Banana Boat SPF 100 is a good choice for sunscreen. Unfortunately, Neutrogena UltraSheer got discontinued. It was very NON-greasy and they removed just about all of the "perfumey" scent that most sunscreens have. Banana Boat has a tad more scent to it.
You might consider taking Vitamin K to improve vitamin D absorbtion. Vitamins D and K are good on their own, but even better together. Both vitamins are fat-soluble and work together to metabolise calcium in your body by activating helpful proteins.
Your body synthesizes vitamin D from sun exposure. Since you'll be staying out of the sun it makes great sense to increase your vitamin D intake from supplements and natural sources including food and if possible get some sun exposure (to areas not know to develope DSAP). Vitamin D deficiency can lead to high blood pressure, increased risk of heart attack and stroke, etc.
For healthy people who get some sunshine exposure, the government's dietary recommendations are 200 IUs a day up to age 50, 400 IUs to age 70, and 600 IUs over 70. Again, that's just the US government's recommendations and for healthy people who aren't hiding indoors all the time or at least wearing sunscreen all the time. Many experts believe that these recommendations are too low. They recommend 2,000 IUs per day during the Winter time. That tells you that as someone with DSAP who is avoiding the sun, you need much more than the government's low recommendations. And to get 2,000 IU per day you cannot get enough vitamin D through food alone! You need to either take supplements or get some sun exposure (perhaps on your back, which as far as I know is an area of the body that does not get DSAP spots). It is beyond the scope of this website to determine how much sun exposure to get. Speak to your doctor. Also here's a few links: story , story , more to come.
The biggest natural sources are milk and orange juice that specifically has vitamin D added. Minute Maid has as much vitamin D as milk.
If you are not meeting your daily vitamin D recommendation then it might make sense to chew on some Caltrate vitamins in order to ward off heart problems as well as osteoporosis. This product contains calcium with advanced levels of vitamin D to help optimize calcium absorption. Each tablet also contains five fortifying minerals important for healthy bone formation.
These chewable vitamins can sometimes be found at your local grocery store or you can just order them from Amazon. They're almost like candy so if you keep a bottle some place such as by your computer you're very likely to continue this dietary supplement regimen. I like to break them in half and then eat about 4 halves a day at different intervals.
How much can you consume? The Institute of Medicine research suggests that adults can eat up to 4,000 IU of vitamin D per day -- or 5 times that of one of these vitamins. This website says that more than 2,500 mg of calcium per day is too much -- that's about 4 of these chewable wafers, not counting daily intake from other sources. This particular product contains 600 MG of calcium plus 800 IU of vitamin D.
As a word of caution, calcium supplements are said to be linked to kidney stones. I actually got a kidney stone! Statistically only about 12 out of 100 males and and 7 out of 100 females will get a kidney stone in their lifetime. If you have had a kidney stone before and insist on taking supplements then they should be taken at meal time.
Also take a vitamin K supplement. Vitamin D and vitamin K work as a team. Some research suggests that vitamin D may be harmful without vitamin K to offset its effects, but more research is needed in this area.
Try Now Foods Apricot Kernel Oil (as a DSAP moisturizer). 4.6 ounces for as low as $2.68 is a bargain! Pure and natural with no traces of solvents. If you're one of the few patients who experience DSAP itching I don't know that this will help. Probably not. I am recommending it simply because it is cheap and it moisturizes. That's it. This product is also available at Amazon.com
