Dr. Berg Maximum Strength 7-in-1 Vitamin D3 K2 5000 IU | Naturally Derived D3 | 4X Lab-Tested & Verified | High Absorption Formula | K2 D3 Vitamin Supplement - 60 Capsules

This is one of the most well-rounded D3/K2 supplements I’ve found. The 10,000 IU of D3 combined with 100 mcg of MK7 K2 gives you a solid, clinically relevant dose—not just a sprinkle. What really sets this one apart is the inclusion of purified bile salts, magnesium, and zinc, which help with absorption and overall effectiveness.Capsules are easy to take, no weird taste or aftereffects, and it fits well into a morning supplement stack. I’ve noticed more stable energy and better mood, especially in the winter months. With Dr. Berg’s reputation and ingredient quality, it feels like a smarter long-term option than basic D3 alone.

Excellent supplement for those looking to increase their vitamin D3 levels.After using only two bottles of the 10,000 IU dosage, my blood test results showed an increase from 20 ng/mL to 80 ng/mL.However, I recommend having your vitamin D levels monitored by a healthcare professional, as 10,000 IU may not be suitable for continuous, year-round use.Additionally, I noticed an improvement in libido.

Excellent product. Fast Shipping. My third order. Can tell a difference when I don't take it for a few days. I take one on most days, but if under stress I take 2 for several days in a row. No tummy upset ever. It helps my energy, and I just feel better overall. Still a bit spendy, but a better-quality blend than others I've tried. Won't be without it in future.

I bought these for my son. He reports being healthier overall, getting sick less often and recovering more quickly when he does get sick.We appreciate the blend that makes it easier for the body to absorb the Vitamin D. Excellent product.

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.

I have noticed a change in my body and it seems stone working very well for me. It is easy to swallow, and no stomach discomfort. I will be ordering again.

All-natural ingredient sources coupled with good podcasts from Dr. Berg to support your purchases and knowledge base. I also give these to my elderly mother as her D3 was a wee low. This smoothed it out and put her in the good zone according to yesterday's blood test, proving their efficacy. She's 81 with everything else at ideal levels.

Excellent product. I noticed pain in my lower back went away within a couple days. I highly recommend Dr. Bergs blend of vitamin D and K2 formula.
