Lactase calcium relationship

Definition

Lactase is an intestinal enzyme that digests lactose in milk. The absence or inadequacy (lactose intolerance) may complicate the consumption of dairy products, a major source of calcium.

How it works

The lactase enzyme breaks down lactose, the natural sugar in milk, into absorbable glucose and galactose. In lactose intolerant individuals, this enzyme is deficient or absent, causing bloating, discomfort, and diarrhea after milk consumption. This represents a major nutritional challenge as dairy products are the most bioavailable and accessible calcium sources.

Role

Lactase facilitates the absorption of dairy calcium by allowing lactose digestion.

Examples

• Classic half-skim milk • Ricotta cheese • Natural yogurt • Lactose-free milk • Aged cheeses

Recommendations

If you are lactose intolerant, prefer yogurt and cheese where bacteria have already fermented lactose. Consume calcium-enriched lactose-free milk. Diversify your sources with broccoli, kale, and fortified plant-based beverages. Test your tolerance with small portions.

Key takeaway

Lactose intolerance does not prevent achieving calcium needs with suitable alternatives.
