Comparison of Magnesium Glycinate and Magnesium L-Threonate
In comparing magnesium glycinate and magnesium L-threonate, I focus on their distinctive chemical properties, targeted health outcomes, and the potential side effects to consider.
Chemical Properties and Effects
Magnesium Glycinate is a compound of magnesium and the amino acid glycine. This form is recognized for its high bioavailability, meaning I can expect a greater proportion of magnesium to be absorbed into my bloodstream. The presence of glycine is believed to confer a calming effect, making it beneficial for individuals seeking to manage stress and improve sleep.
Magnesium L-Threonate, on the other hand, includes magnesium and the metabolite of vitamin C known as L-threonate. A notable property of magnesium L-threonate is its ability to cross the blood-brain barrier, which points to enhanced magnesium uptake in the brain compared to other forms. This suggests potentially greater benefits for cognitive function and brain health.
Targeted Health Outcomes
In terms of targeted health outcomes, magnesium glycinate is often recommended for those with deficiencies as it can effectively raise magnesium levels in the body. It’s a go-to recommendation for people experiencing chronic stress, insomnia, or muscle cramps because of the associated benefits of glycine.
Magnesium L-threonate targets cognitive health by increasing the density of synapses, which are critical for learning and memory. As it can influence magnesium levels within the brain, there’s ongoing research into its effects on conditions like age-related cognitive decline and dementia.
Potential Side Effects and Considerations
Both forms of magnesium have a good safety profile, but there are different side effects and considerations to be aware of. Magnesium glycinate is less likely to cause a laxative effect, a common issue with other magnesium supplements, due to the presence of glycine. Typically, the recommended dosage for magnesium glycinate is between 200 mg to 400 mg daily.
Magnesium L-threonate can sometimes result in headaches, dizziness, or drowsiness, especially if I take a higher than recommended dosage. The typical recommended dosage is up to 2000 mg of magnesium L-threonate, which provides around 144 mg of elemental magnesium. It’s important to start with a lower dose and increase gradually to mitigate potential side effects.
Recommended Dosage and Safety
When discussing magnesium threonate and glycinate, I will focus on their recommended dosages and safety profiles, which are crucial factors for anyone considering these supplements.
Daily Intake Recommendations
For magnesium threonate, I generally recommend following the manufacturer’s guidelines due to the lack of established Recommended Dietary Allowances (RDA). However, as a guideline, many products suggest a daily intake of around 1,000 to 2,000 mg of magnesium threonate, which typically translates to about 144 to 288 mg of elemental magnesium.
On the other hand, for magnesium glycinate, the recommended dietary allowance varies depending on age and gender. To illustrate, here’s a table outlining the RDA for magnesium in general:
| Age & Gender | RDA for Magnesium |
| Adult men | 400-420 mg |
| Adult women | 310-320 mg |
| Pregnant women | 350-360 mg |
I note that magnesium glycinate is often dosed to provide a substantial portion of these amounts, usually around 100-350 mg of elemental magnesium per day.
Considerations for Different Populations
Those with kidney disease require special attention. It’s often advised for individuals with kidney impairments to avoid magnesium supplementation unless prescribed by a healthcare provider. This is because the kidneys play a central role in magnesium excretion, and impaired kidney function can lead to an accumulation and potential toxicity.
In terms of deficiency, symptoms like muscle cramps and heart irregularities can arise, indicating a need for increased magnesium intake. However, an overdose is possible with excessive supplement use, leading to side effects such as diarrhea, nausea, and abdominal cramps. More severe issues, like hypotension and bradycardia, are rare but possible with extreme amounts.
Safety is paramount, so I always advocate for consulting with a healthcare provider before taking supplements, especially for populations with particular considerations such as elderly individuals, pregnant women, those with chronic health conditions, or individuals already on medication.
