Magnesium is an essential mineral that helps support over 300 bodily functions, including muscle and nerve function, blood pressure regulation, and energy production. But most people don't get enough magnesium from their diets.

Introducing Sealions' premium selection of magnesium supplements, designed to support your overall health and vitality. Whether you're an athlete looking for muscle recovery, someone struggling with sleep issues, or simply looking to promote heart health and reduce stress, our magnesium supplements have got you covered.

Backed by scientific research and crafted with utmost care, these supplements are the perfect addition to your daily wellness routine. Say goodbye to magnesium deficiencies and embrace a healthier, more energised you.

What is magnesium?

Magnesium is a mineral that's essential for many bodily functions, participating in over 300 enzymatic reactions, making it a true powerhouse of health benefits. This remarkable mineral is involved in a diverse range of processes, ranging from supporting muscle and nerve function, to regulating blood pressure and facilitating energy production. Its presence is crucial for maintaining our overall well-being, making it an indispensable component of a balanced and healthy lifestyle.

However, since our bodies cannot synthesise (make) magnesium on their own, we rely on external sources to meet our daily requirements. Ensuring adequate magnesium intake through diet or supplementation is essential for fostering a thriving and energised body, allowing us to lead healthier and more fulfilling lives.

What are the signs of magnesium deficiency?

Not having enough magnesium in your body can cause various problems. You might feel muscle cramps, get tired easily, or have an irregular heartbeat. Your mood could swing a lot, and you might feel anxious.

You might also experience tingling or numbness in your body. Low magnesium can make your bones weak and increase the risk of fractures. Your blood pressure might go up, and you could have trouble sleeping or get frequent headaches. It might be hard to concentrate and think clearly.

If you notice any of these signs, it could mean you have low magnesium levels. It's important to talk to a doctor to find out for sure. They can help you figure out the best way to get the right amount of magnesium for your body.

What are the benefits of magnesium supplements?

For individuals with low magnesium levels or those who have difficulty obtaining enough magnesium from their diet, supplements provide a convenient and effective solution. They help bridge the gap between the magnesium your body needs and the magnesium you may not be getting from food alone.

Some of the benefits of taking these supplements include:

  • Improved muscle and nerve function: Magnesium supports proper muscle contraction and relaxation, aiding in muscle function and reducing cramps or spasms. It also helps with nerve communication, ensuring messages travel smoothly throughout the body.
  • Reduced stress and anxiety: Magnesium has a calming effect on the nervous system, which can help reduce stress and anxiety levels. This can lead to a more relaxed and positive state of mind.
  • Lower blood pressure: Magnesium helps relax blood vessels, promoting better blood flow and circulation. This, in turn, can lead to lower blood pressure levels and support cardiovascular health.
  • Improved energy levels: As a vital component in energy metabolism, magnesium contributes to the production and storage of energy in our cells. This can result in improved energy levels and reduced fatigue.
  • Stronger healthy bones: Magnesium works together with calcium and vitamin D to maintain strong and healthy bones. It aids in the absorption of calcium, which is essential for maintaining bone density and preventing osteoporosis.
  • Promotes better sleep: Magnesium supplements can aid in promoting better sleep quality. Its relaxing effects can help individuals fall asleep faster and enjoy a more restful night's sleep.
  • Supports heart health: Magnesium is beneficial for maintaining a regular heart rhythm and supporting cardiovascular health. By helping relax blood vessels, it can contribute to a healthier heart.

Incorporating magnesium supplements into your daily routine can be a valuable addition to supporting overall health and vitality. However, do consult with a healthcare professional to determine the right dosage for you and ensure it complements your individual health needs.

How much magnesium should I take?

The recommended daily allowance of magnesium varies based on age, sex, and life stage. In general, adult men need around 400-420 mg, while adult women require 310-360 mg of magnesium per day. However, some people may need more magnesium than this, depending on their individual needs. For example, people with certain health conditions, such as diabetes or heart disease, may need to take more magnesium. Pregnant and lactating women may also have higher requirements.

Here are some general guidelines for taking magnesium supplements:

  • Start with a low dose and gradually increase it until you find the dose that works best for you.
  • Take magnesium supplements with food to help prevent stomach upset.
  • If you experience stomach upset, try taking a different form of magnesium, such as magnesium citrate or magnesium glycinate.
  • Avoid taking magnesium supplements at the same time as other medications, as they may interact

How do magnesium supplements work?

Magnesium supplements work by providing your body with the magnesium it needs. When you take magnesium supplements, the mineral is absorbed into your bloodstream through your digestive system. Once in the bloodstream, magnesium travels throughout your body, reaching various tissues and cells. It then takes on its essential role as a cofactor for hundreds of enzymatic reactions.

Do follow the recommended dosage when you take magnesium supplements, and if you're concerned about taking supplements, consult with a healthcare professional before starting any supplementation regime. While magnesium supplements can offer significant benefits, excessive intake may lead to potential side effects.

Potential side effects

While magnesium supplements are generally safe for most individuals, excessive intake can lead to diarrhoea, nausea, and stomach cramps.

  • Diarrhoea: Consuming too much magnesium at once can lead to loose or watery stools. This is because excess magnesium can draw water into the intestines, resulting in gastrointestinal discomfort.
  • Nausea: Some individuals may experience feelings of queasiness or an upset stomach after taking magnesium supplements, especially if you take them on an empty stomach.
  • Stomach Cramps: Excessive magnesium intake can cause stomach cramps or abdominal pain, particularly if the body is not accustomed to high doses.
  • People with kidney problems should be cautious about taking high doses of magnesium, as it can potentially worsen their condition.

    Magnesium can interact with other medications

    Do bear in mind that magnesium supplements may interact with certain medications, such as antibiotics and diuretics. Inform your healthcare provider about all the medications and supplements you are taking to avoid any potential adverse effects.
