I created this for myself because even though I live on the West Coast and it's sunny all the time, my vitamin D levels were always sub-optimal. When I did take vitamin D supplements, I had to take a very high dose to improve my blood levels. That's when I discovered most forms of Vitamin D (in oil form) do NOT get absorbed properly. They are cheaply mass-produced.
I noticed many of my clients also had sub-optimal Vitamin D levels. I did my research and discovered that plant-based, micro-encapsulated Vitamin D3 (as Cholecalciferol) is up to 4x better absorbed than the cheap, gel caplets.
Next, I needed to also utilize a specialized form of Vitamin K2 (MenaQ7® - Natural MK-7; as trans menaquinone-7) with D3 for better absorption and calcium utilization.
Perfect Vitamin D3+K2 is the ONLY doctor-formulated version containing these 2 specific forms of D3 + K2 at the correct clinically validated dosages.
It's a silent epidemic and it gets worse with age. Yes, most of us don't get enough sunlight, especially if you work indoors, live in a northern climate, or use sunscreen. Darker skin tones also absorb less Vitamin D from sunlight, so they need double the sunlight. Being overweight, having unbalanced cholesterol levels, and poor hormone levels all reduce vitamin D absorption and production.
But here's what most people don't know: as we age, our skin becomes less efficient at producing Vitamin D from sun exposure, and our kidneys convert less of it into the active form the body can actually use. Dietary sources are also extremely limited — it's nearly impossible to get enough from food alone. Even in sunny climates, deficiency is extremely common after the age of 35. The result is a widespread, silent deficiency that affects immunity, bones, mood, brain function, and heart health.
Form makes all the difference — and this is where most supplements fail. For Vitamin D, most use D2 (ergocalciferol) — synthetic, poorly absorbed, and far less effective. Others use D3 from lanolin (sheep's wool grease) — an animal-derived form. I use only plant-based D3 from lichen — the cleanest, most body-ready form available, microencapsulated for superior absorption.
For Vitamin K2, the cheap version is MK-4, which clears your body in just a few hours. I use MenaQ7® — a patented, natural MK-7 form that stays active in your bloodstream for days, giving you continuous "24/7" K2 protection from just one daily capsule. Using the wrong forms is the number one reason people get no results from their Vitamin D supplement.
This is one of the most important things I can tell you. Vitamin D3 increases calcium absorption, which is great. But without K2, that calcium doesn't always go where it should. Instead of going into your bones and teeth, it can deposit in your arteries and soft tissues, which reduces blood flow.
Think of it like running a shower with no drain — the water has nowhere to go. K2 is the drain. It activates the proteins that direct calcium into your bones (where it should be) and away from your blood vessels and arteries (where you do NOT want).
Taking D3 without K2 is not just ineffective. Over time, it can actually be counterproductive. They work as a team, and that's exactly why I combined them in this formula.
Lastly, the correct ratio is needed, which is the exact clinically researched dose found in this product.
Most people notice steadier energy and a more positive mood within the first 1–2 weeks because Vitamin D directly affects brain chemistry and neurotransmitter production. Additionally, because Vitamin D is technically a hormone, it also has positive effects for muscle growth, the nervous system and libido.
Immune resilience typically improves over the first 4–8 weeks. Deeper benefits such as stronger bone density, healthier calcium metabolism, and cardiovascular support build over months of consistent daily use.
Your best benchmark is a blood test: check your 25-OH Vitamin D levels before starting and again after 90 days. Most people move from deficient or sub-optimal into the healthy "high-normal" range, which is the real goal. One bottle is a full 3-month supply — designed exactly for this evaluation window.
Take 1 capsule daily with food, preferably in the morning. The most important detail: take it with a meal containing some healthy fat — eggs, avocado, nuts, olive oil, or butter. Vitamin D3 and K2 are both fat-soluble, and taking them with dietary fat can improve absorption. If you're under extra stress, feeling under the weather, or need an immune boost, you can temporarily increase to 3–4 capsules daily, all taken at once in the morning with a fat-containing meal. This is safe for short-term use. Consistency is everything with this formula, just one capsule a day, every single day.
Lastly, if you miss a dose, simply double it the next day. Because it's fat-soluble, it has a long half-life.
Please consult your doctor before starting if you take any of the following. Critical: if you are on warfarin (Coumadin®) or any blood-thinning medication, do NOT take this product without your doctor's direct supervision. Vitamin K2 directly affects how warfarin works and can alter your INR levels — this is a serious interaction that requires medical monitoring. Also, speak with your doctor if you take corticosteroids like prednisone, weight-loss drugs like orlistat, cholesterol-lowering medications like cholestyramine, or anti-seizure medications like phenobarbital or phenytoin — these can interfere with Vitamin D absorption or metabolism. For everyone else not on prescription medications, the formula is extremely well-tolerated and safe for daily use.
Vitamin D is very well tolerated. And, doses of up to 100,000 units have been taken daily with no negative side effects. However, the biggest problem of taking Vitamin D is the potential calcium buildup in your arteries. This is why we've included Vitamin K2, utilizing the natural form of MK-7, which helps direct the calcium into the bones where it belongs.
However, if you have a history of hypercalcemia (high blood calcium), kidney stones, or a calcium metabolism disorder, consult your doctor before using any vitamin D supplement. Do not use if pregnant, nursing, or under 18 without a doctor's approval.
Yes — across the board. Perfect Vitamin D&K™ is 100% natural, Non-GMO, and one of the ONLY truly vegan D2+K2 supplements. We use a special natural form of D3, which is plant-based, sourced from lichen — not from lanolin (sheep's wool grease) like most D3 supplements. The K2 is from natural fermentation via the patented form of MenaQ7® — not synthetic. It also uses plant-derived capsules, while other companies use gelatin caplets. It also contains NO gluten, dairy, soy, eggs, fish, or peanuts — zero artificial fillers. Manufactured in the USA in an FDA-registered, GMP-certified facility, third-party lab tested for purity and potency.
Five specific things set this apart.
First, it uses the correct active forms — plant-based D3 from lichen (not cheap D2 or animal lanolin) paired with patented MenaQ7® K2 MK-7 (not short-lived MK-4).
Second, it's a complete, no-compromise formula — 5,000 IU of D3 plus 50mcg of K2 in every capsule, at research-backed doses.
Third, one bottle is a full 3-month supply (90 capsules) — most brands give you only 30 days.
Fourth, it's doctor-formulated by a specialist in anti-aging endocrinology, not a generic vitamin company.
And fifth, it has a 12+ year track record with 2813+ reviews from customers who've seen their blood levels finally move into the optimal range.
Each bottle is a full 3-month supply — exactly the window needed to meaningfully raise your Vitamin D levels and see measurable improvement on a blood test. But here's the important reality: maintaining optimal Vitamin D and K2 levels is a lifelong health priority. When you stop, levels drop again — especially through winter months or if you have limited sun exposure year-round. Most of my customers choose monthly auto-ship, which saves 20% and ensures they never run out; or multi-bottle packs, which offer the lowest price per bottle and keep you stocked for 6–9 months without thinking about it. Both options protect your progress.
You're covered by two layers of protection. First, all of our products come with a one-year satisfaction guarantee. However, we take it a step further: improved Vitamin D levels within 30 days, or pay nothing AND receive an additional $100 cash back.
That's how confident we are that you'll see and feel the difference. We can make such a powerful guarantee because we've been in business since 1999 and have 27+ years of proof with thousands of positive reviews.
