Vitamin B12 Absorption Study

This randomized, double-blind, crossover trial (Phase IV) aims to compare the absorption of a novel permeability-enhanced oral vitamin B12 formulation (Ampli-B) versus standard oral vitamin B12 in 12 healthy adults aged 50 years and older. Each participant receives a single dose of each formulation in randomized sequence, separated by a minimum 10-day washout. The primary outcome is time to peak serum concentration (Tmax) of total and active vitamin B12 (holotranscobalamin). Secondary outcomes include Cmax and AUC parameters.

Gut Microbiome and Metabolic Health Study

The goal of this clinical trial is to assess whether TRPTI (oleoylethanolamide) can reduce plasma imidazole propionate levels and improve insulin sensitivity and metabolic health in healthy adults aged 18 years and above with BMI 18.5-29.9 kg/m². The main question it aims to answer is does TRPTI reduce plasma imidazole propionate (a gut microbiota-derived metabolite linked to insulin resistance)? Researchers will compare TRPTI 300 mg to placebo in a parallel design to see if TRPTI reduces imidazole propionate levels and improves metabolic health markers compared to placebo. Participants will: * Take 2 capsules of their assigned study product daily for 8 consecutive weeks * Attend 3 clinic visits (at baseline, week 4 and week 8)

Sleep and Stress Study

The goal of this clinical trial is to learn if natural supplements (lavender oil, PEA, and OEA) work to improve sleep and reduce stress in adults with moderate stress levels and sleep difficulties. It will also learn about the safety of these natural supplements. The main questions it aims to answer are: * Do these supplements improve sleep quality? * Do they reduce perceived stress levels? * Do they reduce anxiety symptoms? * What medical problems do participants have when taking these supplements? Researchers will compare three active treatment groups (lavender oil, PEA, Trpti which contains OEA) to a placebo (a look-alike capsule that contains no active ingredients) to see if these natural supplements work to improve sleep and reduce stress. Participants will take 1 capsule (either active supplement or placebo) every day for 8 weeks and attend 2 clinic visits with a phone check in in between.

Long-Term PEA Safety Study

The goal of this clinical trial is to learn about the long term safety of PEA supplementation in healthy adults. This clinical trial will be in both males and females who are 18 years or older and are healthy volunteers. The main aim of the study is to assess the safety of long-term use of PEA by assessing the difference between the two groups for serious adverse events, non-serious adverse events, vital signs and biochemistry following 12 months of PEA supplementation. Participants will: * Have their suitability for the study checked against the full inclusion/exclusion criteria during the screening process. * Eligible participants will then complete a baseline visit where assessments will be performed and the participant will be randomly assigned to receive the study product or a placebo. Participants will then consume their assigned study product every day for 12 months. Participants will not know what product they have been assigned during the study. * Following the baseline visit, there will be 4 visits over 12 months. On months where participants do not have a visit there will be a check in phone call. * During visits there will be safety assessments performed, blood sampling and questionnaires. The trial will include two participation modes: 1. In-clinic participation (Brisbane): Participants will attend all visits in-person at the RDC Clinical facility. 2. Remote participation for participants outside of Brisbane: A subgroup of up to 120 participants will participate remotely with virtual visits and at-home assessments. Participants will attend their local pathology centre for blood sampling.
