Older people experiencing a decline in their memory at a relatively earlier
age can benefit from a daily Chromium Picolinate (CP) supplement. In this new
study presented recently at a peer-reviewed medical conferences older adults
with an average age of 72.5 years were given either 1000 mcg of CP a day or
inactive placebo for 12-weeks. The double-blinded study was performed at the
University of Cincinnati. Functional magnetic resonance imaging measured their
brain activity while the participants worked on a challenging cognitive task
that involved holding in mind and manipulating visual information. The MRI showed
improved function in parts of the brain involved with organizing information,
coordination, speech and touch, memory, attention and language. The study result
was presented at the 19th Annual Meeting of the American Neuropsychiatric
Association.
Having sufficient Vitamin K improves the bone strength of adolescents
and may decrease the risk of fracture later in life
Having a sufficient level of vitamin K improves the bone health of adolescents
and this better status may protect them from osteoporosis later in life, suggests
a new study. An improved status of the vitamin was found to improve bone mineral
content and bone mass in the whole body, according to the study of 307 healthy
children with an average age of 11.
"As children grow the increase in bone mass may fail to keep up with the
increase in height, or length of the bone, and as a consequence, this imbalance
may result in fracture," said lead author Marieke Summeren from University
Medical Centre Utrecht. "But the main threat of a long-term shortage of
K vitamins is that peak bone mass may be compromised, and as we age and begin
to lose bone density, the risk of fracture in later life is increased."
About 35 per cent of a mature adult's peak bone mass is built-up during puberty.
The new study followed the children for two years and correlated vitamin K status
to bone mineral content (BMC) and markers of bone metabolism. Large variations
were observed in the vitamin K status of the children, both at the start and
end of the two-year study. An improved vitamin K status over the time period,
as was observed in 281 children, was associated with a significant increase
in BMC.
The research adds to a growing body of science linking the vitamin to improved
bone health, particularly in post-menopausal women. The Maastricht-based researchers
previously reported that daily supplements of vitamin K2 maintained hipbone
strength in postmenopausal women, while placebo was not protective and bone
continued to weaken. The double-blind, placebo controlled study followed 325
healthy women with no initial osteoporosis for three years and also found that
vitamin K2 supplements boosted the women's bone mineral content compared to
placebo. That study was published in Osteoporosis International. The new study
is published online ahead of print in the current issue of the British Journal
of Nutrition.
