K2+D3 Synergy capsule

Questions about K2+D3 Synergy, answered.

What is the benefit of combining calcium, vitamin K2, and D3?

Vitamin D3 helps your body absorb calcium, while K2 directs that calcium to the bones and away from soft tissues like arteries. When combined with a daily dose of calcium, these nutrients work together to support strong bones and cardiovascular health more effectively than any one alone.
What form of K2 is used in this product?

Our K2+D3 Synergy uses Vitamin K2 as menaquinone-7 (MK-7)—the most bioavailable and long-lasting form of K2, ideal for maintaining consistent blood levels and maximizing calcium metabolism.
Is this supplement suitable for daily use?

Yes. This product is designed for daily foundational support. Each serving provides 210 mg of calcium, 5,000 IU of D3, and 100 mcg of K2—science-backed dosages commonly recommended for bone, heart, and immune health.
Can I take this with other Labstead products?

Absolutely. K2+D3 Synergy pairs well with our other foundational supplements. There is no overlap in active ingredients, and the balanced calcium dose is suitable for most routines.
When is the best time to take K2+D3 Synergy?

For optimal absorption of all ingredients, take with a meal that contains healthy fats—like olive oil, eggs, or avocado—since both vitamins are fat-soluble and calcium is best absorbed with food.
Is this product vegan friendly?

No. The D3 in this formula is cholecalciferol sourced from lanolin (sheep’s wool), which is common in high-potency D3 supplements. It is not vegan, but is generally considered vegetarian-friendly depending on dietary preferences.

How to use:

Take 1 capsule daily with food, preferably a meal that contains healthy fats such as eggs, olive oil, or fatty fish like salmon. This supports optimal absorption of all three ingredients—vitamin D3, vitamin K2, and calcium.

For best results, take consistently at the same time each day—morning or early afternoon is ideal.

Your system, adapting.

Because calcium, vitamin D3, and vitamin K2 support physiological processes that develop over time, their effects are often subtle at first. This formula begins working from the first dose—providing bioavailable calcium, supporting its absorption (D3), and helping direct it to the bones and teeth while keeping soft tissues like arteries clear (K2).

With consistent daily use, this complete 3-in-1 synergy contributes to healthier bone metabolism, improved vascular function, and more efficient calcium utilization. These benefits build gradually and may not produce immediate, noticeable sensations—but they play a critical role in long-term skeletal, cardiovascular, and immune health.
