Best Magnesium Glycinate for Leg Cramps

Best Magnesium Glycinate for Leg Cramps

Magnesium is a very important nutrient for our body. A magnesium deficiency can cause problems in our bodily functions. 

It has been reported that, in the United States, about 50% of people are magnesium deficient. There are both minor and major implications for this, ranging from conditions such as fatigue, nausea, and leg cramps at night, to abnormal heart rhythms and seizures. 

Here, we will discuss everything that you need to know about magnesium glycinate, why it is important, as well as the best magnesium glycinate for leg cramps that you can find on the market today. 

What is Magnesium Glycinate? 

Magnesium is a vital nutrient that benefits the muscles, nerves, and bones. It can also help in regulating blood sugar levels, especially for those who are suffering from diabetes. 

Other benefits of magnesium include the reduction of symptoms related to anxiety, PMS, and irregular heartbeat. It has also been proven to reduce pain.  

Magnesium comes in many forms, with magnesium oxide being the most prevalent due to its affordability. However, this form of magnesium is not easily absorbed by the body. 

On the other hand, magnesium glycinate combines magnesium with glycine, which helps it get absorbed by the body faster, allowing you access to its full benefits. 

Other forms of magnesium include:

  • Magnesium citrate
  • Magnesium malate
  • Magnesium threonate
  • Magnesium taurate

Out of all these, magnesium glycinate is still considered as the superior form of magnesium due to its high bioavailability. It is also the form that has a lower risk of potential side effects.

Why Do You Need Magnesium Glycinate? 

Taking magnesium glycinate is good for maintaining a healthy gut. It helps in easing conditions such as constipation and indigestion. It has also been said to be able to improve sleep. 

As magnesium is also known for improving nerve function, magnesium glycinate can help in preventing and reducing seizures, especially for those suffering from eclampsia. It can also reduce incidences of leg cramps at night.  

Magnesium glycinate also helps those with irregular heartbeat, asthma, diabetes, osteoporosis, and certain cancers by managing the complications caused by these diseases and conditions. 

Those who have certain issues like liver or heart failure, as well as those who have diarrhea or have vomited can also benefit from magnesium glycinate as it can help replenish lost magnesium stores within the body. 

Other benefits of taking magnesium glycinate regularly include relieving the symptoms of PMS in women, reducing pain, helping treat some infections, and reducing birth-related complications for both the child and the mother. 

What is the Recommended Dosage for Magnesium Glycinate? 

The National Institutes of Health recommends anywhere between 30 to 420 milligrams of magnesium glycinate per day, depending on the person’s gender and age. 

Those who are pregnant or breastfeeding may be recommended higher levels of this mineral. 

However, it is still recommended to consult with your doctor so that they can check up on you to ensure that you are getting the right daily dosage.  

The recommended daily magnesium intake for relatively healthy people is as follows:

  • Up to 30 milligrams for babies up to 6 months old
  • From 75 to 240 milligrams for infants to children up to 13 years old
  • Up to 410 milligrams for teenage boys
  • Up to 360 milligrams for teenage girls
  • Up to 420 milligrams for adult males
  • Up to 320 milligrams for adult females
  • From 310 to 400 milligrams for pregnant and breastfeeding women

What are the Side Effects of Magnesium Glycinate 

Before taking magnesium glycinate for leg cramps at night, to help treat some conditions, or just for general health, it is recommended to consult with a medical professional. 

The reason for this is that there are possible side effects as well as risks involved when taking this as a supplement. 

Possible side effects would include diarrhea, stomach cramps, upset stomach, some electrolyte imbalances, irritability, and vomiting, among others. 

It is also recommended to seek medical advice if you have diabetes or any liver, heart, or kidney-related issues before taking magnesium glycinate. 

Those with high blood pressure or taking medications should seek permission from a doctor first, as well. This is because some medications and magnesium can interact or interfere with each other and reduce their effects.
