Everything you need to know:

Why is calcium so crucial for my body?

Calcium is the most abundant mineral in your body. Did you know it makes up 1.5 to 2% of your total body weight? And more than 99% of your body’s calcium is found in your bones.*

Calcium also contributes to normal muscle function, to normal blood clotting, to the normal function of digestive enzymes and more.

If you aren’t getting enough calcium from your diet, choose our calcium powder drink today.

Is my current diet giving me enough calcium?

Many adults struggle to meet their daily calcium needs through diet alone. If you’re avoiding dairy, following a plant-based diet, or simply not consuming enough calcium-rich foods daily, you might not be getting the amount your body requires.

Why should I care about calcium now if I feel fine?

Think of calcium as an investment in your future self. Your bones are constantly changing and rebuilding – this is a process that requires adequate calcium.

What makes powdered calcium different from tablets?

Calcium tablets can be large, difficult to swallow, and may not dissolve completely. Our powder dissolves instantly and completely, ensuring your body can actually utilize the calcium you’re taking.

Our customers also confirm it works

Did you know that more than 99% of calcium is found in your bones?*

Get 800 mg of calcium citrate for your bones, teeth and muscle function

Product option image
  • Are you thinking about your long-term bone health?

Calcium is needed for the maintenance of normal bones and teeth. With 800 mg per serving, you’re supporting this process.

  • Do you want to support your body’s fundamental functions?

Beyond bones and teeth, calcium contributes to normal muscle function and normal blood clotting, to normal energy-yielding metabolism and normal neurotransmission.

Calcium is also crucial for digestion, because it contributes to normal function of digestive enzymes.

  • Are you following a diet that might be low in calcium?

If you’re plant-based, lactose intolerant, or simply don’t consume enough dairy and leafy greens, our calcium ensures you’re meeting your daily requirements for this crucial mineral.

Choose our calcium

You already know calcium matters. Here’s why our calcium formula stands apart:

  • High-strength, bioavailable formula

Most people need around 800 mg of calcium daily. Our 800 mg serving covers 100% of the nutritional reference value.

  • Dual calcium source: calcium citrate and calcium lactate

Our formula combines two highly bioavailable forms of calcium. Calcium citrate is renowned for its superior absorption, while calcium lactate provides excellent solubility.

  • Designed for a modern lifestyle

Perfect for busy professionals, athletes, or anyone who needs reliable calcium support but struggles with large tablets or inconsistent dietary intake.

  • Refreshing citrus taste

Our calcium features natural orange and lemon flavours without added sugar, making your daily calcium intake something you look forward to.

Why powder form is better

  • Better absorption
    Liquid supplements can be absorbed more readily than compressed tablets, meaning your body can utilize the calcium more effectively.
  • Dosage flexibility
    Start with half a serving if needed, or adjust based on your individual requirements.
  • Integrate it easily into your life
    Add to your morning smoothie, in your post-workout drink, or before sleep. Make supplementation work for your lifestyle.
  • Easy to mix and dissolve
    We’ve all bought fizzy tablets that stick to the glass, or leave gritty residue. Our formula dissolves instantly, making your daily calcium intake pleasant.
  • Consistency is key
    The easier it is to take, the more likely you are to take it consistently. And with supplements, consistency is everything.

Start taking your calcium today

If you start taking calcium TODAY:

  • You support the maintenance of normal bones and teeth¹
  • You contribute to normal muscle function and blood clotting¹
  • You support normal energy-yielding metabolism¹
  • Calcium citrate for best absorption
  • High bioavailability
  • 800 mg of calcium per dosage

If you start taking calcium later:

  • You continue to rely solely on dietary sources
