In a 12-week trial of 45 women whose depression had remitted but who still had antidepressant-induced sexual dysfunction, 3 grams of maca root powder a day improved scores on two sexual function scales. The effect was stronger in postmenopausal than premenopausal women.

Supplements
Antioxidants help obesity, diabetes mellitus
A McMaster University review concludes that antioxidant supplements such as zinc, lipoic acid, carnitine, cinnamon, green tea and vitamins C and E may offer only marginal protection against obesity and diabetes, and less than omega-3s, CoQ10, resveratrol or lycopene.

Cinnamon and statins together cause hepatitis - case report
A 73-year-old woman on long-term statins developed acute hepatitis after about a week of cinnamon supplements. She recovered once she stopped both and had no symptoms when she resumed the statin alone, so her doctors blamed the combination. Cinnamon contains coumarin, which can be liver-toxic.
Supplements
Resveratrol helps type 2 diabetes mellitus
Reviewing data on 196 type 2 diabetes patients, James Smoliga's team found resveratrol beat placebo on systolic blood pressure, hemoglobin A1c and creatinine but left fasting glucose, insulin resistance, triglycerides, LDL and HDL unchanged.

Pregnant Women Get New Access To Top-Rated Prenatal Vitamins
LabDoor has published rankings of prenatal vitamins based on lab assays of purity and label accuracy. CEO Neil Thanedar says the FDA provides no such service, and notes that one in nine U.S. babies is born pre-term and over 40 percent of women of childbearing age already take a daily prenatal.
Supplements
Fish Oil, Your Best Supplement
The author recounts a CNN story of a brain-injured young man who woke from a coma after his family raised his fish oil to 20 grams a day, then explains the EPA and DHA in over-the-counter capsules, molecular distillation, and everyday dosing.
Supplements
Brewer’s yeast helps diabetes mellitus
A meta-analysis of 14 trials with more than 800 patients found chromium supplementation as brewer's yeast significantly lowered fasting plasma glucose in diabetes, while chromium chloride, chromium yeast and picolinate did not. None of the forms significantly changed A1C.

Did TEDx Miss the Point on Potential Therapeutic Benefits of Hemp-derived CBD Oil?
TEDx Boca Raton cancelled Mike Zapolin's scheduled talk on hemp-derived CBD oil, writing that the city was not ready for a cannabis talk. His press release argues the talk would have countered myths about a plant used for more than 10,000 years.
Supplements
Protein, amino acid supplements prevent muscle loss during a weight loss intervention
In 80 obese older adults, a supplement enriched with whey protein, leucine and vitamin D helped prevent muscle loss during a 13-week weight loss program, suggesting protein or branched-chain amino acid supplements may protect muscle while dieting.
Supplements
Psyllium fiber lowers cholesterol
In a randomized, double-blind trial, 51 children aged 6 to 19 with mild-to-moderate high cholesterol took 7 grams of psyllium husk or cellulose daily for eight weeks. Total cholesterol fell nearly 8% and LDL about 11% in the psyllium group, with no side effects observed.
Supplements
Carnitine supplements help metabolic symdrome
Czech researchers gave carnitine to rats bred with high blood fat for eight weeks. The supplemented rats gained less weight and had less liver steatosis, lower fasting triglycerides and reduced oxidative stress, suggesting carnitine may ease some metabolic syndrome markers.
Supplements
Fish oil benefits can be null when polluted with PCBs
Swedish researchers followed 33,446 women free of heart disease for 12 years to test whether PCB contamination offsets the heart benefits of long-chain omega-3s from fish and fish oils, and suggest polluted fish or oil may not protect against heart attack.
Supplements
Lutein, zeaxanthin, vitamin C linked to telomere length
In the Austrian Stroke Prevention Study, elderly people with higher serum vitamin C, lutein and zeaxanthin had longer leukocyte telomeres, regardless of body mass index, oxygen uptake or vascular conditions. The study did not test whether the nutrients affect lifespan.
Supplements
Iron supplementation helps recover after blood donation - study
The NIH-funded HEIRS study found low-dose iron supplements significantly shortened the time blood donors needed to recover lost iron and hemoglobin. About 25-35% of regular donors develop iron deficiency, which can otherwise take months to reverse.
Supplements
Alpa-lipoic acid helps weight loss
In a 10-week trial, 97 overweight or obese women cut calories by 30 percent while taking alpha-lipoic acid, EPA, both or neither. Weight loss was significantly greater in the women given alpha-lipoic acid, while EPA blunted the fall in leptin that accompanies weight loss.
Supplements
Fructans protect against colon cancer
Rats fed a fructan-rich supplement from Agave salmiana developed significantly fewer early colon cancer lesions than controls after azoxymethane exposure, a Natural Product Communications study reports. The authors suggest agave fructans may lower colon cancer risk as inulin-like fructans do.
Supplements
Propionate supplement reduces energy intake, prevents weight gain
In a 24-week crossover trial with 60 overweight adults, 10 grams of inulin-propionate ester stimulated PYY and GLP-1 and cut energy intake. Over the study the supplement reduced weight gain, intra-abdominal fat and liver fat and preserved insulin sensitivity.
Supplements
Citrus limetta peel extract helps diabetes mellitus
A Mexican study found Citrus limetta peel extract at 20 mg/ml inhibited alpha-amylase by nearly 50 percent and alpha-glucosidase by nearly 30 percent, enzymes that break down carbohydrates. The researchers credit the peel's antioxidative polyphenols.
