Really helped me
This is by far the best supplement I’ve ever tried! After taking Dr. Berg’s D3 & K2, I noticed a big difference in my overall energy and well-being. My mood improved, my bones and joints feel stronger, and I just feel healthier every day. The capsules are small and easy to swallow, and I haven’t experienced any side effects. Highly recommend this product to anyone looking to support their immune system and bone health. Thank you, Dr. Berg, for such an amazing and effective supplement!”

My Energy’s Up, My Joints Don’t Hurt, and I Haven’t Been Sick
Dr Berg’s products have become a staple in my household. Within days, I noticed a difference in my energy levels. These vitamins are easy on the stomach-No weird aftertaste, no nausea, and it’s a small capsule, which makes it wasy to swallow. I also noticed my skin was getting clearer, my nails getting stronger, and less joint stiffness so there is a real benefit there. It’s also free from any sketcy ingredients. If you’re looking for a high-quality D3 supplement that actually delivers, this is the one.

They are from a quality good source according to this Dr. you get what you pay for.
I’ve taken these over a year. They are a quality good source. You have to take K2 with D3 or the D3 can’t be absorbed in your body. It’s help my immune system greatly!! My husband takes it now too & he hasn’t been sick in a while (outside of some allergies). No taste really. Easy to swallow. The color is neutral. Organic earth. I feel good when I’m protecting my body /immune system. I take 1 a day (so does my husband). He takes his at night & I take mine in the morning. I honestly haven’t noticed a huge spike in my energy but I know I’ve felt better. The dosage is what’s required is my understanding.

Great Vit D Supplement to Replace RX Version
I have been taking this product for over a year. I was Vit D insufficient on a blood trst, so my doc prescribed a once a week RX of Vit D (big dose at once). However, it made my stomach hurt so I triesd this daily Vit D. No stomach pain! It did take a week or 2 of taking it daily to feel better and have more energy, but that’s OK- most supplements are not instant. My last bloodwork showed I was right where I needed to be for healthy levels of Vit D, so the quality level is good. I’m still taking it. It’s not a huge capsule, which is nice too, making it easy to swallow.

Good starting point…
Good product. Reordered. I only wish he would sell a gel version D3, in a pure oil like MCT or olive oil. I understand he is not putting in magnesium because people like to take their preffered versions, and at different times of the day. I saw someone else complain about this, and that is basic marketing ignorance.I have low vitamin D at 29ml. **I have not retested yet. Once I got through the pain of the initial cell receptor site reloading (yes, reloading vitamin D can cause pain after years of deficiency), this D supplement is slowly removing all my bone pains and TMJ. Half way through my first bottle, I decided to switch to some gel capsules by “micro ingredients”. After a few days I strongly felt they were NOT working. I went back to the dr berg d3 and got my healing back on track.I take two 5,000 iu Dr Bergs, and added in 20,000 iu NOW gel capsules additionally each day.Total, 30,000 ius D3, 300 mcg k2, magnesium 400-600 mg. Sometimes selenium. ** I am following Dr Coimbra protocol roughly.**note, dr berg adds zinc in this supplement and b6, so need to take in other supplements.Again, I just prefer gel pills. But these dr berg pills are reliable, and the zinc and b6 and bile salts are nice failsafe touches from a person who truly loves research and holistic healing. I would highly recommend for vitamin D3 newbies.

Great Vitamin for price
This is an awesome product and definitely helps with low vitamin D deficiency. I have been taking this for over a year now and it has absolutely raised my levels and for the price, you can’t beat it.
