INVITA ADK Vitamin Supplement – 90 Capsules – Vitamin A, D3 5000 IU & K2-MK7

Key Health Benefits of the ADK Combination

Vitamins A, D3, and K2 (as MK-7) each play distinct roles in maintaining your health. Vitamin D contributes to the normal absorption and utilisation of calcium and phosphorus, while vitamin K contributes to normal blood clotting and maintenance of normal bones. Vitamin A contributes to maintenance of normal mucous membranes, normal skin, and normal vision. Together, this trio offers comprehensive support for bone health, immune function, and overall vitality.

• Bone Health Support: Vitamin D helps the body absorb calcium, and vitamin K (as MK-7) contributes to the maintenance of normal bones by activating proteins that bind calcium to the bone matrix.
• Immune Function: Vitamin D contributes to the normal function of the immune system, while vitamin A helps maintain the health of immune barriers such as skin and mucous membranes.
• Healthy Vision and Skin: Vitamin A is essential for normal vision and contributes to the maintenance of normal skin.
• Normal Blood Clotting: Vitamin K contributes to normal blood clotting, supporting cardiovascular integrity.

Why Take Vitamin A, D3, and K2 Together?

Taking these three fat-soluble vitamins together creates a synergistic effect. Vitamin D3 increases calcium absorption, but without vitamin K2, calcium might not be directed to the bones and teeth. Vitamin K2 activates proteins that help bind calcium to the bone matrix while preventing its deposition in soft tissues. Vitamin A complements this by supporting the tissues that rely on calcium regulation, such as bones and teeth. This balanced combination ensures your body uses these nutrients efficiently.

The INVITA ADK supplement is formulated by a doctor to deliver high-potency doses in a single capsule. With 5000 IU of vitamin D3 (as cholecalciferol) and 500 mcg of vitamin K2 (as menaquinone-7, MK-7), plus a meaningful amount of vitamin A (as palmitate), this formula is designed for adults seeking robust foundational support.

Understanding the Synergy: How These Vitamins Work Together

Vitamin D3 stimulates the production of calcium-binding proteins in the gut, enhancing calcium absorption. Vitamin K2 then activates osteocalcin, which helps bind calcium to the bone matrix, and matrix GLA protein (MGP), which may help keep calcium from accumulating in blood vessel walls. This teamwork supports bone density and cardiovascular health.

Vitamin A further supports this process by maintaining the health of mucous membranes and acting as an antioxidant to protect cells from oxidative stress. Together, these three vitamins create a balanced framework for strong bones, a resilient immune system, and overall wellbeing.

What to Look For in an ADK Supplement

When choosing an ADK supplement, consider the form and dosage of each nutrient. For vitamin D3, 5000 IU is a common high-potency dose suitable for those with limited sun exposure or higher needs. Vitamin K2 should ideally be in the MK-7 form, as it is more bio-available and remains active in the body longer than MK-4. Vitamin A is best as palmitate (preformed) for optimal absorption.

The INVITA ADK supplement meets these criteria: it uses vitamin D3 from lanolin, vitamin K2 as MK-7 from natto (fermented soya), and vitamin A as palmitate. The product is manufactured in the USA, third-party tested for purity and potency, and free from common allergens (non-GMO, gluten-free, dairy-free, no artificial additives). It is also suitable for vegetarians (vegetarian capsules).

Recommended Dosage and Usage

For adults, take one (1) capsule daily with food. Because vitamins A, D3, and K2 are fat-soluble, taking them with a meal containing dietary fat (such as healthy oils, avocado, or nuts) enhances absorption. Store in a cool, dry place away from direct sunlight. As with any supplement, consult your health care provider before starting a new regimen, especially if you are pregnant, nursing, or have a medical condition.

Food supplements should not be used as a substitute for a varied and balanced diet and a healthy lifestyle. These statements have not been evaluated by the Medicines and Health care products Regulatory Agency (MHRA).
