Key Benefits of Z-JANS Vitamin D3 + K2 Capsules
Z-JANS Vitamin D3 + K2 Capsules carefully balanced formula ensures that calcium absorbed via Vitamin D is directed efficiently to the skeletal system rather than accumulating in the arteries. As featured on the nutrient panels in Z-JANS Vitamin D3 + K2 Capsules, each capsule delivers authorized benefits:
- Immune System Defence: Vitamin D contributes to the normal function of the immune system.
- Bone & Tooth Maintenance: Vitamin D and Vitamin K work synergistically to contribute to the maintenance of normal bones. Vitamin D also supports the maintenance of normal teeth.
- Muscle & Calcium Support: Vitamin D contributes to normal muscle function, normal blood calcium levels, and the normal absorption/utilization of calcium and phosphorus.
- Blood Coagulation: Vitamin K contributes to normal blood clotting.
- Antioxidant Additions: Includes a supporting dose of Vitamin C (as Calcium Ascorbate) which assists in cellular protection from oxidative stress.
Usage & Directions
To maximize bioavailability and ensure proper usage, follow the guidelines on Z-JANS Vitamin D3 + K2 Capsules bottle
Recommended Dose: Take 1 capsule daily.
- Administration: Swallow whole with a glass of water. Because Vitamins D3 and K2 are fat-soluble nutrients, it is highly recommended to take your daily capsule alongside a meal containing healthy fats to boost absorption.
- Storage: Store in a cool place, out of the reach and sight of children.
How Long Can It Be Used?
- Continuous Nutritional Support: This supplement can be used safely on a long-term, daily basis to support your routine nutrition.
- 60-Day Supply: Each bottle contains 60 capsules, providing a complete 2-month course when taking 1 capsule daily.
- Seasonality: While many in the UK choose to supplement with Vitamin D specifically from October to March, it can be taken year-round if your dietary intake or outdoor exposure is consistently low.
Side Effects
When adhered to the recommended dose, adverse effects are exceptionally rare. However, possible mild responses include:
- Mild digestive variations (nausea or slight stomach discomfort) if taken on an entirely empty stomach.
- Minor headaches in rare cases of initial adjustment to high-strength fat-soluble vitamins.

Contraindications & Warnings
Please read the mandatory UK safety compliance instructions on Z-JANS Vitamin D3 + K2 Capsules before starting:
- Do not exceed the stated recommended dose.
- Food supplements should not be used as a substitute for a varied and balanced diet, and a healthy lifestyle.
- Anticoagulant Precaution (Crucial): This product contains Vitamin K2. If you are taking any prescribed blood-thinning medications (such as Warfarin or other anticoagulants), you must consult your GP or haematologist before use, as Vitamin K directly influences blood clotting.

Got Questions? We've Got Answers
Q: Where is this product manufactured?
A: Z-JANS Vitamin D3 + K2 Capsules is proudly manufactured in the United Kingdom for Z-JANS Nutraceuticals Ltd
Q: Why are Vitamin D3 and Vitamin K2 paired together?
A: They are the ultimate nutritional partners. Vitamin D3 increases your body’s absorption of calcium from food. Vitamin K2 acts as the “director,” ensuring that calcium is deposited safely into your bones and teeth, rather than lingering in your blood vessels or soft tissues.
Q: What is the exact strength of the vitamins in each capsule?
A: According to the official supplement table on Z-JANS Vitamin D3 + K2 Capsules, each single capsule provides a high-strength dose of 100µg (4000IU) of Vegan Vitamin D3 (2,000% Reference Intake) and 200µg of Vitamin K2 (MK-7) (267% Reference Intake).
Q: Is this product suitable for a vegan lifestyle?
A: Yes. Unlike standard Vitamin D3 which is often sourced from sheep’s wool (lanolin), Z-JANS uses a premium, plant-derived, vegan source of Vitamin D3. The capsule shell is made from plant-based Hydroxypropyl Methylcellulose (see Z-JANS Vitamin D3 + K2 Capsules bottle).
Q: Is the Z-JANS Vitamin D3 + K2 supplement Halal?
A: Yes, the back panel explicitly features an official Halal stamp alongside its Vegan certification icon guaranteeing compliance with dietary preparation standards.
