WOW!!!! I Feel So Much Better!

Here's the deal: I am VERY overweight, and I am constantly in pain. My knees and lower back are the things that hurt the most. I live on Motrin and switch it up with Aleve often. My friend gave me her bottle of Dr. Berg's Liquid Vitamin D3 with K2, Zinc & MCT Oil because she did not care much for the taste of it. I tried it that morning when I was at work and in horrible pain. I started to feel MUCH better by the end of that day. I am completely amazed by this stuff! I actually liked the taste of it. I also put it under my tongue for a minute before swallowing it. It helps your body absorb it more quickly. I can not tell you how happy I am with this. My energy levels are better, and my pain has lowered dramatically. I wanted to buy the pill form but noticed the ingredients are a little different. I am not about to ruin a good thing, so I will stick with the oil form!

Is serving size accurate?

I purchased on 8/25 and Iโ€™m already in need of a new bottle. Iโ€™m wondering if it really contains 38 servings as stated. I am taking it daily and so is my son whoโ€™s 9 years old. Iโ€™m giving him 1 dropper full and Iโ€™ve been taking 2 dropper fulls daily. Today is 9/2 and my bottle is almost empty. Iโ€™ve only had it a week. I love the product and would like to continue purchasing but I donโ€™t want to buy a new bottle weekly.

Had to return

Unfortunately I had to return because of the stevia. It's my fault for skipping over that fact. I was adding stevia to my daily drink a couple years back and it and my menstruation was impacted. I came to learn I am not the only one who experienced that. Now I avoid stevia and pretty much any sugar alternative for my kids and I.

Gave me nausea that I couldnโ€™t shake for at least six hours

I went ahead and took a chance on this stuff because I read somewhere that vitamin D three deficiency could lead to hair loss yada yada yada so I figured I would go ahead and try it. I took it yesterday and midway through the day I started having this unshakable nausea that just would not let up. Iโ€™m pretty sure it was the supplement seeing as how itโ€™s the only thing that I introduce new to my diet yesterday. I would wave prepared for side effects from this product

Dr. Berg's Supplement line offers Old School, natural, High quality health Products

This product is loaded with all of the things that will help your Vitamin D absorb into your body well. In some cases, vitamins need other ingredients to make the nutrients absorb into your body. When you take the vitamin or mineral on their own without getting it from the food, it often has other agents that are missing that are usually in place that help the nutrients absorb into the body well. This has vitamin K and Zinc to help out with absorption, as well as MCT oil. MCT oil is highly beneficial so you can bet that this product will boost your immune system and give you the health benefits you need, right away!
