I think I remember reading somewhere that low Vitamin D can weaken teeth. I know a lot of people with CFS have low levels, myself included.

I have low vitamin D. I have often been put on prescription doses. So, I started taking a supplement. My teeth are good, thank God. But, yeah, vitamin D seems like a good idea, especially if you have tested low. Love you all.

My Vit D is very low even though I've been on crazy high prescription supplements for 3 yrs now.

My teeth are breaking like crazy. Seems a piece falls off a tooth weekly. My nails are in very bad shape also and when I'm in a crash my hair falls out. Can't go in the kitchen without a hair net anymore.

There's an article on vitamin D at Mercola.com that seems pertinent here. In the article it states that supplementation isn't the best way to boost vitamin D...sunlight is. We've been so indoctrinated to avoid the sun these days, but studies have repeatedly shown that the deadly form of skin cancer is much more prevalent among office workers than in people who work outside all day.

Explain that one to me. Could the doctors be wrong about some things? I've heard that the way to avoid melanoma is to stop putting all these strange chemicals into our bodies, not avoid the sun. The sun can cause other types of skin cancer, but those aren't lethal...only melanoma is.

I don't believe everything I read online, but I have changed my views on sun exposure. I give myself as much as my body seems able to tolerate well. I think the many benefits outweigh the possible harm. We as humans did not evolve inside of houses and apartments...our bodies are built for the environment out there...you know, that place that has no ceilings and walls?...that alien land you hurry through to get from your house to your car?

Thank you for mentioning that exposure to the sun is the best way for your body to manufacture Vit. D and melatonin as well. Maybe that will help those of us who are not getting good sleep.

Wow, I know what you mean about your hair falling out. I clog the vacuum all the time with my huge hair balls. I'm lucky to have a lot of hair, so the loss is less noticeable. I take Biotin and I think I am losing less since beginning to take that. Smiles.

Xylitol helps with dry mouth. Toothpaste, mouthwash, gum.... Not sure what other forms there are, maybe treated floss? I like a little bit in tea. I get dry mouth from medication....

Hair falling out...that's another symptom of ME/CFS that's really annoying sometimes. I've had to wash my hair in a laundry tub that drains out onto the ground because washing it in the shower keeps clogging the drain.

I wake up and have hair that fell out onto my pillow stuck to my face. I lean over the sink to brush my teeth and my hair falls into the sink. It clogs the shower, the washer, and get's entwined in my clothes.

I too have thick hair so someone wouldn't notice my hair loss, but the loss of eyelashes, arm hair is getting noticeable.

OK, well skinnybinny just explained why my eyelashes are thining. And Richie, I get what you are saying. Every time I take a bath, I have to pull a squirrel out of the drain. Yuck!

I love the book "The Vitamin D Solution"... a very interesting read, with lots of research to back it up. Getting my levels up has helped with my muscle pain and I also think it helps to fight colds.
