Magnesium Citrate Powder, Citrus Berry by Thorne delivers highly bioavailable Magnesium Citrate in a pleasant citrus berry flavored powder to support muscle relaxation, healthy sleep architecture, nervous system function, and cardiovascular function in one daily scoop.
Key Benefits of Magnesium Citrate
-
Magnesium Citrate
- One of the most bioavailable forms of magnesium, combining magnesium with citric acid to enhance intestinal absorption compared to less soluble forms such as magnesium oxide, supporting efficient delivery of this essential mineral to tissues throughout the body.
-
Muscle Relaxation & Recovery
- Magnesium supports healthy muscle function by regulating calcium-mediated muscle contraction and relaxation, promoting recovery from physical activity and maintaining comfortable muscle tone throughout the day.
-
Nervous System Support
- Magnesium supports healthy GABA activity, the primary inhibitory neurotransmitter in the central nervous system, promoting a calm and balanced nervous system response and maintaining neurological function.
-
Sleep Quality Support
- Magnesium supports the nervous system's ability to downregulate at night, promotes healthy sleep onset, and maintains healthy sleep architecture, making it a foundational nutrient for adults with sleep quality concerns.
-
Cardiovascular Function
- Magnesium supports healthy vascular smooth muscle relaxation, promotes healthy blood pressure already within normal range, and maintains cardiovascular function through its role in cardiac muscle physiology and electrolyte balance.
-
Energy Metabolism
- Magnesium is a required cofactor for ATP synthesis, the primary energy currency of the cell, supporting cellular energy production and maintaining metabolic efficiency across all organ systems.
-
Enzymatic Cofactor Activity
- Magnesium participates in over 300 enzymatic reactions in the body, including those involved in DNA synthesis, protein production, and glucose metabolism, making it one of the most broadly essential minerals in human physiology.
-
Powder Format for Flexible Dosing
- A powder format allows for flexible serving adjustments and easy mixing into water or beverages, supporting consistent daily magnesium intake without the need for multiple capsules.
Magnesium deficiency is among the most prevalent micronutrient insufficiencies in adults, with estimates suggesting that a significant portion of the population does not meet the recommended daily intake through diet alone. The form of magnesium used in supplementation matters considerably for absorption and tolerability. Magnesium Citrate is well-established as a highly bioavailable form that is efficiently absorbed in the gastrointestinal tract and well-tolerated at clinically relevant doses. Thorne's powder format provides the additional advantage of flexible dosing and rapid dissolution, making it practical for individuals who prefer not to take multiple capsules or who want to incorporate magnesium into their daily beverage routine. The Citrus Berry flavor supports consistent daily adherence without the need for flavoring agents that compromise ingredient quality.

Frequently Asked Questions
Who is Magnesium Citrate Powder intended for?
Magnesium Citrate Powder is formulated for adults looking to support healthy muscle function, sleep quality, nervous system balance, and cardiovascular function through daily magnesium supplementation. It is particularly relevant for individuals with suboptimal dietary magnesium intake, those with active lifestyles, and adults experiencing muscle tension, sleep irregularity, or stress-related nervous system imbalance. It is not intended to diagnose, treat, cure, or prevent any disease.
How should I take Magnesium Citrate Powder?
The recommended serving is 1 scoop once per day, mixed into water or a beverage of your choice. Many users prefer taking it in the evening, as magnesium's support for nervous system relaxation and sleep quality makes it well-suited for a pre-sleep routine. It can also be taken at any time of day to support muscle function and energy metabolism.
Magnesium bioavailability varies significantly by form. Magnesium oxide, one of the most commonly used forms in lower-cost supplements, has relatively poor solubility and absorption in the gastrointestinal tract. Magnesium Citrate, by contrast, is highly soluble and well-absorbed, making it a more efficient delivery form for achieving meaningful increases in serum and tissue magnesium levels. For individuals seeking to address suboptimal magnesium status, the form of magnesium used in supplementation is an important consideration.
How does magnesium support sleep quality?
Magnesium supports the activity of GABA, the primary inhibitory neurotransmitter in the central nervous system that promotes a calm, relaxed state conducive to sleep. It also supports the regulation of the hypothalamic-pituitary-adrenal (HPA) axis, which governs the stress response, and helps maintain healthy melatonin production pathways. Together, these mechanisms support healthy sleep onset and sleep architecture, making magnesium one of the most well-supported nutritional interventions for sleep quality.
Can I take Magnesium Citrate Powder if I am already taking a multivitamin that contains magnesium?
Individuals taking a multivitamin or other supplements that contain magnesium should review their total daily magnesium intake when adding this product to their routine. The tolerable upper intake level for supplemental magnesium in adults is 350mg per day from supplements, above which gastrointestinal effects such as loose stools may occur in some individuals. Consulting a qualified healthcare provider is recommended if you are combining multiple magnesium-containing products.
Is this product suitable for individuals with kidney conditions?
Individuals with kidney conditions should consult a qualified healthcare provider before using magnesium supplements, as impaired kidney function can affect the body's ability to excrete excess magnesium. This is an important safety consideration for this population and not a product-specific limitation.
How long before I notice results?
Individual responses vary based on baseline magnesium status and the specific outcomes being supported. Some users report noticing improvements in muscle relaxation and sleep quality within the first one to two weeks of consistent use. Benefits related to energy metabolism and long-term cardiovascular function are best assessed over 4 to 8 weeks of daily supplementation.
