Prescription Nature Lactase is a dietary supplement containing lactase, the enzyme that breaks down lactose—milk sugar—into glucose and galactose. Lactase improves the digestion of lactose in people who have difficulty digesting it.
Each Prescription Nature Lactase vegetarian capsule contains 200 mg of lactase, equivalent to an enzymatic activity of 20,000 FCC. Lactase is the enzyme that breaks down lactose, the sugar found in milk, into two simpler sugars: glucose and galactose. When the intestine produces too little of it, undigested lactose continues on to the colon.
Lactase improves lactose digestion in people who have difficulty digesting it. Lactose isn’t limited to a glass of milk—it’s also found in sauces, gratins, pastries, certain deli meats, and many prepared foods, making it difficult to completely avoid on a daily basis. To understand and better manage lactose intolerance, diet remains the primary tool.
Take the capsule with a meal containing lactose: a simple, targeted dose that allows you to still enjoy cheese, yogurt, or a dairy-based dessert without making it an issue at every meal. It also provides flexibility in family meals when only one family member has trouble digesting lactose.
It’s especially useful for meals eaten away from home —whether at a restaurant, a dinner party, a business lunch, or while traveling—those times when you have no control over the recipes or the presence of milk, cream, or butter in the dishes. The capsule’s small size fits easily into a bag or pocket.
Cutting back on dairy products also means reducing one of the main dietary sources of calcium. For this reason, we recommend NHCO’s amino-chelated calcium: lactase breaks down milk sugar, while calcium compensates for the mineral intake lost by limiting these foods. Calcium is necessary for maintaining normal bone health.

Before taking your first capsule, the key question isn’t the dose but the nature of the problem. Many people who “can’t tolerate milk” have never distinguished between lactose intolerance and milk protein allergy: this is the most important precaution on the list, and should be read before anything else.
It’s not necessary to cut out all dairy products. Most people with lactose intolerance can digest small amounts without discomfort, particularly yogurt and aged cheeses, which are low in lactose. We recommend reserving the capsule for meals that are highest in milk and cream, and identifying which ones actually cause problems rather than taking it out of habit.
What does the “20,000 FCC” label on my box of Prescription Nature Lactase mean?
FCC is the unit of enzymatic activity defined by the Food Chemical Codex: it measures the enzyme’s ability to break down lactose, not its weight. This figure, rather than milligrams, is therefore used to compare two lactase supplements. With 20,000 FCC per capsule, Prescription Nature Lactase is significantly higher in potency than standard formulas, which are often dosed at around 4,500 FCC per serving.
Do I need to take Prescription Nature Lactase every day for 30 days, as a course of treatment?
No. Lactase acts only on the lactose in the meal it accompanies, and its effect does not accumulate from one day to the next: it does not stimulate the gut’s production of lactase. On days when you don’t eat a meal containing lactose, the capsule is therefore unnecessary. You should save the box for those specific meals, without following a set schedule.
How can I tell if I’m lactose intolerant before taking Prescription Nature Lactase?
Typical symptoms (bloating, gas, abdominal pain, diarrhea) usually appear between thirty minutes and two hours after eating a lactose-rich food. The diagnosis is made by a doctor, most often through a hydrogen breath test or by following an elimination diet followed by a supervised reintroduction.
Lactose is the main carbohydrate in milk. In babies, it provides a significant proportion of energy. In adults, it is mainly provided by milk and dairy products. To be digested, lactose must be hydrolysed by an enzyme called lactase, which some people lack in adulthood. Defects in this genetic programme in most of the world's population are often the cause…
