The aim of LipiDown (Hawthorn + Phytosterol) clinical trial is to test the blood lipids reduction effect of plant sterols and hawthorn in milk powder in a pilot human trial: demonstrate potential to reduce total blood cholesterol more than 10% and/or total triglycerides more than 15%, as required by State food and drug administration (SFDA) regulation.

The proposed clinical trial is a pilot randomized, double-blind, placebo controlled, parallel, multicenter study with three treatment groups.

The total number of 75 subjects should be enrolled to provide for a 20% dropout rate.

Subjects will be randomized into one of the following 3 groups:

• milk without sterols and hawthorn powder
• milk with 1.2g/d sterols and 8g/d hawthorn powder
• milk with 1.8g/d sterols and 8g/d hawthorn powder

The trial population will consist of female or male volunteers aged 18 - 65 years of age with primary mild to moderate hyperlipidemia documented by a serum cholesterol of 5.18-6.21mmol/L AND serum Triglycerides (TG): 1.7-5.65mmol/L , for at least 1 time tested by central laboratory in the past 2 weeks prior to recruitment.

Inclusion Criteria:

• Chinese male or female 18 to 65 years old (inclusive). Fasting Serum TC: 5.18-6.21mmol/L (equals to 200-241 mg/dl) AND Serum TG: 1.7-5.65mmol/L (equals to 150- 500 mg/dl) for at least 1 time tested by central laboratory in the past 2 weeks prior to recruitment.
• Primary dyslipidemia.
• The subject demonstrates an understanding of the given information and ability to record the requested data.
• Having obtained his/her informed consent
