This week, Dr. Oz brought us some tips to help with memory, blood pressure and bone strength. Read on to find the real info behind the good doctor's suggestions.
Vinpocetine: An Extract Of Periwinkle
According to a 1999 study published in the Alternative Medicine Review, vinpocetine may be most useful for the kind of memory problems and dementia found in people whose blood vessels don't bring enough enough blood to their brains.
This type of memory problem is called vascular dementia. Vascular dementia is a common type of dementia and can happen after a stroke, when a blood vessel becomes blocked, or when the aging process, high blood pressure, or atherosclerosis act to narrow blood vessels in the brain.
Vinpocetine dilates blood vessels in the brain, providing hungry brain cells with oxygen. In a study published in the Journal of the American Geriatric Society, vinpocetine improved learning, memory, and global measures of brain performance in people with mild to moderate vascular dementia.
Dr. Oz says the dose is 10mg three times per day.
Hawthorn For Blood Pressure and Cholesterol
Hawthorn may be beneficial for high blood pressure as well as high cholesterol. In a 2006 study, hawthorn lowered blood pressure in a group of diabetics. In a different study with animals, hawthorn performed better than a statin drug in lowering cholesterol when the animals ate a high cholesterol diet.
Dr. Oz's recommended dose is 150mg three times daily.
AlgaeCal: The Super Calcium
AlgaeCal is literally calcium made from Algae. It is better for bones than rock based calcium, as Dr. Oz pointed out. Another name for rock based calcium is calcium carbonate. Caltrate is a well known brand of calcium carbonate. Unlike calcium carbonate, AlgaeCal is porous with many tiny holes and extensive surface area, allowing for easier digestion.
Many calciums, like the calcium carbonate Dr. Oz talked about, take lots of stomach acid to digest. Not everyone has this much stomach acid, especially as we get older. This fact alone accounts for much of the difference in calcium absorption rates.
The bone density research with Algae Cal is promising. A University of Texas study involving postmenopausal women recorded a 2.18% gain in bone density within 6 months of using AlgaeCal.
Vitamin K2 is a new player on the bone density field. Vitamin K2 is different from from the regular vitamin K (vitamin K1), which pertains mostly to blood clotting. K2 is a boon for bone density because it turns on proteins that remove calcium from the wrong places, like artery walls, and helps deposit calcium in the right places, like bones. It promotes bone building and slows bone loss.
Vitamin K2 is beneficial both from a bone and a cardiovascular standpoint. Researchers found that 45mcg MK-4 type vitamin K2 prevented additional fractures in patients with osteoporosis.
Vitamin D is a huge factor for bone density. Vitamin D deficiency is very common and low levels are linked to poor bone density.
