Vitamin D is instrumental in several bodily functions. One of the values is that can improve the mental status and promote an elevated mental status!

I started these over a year ago to supplement because I had a tendency to have low D levels when my blood work was tested yearly. For the first time I didn't have to be prescribed a vit D prescription, so I do feel like these keep me at a healthier level.

I had a D3 deficiency a few years back. Started this 5000 IU and 6 months later was tested again and my level was up to mid range.,...I can't remember the exact levels as it's been 3 years or more. I DO remember it didn't raise it so high it was extremely elevated but just where we wanted it to be. Whatever else is in it, soy etc. is not something I'm bothering with at this moment. I'm not up to date on soy. Not allergic but Lord only knows what they will prove next.

Taking for Vit D deficiency. I take it daily. I feel much better. My family noticed big difference in my energy, movement. I was very sluggish before. A TIP for those with hair growth issues. When I started taking 10000 a day and boy did my hair start growing. I had hair where I had not in 5 years. This was a happy surprise. If you are deficient it will take its toll energy, hair, mood etc. People are inside most of the day and do not get enough sun Vit D. Dr. said most people have some deficiency from being in side so much. Just my experience, hope this helps someone.

I have been using Members Mark vitamin D-3 5,000 IU for many years now. I rarely get sick and if I do I am never sick as long or as bad as everyone else. I am allergic to the sun so this is the only way that I can get the main D-3 that I need. I used to always get very sick any time there was a bug that was going around and I would have a very hard time getting over it. I almost always had to go on antibiotics. I am very thankful for this vitamin! You can't beat the price for the quality and quantity either!

Great price. Makes it affordable for the whole family to take.

I believe that the product is doing it's job. Very satisfied

My husband needs to take this vitamin per doctors orders and his blood work showed the vitamin was doing what its suppose to. Good price from Sams with a huge quantity!

I've been taking these D3 tabs every day since the beginning of August 2015 and I feel an over all improvement with my well being. Blood work shows excellent progress as well.

I am happy to find a reasonable source for vit d 5000 mg
