"A clear difference was noticeable after a few days of mixing it in their drinking water. Very satisfied." — Iris v.d.B., verified review

Why choose Calcium + Phosphorus Boost?

  • Supports against soft-shelled eggs — calcium and phosphorus for strong eggshells, addressing a common cause: a deficiency in these minerals
  • Better absorption via drinking water — minerals from solid feed often pass through undigested into the droppings; in liquid form, chickens absorb them much better
  • Strong bones and mobility — calcium and phosphorus support bone structure
  • Organic acids — contribute to a healthy drinking water environment by inhibiting the growth of bacteria, fungi, and yeasts

* This product itself contains no added vitamins — it is a pure mineral and organic acid formula. For vitamins such as D3 (important for calcium absorption), you can combine it with a separate vitamin supplement.

Who is this suitable for?

Suitable for all chicken breeds and other bird species. Especially valuable for laying hens with thin eggshells or soft-shelled eggs.

Soft-shelled eggs persist? A calcium or vitamin D deficiency is a common cause of soft-shelled eggs, but not the only one — age, stress, or a reproductive system disorder can also play a role. If you don't see improvement after a curative course, or if it's accompanied by other symptoms, consult a veterinarian.

Frequently asked questions

What's in Calcium + Phosphorus Boost?

Calcium, phosphorus, choline chloride, and organic acids, in liquid form for administration via drinking water.

How do I dose Calcium + Phosphorus Boost?

Curative: 10 ml per liter of drinking water for 5 to 14 days. Preventive: 10 ml per liter of drinking water, 2 to 3 consecutive days per week.

Why via drinking water instead of feed?

Minerals like calcium and phosphorus from solid feed are often poorly absorbed and end up undigested in the droppings. Chickens absorb them much better via drinking water.

Does this help with all soft-shelled eggs?

Calcium deficiency is a common cause of soft-shelled eggs, but not the only one. If the problem persists after a curative course, consult a veterinarian.

Does Calcium + Phosphorus Boost contain vitamin D3 or other vitamins?

No, this product itself contains no added vitamins — it is a pure mineral and organic acid formula (calcium, phosphorus, sodium, choline chloride). If you also want to add vitamins such as D3, combine it with a separate vitamin supplement.

Is this suitable for birds other than chickens?

Yes, suitable for all chicken breeds and other bird species.

How do I store Calcium + Phosphorus Boost?

Store in a cool, dark place, away from direct sunlight and extreme temperatures, for the longest shelf life.
