Factors to Consider When Choosing Magnesium Supplements

Form of Magnesium Used

The form of magnesium used to make the supplement is the first factor you should consider when choosing a magnesium supplement. The best magnesium supplements vary and can be made from various forms of magnesium. The most common is magnesium citrate, magnesium taurate, magnesium chloride, magnesium lactate, and magnesium oxides.

Magnesium in the chloride, lactate, citrate and taurate forms are absorbed much faster than magnesium oxides. They are also less likely to cause bowel movements. On the other hand, magnesium oxides have a laxative effect, and they can therefore affect or clear the bowels. Most supplements use magnesium oxides because it is the cheapest form of magnesium.

Despite that, other supplements use forms like magnesium citrate, which absorbs easily and quickly into the body. Additionally, some forms of magnesium contain small amounts of elemental magnesium. Therefore, they require larger magnesium capsules or larger dosages to reach the desired amount of elemental magnesium. Such forms of magnesium include magnesium chelate. 

For instance, if you purchase a bottle of supplements with 180 magnesium tablets containing magnesium chelate and you require a daily dose of three tablets, then your bottle will last for around two months. In the long run, this will end up being a bit costly or a waste of money when you can get a supplement with enough magnesium in one capsule per day. 

Dosage or Daily Intake of the Supplement

Before choosing a magnesium supplement, you need to know the dosage of the supplement. Many supplements have different dosages. Also, dosages differ with people and therefore breastfeeding mothers, pregnant women, and people with underlying conditions have their prescribed dosages that a health professional must check.

 

Therefore, if you are expected to take 300mg of magnesium daily, you cannot take a supplement with a 440mg dosage. It is significantly higher than the prescribed or recommended dose. It can cause vomiting, muscle cramps, nausea, stomach upsets, insomnia, among other side effects. To prevent such side effects, you have to consult with a healthcare professional before you start taking such supplements. The healthcare professional will give you an insight into how much magnesium you have to use.

Product Quality

When choosing a magnesium supplement, you should look at whether their product is of good quality by looking at if the brand has a third-party certification. Some supplements are taken for third-party testing to ensure that their products are free from heavy metals and of good quality.

There is also a GMP certification awarded to different supplements to show that the manufacturing is according to the required process for safety and quality. 

Additional Products

Before purchasing a magnesium supplement, you should also consider the additional products put in the magnesium supplements, including artificial flavours. It is preferable to consider supplements without any artificial flavours. Additionally, consider your allergic reactions to the products used. 

For instance, if you are allergic to dairy, you should go for a dairy-free supplement. There are many different types of magnesium supplements. Some supplements are either gluten-free, dairy-free, free from nuts, GMO-free, soy-free, and lactose-free. Some supplement diets such as keto diets, halal diets, and kosher diets. 

Depending on the type of diet you are on, you can choose the supplement best suited for you. 

What Is the Most Appropriate Magnesium Dosage?

Well, the amount of magnesium that you should be taking in a day depends on the levels of magnesium in your body. However, the most appropriate dosage for adults is about 350 milligrams to 450 milligrams in a day.

Moreover, if your body doesn’t have adequate magnesium, a high dosage might be ideal for you. Apart from that, the daily dosage might depend on what you are trying to achieve in the end. For instance, the magnesium dosage required to make your muscles relax might be different from the dosage needed to deal with high blood pressure.

While some magnesium supplements might have information that gives you insight into the daily dosage, it is advisable to visit a doctor or a medic before you start your daily dosage. Not to mention, medics can take various tests, which might help you know if you are healthy or not. The doctor can use such information to determine the most suitable dosage for you, depending on your health status.

Which Is Better Between Liquid Supplements and Tablet Supplements?

Well, liquid supplements are flavoured and might have a superb taste as compared to magnesium tablets. However, everything boils down to your personal preferences. For instance, magnesium tablets can be carried easily from one point to another as compared to magnesium liquid form supplements.

Apart from that, magnesium is also available in powder form. The powder can be mixed with a certain amount of water, making it easier for you to take your daily dosage. If you are looking for a method that works instantly, a magnesium spray might be suitable for you. Magnesium sprays take a short period of time to get absorbed into the body and are effective in boosting normal muscle function.

Furthermore, magnesium supplements are also available in efflorescent tablets. Unlike the normal magnesium tablets, efflorescence tablets have to be mixed with water. They can dissolve in water, making it easier for you to take your daily magnesium dosage to support healthy bones and boost your energy levels. Magnesium flakes might also be ideal for improving your general health. You can use the magnesium flakes while you are bathing.
