Plain English Summary
Background and study aims
Menopause is an important stage in a woman’s life, in which they stop having periods and are no longer able to get pregnant naturally. Following the menopause, women have a higher risk of developing long-term health conditions such as osteoporosis (weak bones), cardiovascular disease (disease of the heart and blood vessels), and dementia, as the hormone changes following menopause cause changes in the body. Nutritional supplements can help older women to stay healthy and energetic, as they provide important nutrients that the body is lacking. Honey and other hive products such as royal jelly, propolis, bee pollen, bee bread and bee could have been reported to contain substances that are nutritious and have been used to treat a range of conditions. So far, studies looking at the effects of honey in menopausal women are limited. Animal studies have shown that Tualang honey (a Malaysian jungle honey) can help to regulate hormones and improve health of the female reproductive system in mice, as well as restoring bone density in rats. Other products such as bee bread and royal jelly contain higher mineral, free fatty acids, protein and essential amino acids compared to honey. Therefore, the combination of bee hive product called Honey Cocktail is expected to be more effective than honey alone. The aim of this study is to investigate the health benefits of Tualang honey compared to Honey Cocktail in menopausal women.
Who can participate?
Healthy women aged 45 to 65 years old who have been menopausal for more than five years.
What does the study involve?
Participants are randomly allocated to one of two groups. At the start of the study, all participants attend a study visit at which they complete a questionnaire, have scans to measure their pelvic health and bone density, and have blood samples taken. Those in the first group are then asked to consume one 20g sachet of Tualang honey every morning for 12 months. Those in the second group are asked to consume one 20g sachet of Honey Cocktail every morning for 12 months. During the 12 months of the study, participants are asked to come to the study centre every three months for a check-up and to be interviewed about any side effects they have experienced. After 12 months, participants repeat the initial measures taken before treatment began in order to find out if there have been any changes to their cardiovascular (heart and blood vessels) health, hormone levels, bone density and psychosexual health (mental and emotional attitudes to sex).
What are the possible benefits and risks of participating?
Participants benefit from having expenses relating to their participation paid during the study. There are no notable risks involved with participating.

Intervention
Participants are randomised based on the randomization blocks of four and will be assigned to either receive Tualang honey or Honey Cocktail base on a randomization table which was computer generated. Participants will only identified based on their identification number and will be allocated to the study treatment as they are recruited.
Tualang honey group: Participants will receive one 20g sachet of Tualang honey every morning for 12 months.
Honey Cocktail group: Participants will receive one 20g sachet of Honey Cocktail every morning for 12 months.
The study participants are advised to come at 3 monthly intervals at CTU for the next 12 months at which they are interviewed about compliance and side effects experienced and examined by the clinicians involved in the trial. At 12 months, participants attend a follow up appointment at which questionnaires are undertaken, blood samples are taken, bone density is measured, and a pelvic ultrasound is completed.

Primary outcome measure
1. Blood pressure is measured by an automatic blood pressure monitor at baseline and 12 months
2. Fasting lipid profile is measured by analysing blood samples using an automated lipid analyser at baseline and 12 months
3. Follicle stimulating hormone, luteinizing hormone, testosterone levels and estradiol levels are measured by analysing blood samples using an automated hormone analyser at baseline and 12 months
4. Bone density is measured using a mini bone ultrasound device at baseline and 12 months
5. Oxidative stress is measured by analysing blood samples at baseline and 12 months
Secondary outcome measures
1. Psychosexual changes are measured using the Validated Malay version of Women's Health Questionnaire and the Validated Malay version of Female Sexual Function Index at baseline and 12 months
2. Adverse events are measured through interviews and examinations by the clinician in charge of the trial and the completiong of an Adverse Events Form at 6 months and 12 months
3. Serious adverse event rate is measured by calculating the incidence of death, in-patient hospitalization, malignancy, and/or result of an overdose within 6 months and 12 months
4. Pelvic pathology is assessed using pelvic ultrasound at baseline and 12 months
5. Liver and renal function is measured using kidney and liver function tests on blood samples at baseline and 12 months
