Unlike cow’s milk, almond milk isn’t naturally high in calcium—it needs to be fortified. Research suggests that the added calcium in plant-based drinks isn’t absorbed as well into the body as the naturally occurring calcium in cow’s milk.¹

Take a stroll through your local supermarket, and you’ll find a variety of almond milk options. While some are fortified with calcium, they still provide about 40% less of this essential mineral compared to cow’s milk.²

The Australian Dietary Guidelines encourage us to enjoy a variety of dairy options like milk, cheese, and yogurt, backed by solid scientific evidence linking them to a lower risk of heart disease, stroke, high blood pressure, and type 2 diabetes. Plus, research shows there’s no need to worry about dairy and weight gain or obesity.

The guidelines say, for those exploring dairy alternatives like almond milk, to make sure it's fortified with at least 100mg of calcium per 100mL.³ Keep in mind, although fortified almond milk is a better choice than unfortified, it still doesn't quite match the natural goodness of cow’s milk, which boasts more protein and a unique blend of easily absorbed nutrients that are hard to replicate.

Switching from cow’s milk to almond milk could contribute to lower levels of calcium.⁴ This vital mineral supports healthy bones, muscles, and heart function. Inadequate calcium can lead to osteoporosis, which is one of the major contributors to disease burden in Australia. This is especially true among older Australians, particularly postmenopausal women.⁵ Cow’s milk is an excellent source of absorbable dietary calcium. If you opt for almond milk, opt for a fortified brand to ensure you're getting enough calcium in your diet.
