Curcumin found to provide benefit even in the healthy. This study, though small and very short, found improvement in Triglycerides, salivary amylase, reduced oxidative stress, reduced beta-amyloid protein, increased NO, and reduced liver enzymes.
Huperzine A is a great neuroprotector. Huperzine A is a acetycholinesterase inhibitor. But, Huperzine A also reduces oxidative stress, reduces beta-Amyloid, protects mitochondria, antagonizes NMDA receptors and thus reduces excitotoxicity, and regulates apoptosis.
myloid plaques and microgliosis in the brain of Alzheimer’s mice fed
with GSE were also reduced by 49% and 70%, respectively
Curcumin also significantly reduced brain Aβ burden and microglia
activation
polyphenol-rich GSE prevents the Aβ deposition and attenuates the inflammation in the brain of a
transgenic mouse model, and this thus is promising in delaying development of AD.
Inflammation plays an important role in Alzheimers disease. Likewise, the ability to resolve inflammation is altered, as this study shows. This points to natural therapies i.e. omega-3, curcumin, vitamin D...
This review summarizes new insights based on the interaction of mitoenergetic failure, glutamate excitotoxicity, and amyloid
toxicity in the exacerbation of AD.
vitamin C deficiency is the fourth most prevalent nutrient deficiency reported in the United States
Hypovitaminosis C (defined as a plasma concentration ≤23 µmol/L)
The CHALICE (Canterbury Health, Ageing and Lifecourse) study is a unique New Zealand study comprising a comprehensive database of determinants of health
The CHALICE cohort of 404 individuals aged 50 years had an average vitamin C intake of ~110 mg/day, which should provide adequate plasma concentrations [14]. Despite this, a significant proportion of the participants had inadequate plasma vitamin C status
inadequate plasma vitamin C concentrations (i.e., <50 µmol/L)
adequate plasma levels (i.e., >50 µmol/L)
Higher plasma vitamin C status was associated with lower weight, BMI and waist circumference
plasma vitamin C was negatively associated with blood triglycerides, HbA1c and insulin, and positively associated with HDL levels.
No correlation was found between plasma vitamin C and the two indicators of heart health; blood pressure and cardiovascular risk score.
2.4% of 50-year-olds were deficient in vitamin C (i.e., <11 µmol/L)
hypovitaminosis C (i.e., <23 µmol/L)
A high proportion (63%) of our participants had inadequate plasma vitamin C concentrations (i.e., <50 µmol/L)
The association of low vitamin C with obesity in this study replicates results in the literature [35,40,41,42,43,44], and it is apparent that individuals with higher weight require higher intakes of vitamin C to reach adequate vitamin C status
higher plasma vitamin C status is associated with lower circulating levels of blood triglycerides, insulin and HbA1c
A role for vitamin C in the prevention or management of diabetes and/or metabolic syndrome has been suggested
In this study, we also demonstrate lower levels of mild cognitive impairment in those with high vitamin C status
The odds of mild cognitive impairment were twice as high for those below 23 μmol/L plasma vitamin C concentration.
Vitamin C is present at very high concentrations in the brain
animal models have shown that the brain is the last organ to be depleted of the vitamin during prolonged deficiency
A recent animal study has shown that moderate vitamin C deficiency may play a role in accelerating amyloid plaque accumulation in Alzheimer’s disease
New study: vitamin C levels correlate with cognitive and metabolic health. What is your vitamin C level? Despite the adequate levels of vitamin C intake, a large % of the individuals had inadequate vitamin C levels which points to a demand issue. Higher oxidative stress, chronic inflammation... would drive demand for vitamin C higher. Lower vitamin C levels were associated with more metabolic disease, ie. DM, and more cognitive decline.
