Magnesium l- threonate has come an decreasingly popular supplemental form of magnesium in recent times. frequently retailed as a way to enhance cognitive function and memory, magnesium l- threonate supplements have gained interest among consumers looking to optimize brain health. Still, with any rising fashionability of a salutary supplement, questions girding its safety are important to address. In this article, we’ll take an evidence-based look at the safety profile of magnesium l-threonate.
Understanding Magnesium L-Threonate
Magnesium is an essential mineral involved in over 300 biochemical responses in the body. It plays a crucial part in energy product, muscle and whim-whams function, blood glucose control, protein conflation, and further( 1). Magnesium insufficiency is fairly common, with some exploration estimating that up to half of the population in developed countries may not meet recommended diurnal inputs( 2).
Magnesium l- threonate is a form of magnesium that's clicked to l- threonate, a vitamin C metabolite. It's suitable to more effectively cross the blood- brain hedge compared to other forms like magnesium citrate or magnesium oxide( 3). Studies in creatures have shown increased magnesium situations in the brain after supplementation with magnesium l- threonate( 4). This unique capability to accumulate in the brain has led to interest in magnesium l- threonate for cognition and memory improvement.
Some preliminary research has suggested potential cognitive benefits with magnesium l-threonate supplementation. One study in mice found improved learning abilities and working memory with magnesium l-threonate (5). A small mortal airman study observed short- term enhancement in memory recall in aged grown-ups after taking magnesium l- threonate diurnal for a month( 6). still, larger scale clinical trials are still demanded.
Safety Profile of Magnesium L-Threonate
When evaluating the safety of any dietary supplement, it’s important to analyze data from clinical trials, reported side effects, and expert opinions. Here’s what the current evidence says about the safety of magnesium l-threonate powder:
- Clinical Trials: Human clinical trials published thus far have not reported any significant side effects or safety issues with magnesium l-threonate supplementation at doses up to 2,000 mg per day for adults (6,7). Mild gastrointestinal effects like diarrhea were occasionally noted. Studies in rodent models using very high doses also did not result in toxicity (4).
- Reported Side Effects: Reviews of consumer experiences online indicate that the most commonly reported side effect is mild diarrhea or laxative effects, especially when taking high doses (8). This is consistent with findings from clinical trials. There are few reports of other adverse reactions.
- Expert Opinions: Health organizations like the NIH Office of Dietary Supplements consider magnesium supplements safe for most people at recommended dosages (9). Toxicity risk is higher with excessive intake from supplements or interactions with medications. Experts advise staying below the Tolerable Upper Intake Level of 350 mg per day for supplemental magnesium (10).
- Regulatory Status: Magnesium l-threonate has self-affirmed generally recognized as safe (GRAS) status in the United States, meaning it meets FDA safety criteria for use in food and supplements (11). No special warnings or restrictions have been issued. Reputable brands adhere to good manufacturing practices.
Common Questions About Magnesium L-Threonate Safety
There are also some frequently asked questions about the safety profile of magnesium l-threonate in particular:
Does magnesium l-threonate have side effects?
The most common side effect is mild gastrointestinal discomfort, especially at high doses. Diarrhea and laxative effects are most frequently reported. Magnesium can also interact with certain medications, so consulting a doctor is important if taking other prescriptions.
Is magnesium l-threonate the best form of magnesium?
Experts consider various forms like magnesium glycinate and magnesium citrate highly bioavailable. Magnesium l-threonate appears unique in its ability to cross the blood-brain barrier but other forms have advantages too. It may come down to individual factors and desired benefits.
What does magnesium l-threonate do to the brain?
Research indicates magnesium l-threonate can accumulate in the brain more readily than other forms. This may potentially promote neuron health and synaptic plasticity through increased magnesium levels, but larger clinical studies are still needed.
Does magnesium l-threonate reverse brain aging?
There is no evidence that magnesium l-threonate can reverse brain aging. Some early research shows potential short-term cognitive benefits, but claims of reversing brain aging are unsupported. Maintaining normal magnesium status may help support general brain health as we age.
Does magnesium l-threonate make you sleep?
Magnesium has a relaxing effect and aids sleep, but there’s no research specifically showing magnesium l-threonate improves sleep quality. Any supplemental magnesium taken in the evening may help sleep by meeting magnesium needs.
Does magnesium l-threonate work immediately?
Research has focused on longer-term supplementation for cognitive benefits. Acute benefits immediately after taking magnesium l-threonate haven’t been established. Changes in brain magnesium levels likely take time. Always follow dosage directions.
Conclusion: A Generally Safe Supplement, but More Research Needed
In conclusion, current evidence suggests magnesium l-threonate is likely safe for most people when used appropriately. Mild gastrointestinal side effects are possible, especially at high doses. There is no evidence of serious adverse effects. However, the long-term safety profile needs more research as widespread use is relatively recent. As with any supplement, it’s wise to consult your healthcare provider before use.
For individuals looking to optimize brain health and cognition as they age, magnesium l-threonate appears promising but not miraculous based on early research. Maintaining adequate total magnesium intake from a balanced diet and high-quality supplementation as needed may support brain function over the long-term. Magnesium l-threonate is likely one safe option in that toolkit, but more rigorous clinical trials are still needed to verify effectiveness and ideal dosing strategies.
