In a 12-week trial of 139 healthy women averaging 71.5 years in a mild fitness program, 300 mg of magnesium oxide daily improved short physical performance battery scores, chair-stand times and 4-metre walking speed, most in women whose magnesium intake fell below the RDA.

Which iron supplement is better for iron deficiency anemia?
Over three months, 34 patients with iron deficiency anaemia on ferrous glycine sulphate gained 2.25 g/dL of haemoglobin, against 0.95 g/dL in 30 patients given ferric protein succinylate at the same elemental iron dose. The ferrous preparation was well tolerated and cheap.

Iodine may alleviate swelling in retinitis pigmentosa patients' retinas
In 212 patients with retinitis pigmentosa, retinal swelling from cystoid macular edema ran inversely to dietary iodine intake estimated from urine samples, Mass. Eye and Ear researchers report in JAMA Ophthalmology. They say this raises the possibility that iodine supplements could help.

Iodine may alleviate swelling in retinitis pigmentosa patients' retinas
Researchers at Mass. Eye and Ear, Harvard and Boston University measured 212 nonsmoking retinitis pigmentosa patients and found retinal swelling from cystoid macular edema was inversely related to estimated dietary iodine intake, raising the possibility that supplements could help.

Potassium supplements may increase survival in patients taking diuretics for heart failure
Penn researchers reviewed Medicaid records from 1999 to 2007 covering about 360,000 people starting loop diuretics and found better survival among those also prescribed potassium supplements, with the benefit growing at higher diuretic doses. The findings appear in PLOS ONE.

Zinc supplements maintain cognitive function in Alzheimer's disease
In a small six-month trial, Alzheimer's patients aged 70 and older who took zinc supplements maintained cognition and saw serum copper fall. The article argues inorganic copper from water and supplements raises risk, and urges readers to discard supplements containing copper.

Zinc supplementation may help fight depression
Drawing on two Australian cohorts of people aged 50 to 85, a study found those with the highest zinc intake had a 30 to 50% lower risk of depression than those with the lowest. The writer cautions against zinc oxide supplements, which often use nanoparticles.
Minerals
Seaweed supplements help iodine deficiency
Combet and colleagues at the University of Glasgow report in the British Journal of Nutrition that low-level seaweed supplementation improved iodine status in iodine-insufficient women. They tie the shortfall to low intakes of dairy products and seafood in the UK and other European countries.

Calcium Makes for an Environmentally Friendly Pickle
ARS researchers in Raleigh, North Carolina found calcium chloride can replace most of the sodium chloride in pickle brine, keeping cucumbers firm and speeding fermentation, and leaving a spent solution usable as a soil amendment. Mt. Olive Pickle Company has adopted it.

Zinc supplements fight asthma
In an 8-week randomized, double-blind trial in Sari, Iran, 284 children on inhaled steroids took 50 mg of zinc daily or a placebo. Researchers report the zinc group's serum zinc rose to 129 ug/dL and showed significant improvement in cough, wheezing, dyspnoea and all spirometry measures.

Calcium supplements reduce risk of pre-eclampsia
A Cochrane review led by G.J. Hofmeyr found that more than 1 gram of calcium a day during pregnancy reduced pre-eclampsia risk among women on low-calcium diets, and also lowered eclampsia and preterm birth. WHO advises 1.5 to 2 grams daily for such women.

Calcium supplements do not raise cardiovascular risk
Tracking 74,245 women in the Nurses' Health Study for 24 years, Brigham and Women's researchers found no independent link between calcium supplements and coronary heart disease or stroke. After adjustment, women taking 1 gram or more daily had 18 percent lower cardiovascular risk.

Zinc supplements help fight pneumonia in young children
In a double-blind trial of 120 children aged 3 to 60 months hospitalized with pneumonia, those given zinc alongside standard antibiotics had shorter symptoms and hospital stays than those given placebo. The authors say zinc can speed recovery as an adjuvant therapy.

Sodium, magnesium linked to hypertension
An analysis of 24-hour urine samples from 168 participants in India found high sodium and low magnesium intake were associated with higher blood pressure. The author notes magnesium runs high in leafy greens, nuts and seeds, beans and whole grains.

Selenium supplements prevent and treat PTSD
A study of patients at risk of post-traumatic stress disorder found selenium supplementation cut symptom severity by 5.85 percent and prevalence by 46.03 percent from baseline. The researchers tie PTSD to oxidative stress, which selenium may reduce.

Zinc deficiency before conception disrupts fetal development
Penn State researchers deprived female mice of dietary zinc before conception and saw frequent pregnancy loss, embryos averaging 38 percent smaller than controls, and about half showing delayed or abnormal development, along with poorly developed placentas.

Women of reproductive age should take iodine supplements
The American Academy of Pediatrics urges women of reproductive age to get enough iodine, warning that deficiency can disrupt fetal brain development and raise vulnerability to nitrate, thiocyanate and perchlorate. Only about 15% of women take iodine-containing supplements.

High potassium improves endothelial function
Thirty-five healthy adults averaging 32 years old followed six-day high- and low-potassium diets in a crossover trial. The high-potassium diet significantly improved flow-mediated dilatation and lowered E-selectin within a week, but left blood pressure unchanged.
