Nootropics Depot Vitamin D3 + K2 with Vitamin C Tablets – 365 Count (5000 IU)

Key Benefits of a High-Potency Vitamin D Supplement

• Bone health support: Vitamin D contributes to normal absorption and utilisation of calcium and phosphorus, while vitamin K contributes to the maintenance of normal bones.
• Immune function: Both vitamin D and vitamin C contribute to the normal function of the immune system.
• Antioxidant protection: Vitamin C contributes to the protection of cells from oxidative stress.
• Convenient dosage: One tablet daily provides 5000 IU of vitamin D3—a level often recommended for maintaining optimal blood levels, especially for those with limited sun exposure.
• Year supply: With 365 tablets, you can maintain consistency without frequent reordering.

Understanding Vitamin D3, K2, and Vitamin C Synergy

Vitamin D3, or cholecalciferol, is the most bio-available form of vitamin D. It plays a key role in calcium absorption, bone mineralisation, and immune function. However, vitamin D3 alone may not be enough—it directs calcium into the bloodstream, and without adequate vitamin K2, calcium can accumulate in soft tissues rather than bones. Vitamin K2 helps activate proteins that guide calcium to where it’s needed most: bones and teeth.

Vitamin C adds another layer of support. As a water-soluble antioxidant, it helps protect cells from oxidative stress and supports collagen production, which is essential for healthy skin, joints, and blood vessels. The combination of these three nutrients in one tablet simplifies your supplement routine while delivering complementary benefits.

Who May Benefit from Daily Vitamin D3 + K2 + C?

This supplement may be suitable for individuals who:

• Live in northern latitudes or areas with limited year-round sunlight
• Spend most of their time indoors
• Have darker skin, which reduces natural vitamin D production
• Are over age 50, when skin synthesis becomes less efficient
• Follow a diet low in vitamin D-rich foods (fatty fish, fortified dairy)
• Want to support bone density and immune health with a combined nutrient approach

Always consult a health care professional before starting any new supplement, especially if you have existing health conditions or take medications.

How to Choose the Right Dosage and Form

Vitamin D dosage is measured in International Units (IU) or micrograms (mcg). The recommended daily allowance for most adults is 600–800 IU, but many experts suggest higher intakes of 1000–5000 IU for optimal blood levels, especially for those at risk of deficiency. This product provides 5000 IU (125 mcg) per tablet—a potent dose best suited for individuals who have confirmed low vitamin D levels or increased needs.

Tablets are a convenient and stable form. Unlike softgels or liquids, tablets are easy to handle and dose precisely. For best absorption, take with a meal containing some fat, as vitamin D is fat-soluble. The combination with vitamin K2 and C in a single tablet eliminates the need for multiple bottles.

Quality and Lab Testing Assurance

Nootropics Depot emphasises rigorous testing. Every batch is lab-tested to verify ingredient identity, potency, and purity. This commitment ensures that what’s on the label matches what’s inside the bottle—free from contaminants, heavy metals, or adulterants. The company sources high-quality raw materials and conducts research to optimise formulation. While individual results may vary, you can trust that the product meets strict quality standards.

What Makes This Supplement Stand Out?

Getting enough vitamin D can be a challenge, especially in the UK where sunlight is limited during the winter months. Many people turn to supplementation to maintain healthy levels, but not all vitamin D products are created equal. This vitamin D3 supplement from Nootropics Depot combines cholecalciferol (vitamin D3) with vitamin K2 and vitamin C in a convenient tablet form. With 125 mcg (5000 IU) of vitamin D3 per serving, a single bottle provides a full year’s supply—365 tablets designed for daily uses.

What sets this formula apart is the thoughtful inclusion of vitamin K2, which works synergistically with vitamin D3 to support calcium utilisation, and vitamin C, a powerful antioxidant that contributes to immune health. All ingredients are lab-tested for purity and potency, ensuring you receive a high-quality supplement backed by rigorous quality control.

Safety and Precautions

Vitamin D is safe at recommended doses, but excessive intake (above 10,000 IU daily over long periods) can lead to toxicity, causing hypercalcaemia and related issues. This product provides 5000 IU, which is within the tolerable upper intake level for adults but should not be combined with other high-dose vitamin D supplements without medical supervision. Vitamin K2 is generally safe, but if you take blood thinners like warfarin, consult your doctor before uses. Vitamin C is water-soluble and excess is excreted, but high doses may cause digestive upset in some individuals.

Store in a cool, dry place away from direct sunlight. Keep out of reach of children. Do not exceed the recommended dose.

This product is a food supplement. It should not be used as a substitute for a varied and balanced diet and a healthy lifestyle. If you are pregnant, breastfeeding, taking any medications, or have a medical condition, consult your doctor before uses.
