Re: Holick & Gilchrest Virtual Debate

"Yes, vitamin D is vital for our well-being but sunscreens WILL NOT completely block your skin from absorbing the proper nutrients. Nor will it completely block the harmful side effects of UVA and UVB rays. That's a proven fact. Not to mention, taking a vitamin D supplement DOES help vitamin D deficiency, and that's a fact. "


You are dropping WIVES TALES little girl. Nothing you are saying is a "proven fact". SPF does NOTHING other than keep you from burning and block Vitamin D production.

FACT is when you YOURSELF has done the experiment and seen the results first hand. YOU have not done this.

I have and can prove it right now.



The SUNDAZZLER is an 11min max booth. You'll notice that in only a 4MINUTE EXPOSURE your body will produce approximately 8500IUs of VITAMIN D3.

By wearing an SPF of only 15 your VitaminD3 production drops to a meager 85IUs. Doctors recommend 1000IUs a day.

Is 85 more or less than 1000?

So if you are trying to say that SPF doesn't block Vitamin D production AND IT'S A FACT, where is your facts? I got mine.

What say you?

Re: Holick & Gilchrest Virtual Debate

Number one, I was kind of joking in my last post I'm sorry people got so emotional over it. Number two, people don't always apply sunscreen properly or evenly and even with sunscreen applied correctly, your body still will absorb vitamin D. Number three, I never once said to avoid the sun nor did I say the sun wasn't healthy for you- IT IS HEALTHY FOR YOU, we all know that. Nor did I comment on the levels of vitamin D you receive with or without sunscreen. I have no idea about the specifics. ALL I WAS stating was that you can still absorb vitamin D while you are wearing sunscreen. Period. That's it. Don't take it so personally and don't over analyze what I was saying.

Just a little side note: Before I got into the tanning industry, I went to esthetician school after HS. I completed the hours, took the exam and I'm licensed. After that I went back to college, I have my bachelor's degree, majored in business management and graduated with a 4.0. Engfant, if you are so concerned on where my facts come from I'll be more than happy to send you my books for references.

I understand what you guys are saying and I'M NOT DISAGREEING WITH YOU! There is truth to what we are all saying here.




Here's a couple articles on the topic:


"Three studies have documented that regular use of sunscreen is not likely to result in vitamin D deficiency." http://findarticles.com/p/articles/m...6/ai_n7550550/


"So is it possible that wearing sunscreen might interfere with the synthesis of vitamin D?

Yes. Studies have found that by blocking ultraviolet rays, sunscreen limits the vitamin D we produce. But the question is to what extent.

A few studies have concluded that the effect is significant -- a reduction as great as tenfold. But more recent, randomized studies that followed people for months and in some cases years suggest that the effect is negligible. Although sunscreen does hamper vitamin D production, these studies say, it is not enough to cause a deficiency." http://www2.mcdowellnews.com/content...sa/lifestyles/

"sunscreens do NOT block all of the UV radiation hitting the skin, so that those wearing sunscreen are still able form vitamin D. There is simply no such thing as a total (or even near total) UV block. Even the most effective sunscreens currently on the market let through enough UV to allow for adequate vitamin D formation. According to Rigel, normal vitamin D levels are easily maintained through routine daily activities (even when wearing sunscreen) and a normal diet. “Supplemental vitamin D tablets are typically not needed,” states the scientist." http://bacteriality.com/2008/01/15/sunscreen/

Relax, I don't take supplements, I own a tanning salon, I tan almost everyday... Trust me, I'm not preaching to stay out of the sun and just pop pills.

You better do that then... because the 3 "articles" (not peer reviewed scientific papers) you linked are pure propaganda. Not "facts". Don't be so gullible!

1. This one from "Harvard Women's Health" is packed with sunscreen ads. What would you expect them to say! Follow the money.

2. This one quotes a derm famous for bashing UV light. Scroll down - you forgot to read the counterpoint:

Quote:
If you do put sunscreen on as directed, you will in fact block your bodies ability to make vitamin D. Check out pg 162 of the book by Dr. Holick, The UV Advantage, "Sunscreens almost completely prevent the body from making any vitamin D from the sun. SPF 8 reduces vitamin D production by 97.5%, and SPF15 reduces vitamin D production by 99.5%." Also, it is difficult to get enough vitamin D from diet alone.
3. This one has even MORE sunscreen ads than the first one! Pure bunk - payola from big pharma keeps these kind of sites publishing fake science. They fool the public every day... including YOU unfortunately.
