Why Vitamin K2 is So Important for Your Kids
Great new for parents who buy Kids Potential …
We added Natural Dairy & Casein-Free Vitamin K2, as MK-7, to Kids Potential for healthy bone density to help them develop healthy, strong bones beginning early in life. Here is a re-post of relevant scientific research that gives you some idea of why Vitamin K2 is an important nutrient for your growing children.

=========================
Findings of a new study published in British Journal of Nutrition 2009 by van Summeren and colleagues demonstrated that even modest supplementation with menaquinone-7 in children increases activation of osteocalcin, the bone-building protein; and in that way supports healthy bone growth and development. This is an important finding as the greater bone mineral established during childhood and early adult years, culminating in peak bone mineral density around 30 years of age, allows for better maintenance of bone health as we age and lose bone mass.
The present study is a double-blind randomized placebo-controlled study examining the effect of 45 mcg natural vitamin K2 as menaquinone-7 (MK-7) on the circulating levels of the vitamin K-dependent protein Osteocalcin. Active osteocalcin is required for bone-building cells (osteoblasts) to optimally utilize calcium for building and maintaining a healthy bone matrix. 8 weeks of supplementation in healthy prepubertal children increased blood levels of vitamin K2 as MK-7 and significantly increased the amount of active osteocalcin.
According to Professor Cees Vermeer at the VitaK research center, “Non-supplemented people are generally insufficient in vitamin K. It has been demonstrated that children are far more vitamin K deficient than adults. We explain this by the rapid growth of their bones and consequently the high vitamin K demand by the bones for the production of osteocalcin. The present study is the first one to demonstrate that increased vitamin K intake by supplement improves the osteocalcin activity in children. The next step must be that also an effect of MK-7 on bone strength or fracture risk is demonstrated in this age group. There is a growing awareness that maximizing bone strength at childhood is an important strategy to prevent osteoporosis at later age.”
Osteocalcin – the potent protein
Osteocalcin is a protein responsible for utilization of calcium within bone tissue – it has the ability to bind calcium to the matrix of bones, which makes them stronger and less susceptible to fractures. Without sufficient amounts of vitamin K in the diet, or in cases of Vitamin K deficiency, inactive osteocalcin is not able to bind calcium properly, and thus the bones weaken and become fragile.
Strong bones – best investment for the future
Children have the greatest requirement for active osteocalcin and thus for K vitamins because bone tissue grows and develops most intensively during childhood and adolescence. The higher peak mass young bones achieve, the lower the risk of osteoporotic changes in the elderly. Hence, the optimal pubertal status of bone is important to prevent disorders in later life.
Benefits scientifically proven
Results of the new study clearly confirm outcomes of previous laboratory experiments, population-based (i.e., epidemiological) studies and clinical trials that have tightly linked better vitamin K status in children to the achievement of a healthy, strong bone-structure. Simplified, improving vitamin K status in children results in stronger and denser bones. Additional K vitamins intake might also improve bone geometry and positively influence gain in bone mass. That contributing effect has been recently reported by O’Connor et al , who, while conducting a study in a cohort of 223 healthy girls (11-12 years old), found better K vitamin status related to higher bone mineral density.
Warfarin, a commonly prescribed blood-thinning medication, inhibits vitamin K activity. A study of children with long-standing vitamin K deficiency induced by this drug were shown to have a significantly reduced bone mass, which illustrates the potential consequences of K vitamins deficiency in growing bones.
Best Time to Take Vitamin D
Did You Know…
Taking your vitamin D supplement with your largest meal of the day may boost its uptake by as much as 56%!
This finding was presented in a study published in the April 2010 issue of the Journal of Bone and Mineral Research.
Adequate vitamin D levels are linked to a reduced risk of osteoporosis.
Alcohol & Bone Health
1/2 A Drink May Help Your Bones
Moderate drinking of alcohol may support bone health, according to a May, 2008 study reported in the American Journal of Medicine.
Participants who had more than half a drink, but no more than one full drink, per day had a 20-percent lower risk of hip fracture than teetotalers.
Moderate amounts of alcohol help bones in two ways: by boosting estrogen, which also increases calcium absorption.
Bone Health: Are Calcium & Vitamin D Enough?
“The WHI CaD” study is the largest randomized clinical trial conducted on calcium supplementation in post-menopausal women. It followed over 36,000 women for ~7 years. Half of the women took 1,000 mg of Calcium and 400 IU of Vitamin D; the other half took a placebo.
RESULTS: Women taking placebos had a hip fracture rate of 14/10,000. Women taking calcium and vitamin D had a hip fracture rate of 10/10,000. While the trend is favorable, the message of the study is that calcium and vitamin D are not enough, according to Dr. Joel Finkelstein, an osteoporosis researcher at the Massachusetts General Hospital in Boston. “It is a good start, but women at higher risk need to know it is not enough.”
Dr. Joel Finkelstein:
“With widespread marketing calcium & vitamin D, many women believe that they are completely protected against the development of osteoporosis if they are taking these supplements. This study should help correct this important misconception and allow more women to receive optimal therapy for bone health.”

Suggestions for Optimal Bone Health
The Importance of Natural Vitamin K2 (MK-7)
Researchers investigated why women in the Eastern part of Japan had much lower incidence of hip fracture vs. women who lived in other parts of Japan. It came down to a Japanese traditional food consumed only in the region where women had very low incidence of hip fracture – a marker in medicine for bone density.
Natto.
Natto is a traditional Japanese fermented soybean dish commonly consumed in Eastern Japan. Natto is a fermented, soybean cheese-like dish that has a very strong amoniacal smell with a gluey texture and spiderweb-like strings when you stir it. So what does Natto have to do with bone density?
Vitamin K2, specifically, Menaquinone 7 (MK-7)
Researchers report Natto contains natural Vitamin K2, specifically Menaquinone 7 (MK-7) that is linked to stabilization of bone proteins, positively impacting bone density. Not only is Natural Vitamin K2 (specifically MK-7) important for healthy bones, scientists discovered that MK-7 supports cardiovascular health as well. The growing body of Vitamin K2 research indicates that it is a very promising nutrient for supporting healthy bone density.
