Can you really add Vitamin D to your sunscreen and expect it to get to work?

In short I’m not sure that anyone knows really as while we do understand a fair amount about where this vitamin comes from and goes to I feel we are far from having all of the answers. But as usual, that doesn’t stop skin care brands taking a punt and why shouldn’t they……

Anyway, I recently purchased this:

Vitamin D3 is the stuff that the skin makes upon UV irradiation.  I didn’t know this until May 2012 when I researched it a whole lot for a talk I gave at a Malaysian University gathering.  Part of that research is available here.

As you would have noticed if you flicked to the link, our skin doesn’t have a vitamin D3 reservoir, instead it makes 7-Dehydrocholesterol in the basal layer which, when irradiated forms Vitamin D3 which then goes into the bloodstream and does its stuff.

That is one reason why I have my doubts about topically applied Vitamin D3. Maybe the conversion is significant and it is the conversion that kick starts the biological conveyor belt rather than assuming the presence of the ‘key’ which in this case would be Vitamin D3 produces the ‘door’ or transport mechanism?  At this point in time I have no idea how significant or not that subtle detail is.

Another of my reservations centres on the fact that vitamin D3 has a short half-life and therefore must may hay while the sun shines so to speak! Transdermal delivery can take time.

A third centres on the fact that I haven’t been able to find any scientific paper as yet showing that topically applied Vitamin D3 will increase circulating Vitamin D levels and while that doesn’t mean that none exist it does add to my doubtful […]

The Beauty Of Hydration

Guest Post by Jenny Dean (owner and operator of

We all know the importance of hydration, not only as an overall detoxifier but also as a weight maintenance agent. The human body is about 60% water. 75% of that 60% are your muscles and brain, blood is 82% water and bones are 25% water. That’s a lot of body water!

We need to consume a lot more water than we do. In fact, many of us are chronically dehydrated. Often times our thirst mechanism that tells us when we are dehydrated is often mistaken for a feeling of hunger. So next time you are between meals and are hungry, reach for a glass of water and see if that doesn’t curb your hunger.
Why Hydrate?
A study at the University of Washington found that even if you are suffering from mild dehydration, your metabolism can be slowed down by as much as 3%. Here are some other great reasons to hydrate!

1 glass of water can eliminate midnight hunger
Dehydration is the first trigger for daytime fatigue
Hydration can relieve joint pain
Hydration helps to reduce bladder infections
Hydration helps to eliminate waste in the body
Dehydration triggers fuzzy-short term memory trouble with basic math
Hydration reduces the risk of colon cancer by 45%
Hydration reduces the risk of breast cancer by 79%
Hydration reduces the risk of bladder cancer by 50%

Are familiar with the knowledge that you can go weeks without food, but only days without water? The reason is because water is a necessity for basic physiologic functions, like our blood pressure, body temperature, hydration and digestion. The human body needs 1.5 milliliters of water to absorb each calorie ingested.
8 Glasses a Day?
We’ve all heard that we should have 8 glasses of water a […]
