Reduced premenopausal vitamin D levels predict hypertension later in life

Reduced premenopausal vitamin D levels predict hypertension later in life

The American Heart Association's 63rd High Blood Pressure Research Conference was the site of a presentation this month concerning the finding that low vitamin D levels prior to menopause are associated with an increased risk of elevated systolic blood pressure 15 years later. Systolic blood pressure is a measurement of the blood's pressure on the vessel walls when the heart contracts. Systolic hypertension is defined as occurring when systolic blood pressure is 140 mm mercury or higher.

For their research, Flojaune C. Griffin, MPH, of the University of Michigan and colleagues evaluated data from 559 Caucasian women enrolled in the Michigan Bone Health and Metabolism Study. The participants, who were between the ages of 24 and 44 at the beginning of the study in 1992, had their blood pressure measured annually, and serum levels of 25-hydroxyvitamin D were assessed in 1993.

While just 6 percent of the participants had systolic hypertension at the beginning of the study, 19 percent had been diagnosed by 2007 and an additional 6 percent were found to have undiagnosed systolic hypertension. Women who had deficient levels of vitamin D (defined as less than 80 nanomoles 25-hydroxyvitamin D per liter) in 1993 had a three times greater adjusted risk of developing systolic hypertension by 2007 than women with normal levels.

"This study differs from others because we are looking over the course of 15 years, a longer follow-up than many studies," stated Griffin, who is a doctoral candidate in epidemiology at the University of Michigan School of Public Health in Ann Arbor. "Our results indicate that early vitamin D deficiency may increase the long-term risk of high blood pressure in women at mid-life."

Griffin added that recent research has shown an association between the risk of vitamin D deficiency and the development of some cancers and inflammatory diseases. The current recommended daily intake of 400 to 600 international units (IU) has been recommended by some researchers to be increased to 1,000 to 5,000 IU.

High Blood Pressure

Blood pressure is a measurement of the force exerted by blood as it flows through the arteries. High blood pressure occurs when there is an increase of force against the arterial wall, with potentially damaging consequences. Among adults, a normal blood pressure measure is considered to be below 120/80 mm Hg. Any blood pressure reading higher than this reflects elevated blood pressure.

The force of blood pressure is measured in two stages: when the heart is contracting (systolic pressure) and relaxing (diastolic pressure). Blood pressure is always expressed in pressure units of millimeters of mercury (mm Hg), and written as systolic over diastolic pressure. For example, a blood pressure reading of 120/80 mm Hg would mean a systolic pressure of 120 mm Hg and a diastolic pressure of 80 mm Hg.

CoQ10 is found in the mitochondria, which is the energy-producing center of cells. It is involved in making the molecule known as adenosine triphosphate (ATP). ATP is the cell’s major energy source. CoQ10 also serves as an antioxidant. Some studies have suggested that CoQ10 may stimulate the immune system and increase resistance to disease (Folkers K et al 1988), as well as lower blood pressure (Hodgson JM et al 2002). One theory to explain the effectiveness of CoQ10 on blood pressure concerns its role as an antioxidant. Studies of diabetics have found that increased oxidative stress may underlie endothelial dysfunction by decreasing production and increasing consumption of nitric oxide, as well as generating free radicals. CoQ10 has been found to mitigate this effect by reducing oxidative stress, thereby normalizing nitric oxide production and consumption (Chew GT et al 2004; Watts GF et al 2002).

CoQ10 has been widely studied in patients who have congestive heart failure and take hypertensive medications. One study of 109 patients with essential hypertension who supplemented their diets with 225 mg/day of CoQ10 in addition to their hypertensive medication, found that participants gradually were able to decrease the need for drug therapy during the first 1 to 6 months. Fifty-one percent of the participants were able to completely discontinue some of their medications an average of 4.4 months after they began CoQ10 supplementation (Langsjoen P et al 1994).

Natural Esophaguard

add to cart

Constant regurgitation of harsh stomach acids, bile, and food from the stomach into the esophagus can damage the delicate lining of the esophagus and increase the risk of problems of the upper digestive tract.

Natural EsophaGuard is a novel, all-natural solution for gastric distress. Its active ingredient, a standardized extract from orange peel known as d-limonene, has been shown to provide fast-acting, long-lasting relief from gastric distress. D-limonene is thought to coat the esophagus and guard against caustic stomach acid, while helping to reduce the amount of gastric juices regurgitated into the esophagus.

Natural EsophaGuard does not contain potentially harmful compounds such as aluminum, nor does it impair the body’s absorption of critical nutrients such as calcium or shut down production of stomach acids needed for normal, healthy digestion.

Dual-Action Cruciferous Vegetable Concentrate with Resveratrol & Cat's Claw

add to cart

Cruciferous vegetables (broccoli, cauliflower, Brussels sprouts) are a rich source of glucosinolates and their hydrolysis products, including indoles and isothiocyanates. Scientists discovered specific extracts from cruciferous vegetables can modulate female hormones in a way to help maintain healthy cell division and gene expression. Dual-Action Cruciferous Vegetable Extract with Cat’s Claw combines these plant extracts in one convenient, cost-effective formula.

Extracts of broccoli, watercress, and rosemary provide standardized concentrations of glucosinolates, isothiocyanates, carnosic acid, and carnosol — bioactive compounds with favorable effects on estrogen metabolism and cell division.
