Magnesium Glycinate vs Magnesium Citrate and Other Forms for Sleep
There are many types of magnesium supplements on the market.
Magnesium citrate is good for constipation and it is available in liquid or powder forms so is kid friendly.
What about magnesium glycinate for anxiety to help with sleep? Magnesium glycinate is one of my favorite forms of magnesium. It is well absorbed and may be helpful for mood, anxiety and sleep.
NOTE: There is a small group of people with the GAD1 gene variation who do not convert glycine to GABA well. They convert it to glutamate instead which may cause more anxiety. For some who do not tolerate glycine, GABA, glutamate or bone broth, there may actually be a vitamin B6 deficiency. Ask your practitioner about a B6 supplement.
Magnesium malate is well absorbed and promotes energy. It has been recommended for muscle pain, fibromyalgia and chronic fatigue syndrome although more studies are needed. For some people , it may be stimulating so it is best to take it in the morning.
The magnesium RDA for women is about 360 mg/day and for men about 420 mg/day. More magnesium may be recommended depending on your condition. Always check with your healthcare provider prior to supplementation.
