Q: What type of calcium is used in Oatly products and how bioavailable is it?
A: Oatly is fortified with both calcium carbonate and calcium phosphate, with the majority coming from calcium carbonate. This has been proven to be a successful combination in terms of both taste and consistency in oat drinks. With regard to bioavailability, research has shown that calcium carbonate uptake is on par with calcium uptake from cow's milk, while the uptake of calcium phosphate is slightly lower.
That said, when considering the availability of calcium in foods, it's important to consider a multitude of factors in addition to calcium type, including the different combinations of food ingested, the total amount of calcium consumed, age and vitamin D status.
Oatly oat drinks contain 120mg calcium/100ml, the same amount as cow's milk. They're also a rich source of vitamin D, which supports normal calcium absorption and bone health, and they're also fortified with riboflavin and vitamin B12.
