Dr. Berg Maximum Strength Vitamin D3 K2 Liquid Drops with MCT Oil - 5,000 IU D3 + 50 mcg K2 MK-7 - Unflavoured, 30 ml

Key Health Benefits

Discover Berg Maximum Strength — Taking vitamin D3 and K2 together offers several important benefits supported by European Food Safety Authority (EFSA) health claims. Vitamin D3 contributes to the normal absorption and utilisation of calcium and phosphorus, the maintenance of normal bones, teeth, muscle function, and the normal function of the immune system. Vitamin K2 contributes to the maintenance of normal bones. This powerful duo works synergistically to help direct calcium to where it is needed most – your bones and teeth – rather than allowing it to accumulate in soft tissues. Users of this liquid formula have reported marked improvements in their vitamin D levels, especially those with limited sun exposure or irregular lifestyles.

Why Take Vitamin D3 and K2 Together?

Vitamin D3 and vitamin K2 form one of the most important nutrient partnerships for whole-body wellness. While vitamin D3 helps your body absorb calcium from the foods you eat, vitamin K2 directs that calcium to your bones and teeth, supporting healthy calcium balance and normal bone density. This synergistic action is crucial for maintaining skeletal strength and overall vitality. Many people take vitamin D3 alone, but without adequate K2, calcium may not be properly utilised. Dr. Berg Maximum Strength Vitamin D3 K2 Liquid Drops combine 5,000 IU of vitamin D3 with 50 mcg of vitamin K2 as MK-7 for superior support.

Understanding the Synergy: How D3 and K2 Work Together

The synergy between vitamins D3 and K2 is rooted in their complementary roles in calcium metabolism. Vitamin D3 (cholecalciferol) supports the production of calcium-binding proteins in the intestinal lining, enhancing calcium absorption. Once calcium enters the bloodstream, vitamin K2 (menaquinone-7) helps activate matrix GLA protein (MGP) and osteocalcin. MGP helps maintain arterial flexibility by keeping calcium from accumulating in vessel walls, while osteocalcin helps incorporate calcium into the bone matrix for density and strength. This two-step process ensures that calcium is directed to the skeleton rather than being deposited in soft tissues. Dr. Berg’s liquid formula delivers both nutrients in a highly absorbable form – vitamin D3 suspended in MCT oil and vitamin K2 as the more bioavailable MK-7 form, which stays active in the body longer than MK-4.

What to Look For in a D3 + K2 Supplement

Not all D3 and K2 supplements are created equal. When choosing a product, consider the following factors:

• Dosage Ratio: A common effective ratio is 5,000 IU of vitamin D3 with 45–100 mcg of vitamin K2. Dr. Berg’s formula provides 5,000 IU D3 and 50 mcg K2 MK-7.
• Form of K2: MK-7 is preferred because it has a longer half-life and provides sustained support throughout the day. The liquid formula ensures easy absorption.
• Delivery System: MCT oil enhances the absorption of fat-soluble vitamins D and K. This liquid drop form is convenient and quickly absorbed.
• Purity and Testing: Look for third-party testing, non-GMO, and gluten-free certifications. Dr. Berg’s product is third-party tested in a GMP-certified facility and free from artificial additives.

The liquid format is ideal for those who dislike swallowing pills – just shake well and take one dropperful daily.
