Last week, I suggested you take D3 to help ward off the flu. Well, if you followed my advice (and I hope you did), here's another thing D3 will do for you. It just might lower your insulin resistance, if you're prediabetic.

Scientists recruited 81 South Asian women with insulin resistance to take part in a study involving the sunshine vitamin. Half the women got 4,000 IUs of D3 for six months. And the other half got a placebo. At the end of six months, the D3 women significantly lowered their insulin resistance following meals. They also lowered their fasting insulin levels.

So if you followed my advice last week and started taking 5,000 IUs of D3, good for you. Keep it up. If you haven't started yet, there's no time like the present. Especially since you'll get two times the protection for the price of one!
