A recent study suggests that supplements of omega-3 may increase nitric oxide in the blood and increase blood flow, leading to better exercise performance in cyclists.

Participants in the study included 13 elite cyclists who were given either 1.3 g of omega-3s or a placebo daily for three weeks. At the conclusion of the study, the researchers noted an average increase in nitric oxide levels of 9.6 micromoles per liter in the omega-3 group, while the placebo group showed increases of only 1.4 micromoles per liter.

The researchers also noted a 5.25% increase in flow-mediated dilation in the omega-3 group. This was associated with notable increases in maximal oxygen intake when compared with the placebo.

Researchers from the Academy of Physical Education in Katowice and the Medical University of Silesia conducted the study. It was published in the June 2015 issue of the European Journal of Sports Sciences.

Omega-3s have been linked to a number of health benefits, including alleviating arthritis painbetter moods, improved joint mobility, helping with age related macular degeneration, and aiding your immune system.

Because omega-3 fatty-acids are not found naturally in the human body, it is especially important to make sure that they are a part of your daily diet. Oily, dark fish such as tuna and salmon are high in DHA and EPA omega-3s.

A recent study suggests that infant formula supplemented with omega-3 fatty acids may lead to longer and heavier children when compared with an infant formula that did not include omega-3 fatty acids.

Participants in the study included 69 infants who were raised from birth on formula. Fifty-nine of the babies were given a formula that included a long chain polyunsaturated fatty acid supplement, while the other 15 were given a control formula. They were fed these formulas for the first 12 months of their lives.

The researchers followed up with the children when they were six years old and found that the omega-3 group had higher length, stature, and weight-for-age percentiles from birth to 6 years of age when compared with the control group. However, the supplemented group did not have a higher BMI percentile compared to the control group.

They also found that the children of mothers who smoked had smaller length and stature, regardless of whether they took the omega-formula or the control. Those children also had higher BMIs.

Finally, the researchers noted that males had greater increases in stature associated with the supplemented formula when compared with females.

Researchers from the University of Kansas Medical Center and the University of Tennessee Health Sciences Center conducted the study. It was published online ahead of print on April 18, 2015, in the journal PLEFA.

Omega-3s have been linked to a number of health benefits, including alleviating arthritis pain, better moods, improved joint mobility, helping with age related macular degeneration, and aiding your immune system.

Mild cognitive impairment is the intermediate stage between the normal cognitive decline seen with aging and the more serious decline of dementia. A recent pilot study suggests that a drink containing a mix of omega-3s and mixed botanicals may have significant immune and biochemical effects on people with mild cognitive impairment.

Participants in the study included 12 people with mild cognitive impairment, two people with pre-mild cognitive impairment, and seven people with Alzheimer’s disease. They were given the 2000 mg drink containing high levels of DHA and EPA, resveratrol, vitamin D3 and other vitamins and antioxidants for between four and 17 months.

The researchers found that the people with mild cognitive impairment and pre-mild cognitive impairment had an increase in beta amyloid clearance from 530 to 1306 mean florescence intensity units. This was measured by looking at the destruction of beta amyloid by white blood cells called monocytes. Beta amyloid plaque buildup in the brain is associated with the progression of Alzheimer’s disease.

The researchers also found the anti-inflammatory resolvin RvD1 increased in the macrophages in 80% of the patients with mild cognitive impairment and pre- mild cognitive impairment. Macrophages are white blood cells that engulf and digest cellular debris, foreign substances, microbes, and cancer cells. Resolvin RvD1 has been shown to help clear out beta amyloid in labs.

The researchers also believe that supplementation may have helped stabilize the cognitive status of the participants with mild cognitive impairment and pre- mild cognitive impairment. They did not show any significant changes in their minimental state examinations, as would be expected over a long period of time from people suffering from mild cognitive impairment.

Researchers from UCLA conducted the study. It was published online ahead of print on March 24, 2015, in The FASEB Journal.

Omega-3s have been linked to a number of health benefits, including alleviating arthritis pain, better moods, improved joint mobility, helping with age related macular degeneration, and aiding your immune system.

The DHA form of omega-3s accounts for more than 10% of brain fatty acids and is important for brain development in babies. A recent study suggests that taking omega-3 supplements may help lactating women increase omega-3 levels in their breast milk and help babies achieve a better ratio of omega-3 to omega-6.

Participants in the study included 89 lactating women and their babies. All of the women were 4-6 weeks postpartum. They were given either a placebo, 200 mg DHA or 400 mg DHA for six weeks and told to follow their usual diets.

The researchers measured both breast milk and maternal plasma fatty acid levels in the mothers at the beginning and end of the study. Fatty acid levels in the infants were measured at the end of the study.

The researchers found that the 200 mg supplement was associated with a 50% increase in omega 3s in the breast milk and 71% increase in maternal plasma DHA, compared to placebo. The 400 mg dose showed even greater improvements, with 123% and 101% increases, respectively. 

The babies in the supplement groups had lower omega 6:3 ratios than those in the placebo group. Lower ratios have been associated with higher percentage of DHA in the three critical regions of the brain. Some studies suggest that an imbalance in the 6:3 ratio in the early stages of life may result in irreversible changes in the hypothalamus.

Researchers from Abbott Nutrition conducted the study. It was published online ahead of print on February 10, 2015, in the journal PLEFA.

Omega-3s have been linked to a number of health benefits, including alleviating arthritis pain, better moods, improved joint mobility, helping with age related macular degeneration, and aiding your immune system.

Systemic inflammation has been linked to an increase in the risk of a number of diseases, including depression, cancer, heart attack, diabetes, and Alzheimer’s disease.  A recent study suggests that a patented, purified form of omega-7 fatty acids may lower levels of C-reactive protein (CRP), a marker of inflammation, by as much as 44%.

The proprietary supplement used was sourced from anchovy or menhaden oil. It contained 50% palmitoleic acid and only a small amount of palmitic acid, which has been found to be associated with atherosclerosis, diabetes, and weight gain.

Participants in the study included 60 people with abnormal lipid levels and mild systemic inflammation, which was demonstrated by slightly elevated CRP levels. Over the course of 30 days, they were given either 220.5 mg of omega-7s in the form of cis-palmitoleic acid or 1000 mg of medium chain triglycerides as a placebo.

At the conclusion of the study, the omega-7 group had a 44% reduction in CRP, a 15% reduction in triglycerides, and an 8% reduction in LDL cholesterol levels. They also had an average 5% increase in HDL cholesterol, when compared with the placebo.

Researchers from the Cleveland Clinic conducted the study. It was published in the November-December issue of the Journal of Clinical Lipidology.

Previous studies suggest that omega-7 palmitoleic acid may help with insulin sensitivity, and slow the destruction of insulin-secreting pancreatic beta cells. Some of the many foods that contain palmitoleic acid include sea buckthorn berries, macadamia nuts, whale blubber, anglerfish liver, lard, baker’s yeast, butter, herring, avocado, cheddar cheese, and egg yolk.

Female pattern hair loss (FHPL) affects as many as 50% of women over the age of 50 and is usually seen as lower hair density, mainly in the crown and frontal scalp. A recent study suggests that taking a combination of omega-3s, omega-6s, and antioxidants may improve scalp coverage and the condition of hair in women suffering from FHPL.

Participants in the study included 120 healthy women who took either a specific blend of omega-3s and omega-6s from fish and blackcurrant seed oils combined with antioxidants or a placebo over the course of six months. At the conclusion of the study, the supplement group had improved hair density as measured by photograph assessment.

89.9% of the participants in the supplement group also reported a reduction in hair loss, 78.5% reported improvement in hair diameter, and 87.3% reported better hair density.  In the control group, 69.2% of the participants reported a reduction in hair loss, 33.3% reported improvement in hair diameter, and 64.1% reported better hair density.

Researchers from Laboratoires innéov in France conducted the study. It was published in the March 2015 issue of the Journal of Cosmetic Dermatology.

Omega-3s have been linked to a number of health benefits, including improved joint mobility, helping with age related macular degeneration, better moods, and aiding your immune system.

Because omega-3 fatty-acids are not found naturally in the human body, it is especially important to make sure that they are a part of your daily diet. Oily, dark fish such as tuna and salmon are high in omega-3s. If you don’t like fish, consider taking a daily high quality non-fish supplement that has been tested for purity and potency.

Omega-6 are also essential fatty acids that are not produced by the human body. Previous studies link them with improved brain functioning. However, the American diet often contains too many omega-6s and maintaining a balance between omega-6 and omega-3 is essential for good health.

Antioxidants are vital for good health because they combat free radicals. Free radicals break down cells in the body and can lead to heart disease, Alzheimer’s disease, rheumatoid arthritis and diabetes. The production of free-radicals can be increased as a result of smoking, pollution, alcohol, infection and stress.

A recent study suggests that taking vitamin D and omega-3s supplements together may help cognitive function and social behavior, especially in people who have ADHD, schizophrenia, and bipolar disorder.

Working with the knowledge that low serotonin levels exacerbate the conditions listed above, the researchers examined how vitamin D and omega-3s may affect them. They found that serotonin synthesis, release, and function in the brain are all modulated by vitamin D and EPA and DPA omega-3s, the two fatty acids that come from marine life.

They also noted that 70% of adults and 67% of children between the ages of one and eleven are vitamin D deficient, even when you take fortification and supplementation into account.

The researchers suggest that more studies should be done to determine optimal levels of vitamin D and omega-3s to help with these cognitive and behavioral disorders.  They also believe that they may be a potential a side effect-free alternative to serotonin-boosting prescription medications.

Researchers from the Children’s Hospital Oakland Research Institute conducted the study. It was published online ahead of print on February 24, 2015, in The FASEB Journal.

DHA and EPA are the two omega-3 fatty acids found in fish oil. Omega-3s have been linked to a number of health benefits, including improved joint mobility, helping with age related macular degeneration, better moods, and aiding your immune system.

Because omega-3 fatty-acids are not found naturally in the human body, it is especially important to make sure that they are a part of your daily diet. Oily, dark fish such as tuna and salmon are high in omega-3s. If you don’t like fish, consider taking a daily high quality non-fish supplement that has been tested for purity and potency.

Previous studies have associated vitamin D with reducing the risk of skin damage, reducing the risk of osteoporosis, combating diabetes, and improving age related macular degeneration.

Vitamin D can be found in milk, fortified cereals, fish, and eggs. Your body also processes vitamin D from the sun but it becomes harder for our bodies to process it as we age. A high quality vitamin D supplement is always a good option if you feel that you’re not getting enough through diet and sun.

While adopting a reduced calorie diet is a good approach to weight loss, there are also supplements that studies have found further enhance the weight loss process.  A recent study suggests that alpha-lipoic acid (ALA) supplements, taken with and without EPA fatty acid, may help obese and overweight women who are following a reduced calorie diet to lose weight.

Participants in the study included 97 overweight or obese women who followed a reduced calorie diet. Additionally, they were split into four treatments:

  • control group taking no supplements;
  • 1.3 grams of EPA daily;
  • 0.3 grams of ALA daily;
  • EPA and ALA.

The study period lasted for ten weeks and 77 women completed the study.

At the conclusion of the study, the control group lost an average of 11.7 lbs following just the reduced calorie diet. The EPA-only group lost an average 11.9 lbs. The ALA-only group lost an average 15.4 lbs, while the EPA plus ALA group lost an average 14.3 lbs.

The control and ALA-only group also showed lower levels of leptin. However, when EPA was combined with ALA, the leptin levels returned to normal. Leptin is the satiety hormone that tells the body when it is full.  It tends to decrease during weight loss.

Researchers from the University of Navarra conducted the study. It was published online ahead of print on December 31, 2014, in the journal Obesity.

Alpha-lipoic acid is an antioxidant that previous studies have linked with improvements in symptoms of diabetes. It can be found in yeast, liver, kidney, spinach, broccoli, and potatoes

There are two types of omega-3 fatty acids that come from fish: EPA and DHA. This study looked specifically at EPA. Because omega-3 fatty-acids are not found naturally in the human body, it is especially important to make sure that they are a part of your daily diet. Oily, dark fish such as tuna and salmon are high in DHA and EPA omega-3s.

If you don’t like fish or you’re worried about the high mercury levels found in some fish, consider taking a daily high quality supplement that has been tested for purity and potency.

A recent study suggests that a combination of borage and echium oils or fish oil may improve cholesterol levels and improve blood biomarkers in people with type-2 diabetes or metabolic syndrome.

Participants in the study included 59 people with early-stage type-2 diabetes or metabolic syndrome. Over the course of eight weeks they underwent one of three interventions:

1. a control in the form of corn oil;

2. a combination of borage and echium oils;

3. fish oil supplements.

At the conclusion of the study, the borage/echium oils group had a decrease in total cholesterol and LDL (“bad”) cholesterol. Total cholesterol dropped from 182.0 to 171.9 mg/dL and LDL cholesterol dropped from 106.3 to 96.8 mg/dL.

The fish oil group had increases in HDL (or “good”) cholesterol from 40.7 mg/dL to 53.6 mg/dL. They also showed a decrease in triglycerides from 187.2 to 156.8 mg/dL. The fish oil group also had decreases in the hemoglobin A1c test, which measures how well diabetes is being controlled.

Researchers from Wake Forest School of Medicine in North Carolina conducted the study. It was published on December 16, 2014, in Lipids in Health and Disease.

Fish oil and the omega-3s have been linked to numerous other health benefits, including combating diabetes, lowering cholesterol, improving vision, reducing the risk of dementia and relieving depression.

If you’re looking to increase your fish oil intake, try adding darker fish, such as salmon or tuna, to your diet. If you don’t like the taste of fish or are just finding it hard to work it into your meal plans, consider taking a high quality supplement. Make sure your supplement is tested for purity and potency.

Borage oil contains omega-6 fatty acids gamma-linolenic acid (GLA), linoleic acid (LA), as well as relatively high levels of oleic acid. Previous studies have linked it with easing skin disorders, rheumatoid arthritis, PMS, ADHD, and inflammation. It can be purchased as oil or eaten in salad or soups.

Previous studies have linked echium oil with improved immunity and lower inflammation, as well as lower risk of a cardiac event. It is especially important for vegetarians and vegans, who don’t eat fish or eggs and therefore do not get enough essential EPA and DHA omega-3s through their diet.

As we age, it becomes harder for our bodies to create and maintain strong muscles. A recent study suggests that increasing levels of polyunsaturated fatty acids (PUFAs) such as omega 3s may be associated with larger muscles and further knee extension in mature adults.

Participants in the study included 836 adults between the ages of 66 and 96. The researchers followed them for an average of 5.2 years. The researchers measured PUFA levels at the onset of the study.

After testing various measures of muscle size and strength, the researchers found that higher PUFA levels at the beginning of the study period were associated with both bigger muscles and further knee extension strength. When they looked at individual PUFAs, they discovered an association between higher levels of arachnidonic acid and smaller muscles, while higher levels of alpha-linolenic acids (ALA) were associated with greater knee extension strength.

Additionally, higher levels of alpha-linolenic acid were associated with lower levels of intermuscular fat tissue. Higher levels of EPA, however, were associated with higher levels of intermuscular fat tissue. Previous studies have shown an association between high levels of intermuscular fat tissue and lower muscle strength.

Researchers from the US National Institute on Aging, the VU University Medical Center in the Netherlands, Fred Hutchinson Cancer Research Center, the Icelandic Heart Association Research Institute, and the University of Iceland conducted the study. It was published online ahead of print on October 29, 2014, in The Journal of Nutrition.

Omega-3s are a great source of PUFAs. They have been linked to a number of health benefits, including alleviating arthritis pain, improved mood, improved joint mobility, helping with age related macular degeneration, and aiding your immune system.

Because omega-3 fatty-acids are not found naturally in the human body, it is especially important to make sure that they are a part of your daily diet. Oily, dark fish such as tuna and salmon are high in omega-3s.
