Plant sterols naturally occur in small quantities in vegetable oils, nuts, seeds, grains, fruit, and vegetables. You can also find them (in greater concentrations) in Flora ProActiv products, to which these helpful substances are added. In more than 50 clinical studies, plant sterols have been proven to significantly lower cholesterol*.

What foods are high in plant sterols?

As mentioned above, plant sterols occur naturally in plant-based foods, but only in small amounts. The simplest way to eat enough plant sterols in food to help lower cholesterol is to enjoy products to which they have been added: Flora ProActiv products contain the recommended daily amount of plant sterols to achieve this.

How do plant sterols work?

Plant sterols (as found in Flora ProActiv foods) work by reducing the absorption of some cholesterol from the gut. This reduces the amount of cholesterol that enters the bloodstream, resulting in lower levels of LDL (bad) cholesterol.

How do plat sterols work

Eating the recommended amount of plant sterols (between 1.7-2.4 grams) daily can help you lower your cholesterol levels by 7 to 10% in just two to three weeks*.

Plant sterols and cholesterol: do plant sterols lower cholesterol?

To gain the most benefit from plant sterols in foods, you need to eat between 1.7 and 2.4 grams every day as part of a balanced diet with sufficient fruit and vegetables. With three servings of Flora ProActiv spread or milk (or just one mini drink) every day, you can be sure you’re getting the recommended amount of plant sterols*. 

What’s the amount of plant sterols in one serving of Flora ProActiv?

Serving proactiv

  • One serving of Flora ProActiv spread is 10g – that’s about 2 teaspoons, or enough for 1–2 slices of toast. Or you could try it as a topping to your jacket potato, in sandwiches, or melted over veg.
  • A serving of Flora ProActiv milk drink is 250ml – that’s a quarter of a carton or a medium-sized glass. It’s delicious poured over cereal or added to tea and coffee over the course of the day.
  • One Flora ProActiv mini drink contains your plant sterols for the whole day! These come in four tasty flavours: Strawberry and Original

Can I take plant sterols as well as statins?

If you are on statins, plant sterols can offer additional benefits in lowering cholesterol*. In fact, because each approach lowers cholesterol in a different way, the combined effect is cumulative. For advice on combining cholesterol-lowering medications and Flora ProActiv, please speak to your GP.

Plant sterols: side effects

However, plant sterols may not be nutritionally appropriate for pregnant and breastfeeding women or children under five. When you decide to lower your cholesterol, you should always ask your GP for advice – including on any dietary changes.
