Support normal bones¹, teeth¹ and immune function¹ with our Vitamin D3 + Calcium bundle

Product option image

Do you want to support your bones as you age?

Calcium is needed for the maintenance of normal bones and teeth, while vitamin D3 contributes to normal absorption of calcium. Together, they work in harmony every day and support your body, no matter your age.

Are you following a lifestyle that limits both nutrients?

If you’re plant-based, don’t eat dairy, work indoors, or live in a climate with limited sunlight, this combination ensures you’re meeting your daily requirements for vitamin D3 and calcium.

Are you concerned about getting enough vitamin D3 and calcium every day?

One daily serving provides 1000 IU of vitamin D3 (500% NRV) and 800 mg of calcium (100% NRV), making it easier to meet your daily requirements—especially when diet or lifestyle falls short.

Why does this formula contain two calcium sources?
Calcium citrate and calcium lactate are highly bioavailable forms of calcium. Using both helps ensure efficient absorption and reliable daily intake.

Why powder form works better

  • Better absorption
    Liquid supplements allow for better bioavailability of both nutrients compared to compressed tablets, meaning your body can utilize both calcium and vitamin D effectively.
  • Perfect nutrient combination
    Taking both nutrients together optimizes calcium absorption, as vitamin D3 contributes to normal absorption and utilisation of calcium (and phosphorus).
  • Integrate it easily into your life
    Add to your morning smoothie, post-workout drink, or evening routine. One simple step covers both your calcium and vitamin D3 needs.
  • Skip the pills
    Skip the hassle of taking multiple supplements. Our formula dissolves instantly and completely, eliminating the gritty residue of tablets.
  • Consistency is key
    The easier and more enjoyable it is to take, the more likely you are to maintain consistent daily intake. And with supplements, consistency is everything.
