What You'll Feel
Ingredients
A simple, intentionally formulated blend of high-quality Vitamin D3 (as cholecalciferol), Vitamin K2 (as menaquinone-7, MK-7) and Organic Coconut Oil. Sofgel (gelatin, glycerin, purified water).
Third-Party Tested
Every batch is lab tested independently for purity, potency, and heavy metals through a ISO 17025 Accredited Lab. All of our products are manufactured in FDA-registered, cGMP-certified facilities.
How to use
Start with 2 softgels daily, in the morning, to correct deficiency, then transition to 1 softgel daily for long-term maintenance. Short-term higher-dose use is intended for repletion only. Routine vitamin D lab testing is recommended to monitor your levels and find your ideal dose.
Each pouch contains 300 softgels, giving you up to a 10-month supply. Take it consistently; vitamin D builds up over time, so you won't feel the full effects immediately.
Most people notice improvements in energy and mood within 2-4 weeks.
Formula Details
Not all Vitamin D3 + K2 is sourced the same. Our D3 is Swiss-sourced cholecalciferol, a well-studied form of Vitamin D3 naturally derived from lanolin. We pair it with Vitamin K2 as menaquinone-7 (MK-7), sourced from Poland. Then we manufacture and third-party test the finished formula right here in the USA for quality and purity from start to finish.

Let customers speak for us
I think this is a great company. My sister has been using them for awhile and was the one who recommended them to me.
Love these, got my gf a bag too
They send lovely emails about how much your purchase means to them. They also update you on the progress of your order. Delivery did not take long as it ships from the US.
This is my favorite vitamin D. It has K2, so i don’t have to bother about pairing it with anything.It is also made with organic coconut oil!!!! It is made in the US too!! I no longer feel lethargic at work since i started taking it. 300 soft gels and you get good deals often. I have also bought for my parents.
Smart presentation and as far as I know effective…
I have been taking D3 for years, but this formulation has purified results I can really feel. Reasonable shipping time.
Super impressed with this Magnesium Glycinate! I started taking it in the evenings to help with stress and nighttime leg cramps, and the results have been fantastic. I wake up feeling refreshed without any morning grogginess, and it doesn't cause any digestive upset like other forms of magnesium do. Will definitely keep buying from Real Good Essentials!
So far I happy with this product
Works well easy to take!
I have bought eight packs so far for myself and family. vitamin D is in the cell. There's no testing that measures it in the cell. Standard medical tests only measure circulating vitamin D, which mine is normal. I have had better quality sleep since taking these, but you also have to take co factors like magnesium for that to work. I take two different types of mg, glycinate and L Threonate.
This is a great company & product!! Very easy to place my order and it was delivered in a timely manner.
Very satisfied with my D3+K2 (MK7) Coconut Oil Softgels..Three major healthy vitamins in one ! I'm on my second order of two bags of 300 softgels (per bag). So far, so good ! A real healthy deal for the money, and delivery didn't take a month.
They have helped me no more sulfur burps and i feel better
I been taking this great vitamin D3 with K2 for over a month now is made a difference with energy i have it in my Stack now 🙏
Very good, doing what promised!!!!

Frequently Asked Questions
Where is this sourced/made?
Our Vitamin D3 is sourced from pharmaceutical grade lanolin in Switzerland under strict European Guidelines and our K2 as (Menaquinone-7) is sourced from Poland. We proudly manufacture right here in the USA 🇺🇸 in a certified FDA registered/cGMP facility.
Isn't 10,000 IUs a lot?
Each softgel is 5,000 IUS which is the perfect maintenance dose, the suggested use of 10,000 IUs is 2 softgels and helps correct deficiencies.
This may sounds high, but most people are severely deficient without knowing it. The Endocrine Society recommends 1,500-2,000 IU daily just for maintenance — but if you're deficient, you need much more to restore optimal levels. 10,000 IU is considered safe for most adults and is what many doctors prescribe for deficiency.
Plus, our formula includes K2 which helps your body use vitamin D more efficiently and safely.
Are these lab tested?
Yes, every batch is lab tested for purity, potency, and heavy metals. We also test for microorganisms and contaminants. All of our products are manufactured in FDA-registered, GMP-certified facilities.
How much & how often should I take this?
Start with 2 softgels daily, in the morning, to correct deficiency, then transition to 1 softgel daily for long-term maintenance. Short-term higher-dose use is intended for repletion only. Routine vitamin D lab testing is recommended to monitor your levels and find your ideal dose.
Each pouch contains 300 softgels, giving you up to a 10-month supply. Take it consistently; vitamin D builds up over time, so you won't feel the full effects immediately.
Most people notice improvements in energy and mood within 2-4 weeks.
Why do I need K2 with D3?
Think of D3 as the key that unlocks calcium absorption, and K2 as the GPS that tells calcium where to go. Without K2, calcium can end up in your arteries instead of your bones — which is dangerous. K2 ensures calcium goes into bones and teeth where it belongs, not soft tissues where it causes problems.
How is this different from store-bought D3?
Three major differences: (1) Clinical dosage of 10,000 IU vs. the weak 1,000 IU in most brands, (2) Includes K2 for proper calcium utilization, and (3) Uses coconut oil for superior absorption instead of cheap soybean oil fillers. Most drugstore vitamins are made to hit a price point, not deliver results.
Will this interact with my medications?
Vitamin D3 is generally safe with most medications, but high doses can affect blood thinners like warfarin. If you take prescription medications — especially blood thinners, thiazide diuretics, or steroids — consult your doctor before starting. Always better to check than guess.
How long before I see results?
Most people notice improved energy and mood within 2-4 weeks of consistent use. Joint comfort improvements typically take 6-8 weeks. For full benefits, plan on 3 months of daily use — that's how long it takes to optimize your vitamin D blood levels. Remember, you didn't become deficient overnight, so restoration takes time too.
Real Customers. Real Relief.
Doctor is pleased
Capsules are much smaller than regular capsules and super easy to swallow. My doctor is pleased that I’m taking this supplement because my labs showed I was deficient in Vitamin D. After 3 months, my labs showed much better. Just placed my second order.
A happy repeated customer
Of course I was apprehensive initially, hoping D3 with K2 would be an improvement over D3 alone. After reading in on the combo and the inclusion of coconut oil, I purchased my first bag. It didn’t take too long to achieve a more energetic start to my day after starting this vitamin. In conclusion, I’m a happy repeat customer.
Love the tiny little ‘bombs’ of Vitamin D
Love the tiny little ‘bombs’ of Vitamin D. So easy to swallow, no belly upset, no aftertaste. Customer service is amazing. I’m hooked, converted my husband too!
Excited about new beginnings
Well, I have to say since I’ve been taking this products i feel more energized and focus. Truly only started this product 2.5 weeks ago due to other issues. I have a health condition that just drained me . I had no desire to get out of the house. But I’m very happy to say I do have energy enough to start moving. It’s been a long road for me and I’m excited about this new beginnings
Very happy so far
I have bought eight packs so far for myself and family. I have had more energy and better quality sleep since taking these with co factors like their magnesium glycinate.
Absolutely should be taking D3K2
My doctor said I absolutely should be taking D3 + K2. I researched thoroughly which product to order and chose this one. I feel like I have more energy which makes me very happy. Im a senior citizen but live on a farm with lots of chores. The heat has really zapped my energy but I feel better now than before I began taking.
