Vitamin D3 and K2 with Zinc - High Strength 4000IU Vitamin D & K2 MK7 Formula - Includes Boron & MCT Oil for Optimal Absorption - 120 Capsules (4 Month Supply) - No Fillers - Made in The UK

Main Highlights

Vitamin D3 and K2 High Strength Capsules with No Fillers - Our clean 5-in-1 formula delivers Vitamin D3 (4000 IU), Vitamin K2 MK-7 (90mcg), Zinc, Boron and MCT oil in one daily capsule. Unlike many vitamin d and k2 supplements, ours contains NO artificial fillers—just pure ingredients that contribute to normal immune function, bone health and calcium absorption. Maximum benefits, minimum additives.

An Easy Way To Top Up Your Vitamin D - Each bottle contains a 4-month supply of easy-to-swallow, odourless capsules. Every serving contains both Vitamin D3 and K2 in their most absorbable forms. We've crafted a perfectly unique formula, intertwining a ratio-mixed blend of ingredients to support the bioavailability of Vitamin D3.

Why You Should Take Vitamins D3 And K2 Together To Support Your Immune System - In the correct dosage, Vitamin D3* and K2** regulate and control the body's effectiveness and efficiency in absorbing phosphorus and calcium, which are essential for bone and teeth health. Current evidence supports the joint supplementation of Vitamins D and K for bone health rather than taking each vitamin separately.

Enhanced Absorption with Zinc, Boron and MCT Oil - Our formula includes Zinc Citrate which contributes to normal immune function, maintains normal testosterone levels and helps protect cells from oxidative stress. We've also added Boron, a mineral that helps metabolise Calcium and Magnesium. The MCT oil, extracted from coconuts, provides healthy fats essential for proper absorption of the fat-soluble Vitamins D and K2.

Pure Formula, UK-Made Quality Assurance - Unlike many competitors, our vitamin k2 and vitamin d supplements contain absolutely NO artificial fillers, bulking agents or anti-caking agents—just clean, active ingredients for optimal absorption. Manufactured to the highest standards in ISO, BRC UK and GMP licensed facilities, our clean formula is free from all main allergens including wheat, gluten, dairy and nuts, providing complete peace of mind with every dose.

Vitamin D Support Year-Round - Vitamin D contributes to the normal function of the immune system. Our high-strength vitamin d supplement provides 4000 IU (100mcg) per capsule—400% of the daily reference intake—making it an excellent choice during winter months or for those with limited sun exposure when maintaining adequate vitamin d levels can be more challenging.

Complete Nutritional Support - This k2 d3 vitamin supplements combination contains nutrients that contribute to the maintenance of normal bones. The addition of boron and zinc provides complementary nutritional support. This makes our supplement particularly suitable for active individuals, those mindful about bone health, and adults over 40 looking for comprehensive nutritional support.

Cleanforms Vegan Vitamin D3 1000iu with Vit-K2, Magnesium, Calcium, Zinc, Boron & Vit-A | 60 Capsules for Immune, Bone, and Heart Support | Promotes Vitamin D3 Effectiveness

Main Highlights

MADE WITH COFACTORS FOR OPTIMAL FUNCTION — Vitamin D does not work alone, its optimal function depends on other 'helper molecules' called cofactors. Our 'Vitamin D3 + Main Cofactors' sensibly combines the cofactors involved in the Vitamin D system in a single formulation. All nutrients are supplied as carefully selected premium active ingredients: Vit. K2 MK7 (all-trans K2VITAL), Magnesium, Calcium, Boron, Zinc, Vit. A in a balanced ratio.

SUPPORTS IMMUNITY, TEETH AND BONE HEALTH — Vitamin D holds a special place among vitamins. Unlike most vitamins that we get from food, we mostly produce vitamin D in our skin with the help of sunlight. Interestingly, Vitamin D isn't a vitamin in the traditional sense — it's actually a hormone precursor.

CLEAN FORMULA — We're dedicated to bringing you the cleanest supplements with only the active ingredients you need, without the ones you don't. We manufacture our vitamins right here in the UK without the use of artificial fillers, binders or bulking agents. Our formulations are always vegan, gluten free tested and 3rd party tested.

OPTIMAL SOLUTION FOR VITAMIN D DEFICIENCIES — While the NHS recommends at least 400 IU of Vitamin D daily, our formulation has the optimum dose of1000IU to prevent Vitamin D deficiency — Essential for year-round immune and musculoskeletal support.

2 MONTH SUPPLY — Each bottle contains 60 capsules (1 per day). Our packaging is non-breakable, infinitely recyclable, light and easy to travel with.
