Dietary Polyphenol Supplementation Prevents Alterations of Spatial Navigation in Middle-Aged Mice - Front Behav Neurosci. 2016 Feb 9 - "In this study, spatial learning deficits of middle-aged mice were first highlighted and characterized according to their navigation patterns in the Morris water maze task. An eight-week polyphenol-enriched diet, containing a polyphenol-rich extract from grape and blueberry (PEGB; from the Neurophenols Consortium) with high contents of flavonoids, stilbenes and phenolic acids, was then successful in reversing these age-induced effects. The use of spatial strategies was indeed delayed with aging whereas a polyphenol supplementation could promote the occurrence of spatial strategies. These behavioral results were associated with neurobiological changes: while the expression of hippocampal calmodulin kinase II (CaMKII) mRNA levels was reduced in middle-aged animals, the polyphenol-enriched diet could rescue them. Besides, an increased expression of nerve growth neurotrophic factor (NGF) mRNA levels was also observed in supplemented adult and middle-aged mice. Thus these data suggest that supplementation with polyphenols could be an efficient nutritional way to prevent age-induced cognitive decline" - [

Grape seed promise in fight against bowel cancer - Science Daily, 2/14/14 - "Our research also showed that in laboratory studies grape seed taken orally significantly reduced inflammation and tissue damage caused by chemotherapy in the small intestine, and had no harmful effects on non-cancerous cells. Unlike chemotherapy, grape seed appears to selectively act on cancer cells and leave healthy cells almost unaffected ... The research showed grape seed extract: ... showed no side effects on the healthy intestine at concentrations of up to 1000mg/kg; ... significantly decreased intestinal damage compared to the chemotherapy control; ... decreased chemotherapy-induced inflammation by up to 55% ... increased growth-inhibitory effects of chemotherapy on colon cancer cells in culture by 26%" - See grape seed extract at Amazon.com.
Grape seed and skin extract: A weapon in the fight against kidney disease caused by high-fat diets - Science Daily, 2/28/13 - "Grape seed and skin extract (GSSE) is known to contain powerful antioxidants ... Rats were fed a high-fat diet that induced a low-grade reno-lipotoxicity, that is, kidney damage associated with lipids. This was characterized by elevations in plasma urea and protein in the urine. The researchers found increased deposits of triglycerides (TG) (especially saturated fatty acids), increased signs of oxidative stress and depleted copper levels in the kidneys. There was also histological evidence of disturbance in the kidney structure. When the animals received GSSE at 500 mg/kg bw (which corresponds to 35g/day for a 70 kg human adult) along with the high-fat diet there was a partial reversal of the TG deposition as well as the histological damage. The authors suggest polyphenols including resveratrol are likely the components in GSSE responsible for the positive effects. Furthermore the GSSE prevented the oxidative stress and copper depletion" - See grape seed extract at Amazon.com.
Grape intake may protect against metabolic syndrome-related organ damage
- Science Daily, 4/22/13 -
"Natural components found in grapes, known as polyphenols, are thought to be responsible for these beneficial effects ... The grapes -- a blend of red, green and black varieties -- were provided as a freeze-dried grape powder and integrated into the animals' diets for 90 days ... three months of a grape-enriched diet significantly reduced inflammatory markers throughout the body, but most significantly in the liver and in abdominal fat tissue. Consuming grapes also reduced liver, kidney and abdominal fat weight, compared with those consuming the control diet ... Metabolic syndrome is a cluster of conditions that occur together -- increased blood pressure, a high blood sugar level, excess body fat around the waist or low HDL (the good cholesterol) and increased blood triglycerides" - See grape seed extract at Amazon.com.
As colorectal cancer gets more aggressive, treatment with grape seed extract is even more effective, study shows - Science Daily, 1/16/13 - "the more GSE inhibits their growth and survival. On the other end of the disease spectrum, GSE leaves healthy cells alone entirely ... We've known for quite a while that the bioactive compounds in grape seed extract selectively target many types of cancer cells. This study shows that many of the same mutations that allow colorectal cancer cells to metastasize and survive traditional therapies make them especially sensitive to treatment with GSE ... 60 percent of patients diagnosed have already reached the advanced stage of the disease"

Grape seed extract kills head and neck cancer cells, leaves healthy cells unharmed - Science Daily, 1/27/12 - "Nearly 12,000 people will die of head and neck cancer in the United States this year and worldwide cases will exceed half a million ... grape seed extract both damages cancer cells' DNA (via increased reactive oxygen species) and stops the pathways that allow repair (as seen by decreased levels of the DNA repair molecules Brca1 and Rad51 and DNA repair foci) ... we saw absolutely no toxicity to the mice ... the grape seed extract killed the cancer cells but not the healthy cells" - See grape seed extract at Amazon.com.
Natural chemical found in grapes may protect against Alzheimer's disease - Science Daily, 7/16/11 - "grape seed polyphenols -- a natural antioxidant -- may help prevent the development or delay the progression of Alzheimer's disease ... This is the first study to evaluate the ability of grape-derived polyphenols to prevent the generation of a specific form of ß-amyloid (Aß) peptide, a substance in the brain long known to cause the neurotoxicity associated with Alzheimer disease ... administered grape seed polyphenolic extracts to mice genetically determined to develop memory deficits and Aß neurotoxins similar to those found in Alzheimer's disease. They found that the brain content of the Aß*56, a specific form of Aß previously implicated in the promotion of Alzheimer's disease memory loss, was substantially reduced after treatment" - See grape seed extract at Amazon.com.
Grape seed procyanidins in pre- and mild hypertension: a registry study - Evid Based Complement Alternat Med. 2013;2013:313142 - "The efficacy of a standardized grape seed procyanidins extract (GSPE, Enovita) to decrease blood pressure when associated with nondrug intervention (diet and lifestyle modifications) was investigated in a controlled registry study involving 119 healthy, pre- and mildly hypertensive subjects. Two dosages of Enovita were evaluated (150 and 300 mg/die) ... After four months of treatment, a statistically significant higher, and dose-dependent, improvement in all endpoints was observed in the treatment groups compared to that of the control, with blood pressure normalizing in 93% of the higher dosage (300 mg) treatment group. Taken together, these observations suggest that GSPEs have beneficial cardiovascular effects that complement current intervention strategies in the hypertension area. The effect on blood pressure adds to the beneficial effects of GSPEs on the cardiovascular disease (CVD) phenotype associated with the oxidation of membrane lipids (endothelial dysfunction, formation of oxidized LDL, and activation of phagocytic cells)" - See grape seed extract at Amazon.com.
LDL cholesterol-lowering effects of grape extract used as a dietary supplement on healthy volunteers - Int J Food Sci Nutr. 2012 Dec 19 - "A randomized, double-blind, placebo-controlled clinical trial was performed over 56 days and included 60 volunteers. Thirty volunteers took 700 mg of the grape extract, Eminol® (E), and 30 took the placebo (P). On comparison of the results, a decrease in total cholesterol (E: 213.77 +/- 4.1 mg/dl and P: 245.57 +/- 4.1 mg/dl; p = 0.01) and LDL cholesterol (E: 142.17 +/- 3.1 mg/dl and P: 165.13 +/- 3.1 mg/dl; p = 0.02) levels as well as an increase in antioxidant capacity (E: 65.63 +/- 5.8 µmol TE/mg and P: 57.80 +/- 7.7 µmol TE/mg; p < 0.01) and vitamin E (E: 11.46 +/- 0.5 µg/ml and P: 9.06 +/- 0.5 µg/ml; p = 0.018) was observed. This result indicates that the grape extract Eminol® modulated the lipid profile in terms of cardiovascular risk indicators, lowering total blood cholesterol and LDL cholesterol levels" - See grape seed extract at Amazon.com.

Pycnogenol® improves cognitive function, attention, mental performance and specific professional skills in healthy professionals aged 35-55 - J Neurosurg Sci. 2014 Dec;58(4):239-48 - "Pycnogenol® (150 mg/day) ... Cognitive function, attention, mental performance, sustained attention, memory, executive functions, mood and oxidative stress values were comparable at inclusion. At 12 weeks the improvement in Pycnogenol® subjects was more significant than in controls. Plasma-free radicals (oxidative stress) were significantly decreased (median -30.4%) at 12 weeks in Pycnogenol® subjects in comparison with a non-significant variation observed in controls (+0.9%; difference between groups). Considering the cognitive test battery (PASAT, pattern recognition memory, spatial recognition memory, spatial working memory), Pycnogenol® subjects showed a small but significant improvement with spatial recognition memory unchanged. Mood parameters (alertness, anxiety, contentedness) also improved in professionals using the supplement. In the evaluation of 12 professional daily tasks all items were improved with Pycnogenol® supplementation. The score relative to semi-professional minitasks was improved more in Pycnogenol® subjects.

Evaluation of the effects of supplementation with Pycnogenol® on fitness in normal subjects with the Army Physical Fitness Test and in performances of athletes in the 100-minute triathlon - J Sports Med Phys Fitness. 2013 Dec;53(6):644-54 - "physical fitness (PF) ... Army Physical Fitness Test (APFT) ... divided into 2 parts. In PART 1 (Pycnogenol 100 mg/day), the APFT was used to assess an improvement in PF during an 8-week preparation and training program. In PART 2 (Pycnogenol 150 mg/day), the study evaluated the effects of Pycnogenol supplementation in athletes in training for a triathlon ... Results: PART 1. There was a significant improvement in both males and females in the 2-mile running time within both groups, but the group using Pycnogenol (74 subjects) performed statistically better than controls (73 subjects). The number of push-ups was improved, with Pycnogenol subjects performing better. Sit-ups also improved in the Pycnogenol group. Oxidative stress decreased with exercise in all subjects; in Pycnogenol subjects the results were significantly better. PART 2. In the Pycnogenol group 32 males (37.9; SD 4.4 years) were compliant with the training plan at 4 weeks. In controls there were 22 subjects (37.2;3.5) completing the training plans. The swimming, biking and running scores in both groups improved with training. The Pycnogenol group had more benefits in comparison with controls. The total triathlon time was 89 min 44 s in Pycnogenol subjects versus 96 min 5 s in controls. Controls improved their performing time on average 4.6 minutes in comparison with an improvement of 10.8 minutes in Pycnogenol subjects. A significant decrease in cramps and running and post-running pain was seen in the Pycnogenol group; there were no significant differences in controls. There was an important, significant post-triathlon decrease of PFR one hour after the end of the triathlon with an average of -26.7, whereas PFR in controls increased. In Pycnogenol subjects there was a lower increase on oxidative stress with a faster recovery to almost normal levels (<330 for these subjects). These variations in PFR values were interpreted as a faster metabolic recovery in subjects using Pycnogenol" - See Pycnogenol at Amazon.com.
