhere if

someone wanting magnesium for sleep or muscle relaxation at a therapeutic dose: Look for a magnesium glycinate or citrate product delivering 200 to 400 mg of elemental magnesium, since this one provides only 60 mg a day at the standard dose.
anyone on potassium-restricted advice or with kidney concerns: Potassium supplements, even at modest doses like the 100 mg elemental here, are worth discussing with a healthcare provider before starting.
someone trying to match the original fatigue research exactly: The studied protocol used roughly double this product's standard dose, so ask a practitioner whether a higher intake fits your situation.

What to expect

If it is going to help with tiredness, most of the original research showed improvement within 5 to 10 days at their higher dose, so give it at least a week or two of consistent use with food. This is not a stimulant and there is no immediate energy jolt to notice.

How it compares

Compared with magnesium citrate or glycinate alone: This product pairs magnesium with potassium aspartate specifically for the fatigue and electrolyte research behind the combination, not just magnesium repletion. The tradeoff: You get far less elemental magnesium per dose than a dedicated magnesium product, so it is not a substitute if magnesium alone is your goal.
Compared with a potassium chloride electrolyte supplement: The aspartate form here was the specific salt used in the fatigue studies referenced, rather than a generic electrolyte replacement. The tradeoff: At 50 mg elemental potassium per capsule, it delivers far less potassium than typical electrolyte drinks or salts aimed at hydration.
