Can More Vitamin D Early in Life Help Prevent Alzheimer’s?
An innovative new study provides a mechanism by which getting more vitamin D earlier in life might help prevent Alzheimer’s disease later in life.
A protein named tau is essential for the health of nerve cells. But if tau molecules begin to bunch up into neurofibrillary tangles, they begin to damage the very cells they were meant to keep healthy. Tau tangles are an important marker of cognitive impairment: the more neurofibrillary tangles inside the brain cells, the worse the cognitive impairment.
Several studies have shown that low levels of vitamin D are associated with an increased risk of cognitive impairment and dementia.
A just published study set out to explore the possibility that more vitamin D early in life might prevent tau tangles later in life. If that possibility proved true, that would give rise to the possibility that getting more vitamin D might help prevent Alzheimer’s disease.
The study included 729 people with an average age of 39 who did not have dementia at the beginning of the study. At the beginning of the study, they had their vitamin D levels measured. 16 years later, they had PET scans. Higher levels of vitamin D were associated with significantly lower tau depositions in the brain. This result was found both for the brain in general and in the regions of the brain that are the earliest affected in Alzheimer’s.
What’s especially exciting about this study is not just the discovery of a possible mechanism by which vitamin D might help prevent Alzheimer’s, but the demonstration that vitamin D could significantly improve markers of dementia in early midlife when there is a greater chance of reducing the risk of Alzheimer’s.

Can Aromatherapy With Thyme Essential Oil Help People With COVID?
Can something as simple as smelling thyme essential oil help people hospitalized with COVID?
This open-label study included 140 people who were hospitalized for COVID. They all received conventional treatment, but half of them added thyme essential oil aromatherapy. 2mL of essential oil was applied to a cotton wick inside an inhaler stick. People in the aromatherapy group closed one nostril and inhaled 8 times through the other, 3 times a day for 5 days.
The thyme aromatherapy group improved significantly more, especially in shortness of breath (dyspnea), cough, secretions and fatigue. They also improved significantly more in musculoskeletal pain, headache, dizziness, diarrhea and appetite loss.
In addition to improvements in symptoms, there was also significantly greater improvement in vital signs in the aromatherapy group, including temperature, blood pressure, pulse rate, oxygen saturation and respiratory rate.
This study suggests that simply adding thyme aromatherapy to treatment can benefit people with COVID.
Though the result is exciting, caution is needed, since the study was not double-blind.

New Research Introduces Spirulina for Multiple Sclerosis
This new study shows that spirulina can safely improve many aspects of multiple sclerosis (MS).
Multiple sclerosis (MS) is a debilitating autoimmune disorder in which inflammation and oxidative stress trigger a CNS immune response that leads to demyelination of the myelin sheath.
MS impairs quality of life because of mobility limitations, chronic fatigue, cognitive decline and sexual dysfunction.
This new triple-blind study gave 64 people with MS either a placebo or 1g of spirulina a day for 12 weeks.
Compared to placebo, spirulina significantly reduced body weight, which is important because that could help modulate metabolic risks, like cardiovascular disease and diabetes.
Spirulina significantly decreased markers of inflammation, while there was no improvement in the placebo group.
Spirulina was significantly better for improving health perception, physical function, limitations on physical roles, energy and sexual function.
The spirulina was very safe, with even fewer people having to stop treatment than in the placebo group.
This study suggests that spirulina can be a safe and affordable addition to MS therapy.

Natural Combo Relieves PMS
Premenstrual syndrome affects nearly half of all women in the world during their reproductive years. The discomfort can profoundly affect quality of life. This novel natural combination can help, according to a new study.
Premenstrual syndrome (PMS) usually occurs in the week before menstruation and can include bloating, breast tenderness, headaches, palpitations, depression, irritability, fatigue, poor concentration, mood swings and even suicidal thoughts.
Conventional medicine treats women with PMS with NSAIDs, hormones and SSRI antidepressants. But these extreme measures commonly cause new problems, like weight gain, mood swings, and sexual dysfunction. Several natural herbs and supplements have demonstrated the ability to safely relieve the symptoms of PMS. This new study put a number of them together in a natural PMS combo.
The double-blind study gave 218 women with PMS either a placebo or a natural combination supplement. The supplement contained 50mg of lavender extract, 13mg of saffron extract, 40mg of valerian extract, 40mg of spirulina, 10mg of curcumin, 25mg of chamomile extract, 100mg of rose extract, 56mg of B1, 50mg of calcium citrate and 90mg extract of a herb called lesser dodder. The combo supplement was taken twice a day, starting 7 days before expected menstruation and continuing for 3 days after onset for two cycles.
PMS symptoms were measured on the Daily Record of Severity of Problems (DRSP) questionnaire.
Improvement in DRSP scores was significantly better in the first month. The improvement was even more pronounced in the second month. In the placebo group, scores improved from 37.86 to 28.61 in the second month. But in the supplement group, scores improved much more from 43.28 to 21.02 in the second month.
Premenstrual dysphoric disorder, or PMDD, is a severe form of PMS that brings significant mood disturbances and functional impairment. When women with PMDD took a placebo, DRSP scores improved from 44.94 to 36.27. But in the supplement group, the improvement was a significantly better drop from 48.26 to 30.13.
This study suggests that a combination of natural supplements, each of which individually could help PMS, can offer safe, significant relief of the physical and psychological symptoms of PMS.

Beating Cancer with a Cup of Tea
Could something as simple and delicious as drinking green tea reduce your risk of cancer? According to new research, the answer is yes!
A new meta-analysis of 43 studies has shown that drinking green tea reduces the risk of cancer by 9% and taking EGCG in a green tea extract reduces it by 28%. EGCG is the most abundant antioxidant found in green tea.
As exciting as these results are, they were more spectacular for certain cancers. The risk of prostate cancer was reduced by a significant 57%, oral cancer by 56%, gallbladder cancer by 28% and blood cancers by 28%.

Ashwagandha Improves Cognition
Low energy and stress can have a detrimental impact on cognition. Ashwagandha is a powerful adaptogenic herb that has been shown to help energy, stress and cognition.
This new double-blind study gave 115 people with low energy who were also experiencing attention or memory issues either a placebo or 300mg of ashwagandha extract twice a day for 8 weeks.
Compared to placebo, ashwagandha safely led to significant improvement in memory, working memory, attention and learning. The people taking ashwagandha also had significant improvement in mood, energy and executive function.

Pomegranate for Arthritis
Rheumatoid arthritis and osteoarthritis lead to joint destruction, pain and disability. A new meta-analysis suggests that supplementing pomegranate may help.
This meta-analysis of controlled studies found that supplementing pomegranate extract or juice helps people with arthritis.
In rheumatoid arthritis, it significantly reduced disease activity scores and markers of inflammation while increasing antioxidant activity. Given that arthritis is characterized by chronic inflammation and oxidative stress, this is good news.
In osteoarthritis, pomegranate significantly improved WOMAC scores, which evaluate pain, stiffness, and physical function; KOOS scores, which measure pain, knee-related quality of life, function in daily living and in sports and recreation; and subjective improvement.
Pomegranate supplementation was well tolerated with no serious adverse events.
This meta-analysis demonstrates the promising anti-inflammatory and antioxidant effects of pomegranate for people with arthritis.

Gotu Kola Protects Your Eyes from Macular Degeneration
Macular degeneration is a product of free radical damage and declining antioxidant protection. It can cause difficulty seeing things directly in front of you. In the U.S., it is the leading cause of visual impairment in people over 60. A well known traditional herb from South and Southeast Asia can help, according to a new study.
Your retina is especially sensitive to oxidative damage. Macular pigment filters damaging light and protects your retina from oxidative damage. It is mostly composed of the carotene antioxidants lutein and zeaxanthin. Degeneration of the macula caused by this free radical damage is a common cause of visual impairment.
This double-blind study gave 75 men and women who were between 45 and 65 either a placebo or 300mg of gotu kola extract a day for 6 months. The study wanted to see the effect of gotu kola on macular pigment optical density (MPOD), a marker of the antioxidant status of the macula.
At the end of the study, supplementing gotu kola led to a significant increase in MPOD compared to placebo in the left eye, in the right eye and in the average of both eyes. Significantly more people in the gotu kola group responded than in the placebo group with 32.43% of the placebo group responding versus a significantly better 94.74% of the gotu kola group.
There were fewer adverse events in the herb group than in the placebo group. There were no serious adverse events, and none were related to the treatment.
This study suggests for the first time that gotu kola can help maintain macular health.

Getting More Folic Acid Reduces the Risk of Obesity for Adolescents
Rates of obesity among young people are very concerning and on the rise. Between 1990 and 2021, rates of overweight and obesity combined doubled, while rates of obesity tripled. Any safe, natural help would be welcome. Here’s a surprising and simple one.
Rising rates of obesity among young people is concerning because being overweight when you’re young has impacts on health when you’re an adult, including increased risk of cardiovascular disease, diabetes, cancer and premature death.
Studies have shown that a B vitamin, folic acid, is associated with lower rates of overweight and obesity in adults. But what about in kids?
This massive study of 9,404 children and adolescents between 6 and 19 found that folic acid is also associated with a lower risk of being overweight or obese in young people, especially adolescents.
Compared to people with the lowest dietary intake of folic acid, those with the highest had a 35% lower risk of being overweight or obese. For central obesity, the benefit was a similar 36%. This benefit for folic acid reached significance for adolescents between 12 and 19.
This new study introduces folic acid as a possible strategy for combatting overweight and obesity in children and, especially, in adolescents.

Research Shows That This Vitamin Fights Migraines
It’s hard to believe, but a billion people suffer from migraine headaches. It’s also hard to believe that a safe, simple, inexpensive vitamin can help. Both are true.
Could something as simple as vitamin D change life for millions of people with migraines? That’s what this meta-analysis of 5 studies that compared vitamin D to a placebo set out to see.
The answer is yes! Vitamin D significantly reduced the number of days with headaches, the frequency of headaches and the severity of headaches. It also significantly improved scores on the Migraine Disability Assessment.
The researchers concluded that “Vitamin D treatment is effective to alleviate migraine.”

Artichoke Extract Helps Non-Alcoholic Fatty Liver Disease
Rates of obesity and of non-alcoholic fatty liver disease (NAFLD) are on the rise. Artichoke is a powerful natural remedy for the liver. This study put artichoke to the test against overweight people with NAFLD.
As many as 90% of people who undergo bariatric surgery for obesity have metabolic dysfunction-associated steatotic liver disease (MASLD), the new name for NAFLD.
Previous research has shown that artichoke extract can reduce hepatic stenosis, the excess fat in your liver, and decrease liver size in nonobese people with MASLD (J Diagn Med Sonogr. 2022; 38:540-547). This single-blind, placebo-controlled study included 40 people with MASLD who were overweight and scheduled for bariatric surgery. Each was given either a placebo or 2,600mg of artichoke extract standardized for 2.5% cynarine. The study lasted for 6 weeks.
While liver stenosis in the placebo group did not improve, it improved significantly in the artichoke group. Stenosis severity improved significantly more in the artichoke group.
While liver size was not reduced in the placebo, it was significantly reduced in the artichoke group. The size of the liver was significantly smaller in the artichoke group.
This study continues to establish artichoke as an important herb for liver health. Specifically, this study suggests that artichoke extract can reduce liver stenosis and liver size in overweight people with MASLD.
