Hesperidin and curcumin boosted performance and recovery Hesperidin increased antioxidant capacity The antioxidant hesperidin comes from oranges. In this study, 40 amateur cyclists, aged 18 to 55, with healthy weight, took a placebo or 500 mg of hesperidin per day over a period of eight weeks, during which they completed five cycling tests of sustainable and maximum power. Before each of the five tests, participants ate the same breakfast of measured carbohydrates, proteins,


Calm
L-theanine relaxed healthy adults Stress-hormone cortisol levels decreased Humans use the stress response to survive threats, and to help achieve challenging goals, but chronic stress can have negative health effects. In this study, 15 healthy adults reporting moderate levels of stress took a placebo or a single 200 mg dose of L-theanine, pausing for a week, then switching supplement and placebo groups. To induce stress, doctors gave a mental math test before, and 45 minutes

Nutrients reduced inflammatory factors and pain in type 2 diabetes
Vitamins D, E, and resveratrol Vitamins D, delta-tocotrienol E, and resveratrol have cholesterol-reducing, anti-inflammatory, and antioxidant effects, which doctors tested, separately and together, on metabolic markers in type 2 diabetes. In the first phase of the study, 120 participants took a placebo, or individually 10,000 IU of vitamin D, 500 mg of delta-tocotrienol, or 500 mg of resveratrol, half after breakfast, and half after dinner. In the second phase, 56 participant


Early-Stage Discoveries: Amino Acids, Probiotics, Krill Oil
Good results in the lab can lead to larger human trials. Here are some of the most promising recent findings. Amino acids linked to brain health Low-protein diets have a link to poor brain function. In the lab, mice on a low-protein diet had accelerated brain impairment, effects that reversed after supplementing with seven amino acids: leucine, phenylalanine, lysine, isoleucine, histidine, valine, and tryptophan. To find out how, doctors measured gene-level changes that revea


Green Tea for Flu
Researchers reviewed eight green tea extract studies, covering 5,048 participants, and found on average overall, those who regularly consumed green tea extracts were 33 percent less likely to contract the flu compared to placebo. Green tea contains catechins and its constituent, epigallocatechin-gallate (EGCG), the active ingredients. A 3.5-ounce brewed cup of green tea typically contains 100 to 150 mg of catechins, and about 80 mg of EGCG. Doctors say gargling with 100 to 28


Women
Nutrients improve pregnancy and perimenopause Pre- and probiotics reduced nausea in pregnancy Elevated levels of estrogen and progesterone in pregnancy alter the microbiome, and may cause nausea, vomiting, and other gut symptoms in 85 percent of expectant mothers. In this study, 32 pregnant women took 200 mg of inulin plus a combination of 10 probiotics in 10 billion colony-forming-units per day, for six days, then stopping for two days. The women answered questionnaires each


Good Digestion
Everyday nutrients promote gastrointestinal health Vitamin D protects against cancer People eating the refined diet typical of developed countries may have greater chances for colorectal cancer, with low levels of vitamin D raising chances further. As this study revealed, Black populations in the U.S. are more likely than any other domestic racial or ethnic group to have these issues, and are also more likely to be low in vitamin D. In this study, doctors gave food questionna
