Dr. Berg Maximum Strength 7-in-1 Vitamin D3 K2 10,000 IU | Naturally Derived D3 | 4X Lab-Tested & Verified | High Absorption Formula | K2 D3 Vitamin Supplement | 120 Capsules

I've recently started taking Vitamin D3 K2, and the benefits have been outstanding! This powerful combination has significantly boosted my immune system, helping me feel more resilient during cold and flu season. Vitamin D3 supports my bone health and mood, while K2 works synergistically to ensure proper calcium utilization in my body, contributing to stronger bones and cardiovascular health. I've noticed an improvement in my energy levels and overall vitality, making it easier to stay active and engaged throughout the day. This supplement has truly enhanced my wellness routine, promoting not just physical health but also a sense of well-being that I didn't realize I was missing. I highly recommend Vitamin D3 K2 to anyone looking to support their health naturally!

Everyone in the planet should be taking this stuff! Vitamin D is so essential for good health, and this brand is the best D3K2 I have found. The ox bile makes it so you can take it without food, it is inexpensive and it works. My vitamin D level went from 30 to 200! I noticed improved sleep after just a week, my BP has gone back to normal, I have energy all day, I haven't been sick in a year and I'm a nurse who is around sick people all day. If you only take 1 supplement, this should be it

I’ve been taking the Dr. Berg Maximum Strength 2-in-1 Vitamin D3 K2 supplement, and overall I think it’s a solid product—especially if you’re specifically targeting vitamin D support along with bone and cardiovascular health. It provides a high dose of Vitamin D3 (10,000 IU) combined with Vitamin K2, which is important because K2 helps direct calcium to the bones rather than allowing it to build up in arteries. That combination is the main reason I chose this type of supplement instead of taking D3 alone. I do think it’s important to be careful with a high-dose product like this. Before starting, I had my vitamin D levels checked through blood work, and I would strongly recommend anyone else do the same. Vitamin D is one of those nutrients where more is not always better, and long-term overuse can lead to excessive levels if you’re not monitoring intake. In my case, I’m using it as part of a broader health routine focused on bone support and overall vitamin optimization, and it seems to fit well. Overall, this is a strong, high-potency supplement with a good D3 + K2 combination, but it should be used responsibly with attention to blood levels to avoid over-supplementation.

Amazing med, I have a low D problem so it’s a must have for me. I didn’t realize how important the K part works until I listened to Dr Berg on Facebook. I do notice a little less joint pain. Over Christmas I had a friend visiting, he’s a big guy post stomach staple surgery. He was acting like a jerk, very irritable and anxious. I’m a nurse so I started him on these pills and gave him a bottle to take home. When he followed up with his doctor he indeed have a very low vitamin D issue. His doctor gave him a script until his levels are better but want him to continue on these after. He is up to normal.

Love this product. Good absorption. Not hard to swallow like other pills can be

Its a good product. But be careful. Chk your blood vit D level. Mine ckd a week ago was 140. Way too high bordering on dangerous. I have one kidney and low hematocrit. That can cause D3 to be raised by the body not the dosage of this supplement. Pls make sure you insist your Dr orders D3 and CMP. Very important. You most likely have to ASK your Dr to order this (sadly) !!

My doctor recommended this specific brand for my Vitamin D efficiency. She said it’s a quality product and well-tested. A couple of months after starting it my blood was retested and my vitamin D levels are now perfect!

We like the education Dr Berg brings us through his YouTube videos. This product helps me meet my requirement for intaking 40K IU per day. I have a high trust level in his products, serving to keep me healthy.

I like this combined vitamin very much. First, 10.000 IU vit D3 per capsule (I never take a capsule but drop the powder in water and drink) and then the additional K2 you need as well. I take it now every day and feel the difference already.

These are quite good I feel some difference after a few days. But it seems date of expiry was temped.

Great

must try

my 1st purchase was on January 2025 and I feel significant healthier than before regarding my knee pain and overall ...I used to get this "insufficient level" result of Vit D before I consumed this. Then after 4 months consuming Dr.Berg Vit D3 10000iu +K2 , I had my Vit D level checked again and the result showed "sufficient level" on May 2025. I'm happy that this supplement actually works. For maintenance I consume 5000iu now.
