"This is my second time repurchasing this. I’ve taken Vitamin D supplements before, live in California, and get plenty of sunshine. However, I’m always fatigued, especially around the time of my menstruation. I notice the effects right away when taking this form of Vitamin D! In all of the positive ways - I’m less fatigued, in fact I have crazy amount of energy, I’m not depressed as usual, and my mental clarity has heightened. Even though it comes with a few in the package, I’d rather take this every week than most vitamin D supplements that I take every day and having zero effects."

"These are perfect for long dark winters. Here in Kentucky, it seems like it is always wet and muddy over the winter leaving no chance for me to go outside and walk. These work out perfectly to keep everyone healthy despite not being able to go out in the sunshine for months."

"I was looking for a Vitamin D that I'd only need to take once a week, and this seems perfect for that. This has a tracker on the foil packaging which reminds me if I took one the week prior or not. It's labeled as week 1, 2, 3, 4 - so I'll never get mixed up. A friend takes this and told me it will help keep my immune system in check and help me feel less tired. Can't wait to see how I feel after taking it for a few weeks. The price is great so if I do well with it I will definitely get the 12 week pack."
