Frequently Asked Questions

What are plant Sterols?

Plant sterols (also known as phytosterols) are natural substances that can lower your cholesterol. Plant steros are present naturally in small quantities in many fruits, vegtables, nuts, seeds, cereals, legumes, vegtable oils, and other plant sources. However, typical western diets supply only around 200-400mg plant sterols per day.

Are plant sterols a new solution to lowering cholesterol?

No. The cholesterol lowering potential of dietary plant sterols has been known for over 50 years, however according to new scientific research, a daily dietary intake of 1.6g free plant sterols up to a maximum daily intake of 3g “may reduce the risk of heart disease”. The well documented cholesterol – lowering effect of plant sterols is the basis for recommendations to include plant sterols into strategies to lower LDL(bad) cholesterol.

What is the source of plant sterols in Zerochol?

Soybean oil, sunflower oil, maize, rapeseed oil and tall pine tree oil.

Allergen Information

Contains soy oil – no soy protein present.

Zerochol is dairy free, nut and gluten free.

Can you take Zerochol® with cholesterol lowering medication

Yes, One of the advantages of taking Zerochol® alongside cholesterol lowering medication is that it has been shown that cholesterol lowering medication plus plant sterols work more effectively than doubling the dose of the statin 3. If a person is on statins, you can recommend that they introduce Zerochol® to their program. When they return to see their GP, the impact of using Zerochol® will be evident and therefore the GP may look to reduce the medication dose.

Please inform you GP if you are using Zerochol as a cholesterol lowering supplement.

What about soy oil and isoflavones?

Isoflavones, which have a “weak oestrogenic effect”, are present in all soy foods with the exception of soy sauce and soy oil, therefore Zerochol® plant sterol tablets which contain soy oil are perfectly safe as they contain no isoflavones.

Is Zerochol® a natural product?

Yes, Zerochol® contains 100% natural plant sterols (800mg plant sterols/ tablet)

Does Zerochol® affect CoQ-10 synthesis?

No, plant sterols do not affect the synthesis of CoQ-10. Plant sterols are structurally similar to cholesterol and block the absorption of cholesterol from foods, The body takes up less cholesterol and reacts by increasing self controlled synthesis. It cannot however completely compensate for the inhibition of absorption which means that the cholesterol level falls. The only side effect to plant sterols is that they can interfere with the absorption of carotenoids, namely beta-carotene but this can be compensated for in the diet by increasing fruits and vegetables in the diet.
