Description
Magnesium is an essential mineral that fulfils numerous functions in the human body, such as supporting muscle function, nerve transmission and regulating energy metabolism. There are several different magnesium compounds that are used for different applications depending on their specific properties. Of these, magnesium L-threonate, magnesium taurate and magnesium bisglycinate are particularly interesting. They each offer unique benefits in terms of bioavailability and action in the body. Here is a detailed overview of these three forms of magnesium, as supported by scientific studies.
Magnesium L-threonate
Magnesium L-threonate is a special form of magnesium that is created by binding it to L-threonate, a metabolite of vitamin C. This compound is being researched for cognitive purposes due to its ability to cross the blood-brain barrier. Magnesium L-threonate has been shown to efficiently increase magnesium concentrations in the brain, which could potentially support brain function and promote neuronal health.
A much-cited 2010 study by MIT researchers showed that this form of magnesium improved learning and memory in rats. It was found that increasing magnesium levels in the brain with magnesium L-threonate promotes synaptic plasticity, which is crucial for memory (DSpace). These findings have generated a great deal of interest in the use of this form of magnesium as a dietary supplement, particularly in the area of cognitive support.
Magnesium taurate
Magnesium taurate is a compound of magnesium and the amino acid taurine. This form of magnesium is often studied for its potential positive effects on the cardiovascular system. Taurine is a non-proteinogenic amino acid involved in many physiological processes, including regulating electrolyte balance and supporting cardiovascular health.
A 2016 study in rats examined the combination of taurine and magnesium and showed that this compound could potentially support heart health by affecting blood pressure regulation (RSC Publishing).
In addition, magnesium taurate is known to have a calming effect on the nervous system, making it a popular choice for people seeking general nervous system support.
Magnesium Bisglycinate
Magnesium Bisglycinate is a chelated form of magnesium, where the magnesium is bound to the amino acid glycine. This compound is characterised by high bioavailability, meaning it is particularly well absorbed by the body. Magnesium bisglycinate is also known for its gentle effect on the digestive system, making it a preferred choice for people who take magnesium supplements without experiencing gastrointestinal discomfort.
A 2014 study compared various magnesium compounds and found that magnesium bisglycinate is one of the most efficient forms in terms of absorption in the body (Oxford Academic).
Glycine itself has a calming effect, making magnesium bisglycinate supplements attractive to people seeking a relaxing effect on the nervous system.
Similarities and differences
All three magnesium compounds – magnesium L-threonate, magnesium taurate and magnesium bisglycinate – share the general health benefits of magnesium, but differ in their specific effects and bioavailability:
- Magnesium L-threonate: is valued primarily for its potential benefits for brain function and cognitive support. It effectively reaches the central nervous system and can support neuronal health.
- Magnesium taurate: is used primarily for its potential benefits for the cardiovascular system and its calming effect on the nervous system. The combination of magnesium and taurine could have a positive effect on the heart and nerves.
- Magnesium bisglycinate: is characterised by its high bioavailability and gentle effect on the digestive system. It is often used as a well-tolerated form of magnesium that also has relaxing properties.
Research and studies
- Magnesium L-threonate: A study by MIT scientists showed that this form of magnesium improved brain function in rats by increasing synaptic density in the hippocampus, an area important for memory (DSpace).
- Magnesium taurate: A 2016 study examined how magnesium taurate can support heart function in animals. The results suggest that the compound could have a positive effect on blood pressure and support the cardiovascular system (RSC Publishing).
- Magnesium bisglycinate: A 2014 study compared different forms of magnesium and demonstrated that magnesium bisglycinate is one of the most bioavailable and well-tolerated forms of magnesium (Oxford Academic).
Magnesium L-threonate, magnesium taurate and magnesium bisglycinate are three high-quality forms of magnesium that differ in their use and mode of action. While magnesium L-threonate is used primarily to support cognitive function, magnesium taurate focuses on the cardiovascular system, and magnesium bisglycinate is known for its high bioavailability and tolerability. Each form offers specific advantages, so the right choice depends on individual needs and goals. It is advisable to consider your personal health situation when choosing a magnesium supplement and to seek expert advice if necessary.

Science Behind Safe Listening Levels for Children’s Headphones
In the world of audio devices, ensuring safe listening levels is paramount, especially when it comes to children’s headphones. The general consensus among experts is that an environmental noise level of 85 dBA is considered reasonably safe for an hour of listening. This threshold helps protect sensitive ears from potential hearing damage. Many children’s headphones claim to limit the maximum volume to this level, but verifying these claims requires careful testing and analysis.
To truly understand how these headphones measure up, we embarked on a comprehensive evaluation of their volume-limiting functions. Our journey began with consulting hearing experts, who provided valuable insights into the testing processes. One crucial element of our approach was the use of pink noise—a common test signal that mimics the content of music. This noise sounds similar to the white noise you might hear on an old analog-tuner FM radio, but with less hiss.
The Role of Pink Noise in Audio Testing
Pink noise plays a vital role in audio testing because it offers a repeatable and reliable method for measuring sound levels. We used pink noise with A-weighting (dBA), which removes frequencies below about 500 Hz, to ensure our measurements closely resembled real-world conditions. According to the experts we consulted, low frequencies have a negligible effect on hearing loss, making pink noise a suitable tool for our tests.
However, pink noise is only a simulation. To add a real-world evaluation, we used a popular song to measure how loud these headphones could get. This approach allowed us to assess the headphones’ performance under conditions more akin to everyday use. Our tests revealed that some headphones exceeded the 85 dBA threshold, highlighting the importance of accurate testing for determining safe listening levels.
Testing Methodologies and Calibration
Our testing process involved attaching headphones to a GRAS 43AG ear and cheek simulator, which we also use for active-noise-cancellation testing and frequency response measurements. We utilized a “diffuse-field calibration curve” to ensure our measurements were comparable to the 85 dBA free-air measurement. This calibration involved playing pink noise through a speaker and measuring it with specialized equipment to create a correction curve.
To achieve accurate results, we calibrated the 43AG’s level using a Reed SC-05 calibrator and connected it to an M-Audio Mobile Pre USB interface and a laptop running Room EQ Wizard. This setup allowed us to gather extensive data and identify headphones that met our safety criteria.
Challenges and Considerations in Headphone Testing
Despite our rigorous testing methodologies, headphone measurements have inherent inconsistencies. Small differences in the fit of headphones on the ear and cheek simulator can affect results, similar to how adjusting headphones on your ears changes the sound. To mitigate this, we ensured a good fit for each pair of headphones on the simulator and used light pressure from the 43AG’s clamping mechanism.
Recognizing the potential for measurement inaccuracies, we decided to set our pass/fail point at 88 dBA for pink noise tests and 90 dBA for music Leq tests. This decision takes into account the variability in audio content and measurement error, providing a reasonable margin for ensuring safe listening levels.
Insights from Testing Results
Our testing revealed a wide range of volume levels among children’s headphones. In our original tests, up to one-third of the headphones exceeded 85 dBA with pink noise, and nearly half surpassed this level with actual music. The disparity in maximum volumes, sometimes reaching a 32-decibel difference, underscores the need for stringent testing and quality control among manufacturers.
These findings emphasize the importance of selecting headphones that prioritize safety, especially for young listeners.
