Vitamin K2 (MK-7) & Vitamin D3 (5000 IU) & Black Pepper Extract
Wild Foods Vitamin K2 (MK-7) + Vitamin D3 5,000 IU + Black Pepper Extract | 60 Capsules
✓ Third-Party Tested ✓ Non-GMO ✓ Gluten-Free & Soy-Free ✓ Plant-Based Capsule ✓ Made in USA
Wild Foods delivers one of the most intelligently formulated daily wellness supplements available with their Vitamin K2 (MK-7) + Vitamin D3 + Black Pepper Extract capsules — a precision-dosed, three-ingredient combination engineered to work as a synergistic system rather than isolated nutrients. Each of the 60 plant-based capsules delivers 5,000 IU of Vitamin D3 (as cholecalciferol) paired with 100mcg of Vitamin K2 as MK-7 (Menaquinone-7) — the superior, long-acting form of K2 — plus Black Pepper Extract to amplify absorption of both fat-soluble vitamins. This is the clinically calibrated ratio: 100mcg of K2 per 5,000 IU of D3, precisely matched to ensure that the calcium mobilized by D3 is properly directed to bones and away from arterial walls. An estimated 40% or more of adults are deficient in Vitamin D3, and most D3-only supplements leave out the K2 that makes the formula actually work as intended. Wild Foods corrects both gaps in a single, no-filler capsule — non-GMO, soy-free, gluten-free, and manufactured in the USA under stringent quality controls.
What Makes This Product Unique
- MK-7 — The Superior Form of Vitamin K2 - MK-7 (Menaquinone-7) remains active in your bloodstream for up to 72 hours per dose. Compare that to MK-4, which is eliminated within 6 hours. One daily capsule of MK-7 keeps K2 working around the clock — activating bone-building and arterial protection proteins continuously.
- Clinically Calibrated Dosing Ratio - 5,000 IU of D3 with 100mcg of K2 MK-7 is the ratio consistently recommended by nutrition researchers for optimal calcium metabolism. This isn't a random blend — it's a specific, purposeful formulation.
- Black Pepper Extract for Enhanced Bioavailability - Piperine, the active compound in black pepper, inhibits the metabolic enzymes that would otherwise break down fat-soluble nutrients in the digestive tract, significantly increasing how much D3 and K2 your body actually absorbs and retains from each capsule.
- Zero Filler Policy - Wild Foods formulates without unnecessary binders, flow agents, or artificial additives. The capsule is plant-based cellulose and what's inside is exactly what the label says — nothing more.
- Third-Party COA Tested on Every Batch - Every Wild Foods product is independently lab-tested for purity, potency, heavy metals, and microbial safety before it ships. Not a marketing claim — a verifiable, batch-by-batch standard.
- Plant-Based and Broadly Inclusive - Non-GMO, soy-free, gluten-free, and made with a plant cellulose capsule — suitable for vegetarians and those with common dietary sensitivities.
- Farm-Level Sourcing Transparency - Wild Foods sources ingredients as close to the farm as possible, maintaining a short, transparent supply chain rather than relying on anonymous multi-tier commodity brokers. You know what you're getting and where it comes from.
Key Benefits
- Supports Bone Density and Strength - D3 drives calcium absorption in the gut while K2 (MK-7) activates osteocalcin — the protein that physically binds calcium to bone matrix. Together they deliver the full bone-building benefit that neither nutrient can achieve alone.
- Promotes Healthy Cardiovascular Function - K2 activates Matrix Gla Protein (MGP), which inhibits calcium from depositing in arterial walls and soft tissue. Taking D3 without K2 may allow excess calcium to go where you don't want it — this formula corrects that.
- Supports Immune System Regulation - Vitamin D3 receptors are found on virtually every immune cell in the body. Adequate D3 levels are consistently linked to a well-regulated, responsive immune system — particularly important during fall and winter months when sun exposure drops.
- Contributes to Brain and Nervous System Health - Vitamin D3 functions as a neuroactive hormone, and receptors for it are distributed throughout the brain. Maintaining optimal serum D levels is consistently associated with better mood regulation, mental clarity, and cognitive support.
- Helps Maintain Healthy Teeth - The same calcium regulation mechanisms that reinforce bone structure also govern dental mineralization. D3 and K2 together provide the essential cofactors for strong, healthy tooth enamel.
- Year-Round Vitamin D Maintenance - Unlike sun-dependent D3 synthesis — which drops dramatically in winter, in cloudy climates, and for anyone spending most of their day indoors — this formula maintains consistent daily levels regardless of season or geography.
- Maximum Absorption with Every Capsule - The addition of Black Pepper Extract means your body extracts and retains significantly more of the D3 and K2 from each dose rather than passing unused nutrition through the digestive tract.
How It Works
Vitamin D3 (cholecalciferol) is technically a fat-soluble hormone precursor — the same compound your skin synthesizes when exposed to UVB radiation. Once ingested, D3 is converted in the liver and kidneys into its active hormonal form, calcitriol, which regulates the absorption of calcium and phosphorus in the small intestine and plays a critical role in immune cell function, mood regulation, and neurological health. Despite how fundamental D3 is to normal physiology, an estimated 40% or more of adults in the developed world are deficient — a number that climbs sharply among people who work indoors, live above the 35th parallel, are over age 50, or have darker skin tone that reduces UVB synthesis efficiency. A daily 5,000 IU supplement is a well-studied approach to restoring and maintaining optimal serum 25(OH)D levels throughout the year.
Here is the critical problem with most D3-only supplements: D3 drives calcium absorption but does not direct where that calcium goes. Without adequate Vitamin K2, the extra calcium mobilized by D3 can accumulate in soft tissues — including arterial walls — rather than being deposited into bone where it belongs. K2 (as MK-7) activates two proteins that govern this calcium traffic: osteocalcin, which locks calcium into bone matrix, and Matrix Gla Protein (MGP), which actively inhibits calcium from building up in blood vessels. This is why researchers in the field consistently argue that D3 and K2 are biochemically co-dependent and should always be taken together.
The choice of MK-7 over MK-4 as the form of K2 is not a minor detail. Both forms are absorbed effectively, but MK-4 has a serum half-life of only a few hours — meaning it is largely cleared before it can fully activate K2-dependent proteins. MK-7, derived from fermented natto, has a serum half-life of up to 72 hours. A single daily dose maintains consistent, therapeutically active K2 levels in the bloodstream throughout the entire day and night, ensuring that osteocalcin and MGP remain activated continuously.
Black Pepper Extract (piperine) rounds out this formula by addressing a common limitation of fat-soluble supplement absorption. Piperine works by inhibiting CYP3A4 and P-glycoprotein — metabolic enzymes and transporters in the intestinal wall and liver that would otherwise degrade or limit the uptake of fat-soluble compounds. The result is meaningfully improved bioavailability and retention of both D3 and K2, so that the doses on the label are the doses your body actually gets to use.

How to Use
Serving Size: 1 Capsule
Servings Per Container: 60
Directions: Take one capsule daily. For significantly better absorption, take with a meal that contains healthy dietary fat — eggs, avocado, olive oil, nuts, or full-fat dairy. D3 and K2 are both fat-soluble vitamins and absorb substantially better in the presence of dietary fat. Some adults take 2 capsules daily based on physician guidance — consult your healthcare provider before exceeding the label dose.
Best Taken: Morning with a fat-containing meal is the most common approach. If you take other fat-soluble vitamins (A, E, or K), combining them at the same meal is perfectly fine and may improve overall uptake efficiency.
Storage: Store in a cool, dry place away from direct sunlight and heat. Keep the bottle tightly sealed between uses. Avoid storing in the bathroom — humidity and temperature fluctuations accelerate potency degradation.

Frequently Asked Questions
What is Vitamin K2 (MK-7) and why does it need to be taken with Vitamin D3?
Vitamin K2 (as MK-7) is a fat-soluble vitamin that activates two critical proteins governing how your body manages calcium: osteocalcin, which physically binds calcium to bone tissue, and Matrix Gla Protein (MGP), which prevents calcium from depositing in arterial walls and soft tissue. When you take Vitamin D3 alone, it increases calcium absorption from your gut — but without K2, that extra calcium has no instructions and can end up in places you don't want it. K2 acts as the calcium traffic director, routing it into bones and keeping it out of arteries. The MK-7 form is preferred over MK-4 because it has a serum half-life of up to 72 hours, meaning a single daily dose maintains active K2 levels around the clock. MK-4 clears from circulation within hours.
Is 5,000 IU of Vitamin D3 per day safe? Why this dose?
5,000 IU is a widely used therapeutic dose for adults looking to correct deficiency and maintain optimal serum 25(OH)D levels. While official recommended dietary allowances are lower, many clinicians routinely recommend 5,000 IU for patients with documented deficiency — which affects an estimated 40% or more of adults. The key safety factor is pairing it with adequate K2, which this formula does at the clinically recommended 100mcg MK-7 per 5,000 IU of D3. If you have concerns about your specific dose or want to confirm your current vitamin D status, ask your doctor for a simple 25(OH)D blood test.
How do I take Wild Foods K2 + D3? Any tips for better absorption?
Take one capsule daily with a meal that contains dietary fat — eggs, avocado, olive oil, nuts, or full-fat dairy all work well. D3 and K2 are both fat-soluble vitamins, meaning they dissolve in fat and are absorbed far more efficiently when consumed alongside dietary fat versus on an empty stomach. Research shows fat intake at the same meal can increase fat-soluble vitamin absorption by 30–50%. The Black Pepper Extract in this formula also enhances uptake by reducing enzymatic breakdown in the gut. Morning is the most common time to take it, but any meal works.
Where can I buy Wild Foods Vitamin K2 + D3 + Black Pepper Extract online?
You can purchase Wild Foods Vitamin K2 (MK-7) + D3 5,000 IU directly here at Masterpiece Alternatives. We carry an expanding selection of Wild Foods products alongside our full supplements collection — all authentic, sourced directly, and shipped fast. No third-party marketplace markups, no questionable sellers.
Is this product third-party tested? How do I know it's legitimate?
Yes. Wild Foods requires third-party Certificate of Analysis (COA) testing on every batch across their product line. This covers purity, potency, heavy metal content, and microbial safety. It is a non-negotiable manufacturing standard for Wild Foods — not a selective marketing claim applied to flagship products only. Lab results are available on the product label. We also vet every brand we carry at Masterpiece Alternatives for proper lab testing and quality documentation before we list their products.
What other supplements pair well with D3 + K2? Can I stack these?
D3 + K2 is a foundational supplement that stacks well with almost any daily wellness protocol. The most impactful additions: Magnesium is critical — it is required for D3 to be converted to its active form, and many people who don't respond well to D3 supplementation are actually magnesium deficient underneath. Vitamin C provides complementary immune support and directly enhances the immune benefits you're getting from D3. A methylated multivitamin fills out any remaining micronutrient gaps so your entire nutritional foundation is covered. We carry the Wild Methylated Multivitamin and NutraChamps Vitamin C Gummies — both solid stack additions alongside your D3 + K2. Browse our full supplements collection for more options.
How long does it take for Vitamin D3 + K2 to work? When will I notice results?
Vitamin D3 is not a fast-acting supplement in the way stimulants or adaptogens are. It works by restoring and maintaining adequate serum levels over time. Most people who were meaningfully deficient report noticeable improvements in energy, mood stability, and immune resilience within 4–8 weeks of consistent daily use. The bone density and cardiovascular benefits of K2 + D3 are a longer-term process best confirmed through bloodwork (25(OH)D testing) and, if indicated, bone density scans over several months. Consistency is the most important factor — this is a daily maintenance supplement, not a one-week protocol.
Who should take D3 + K2, and who should use caution?
Most adults benefit from D3 + K2 supplementation, especially those who work indoors, live in northern climates with limited winter sunlight, are over age 50 (skin synthesis efficiency declines with age), follow a strict vegan or dairy-free diet, or have been told by a doctor their vitamin D levels are suboptimal. Use caution if you take blood-thinning medications such as warfarin (Coumadin) — Vitamin K2 interacts with anticoagulant therapy and you should consult your physician before adding any K2 supplement. Individuals with hypercalcemia or certain rare metabolic conditions should also speak with their doctor before starting high-dose D3.
How should I store this product, and what is its shelf life?
Store in a cool, dry place away from direct sunlight, heat, and humidity. Keep the bottle tightly closed between uses. Avoid storing in the bathroom — the temperature and moisture fluctuations in bathrooms are among the fastest ways to degrade supplement potency. Stored properly, this supplement maintains full potency through the printed expiration date on the bottle. Do not use after the expiration date.
