Vitamin D and Aging

This study looked at 2 age groups; 55 to 65 (725 people) and 65 to 88 (1237 people). The idea was that since vitamin D is directly connected to muscle health, would the resulting decrease in muscle affect people’s ability to do normal things like; dressing, walking up or down stairs, cutting their toenails, standing from a sitting position, driving their car, or walking for 5 minutes.


After factoring for things like age, physical activity, and chronic disease, they looked at two vitamin D subgroups… those with vitamin D blood serum levels <20 ng/ml (deficient) and >30 ng/ml. The vitamin D deficient folks from both age groups had significantly greater number of physical limitations after the follow-up period (3 years for the older group and 6 years for the younger group).


It’s very common for people, especially the further north you live, to be under 20 ng/ml. Even if you are taking a vitamin D supplement, you should be tested.


If you’re still not paying attention to your Vitamin D levels…

With the overwhelming amount of information and misinformation being thrown at us on a daily basis, especially in regards to our health, how do we figure out what we really need to pay attention to?  One expert will sound the alarm and then the next will cry BS.  We’re left confused and frustrated... plus if everything is so important, then nothing is, right?  

My goal is to wade thru the clutter and highlight topics and research that matter to your optimal health.  With that said, science is showing that VITAMIN D is one thing we all need to pay attention to for 2 reasons... it’s critical to our health and about half of us are deficient.


Below are 5 critical points on vitamin D and 1 outstanding non-profit project we can all participate in to battle the problem.

  1. Our bodies are designed to produce vitamin D from sun exposure.  Most of us are spending more and more time indoors and when we are outside, we’re either covered...

What’s the Difference Between a Tomato and a Tomato? (Fab Five, Part 5)

Multiple Vitamin - Come On, We All Knew It Was Making The List
  There are several reasons why we all NEED to be taking a good multiple vitamin...   Where It’s Grown - It’s easy to think of soil as just the dirt where plants take root, but it’s so much more. The nutrients in the foods we eat are directly linked to microbe activity, organic matter, the mineral composition, plant genetics, and fertilization practices.  The tomato might look much the same as it did 80 years ago, but it’s not.  Average mineral content in selected vegetables, 1914 - 1997. Or your apple... Eighty year decline in mineral content of medium apple. The type of soil matters too, for example, vegetables grown in clay dense soil can have 5 times the nutrients as those grown in sand dense soil.

Vitamin D (Fab Five, part 4)

The “Fab Five” is not necessarily in the order of importance, but if it was, then this one would make a good run to hold the number one spot. Everyone associates Vitamin D with Rickets due to the role it plays in our ability to absorb calcium, but it does so much more. Here are just a few things Vitamin D deficiencies have been associated with (autoimmune diseases, weight gain, hypertension, psoriasis, eczema, insomnia, hearing loss, muscle pain, periodontal disease, athletic performance, age related macular degeneration, myopia, pre eclampsia, seizures, fertility, asthma, cystic fibrosis, migraines, depression, alzheimer’s and schizophrenia).

Some very good studies have shown that Vitamin D may reduce the risk of developing certain types of cancers such as breast, colon and prostate. If you’re a geek like I am, then give this study a read ( They looked at 3 million incidents of cancer and 3 million cancer deaths, and compared that against UV-B exposure by location.   Vitamin D...

Widespread Deficiencies in Vitamin D Bring Cloudy Days

Vitamin D is the sunshine vitamin. It is produced in our skin when we are in sunlight and, in fact, we actually get very little of this vitamin from the food we eat. As a result, you might think that it is one of the last vitamins we should be worrying about when it comes to deficiencies of nutritional substances; however, a recent report shows that worldwide more and more people are suffering from low levels of this vitamin. The consequences of deficiencies are significant. This particular vitamin works together with calcium and is important, not only for keeping our organs in peak condition, but also for the normal development and strength of bones. Low levels of the vitamin in adults can increase the risk of osteoporosis and hip fractures. In children, it can lead to rickets which is where the bones become soft and can fracture or even become deformed.

This recent research was undertaken by the expert working group of the International Osteoporosis Foundation (IOF) and was published in Osteoporosis International. In the study, the group researched the incidence...

Know Vitamin D…No Cancer

Vitamin D is one of the fat soluble vitamins that research published in July 2009 states may have cancer suppressing properties. Various forms of the vitamin have been discovered each with many similar properties and benefits. In addition to their common effects, the variants have been found to play specific roles in the body. The two main variants in humans are D2 and D3. It often is referred to as the sun vitamin because exposing the skin to direct sunlight allows the body to absorb and create the vitamin in necessary quantities. As people age, their requirement for it increases, as does the requirement for supplementation for those with limited sun exposure. Many foods are now supplemented with a form of the vitamin in order to help prevent deficiencies. These fortified foods may be in milk products, cereals, grains, juices, and are also naturally present in fatty fish, and mushrooms that have been exposed to radiation. In fact, the Sun Bella is a new form of mushroom that has USDA clearance and provides a considerable amount (400 IU) of the vitamin. Because the body stores...

The Must of Multivitamins in Pregnancy

Recent estimates indicate that every year about 20 million babies are born with a low birth weight. This is around 15.5 percent of the total number of annual births - which has been estimated to be 133 million. With such a significant number of newborns exposed to the negative effects of a low birth weight, finding preventative measures is of great importance. The latest research has indicated that if all mothers took multivitamins during pregnancy it may be possible to reduce the incidence of low birth weights by 17 percent. Dr Prakash Shah and his team from Mount Sinai Hospital, Toronto, recently reported on these global statistics and the potential of this dietary supplementation following work in which they collated research from 15 separate studies on this topic worldwide. These findings are not conclusive as there are too many varying factors between the studies such as, study duration, differences in the supplements provided, participant groups and the timing; however, they are significant.

Vitamin D Tops for Reducing the Risk of Fractures in Older Adults

Recent studies have shown that older adults can reduce the risk of non-vertebral (non-spinal) bone fractures by as much as 20% and that of hip fractures by up to 18% by taking vitamin D supplements. Although there have been several clinical trials around this possibility in the past, it is only a recent meta-analysis that has provided conclusive evidence of the link. (A meta-analysis is where the results of several studies on a related topic are combined.) Up until now, a number of factors have hindered acceptable findings, namely: participants not following the required treatment program, the use of a different form of the vitamin (ergocalciferol, or vitamin D2) which is weaker, or the use of doses that are too low to be effective. The meta-analysis was based on previous studies which had looked at the benefits of oral supplements of the vitamin in adults upwards of 65 years old. There were 12 studies with a total of 42,279 subjects where the average age was 78 years. 40,886 of these were considered specifically for hip fractures. In each case neither the participants nor the researchers were aware...
