Cinnamon Improves Glycemic Control in Diabetics

Cinnamon is not only one of the most promising toppings for your breakfast bun, it is also one of the most promising treatments for diabetes. This new study keeps the evidence piling up and reveals important benefits.
Rates of diabetes continue to rise. According to the authors of this new study, conventional treatment is limited by progressive β-cell dysfunction, poor adherence to therapy because of complex regimens, adverse effects and inadequate long-term efficacy. These limitations have led to increased interest in natural, herbal remedies. Much research suggests that cinnamon is one promising herb to look to.
This new double-blind study gave a placebo or either 250mg or 500mg of cinnamon extract to type 2 diabetics. Cinnamon has compounds that seem to mimic insulin. The form of cinnamon used was Cinnamomum zeylanicum, also known as Ceylon cinnamon or true cinnamon.
The cinnamon significantly reduced fasting plasma glucose and HbA1c, showing that cinnamon improves glycemic control. Cinnamon also significantly reduced insulin resistance and significantly improved β-cell function. These are important results.
The 500mg dose of cinnamon also significantly lowered total cholesterol and the dangerous LDL cholesterol.
This study shows that supplementing cinnamon extract significantly improves glycemic control, insulin resistance and even β-cell function while improving cholesterol in type 2 diabetics.

The Evidence that Boswellia Helps Osteoarthritis Keeps Piling Up

Boswellia is emerging as one of the best treatments for osteoarthritis. This new study adds to the evidence.
Studies are piling up that show that boswellia is not only one of the best ways to improve the symptoms of osteoarthritis (Nutrients. 2025;17(15):2547) but that it can actually help reverse the disease (Phytother Res. May 2019;33(5):1457-1468; J Am Nutr Assoc. 2024 Dec 19:1-12).
This new double-blind study compared a standardized boswellia extract to a placebo in 150 adults with early stage knee osteoarthritis. The study lasted 90 days. The boswellia performed significantly better.
Scores on the WOMAC osteoarthritis index improved significantly at 30, 60 and 90 days. Sub-scores for pain, stiffness and function as well as the people’s rating of their pain significantly improved at 60 and 90 days. The function index also improved significantly.
TNF-α and hs-CRP, markers of inflammation, improved significantly at day 90.
The boswellia achieved all of this safely, again recommending it as a safe and effective option for osteoarthritis.

Flavonoids Found in Berries Improve Cognition

There is more and more evidence that healthy diet can reduce the risk of cognitive decline and dementia. Recent research has suggested that getting more anthocyanins, a kind of flavonoid antioxidant, in your diet can prevent cognitive decline. This meta-analysis put the claim to the test.
Anthocyanins are plant flavonoids abundantly found in red, blue and purple fruits, vegetables and flowers, including blueberries, strawberries, blackberries, grapes, cherries, red cabbage and eggplant.
This brand new meta-analysis includes 59 controlled studies that evaluated anthocyanins in the diet or anthocyanins taken as supplements. Most of the adults in the studies were older.
The results show that anthocyanins significantly improve general cognition, including, specifically, improved visuospatial processing/reasoning and attention, processing and psychomotor speed, verbal speed and fluency, episodic memory, and working memory. That is, they help everything!
The results trended to being better in studies that lasted 3 months or longer, suggesting a benefit for regular, long term consumption.
This meta-analysis supports the evidence that eating more anthocyanin rich berries and taking anthocyanin supplements is associated with better cognitive function and slower cognitive decline.

Want to Keep Your Mind & Body Young? Take Your Multi!

This massive study of 12,666 women who were 65 or older and 8,776 men who were 60 or older found that taking a multivitamin slowed cognitive aging by about 60%, which translated to about 1.8 years over the 3 year study.

It found that, compared to a placebo, taking a multivitamin improved memory by the equivalent of 3.1 years.

The study also found that taking a multivitamin for 2 years can slow biological aging by a significant 10-20%.

Did You Know You Can Improve Your Cholesterol With A Little Black Seed?
This tiny black seed can safely improve your cholesterol.
Black cumin (Nigella sativa), also known simply as black seed, can safely improve your cholesterol according to this just published study.
Black seed is a powerful herb with a multitude of uses. This new double-blind study set out to confirm its benefits for cholesterol. It gave either no treatment or 5g of black seed powder a day for 8 weeks to people with borderline and high cholesterol who were not being treated with medication.
The black seed was able to significantly lower total cholesterol, the heart harmful LDL cholesterol and triglycerides while significantly increasing the heart healthy HDL cholesterol: everything you would want a cholesterol treatment to do. Actually, there’s one more thing you would want it to do: you would want it to do all this safely. The black seed did that too. There were no adverse effects.
This study adds black seed to the list of herbs that can safely improve cholesterol.

New Help for People with Fibromyalgia
Fibromyalgia is a common, but still too little discussed, condition characterized by chronic, widespread musculoskeletal pain, sleep problems, fatigue, mental distress and cognitive impairment. This new study suggests a safe, natural solution that might help.
Fibromyalgia affects between 2% and 8% of all people and probably about 2%-3% of people in the United States and Canada. For some reason, fibromyalgia favours women: in adults, women are twice as likely to have fibromyalgia, making it the most common cause of generalized musculoskeletal pain in women.
Like so many pain conditions, modern medicine has struggled to offer help. Several drugs are used, but they have failed to demonstrate significant benefit and come with risks of adverse events.
This new study looked at the effect of adding Acetyl-L-Carnitine to the medications of 137 people with fibromyalgia. The dosing started with an intramuscular injection of 500mg a day for 10 days and then switched to an oral dose of 500mg twice a day for 20 days followed by a maintenance dose of 500mg a day for 14 months.
The primary outcome the researchers were studying was the person’s evaluation of pain on a Visual Analogue Scale (VAS). The improvement with Acetyl-L-Carnitine was significant. The VAS ranges from 0 (no pain) to 100 (worst pain). When Acetyl-L-Carnitine was added, scores dropped from 75.9 to 59.6.
Acetyl-L-Carnitine also significantly improved quality of life, according to Fibromyalgia Impact Questionnaire—Revised (FIQ-R) scores. The higher the FIQ-R score the worse the quality of life. Taking Acetyl-L-Carnitine improved scores from 75.1 at the start of the study to 53.5 at the end. This improvement represented a transition in severity level from severe to moderate.
The Short Form 12 (SF12) score measures physical and mental health status. There was significant improvement on both with Acetyl-L-Carnitine.
This study suggests that adding Acetyl-L-Carnitine can safely and dramatically improve quality of life in people with fibromyalgia.

Saw Palmetto Helps Hair Growth in Men & Women

The science is quickly building supporting the use of saw palmetto berry extract to reduce hair loss and enhance hair growth in both men and women. This new study adds to the growing evidence.
Though often thought of as a male problem, thinning hair is a big problem for women too. 80% of men will experience male pattern hair loss by the age of 80; 40% of women will experience female pattern hair loss by the age of 50.
This new study included 30 men and 30 women. They were all between 25 and 65. 20 of them were given a placebo for 90 days, while the other 60 were give a saw palmetto berry extract containing 160mg of concentrated bioactive fatty acids.
Digital imaging of a 1 cm2 target site on the front of the scalp and on the back of the scalp allowed the researcher to actually measure how many hairs were gained or lost.
At the end of 90 days, while the people in the placebo group lost an average of 2.7 terminal hairs in the front target site, the people in the saw palmetto group increased by 11.3 terminal hairs. In the back the difference was a 0.5 hair gain in the placebo group versus a 12.1 gain in the saw palmetto group. Terminal hairs are the thick, fully developed hairs. The difference between the 2 groups was significant.
Women who are premenopausal or menopausal experience hormonal changes that affect hair loss and hair growth. But this study found that the 15 women in the study who were in this subgroup had a significant 7.7% increase in terminal hairs at the front of the scalp. They also had a significant 70.7% reduction in hair shedding.
The study also found that saw palmetto berry group shed significantly fewer hairs in the hair pull test than the placebo group.
Importantly, especially when you consider the pharmaceutical treatments for hair loss, the saw palmetto was safe: there were no adverse events.
This study adds to the evidence that saw palmetto berry extract safely and effectively reduces hair shedding and promotes hair growth in both men and women.

Vitamin D and Not Dying of Pneumonia
Pneumonia is a leading cause of hospitalization and death, and the challenge gets bigger as you get older. New research suggests that many of those deaths can be prevented by just getting enough vitamin D.
Community-acquired pneumonia can be caused by bacteria, viruses and fungi. The leading bacterial causes are S pneumoniae and H influenzae. Some of the leading viral causes are rhinovirus, influenza and COVID.
It is a very common concern that increases with age. Pneumonia is the eighth leading cause of death in the world and the leading cause of infectious causes of death.
Previous research has shown that vitamin D deficiency increases the risk of community-acquired pneumonia. It has also been associated with a higher risk of being hospitalized, greater severity, greater risk of ICU admission, length of hospital stay and death.
This well-designed study put the latter to the test, examining whether sufficient levels of vitamin D could protect people hospitalized with community-acquired pneumonia from dying.
514 people were included in the study. The average age was 74. The 90 day mortality rate was 15.7%, and the 180 day mortality rate was 19.1%.
People in the study were considered to have sufficient levels of vitamin D if they were 50 nmol/L or greater, insufficient if they were 25-49 nmol/L, and deficient if they were below 25 nmol/L.
Remarkably, compared to people with sufficient levels of vitamin D, those with a vitamin D deficiency were a significant 3.5 times more likely to die within 90 days and a significant 3.27 times more likely to die within 180.
This study suggests the exciting possibility that maintaining healthy levels of vitamin D can significantly protect people from dying from pneumonia.

Can Resveratrol Improve Cholesterol?
Can resveratrol improve cholesterol? It can if you take enough, as this new study found out.
Resveratrol is a polyphenol similar to flavonoids. It is found primarily in the skin of grapes and mulberries as well as in dark chocolate, raspberries, blueberries and peanuts. Resveratrol in supplements usually comes from the herb Japanese knotweed.
This meta-analysis of 17 controlled studies, which included 968 people, found that resveratrol significantly reduces total cholesterol, heart harmful LDL cholesterol and triglycerides.
An analysis of the effect on LDL cholesterol found that the benefit kicked in at a dose of 500mg a day or more and in studies that lasted 12 weeks or more. Resveratrol had a stronger effect on reducing LDL cholesterol in people with type 2 diabetes.

Cut Your Risk of Heart Attack by Half!
Studies have shown that low levels of vitamin D are linked to worse heart health. But you won’t believe how much getting enough vitamin D can help!
A research abstract (Abstract 4382525) presented at the 2025 American Heart Association Scientific Sessions has revealed for the first time how much getting just enough vitamin D can help prevent a heart attack.
The study included 630 people with acute coronary syndrome who had had a previous heart attack. Each person in the active group took enough vitamin D to reach an optimal level for heart health of 40-80 ng/mL.
Surprisingly, over 85% of the people in the study had levels of vitamin D below 40 ng/mL. Half the people in the study needed more than 5,000 IU of vitamin D just to get their levels up to where they should be.
People in the study were divided into two groups: the first received standard care, and only the second received the vitamin D. The study lasted almost 4 years.
Although 18.4% of the heart attacks, heart failure hospitalizations, strokes or death occurred in the standard care group versus only 15.7% in the vitamin D group, the difference did not reach significance.
But, when the researchers looked specifically at heart attacks, they found a 52% lower risk in the vitamin D group.
This study suggests that making sure you have optimal levels of vitamin D could be an important strategy for preventing a second heart attack.
More research is needed because research abstracts have not yet been peer-reviewed or published.

A Traditional Men’s Herb Proves It Can Take on Menopause
Tongkat ali (Eurycoma longifolia) is a Southeast Asian herb that has been traditionally used in Malaysia as an adaptogen for general well-being. As one of its popular names, longjack root, suggests, it is best known as a powerful aphrodisiac for men. But tongkat ali just expanded its resume. This new study shows that it is also a powerful herb for menopause.
This new double-blind study gave women with menopausal symptoms either a placebo or 100mg of tongkat ali extract for 12 weeks.
On the MENQOL assessment, total score improved significantly more in the tongkat ali group than in the placebo group. The tongkat ali group improved by 33.9% versus 23.3%. The herb group had a significantly greater improvement in the physical and sexual domains.
Women taking tongkat ali had a 33.4% improvement in hot flashes and night sweats, a 36.4% improvement in physical symptoms, a 36.3% improvement in sexual symptoms and a 26.8% improvement in psychological symptoms.
On the POMS assessment of psychological symptoms, including tension, depression, anger, fatigue, vigor, and confusion, total score improved more in the tongkat ali group than in the placebo group: tension improved by 21.7%, depression by 31.9%. anger by 13.8%, fatigue by 36.9%, confusion by 20.5% and vigor by 5.7%.
Tongkat ali was safe, with no adverse events, no effect on hormones, blood pressure, liver enzymes or kidney function, an important possible advantage over hormone therapy.
This is the first study to show that tongkat ali, which is traditionally used as a male aphrodisiac, is also an important herb for women that can safely help with menopause.

Moringa Helps People with HIV
Around 38 million people around the world are living with HIV. Around 650,000 die every year. Despite antiretroviral therapy, many people still have suppressed immunity, low platelets, malnutrition and low body mass index. Progress has been made, but more help is needed. Meet moringa.
Moringa oleifera is common in the Middle East, Africa and Asia. It is loaded in nutrients and has been found to improve immunity and nutritional status. This systematic review and meta-analysis of 8 studies set out to see if it could help people with HIV.
HIV primarily depletes CD4+ T cells, causing suppressed immunity and leaving the person vulnerable to opportunistic infections. CD4+ count is a key indicator of immune function and is used to monitor the progression of the illness and the effectiveness of the treatment. Moringa significantly increased CD4+ count.
White blood cell counts and platelet counts were also significantly higher in the group supplementing moringa than in the control group, both suggesting improved immunity.
Moringa was also able to significantly improve BMI. This ability is important because people with HIV often struggle with malnutrition, both from the disease and from the toxicity of the drugs. The resulting low BMI diminishes overall health and quality of life and increases the risk of comorbid conditions.
Importantly, the study also confirmed the safety of supplementing moringa.
This study found that moringa could safely improve immunity and nutrition in people with HIV, hopefully improving health and quality of life.
