Last couple of lab tests showed I was low on Vitamin D. At first I thought "yeah, whatever, I take a multivitamin every day". I'm not a believer in taking megavitamins.

But after reading some legitimate Web articles, particularly the Mayo Clinic report, I figured it might not hurt. At 56 years old, my muscles do feel weak, tired and sore, perhaps that was a symptom of the D deficiency (surely it acan't be from getting older!) So today I bought a bottle of the Wally-world "Spring Valley" brand D3 in the 5000IU strength (that's the strength the doc said to take daily). The reviews on the Walmart site were favorable. These look like liquid gel-caps.

Anybody had any success with this brand, or taking D3 supplements in general? How long before my blood levels of D3 will start to increase--how long before I might start to feel any positive results?

Thanks!
