For muscle pain, highly absorbable oral forms like Magnesium Citrate (good for cramps/lactic acid), Magnesium Glycinate (calming/relaxation), and Magnesium Malate (muscle aches/fibromyalgia) are excellent, while Magnesium Chloride/Sulfate (Epsom Salts) are best for topical relief through baths or oils, supporting muscle relaxation and recovery.
Magnesium citrate: The citric acid salt of magnesium is good for muscle soreness and constipation. It is absorbed well, especially in the liquid form. Magnesium glycinate: The amino acid glycine salt is good for insomnia, anxiety, and tense muscles, but more research is needed on its benefits. It is easily absorbed.
There have been few studies of magnesium for the treatment of leg cramps in pregnancy. Dahle et al. demonstrated the therapeutic effect of magnesium lactate/magnesium citrate against leg cramps in pregnancy when compared with placebo (Dahle et al. 1995).
The recommended daily dosage depends on your gender and age: For men: 400 mg for ages 19 to 30, 420 mg for ages 31 and older. For women: 310 mg for ages 19 to 30, 320 mg for ages 31 and older. For children: 80 mg for ages 1 to 3 years, 130 mg for ages 4 to 8 years, 240 mg for ages 9 to 13 years.
[51] showed that magnesium citrate is the best type for muscle efficiency. Regarding the dosage of MgS, the studies selected for this systematic review administered from 300 to 500 mg. Generally, the daily magnesium supplementation should be between 360 to 420 mg in adulthood [52].
Ultimately, it depends on your individual needs and tolerance. Both magnesium citrate and magnesium glycinate may support muscle health and cramping when dietary intake of magnesium is inadequate. However, some people prefer magnesium glycinate due to its gentler effects on digestion and calming properties4.
Magnesium malate is best used for muscle soreness, chronic inflammation, fibromyalgia, and improving energy.
Individuals with diabetes, intestinal disease, heart disease, or kidney disease should avoid magnesium unless specifically instructed by their healthcare provider. Overdose: Signs of a magnesium overdose include nausea, diarrhea, low blood pressure, muscle weakness, and fatigue.
For constipation, choose magnesium citrate. For better sleep or reduced anxiety, look for magnesium glycinate. For active kids, magnesium malate may be the best choice.
Symptoms of magnesium deficiency include low appetite, nausea or vomiting, muscle spasms or tremors and abnormal heart rhythms.
Both low vitamin D and calcium lead to increased muscle cramps. Vitamin B1 is also called thiamine. Your body uses it to produce energy. Low vitamin B1 can lead to a condition called beriberi, which causes leg pain and cramps.
Magnesium bisglycinate is one of the purest forms of magnesium. It is very well absorbed and tolerated. This form of magnesium has very high absorption into the body to help eliminate what causes muscle cramps, works very fast and has virtually no gastrointestinal side effects.
No vitamin is likely to help with a leg cramp 100% of the time. But some experts do recommend that you take a vitamin B complex or magnesium for leg cramps.
High doses of magnesium glycinate may cause diarrhea, gas, or stomach pain. Very high or long-term use can lead to magnesium toxicity. People with kidney or heart disease, or certain neuromuscular conditions, should avoid it without consulting a doctor.
Magnesium Glycinate – This is one of the most recommended types for ADHD. It's gentle on the stomach, absorbs well, and has calming properties that may help with anxiety, irritability, and sleep.
Choose magnesium glycinate for sleep, stress relief, muscle recovery, and gentle absorption. Choose magnesium citrate for regularity, digestive support, or replenishing electrolytes. You can also use both strategically—glycinate at night to unwind, and citrate earlier in the day for digestive and hydration support.
For many people, it's important to take vitamin D and magnesium together. Without magnesium, your body can't use vitamin D. And if you take vitamin D supplements, this can make a magnesium deficiency worse. There are natural ways to increase both your vitamin D and magnesium levels.
Signs of low magnesium
So magnesium glycinate may help you sleep better and make it less likely to wake up during the night. Research is still early but some studies show small improvements in sleep among adults with low magnesium levels. Muscle and nerve support: Low magnesium can cause cramps, muscle twitches and fatigue.
Magnesium Bisglycinate : is a highly absorbable form of magnesium that has soothing effects on muscles and joints, ideal for improving flexibility and reducing joint pain. Magnesium Citrate – This type of magnesium is quickly absorbed into the body and is effective in relieving inflammation and promoting joint health.
When taken in doses greater than 350 mg daily, magnesium is possibly unsafe. Large doses might cause too much magnesium to build up in the body, causing serious side effects including an irregular heartbeat, low blood pressure, confusion, slowed breathing, coma, and death.
Research suggests that magnesium may take around 10 days to show noticeable benefits for muscle soreness in active individuals. In a study of magnesium supplementation and muscle recovery, participants experienced improvements in markers of muscle soreness over this timeframe.
While magnesium glycinate is an effective tool for managing cortisol levels, there are several other natural strategies that individuals can employ to promote balance in their bodies.
The key is to use the correct forms of magnesium. The best is magnesium taurate or magnesium malate for fibromyalgia. These typically offer the most efficient absorption. Magnesium citrate, which is the most commonly found is a good laxative but not for maximum absorption.
