If you’re searching for a supplement to boost your energy, strengthen your bones, and support your overall health, Dr. Berg’s Vitamin D3 and K2 is worth your attention.
I’ve been using it for months, and the results have been impressive—more energy, better mood, and a sense of vitality I didn’t expect.
This powerful combo of vitamins, packed with premium ingredients, could be the game-changer you need.
Let me share my journey, break down the pros and cons, compare it to other brands, and give you practical tips to get the most out of it.
My Experience With Dr. Berg Vitamin D3 And K2
I started taking Dr. Berg’s Vitamin D3 and K2 about six months ago, prompted by a nagging sense of fatigue and a blood test showing my vitamin D levels were embarrassingly low. Living in a cloudy city, I knew sunlight wasn’t doing me any favors, so I decided to give this supplement a try after watching Dr. Berg’s YouTube videos.
His explanations about how vitamin D3 works with K2 to direct calcium to the right places—like your bones instead of your arteries—made sense to me, and I was curious to see if it would deliver.
The first thing I noticed was how easy the capsules were to swallow. I went with the 10,000 IU capsules, which also contain 100 mcg of K2, plus extras like MCT oil, zinc, and magnesium for better absorption. Within a couple of weeks, I felt a subtle shift—less sluggishness in the mornings and a bit more pep during my workday. By month two, my joint aches, which had been creeping up as I hit my late 40s, started to fade.
I even noticed my mood lifting, especially during the dreary winter months when I usually feel down. Was it a placebo effect? Maybe at first, but my follow-up blood test showed my vitamin D levels had climbed to a healthy range, which was proof enough for me.
What I love most is the convenience. One capsule a day with my breakfast, and I’m set. No weird aftertaste, no upset stomach—though I’ll admit, I was skeptical about the ox bile in the formula at first. Turns out, it’s there to help your body absorb the fat-soluble vitamins better, and it didn’t cause me any issues.
I’ve also tried the liquid version for a change, which has a pleasant vanilla-mint flavor, making it a great option if pills aren’t your thing. My only gripe? The price felt steep initially, but the results have made it worth every penny. This supplement has become a staple in my routine, and I’m excited to share why it might work for you too.

Pros Of Dr. Berg Vitamin D3 And K2
- High Potency Formula: The 10,000 IU of D3 paired with 100 mcg of K2 is a powerhouse combination, delivering a robust dose that tackles deficiencies effectively. I noticed a significant energy boost within weeks, which is a testament to its strength.
- Enhanced Absorption: The inclusion of MCT oil and ox bile makes a real difference in how your body takes in these fat-soluble vitamins. I’ve tried other brands without these extras, and my blood tests never showed the same improvement.
- Comprehensive Health Benefits: This isn’t just about bones—it supports your immune system, mood, and even heart health by ensuring calcium goes where it’s needed. My mood swings have stabilized, and I haven’t caught a cold in months.
- Quality Manufacturing: Made in cGMP-certified facilities in the USA, the supplement feels trustworthy. Knowing it’s been lab-tested four times gives me confidence I’m not swallowing junk.
- Convenient Dosage: One capsule a day is all it takes, fitting seamlessly into my busy mornings. The liquid drops are even easier if you prefer a quick squirt under your tongue.
- No Weird Additives: The ingredients are clean, with no unnecessary fillers that I’ve seen in cheaper brands. The vegetable capsule and natural flavor in the liquid version make it feel premium.
- 30-Day Money-Back Guarantee: If it doesn’t work for you, you can get a refund within 30 days. I didn’t need it, but it’s nice to know there’s a safety net.
The combination of high potency and thoughtful formulation makes this supplement stand out. I’ve felt the difference in my energy, joint comfort, and overall well-being, which is why I keep coming back to it. Plus, the peace of mind from knowing it’s made with strict quality standards is a big win.
Cons Of Dr. Berg Vitamin D3 And K2
- Premium Price Point: Let’s be honest—this supplement isn’t cheap. At around $40 for a 120-capsule bottle, it’s a bigger investment than some generic brands, which can sting if you’re on a tight budget.
- Potential Side Effects: While I didn’t experience this, some users report nausea or stomach upset, possibly from the ox bile. If you have a sensitive stomach, you might need to start with a lower dose.
- High Dosage Concerns: The 10,000 IU of D3 is great for deficiencies, but it could be too much for some people. I had to check with my doctor to make sure it was safe for me long-term.
- Not Ideal For Everyone: Pregnant women, kids under 18, or those with certain medical conditions should consult a doctor first. I wish the label made this clearer for new users.
- Limited Availability: I’ve noticed it’s sometimes out of stock on Amazon, which can be frustrating if you rely on quick shipping. Planning ahead is a must.
- Taste Of Liquid Version: While I like the vanilla-mint flavor, some users find it too sweet or notice crystallization in the bottle, which can feel off-putting.
These drawbacks don’t outweigh the benefits for me, but they’re worth considering. If you’re sensitive to supplements or watching your wallet, you might need to weigh these factors carefully.
Maintenance Tips For Dr. Berg Vitamin D3 And K2
- Take With A Fatty Meal: Since D3 and K2 are fat-soluble, I always pop my capsule with breakfast that includes avocado or eggs. This boosts absorption, and I’ve noticed better results when I’m consistent.
- Monitor Your Vitamin D Levels: I get my blood tested every six months to ensure I’m not overdoing it. Too much D3 can lead to issues, so checking in with your doctor keeps you safe.
- Store Properly: Keep the bottle in a cool, dry place with the lid tight. I learned the hard way that leaving it in a humid bathroom can degrade the capsules.
- Start With A Lower Dose: If you’re new to high-potency supplements, try the 5,000 IU version first. I started here before moving to 10,000 IU, and it helped my body adjust.
- Combine With A Balanced Diet: I pair this with K2-rich foods like natto or cheese to enhance its effects. It’s not a magic pill—your diet still matters.
- Watch For Side Effects: If you feel nauseous or off, cut back and talk to your doctor. I had a friend who needed to tweak her dose to avoid stomach issues.
- Use The Liquid For Flexibility: The liquid drops let you adjust the dose easily. I sometimes use half a dropper if I’m eating vitamin D-rich foods that day.
Following these tips has made a big difference in how well the supplement works for me. Consistency and a little planning go a long way in getting the most out of it.
Comparison With Other Brands
Bronson Vitamin D3 And K2
Bronson’s version offers a solid 5,000 IU of D3 with 90 mcg of K2, which is decent but less potent than Dr. Berg’s 10,000 IU option. I tried it for a month, and while it worked, I didn’t feel the same energy boost. It lacks the MCT oil and ox bile, so absorption might not be as efficient. It’s cheaper, though, which is a plus if you’re budget-conscious.
Thorne Research D3 And K2
Thorne’s supplement is a favorite among health nuts, with 5,000 IU of D3 and 100 mcg of K2. It’s high-quality and made in the USA, but it doesn’t include the extra nutrients like zinc or magnesium that Dr. Berg’s has. I found it effective, but the lack of absorption enhancers made me stick with Dr. Berg.
Nature Made Vitamin D3 And K2
Nature Made is a household name, offering a budget-friendly 2,500 IU of D3 with 100 mcg of K2. It’s great for beginners, but I barely noticed a difference when I used it. The lower potency and lack of additional ingredients make it less comprehensive than Dr. Berg’s formula.
Garden Of Life Vitamin Code D3 And K2
Garden of Life’s raw, whole-food-based supplement has 5,000 IU of D3 and 100 mcg of K2, plus probiotics. I liked the natural vibe, but the capsules are larger and harder to swallow. It’s pricier than Dr. Berg’s, and I didn’t feel the same mood lift.
Each brand has its strengths, but Dr. Berg’s stands out for its potency, absorption aids, and extra nutrients. If you want a middle ground, Thorne or Bronson are solid, but for maximum impact, I keep going back to Dr. Berg.

Frequently Asked Questions (FAQ)
Picking the best brand depends on your needs, but I’m partial to Dr. Berg’s Vitamin D3 and K2 for its high potency (10,000 IU D3, 100 mcg K2) and absorption-enhancing ingredients like MCT oil and ox bile. It’s made in cGMP-certified facilities, which adds trust. Thorne and Bronson are close contenders for quality, but Dr. Berg’s extra nutrients and noticeable results—like my improved energy and joint comfort—make it my top choice. Always check with your doctor to find what suits you best.
If you’re pregnant, nursing, under 18, or have conditions like hypercalcemia or kidney issues, you should talk to your doctor before taking D3 and K2. I’ve read about people with sensitive stomachs experiencing nausea from high doses, possibly due to ingredients like ox bile. Those on blood thinners should also be cautious, as K2 affects clotting. I had no issues, but checking with a healthcare provider ensures it’s safe for you.
From my experience, yes, it works. After months of taking Dr. Berg’s D3 and K2, my vitamin D levels went from low to optimal, my joint pain eased, and my mood got a noticeable lift. The science backs it up—D3 boosts calcium absorption, while K2 directs it to bones and teeth, not arteries. User reviews echo this, with many reporting better energy and health, though some note side effects like nausea. Results vary, but for me, it’s been a game-changer.
Dr. Berg’s capsules come in 5,000 IU or 10,000 IU of D3 with 50 mcg or 100 mcg of K2, respectively. I take one 10,000 IU capsule daily, as recommended for deficiencies, but the ideal dose depends on your levels. Dr. Berg suggests a 1000:10 ratio (10,000 IU D3 to 100 mcg K2) for balance. My doctor approved this, but you should test your blood levels and consult a professional, especially if you’re new to high doses.
Conclusion: For Dr. Berg Vitamin D3 And K2
Dr. Berg’s Vitamin D3 and K2 has transformed my daily health, and I believe it can do the same for you. Its potent formula, quality manufacturing, and real results—like my boosted energy and reduced joint pain—make it a standout. Despite the higher price, the benefits outweigh the cost. If you’re ready to feel more vibrant and support your bones, mood, and immunity, grab a bottle and see the difference for yourself.
