Restless Legs Syndrome
Folic Acid
People with familial restless leg syndrome appear to have an unusually high requirement for folic acid. Supplementing with folic acid may help relieve uncomfortable sensations.Dose:
Refer to label instructionsFolic AcidIn some people with RLS, the condition may be genetic. People with familial RLS appear to have inherited an unusually high requirement for folic acid. Although not all people with RLS suffer from uncomfortable sensations, folate-deficient people with this condition always do.2 In one report, 45 people were identified to be from families with folic acid-responsive RLS. The amount of folic acid required to relieve their symptoms was extremely large, ranging from 5,000 to 30,000 mcg per day.3 Such amounts should only be taken under the supervision of a healthcare professional.
L-Tryptophan
Preliminary research has shown some benefit reducing symptoms of restless legs syndrome and the insomnia that often accompanies it.Dose:
1 to 2 grams at bedtimeL-TryptophanSince restless legs syndrome is often accompanied by insomnia, and L-tryptophan has been helpful for promoting sleep,4 one investigator treated two patients having both restless legs syndrome and insomnia with 1 to 2 grams of L-tryptophan at bedtime.5 In both cases restless legs symptoms improved as well as insomnia. Controlled research is needed to confirm these findings.Magnesium
Supplementing with magnesium may help relieve insomnia in people with restless leg syndrome.Dose:
Refer to label instructionsMagnesiumIn a preliminary trial, people with period limb movements during sleep (PLMS) or RLS who suffered from insomnia had a significant improvement in sleep efficiency after supplementing with magnesium (about 300 mg each evening for four to six weeks).6
Vitamin D
In one small study, in people with a vitamin D blood level below 20 ng/ml, vitamin D supplementation decreased the severity of restless legs syndrome.Dose:
Refer to label instructionsVitamin DIn a study of 12 Saudi Arabian adults, the average blood level of vitamin D (measured as 25-hydroxyvitamin D) was very low (8.7 ng/ml). In people with a level below 20 ng/ml, vitamin D supplementation decreased the severity of restless legs syndrome by 62%.7 Double-blind trials are needed to confirm this studyVitamin E
In one study, supplementing with vitamin E produced complete relief in seven out of nine people with restless leg syndrome.Dose:
Refer to label instructionsVitamin EIn a group of nine people with RLS, 300 IU of vitamin E per day produced complete relief in seven.8 Doctors who give vitamin E to people with RLS generally recommend at least 400 IU of vitamin E per day, and the full benefits may not become apparent for three months.9
