Magnesium-rich foods include leafy greens, nuts, seeds, beans, and avocado
Magnesium is a crucial mineral for the body's functions. It helps maintain normal blood pressure, strong bones, and a steady heart rhythm. It also controls blood sugar levels and produces energy. Every cell in the body contains magnesium and needs it to function.
Seeds, such as chia seeds, are also a great way to get more magnesium in your diet. Beans, including black beans, edamame, and lima beans, are also high in magnesium and provide several other nutritional benefits. Avocados are another magnesium-rich food that can reduce inflammation, improve cholesterol levels, and increase feelings of fullness after meals.
Incorporating these foods into your diet can help ensure you're getting enough magnesium, which is essential for the body and brain. Eating whole foods is always best, as magnesium can be lost during refinement and processing. While supplements are an option, it's important to consult a healthcare professional first, as excessive intake can have adverse effects.

Magnesium supplements may cause nausea, cramps, and diarrhoea
Magnesium is an important mineral that is crucial for the body's functions. It helps keep blood pressure normal, bones strong, and the heart rhythm steady. It also controls blood sugar levels and makes protein and DNA. While it is generally safe to get high levels of magnesium from food, adding large amounts of supplements to your diet can have side effects and be dangerous.
Magnesium supplements may cause gastrointestinal issues like nausea, cramps, and diarrhoea. This is because of magnesium's effect on the gut, as it attracts water into the intestines, leading to increased bowel movements. The more magnesium you take, the higher your chances of experiencing this side effect. Magnesium oxide and magnesium citrate are two forms of magnesium that may be more likely to cause diarrhoea. This is because magnesium oxide works as an osmotic laxative, drawing liquid into the colon and stool, giving the stool more bulk.
If you suspect that your magnesium supplements are causing these side effects, it is recommended that you try a lower dose. It is also important to speak with a healthcare provider before starting any new medications, including supplements, to ensure that they do not interfere with any other medicines you may be taking.
It is worth noting that magnesium supplements are not the only way to increase your magnesium intake. Magnesium-rich foods such as spinach, chia seeds, peanut butter, and avocados can be great additions to your diet and help you avoid the potential side effects of supplements.

Magnesium can help regulate blood sugar levels and boost athletic performance
Magnesium is an important mineral for your body and brain, and it is found throughout your body. It is involved in more than 600 reactions in your body, including regulating neurotransmitters, which are responsible for sending messages throughout your brain and nervous system.
Magnesium can help regulate blood sugar levels, especially for people with diabetes. Studies have shown that increasing magnesium intake through food or supplements may help people with diabetes improve their blood sugar regulation. For example, a 12-week study found that taking 300 mg of magnesium daily significantly lowered fasting blood sugar levels, as well as post-meal blood sugar levels, compared to taking a placebo pill. Additionally, people with type 2 diabetes often have lower blood levels of magnesium, and increasing magnesium levels could help lower the risk of developing insulin resistance and diabetes.
Magnesium is also crucial for boosting athletic performance. It is essential for muscle contractions and relaxation, and it supports optimal muscle performance, allowing athletes to push their limits and reach new heights. Magnesium also helps reduce muscle cramps and promotes tissue repair, leading to less downtime between workouts. Furthermore, magnesium plays a role in promoting restful sleep, which is an important component of recovery for athletes.
Magnesium-rich foods include leafy greens, nuts, seeds, beans, spinach, chia seeds, peanut butter, and avocados. However, it is important to note that only about 20-40% of magnesium from food is used in the body, and supplementation may be beneficial in some cases.

People with diabetes, intestinal disease, heart disease, or kidney disease should consult a doctor before taking magnesium
Magnesium is an essential nutrient for the brain and body. It helps regulate blood sugar, among other benefits. However, taking too much magnesium can pose certain health risks. Ingesting large amounts can lead to magnesium toxicity, which can be fatal. Symptoms of magnesium toxicity include nausea, vomiting, difficulty breathing, irregular heart rate, and cardiac arrest. Poor kidney function is a risk factor for magnesium toxicity due to the kidneys' inability to remove excess magnesium from the body.
People with diabetes often experience magnesium deficiency. This is because low levels of magnesium are associated with insulin resistance. Taking a magnesium supplement can increase blood magnesium levels and improve diabetes control. However, only a few small clinical trials have evaluated the benefits of supplemental magnesium for diabetes, and more research is needed to determine the best type of magnesium for glucose control.
Some studies have found a link between higher magnesium intake and a reduced risk of developing metabolic syndrome, which increases the risk of heart disease. Increasing magnesium intake has also been linked to a reduced risk of death related to heart disease. However, other studies have found no benefit in preventing heart disease.
Magnesium is crucial for maintaining intestinal magnesium absorption and renal excretion to achieve magnesium balance. The kidney plays a vital role in magnesium homeostasis, and this ability deteriorates when renal function declines significantly. In moderate chronic kidney disease, increases in the fractional excretion of magnesium compensate for the loss of glomerular filtration rate to maintain normal serum magnesium levels. However, in more advanced stages of chronic kidney disease, this compensatory mechanism fails, and hypermagnesaemia develops.
If you have diabetes, intestinal disease, heart disease, or kidney disease, it is important to consult a doctor before taking magnesium supplements to ensure they are right for you and to avoid potential health risks.

Magnesium may interfere with the absorption of certain medications
Magnesium is an important mineral for your body and brain. It is found throughout the body and is involved in more than 600 biochemical reactions. While it is safe to get high levels of magnesium naturally from food, adding large amounts of supplements to your diet can be dangerous.
Magnesium supplements may interfere with the absorption of certain medications, reducing their effectiveness. This is because magnesium and drugs use the same transport and metabolism pathways in the body for absorption, metabolism, and elimination.
For example, magnesium can interfere with the absorption of antibiotics, making it harder for your body to absorb and process them properly. This could mean that your antibiotic treatment is less effective. Similarly, magnesium supplements can interfere with how well your body absorbs bisphosphonate medications, which are used to strengthen bones and reduce the risk of fractures in people with osteoporosis.
Magnesium can also increase the absorption of sulfonylureas, a class of diabetes medications, potentially magnifying their effects and leading to low blood sugar (hypoglycemia). On the other hand, insulin and other diabetes medications can affect how your body processes magnesium, causing magnesium to leave your cells.
It is important to consult with a healthcare provider before taking magnesium supplements, especially if you are currently taking any medications.
