Silica as OSA in Water can Reduce Alzheimer’s Risk

Silica as OSA in Water can Reduce Alzheimer’s Risk

French researchers have reported that higher levels of aluminium in drinking water appears to increase people’s risk of developing Alzheimer’s disease, whereas higher levels of silica (OSA) appear to decrease the risk.

Their latest findings were published in the prestigious Journal of Epidemiology 15 February Issue, 2009 pages 489 – 496. “Aluminium and Silica Intake in Drinking Water and the Risks of Alzheimer’s Disease or Cognitive Decline : findings of the 15-year follow-up PAQUID cohort”.

Dr. Virginie Rondeau at the Institute National de la Sante et de la Recherche Medicale in Bordeaux told Reuters Health that Alzheimer’s Disease is a multifunctional disease and aluminium concentrations in drinking water may have an effect on cognitive decline and Alzheimer’s disease.

Daily aluminium intake of at least 0.1 mg per litre was associated with greater cognitive decline during the course of the study.

Subjects with a high daily aluminium intake had a 2–26-fold increased risk of dementia however for every 10 mg per day intake of silica, the odds of developing dementia or Alzheimer’s dropped by 11 percent.



Previous studies have reported that OSA can reduce the oral absorption of aluminium and enhance aluminium excretion from the body and protect against aluminium-induced adverse effects. In fact in a study, “Non-invasive therapy to reduce the body burden of aluminium in Alzheimer’s disease” published in Journal of Alzheimer’s Disease 10 (2006) 17 – 24, 10 patients with Alzheimer’s Disease (AD) drank 1.5L of an orthosilicic acid (OSA) rich mineral water for 5 days (Si = 14.5 mg/L). Comparisons were made of their urinary excretion of aluminium before and after this simple procedure. Urinary excretion of Aluminium decreased significantly for 8 out of 10 patients. OSA both reduced the gastrointestinal absorption of dietary aluminium and facilitate the urinary excretion of systemic aluminium.

The researchers said the reduction in urinary aluminium supported the future longer-term use of OSA as a non-invasive therapy for reducing the body burden of aluminium in Alzheimer’s disease.

Many other studies have also confirm the benefits of OSA for bone, skin, hair, nail health and with OSA potency in also chelating aluminium, this opens up the potential of OSA as a very important healthy ingredient for our body requirement.

Fortunately, OSA is readily available in Spritzer Natural Mineral Water is rich with OSA and by consuming one litre of Spritzer one can obtain 35 mg of Si (OSA)to improve your health.
