Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The allocated product is to be taken in the morning orally with plain water. Participants will supplement daily for 8-weeks. FerminGIN is composed of fermented red ginseng extract (90%) and gamma-cyclodextrin (10%). Participants will take a daily dose of 700 mg (2 x 350 mg capsules), which includes 600 mg of FermenGIN and 100 mg of excipients.

If participants meet the inclusion criteria, they will be given a full explanation of the study requirements (PICF) and asked to complete the electronic consent form and enrolled into the study for 8-weeks. Enrolled participants will then be randomized (1:1) into one of two groups: FRG or placebo. Participants will then have baseline measures prior to starting product.

Following enrolment and while at the clinic, participants will complete the baseline measures. These include: questionnaires and a fasted blood test so that we can measure a range of other markers in the blood. At the end of the initial clinic visit participants will be given a referral to attend an external site (eg. QScan) to have an ultrasound of the right leg artery to assess blood flow. This scan is to be completed within 72 hours of the initial clinic appointment and prior to any trial supplement being consumed.

Following baseline data collection (including the leg ultrasound), participants will undertake 8-weeks of supplementation. During this period, participants will have a fasted blood sample and protocol monitoring measures taken at the midway point (4-weeks). During the week-4 visit, the final referral for a leg ultrasound will be provided to the participant. This is to be completed within the 8th week of the supplementation period and no later than 24 hours after finishing their final trial product dose. At the completion of the trial (week 8) participants will return to the study clinic and repeat the full baseline measures.

Throughout the 8-week trial, participants will complete exercise and food frequency recall at each clinic visit to monitor possible variables that could change cardiac function. Any product remaining at the conclusion of the study is to be disposed of.

Adherence will be monitored by capsule return at the end of the intervention period (8 weeks).

b) Examples of acceptable forms of highly effective contraception include:
• Established use of oral, injected or implanted hormonal methods of contraception.
• Placement of an intrauterine device (IUD) or intrauterine system (IUS).
• Sterilised male partner (with the appropriate post-vasectomy documentation of the absence of sperm in the ejaculate).
• True abstinence: When this is in line with your preferred and usual lifestyle

c) Examples of non-acceptable methods of contraception include:
• Condoms alone or double barrier
• Periodic abstinence (e.g. calendar, ovulation, symptothermal, post ovulation)
• Withdrawal
• Spermicide (as it is not approved as a method of contraception in Australia)

It is the responsibility of the participant to ensure that prior to and during the trial, that if they intend to try to conceive, change birth control or if there is any chance they suspect they are pregnant, they notify the trial investigators immediately.
