Curated, not stocked.
Pure Encapsulations has earned its place in our dispensary because of its no-filler formulation philosophy — what's on the label is what's in the product. Magnesium citrate is the form our clinicians reach for when bioavailability matters. The powder format is particularly useful when a patient needs a gradual titration or simply won't tolerate capsules. It is a straightforward, well-evidenced mineral supplement for a common and often under-diagnosed deficiency.
About this product
Magnesium Powder
Pure Encapsulations Magnesium Powder is a magnesium citrate supplement in loose powder form. Magnesium citrate is a well-absorbed organic form of magnesium, generally regarded as more bioavailable than inorganic options such as magnesium oxide. The mineral is involved in over 300 enzymatic processes in the body, including muscle contraction and relaxation, nerve transmission, and the regulation of sleep-wake cycles.
This format suits people who prefer to avoid capsules, need flexible dose adjustments, or find powder easier to incorporate into a daily routine — stirred into water, a smoothie, or a warm drink before bed. It is a practical choice for those with confirmed low magnesium, athletes in heavy training, individuals with disrupted sleep, or anyone whose diet is consistently low in magnesium-rich foods.
Magnesium is also commonly used alongside other sleep or recovery protocols, and the powder format makes it straightforward to titrate up or down depending on tolerance and individual response.
Pure Encapsulations is a professional-grade supplement brand with a longstanding reputation in clinical settings for clean, minimally formulated products. This single-ingredient powder reflects that ethos: magnesium citrate and nothing extraneous. For those who have had low magnesium confirmed via blood test, or whose clinician has recommended supplementation, this is a considered and practical option.

How to use
Mix 1 teaspoon into water or a drink of your choice once daily. Many people find it most useful taken in the evening, as magnesium is often used to support wind-down and sleep. Take with food if you find it causes digestive discomfort on an empty stomach.

Common questions
Frequently asked
How does magnesium citrate differ from other forms of magnesium?
Magnesium citrate is an organic salt of magnesium that is generally considered more bioavailable than inorganic forms like magnesium oxide. It is a common first choice when the goal is reliable absorption. Other forms such as magnesium glycinate are sometimes preferred specifically for sleep or if citrate causes loose stools.
Can this help with sleep?
Magnesium is studied for its role in supporting sleep quality, likely through its involvement in the regulation of the nervous system and melatonin pathways. It is not a sedative, but many people report improved sleep onset and quality when correcting a deficiency. Results vary and are most pronounced in those who are genuinely low in magnesium.
Is this suitable if I have a sensitive stomach?
Magnesium citrate can have a mild laxative effect at higher doses, which is worth noting if your digestion is sensitive. Taking it with food may reduce this. If it causes persistent discomfort, speak to your clinician about whether a different form — such as magnesium glycinate — might suit you better.
Who should avoid magnesium supplementation?
People with kidney disease or impaired renal function should not supplement magnesium without medical supervision, as the kidneys regulate magnesium excretion. Magnesium can also interact with certain medications, including some antibiotics and bisphosphonates. Check with your GP or pharmacist if you are on regular medication.
How long before I notice a difference?
This depends on how deficient you are to begin with. Some people notice improvements in sleep or muscle tension within one to two weeks; for others it takes longer. A blood test before and after supplementation is the most reliable way to track whether your levels are responding.
