About Vitamin D3 + K2 (MK-7) With Vitamin C Tablets

Our Vitamin D3 + K2 (MK-7) with Vitamin C combines microencapsulated vitamin D3 (5000 IU), high-potency vitamin K2 as MK-7, and stabilizing vitamin C in convenient tablet form. This formula supports immune function, promotes bone health, and helps maintain cardiovascular wellness while delivering superior absorption even when taken without food.

Our Vitamin D3 + K2 Story

Most vitamin D supplements fall short in two critical areas: poor absorption when taken on an empty stomach, and the absence of complementary nutrients that maximize vitamin D's benefits. Traditional vitamin D3 requires dietary fats for optimal absorption, making it problematic for those practicing intermittent fasting or preferring morning supplementation without food. Taking vitamin D alone also misses the powerful synergy with vitamin K2 that supports both bone health and cardiovascular function.

Advanced microencapsulation technology addresses these limitations by creating pre-formed micelles around both the vitamin D3 and K2, dramatically improving absorption regardless of food intake. We selected MK-7, the most bioavailable and longest-lasting form of vitamin K2, sourced from fermented soy natto. Vitamin C acts as a natural antioxidant that prevents the oxidation of both fat-soluble vitamins during storage, ensuring long-term stability and potency.

This formulation delivers 5000 IU of vitamin D3 alongside 100 mcg of vitamin K2 MK-7, providing the optimal ratio for supporting calcium metabolism, bone mineralization, and arterial health. The microencapsulated delivery system makes this ideal for anyone seeking consistent vitamin D benefits without the constraints of meal timing or dietary fat requirements.

Benefits

• Supports Immune System: Vitamin D3 enhances immune cell function and regulates immune responses, while vitamin C provides antioxidant protection to support your body's natural defenses.
• Promotes Bone Health: The 5000 IU vitamin D3 increases calcium absorption in the intestines, while vitamin K2 as MK-7 directs calcium to bones and teeth where it belongs, supporting optimal bone density and strength.
• Supports Cardiovascular Health: Vitamin K2 helps prevent arterial calcification by activating proteins that keep calcium out of arteries, while vitamin D3 supports healthy blood pressure already within normal range.
• Reduces Oxidative Stress: Vitamin C acts as a powerful antioxidant that neutralizes free radicals and protects cells from damage, while also stabilizing the vitamin D3 and K2 to maintain their potency.

The microencapsulated forms of both vitamin D3 and K2 enhance absorption even when taken without food, making them ideal for those practicing intermittent fasting or preferring to take their nutritional supplements earlier in the day. The delivery system maximizes the bioavailability of both fat-soluble vitamins, ensuring you get the full benefit of each dose while supporting multiple aspects of cellular health.

Quality and Standardization

• Microencapsulated Technology: Our vitamin D3 and K2 undergo advanced microencapsulation processing that creates protective lipid barriers around each nutrient molecule, significantly improving absorption rates even when taken on an empty stomach during intermittent fasting protocols.
• High-Purity Vitamin K2 MK-7: We source our vitamin K2 exclusively as menaquinone-7 from fermented soy natto, providing the most bioavailable and longest-lasting form of vitamin K2 with a half-life of 72 hours compared to other vitamin K variants.
• Stabilizing Vitamin C Matrix: Each tablet contains precisely dosed ascorbic acid that acts as a natural antioxidant preservative, preventing oxidative degradation of both vitamin D3 and K2 throughout the product's shelf life and maintaining potency integrity.
• Third-Party Testing Verification: Every batch undergoes comprehensive testing at our third-party labs for identity, purity, and potency confirmation, with certificates of analysis available to ensure you receive exactly 125 mcg vitamin D3, 100 mcg vitamin K2, and 60 mg vitamin C per tablet.
• Pharmaceutical-Grade Manufacturing: We produce these tablets in cGMP-certified facilities using precise compression techniques that ensure uniform nutrient distribution and consistent dissolution rates for optimal bioavailability across the entire vitamin D supplements category.

Mechanism of Action

• Vitamin D Receptor Activation: Vitamin D3 converts to calcitriol, the active hormone form that binds to vitamin D receptors throughout the body, including immune cells, bone tissue, and muscle fibers, triggering gene transcription that regulates calcium metabolism and immune responses.
• Calcium Transport Regulation: Activated vitamin D3 upregulates synthesis of calbindin proteins in the intestines, which serve as calcium-binding transport molecules that dramatically increase calcium absorption efficiency from dietary sources.
• Osteocalcin Carboxylation: Vitamin K2 as MK-7 serves as a cofactor for gamma-carboxylase enzymes that activate osteocalcin, a bone matrix protein that binds calcium ions and directs them into bone tissue rather than allowing arterial deposition.
• Matrix Gla Protein Activation: K2 also carboxylates matrix Gla protein (MGP), a powerful inhibitor of vascular calcification that prevents calcium from accumulating in arterial walls and soft tissues, supporting cardiovascular health.
• Antioxidant Protection: Vitamin C acts as a reducing agent that prevents oxidative degradation of both fat-soluble vitamins D3 and K2, while also regenerating other antioxidants like vitamin E and supporting cellular health through collagen synthesis pathways.

Overview of the Science

The synergistic relationship between vitamin D3 and vitamin K2 extends beyond basic nutrient support to cellular-level optimization. Research demonstrates that vitamin D and K work together to regulate calcium transport proteins and matrix Gla proteins, which coordinate bone mineralization and prevent soft tissue calcification [1]. This partnership becomes particularly important as vitamin D enhances calcium absorption in the intestines, while K2 directs that calcium to appropriate tissues rather than allowing arterial deposits. The microencapsulation technology applied to both nutrients creates phospholipid barriers that mimic natural fat digestion, allowing effective absorption even during fasted states when bile acid production is minimal.

Vitamin C serves a dual protective role in this formulation, functioning both as a stabilizing antioxidant and a cofactor for collagen synthesis pathways that work downstream from vitamin D and K2 signaling. The ascorbic acid prevents oxidative degradation of the fat-soluble vitamins during storage while supporting the enzymatic processes that convert vitamin D3 to its active metabolite calcitriol. This creates a comprehensive foundation for cellular health supplements that addresses multiple physiological pathways simultaneously, making it particularly valuable for individuals seeking comprehensive nutritional supplements that work synergistically rather than in isolation.
