Interventional
Description of intervention(s) / exposure
This is a double blinded, randomised, placebo controlled, cross-over trial
This trial will involve 30 healthy participants who will be randomised to two treatment groups, each group consisting of 15 participants. In the first group, the 15 participants will take the nutrient supplement (Lester's Oil) or placebo for 4 weeks. Each nutrient capsule is made up mainly of six ingredients: vitamin D:25-OH (500IU), long chain PUFA-Omega-3 from fish oil [more than 500mg] as well as CoQ10 (50mg), zeaxanthin (0.82mg), lutein (3mg) and astaxanthin (500mcg). Each nutrient capsule also contains natural mixed tocopherols, vitamin E with ascorbyl palmitate (1mg) and is enclosed in a soft gel composed of gelatin, glycerine soft gel, beeswax and natural annatto. This will follow with a 4 week period of no supplementation and then another four week period of taking a similarly encapsulated ‘medium-chain tryglyceride oil’ placebo. The placebo was a Medium Chain triglyceride oil – [MCT- 8+10 Triglyceride] (MCT). Its major components were FAD - C6:0 Caproic 0.0 2.0%; FAD - C8:0 Caprylic 50.0 -80.0 %; FAD - C10:0 Capric 20.0 -50.0 %; FAD - C12:0 Lauric 0.03.0 %.
Two capsules of the nutrient supplement or placebo were taken daily, (orally), with the participants lunch or dinner meal

The second group will take the encapsulated ‘medium-chained oil’ placebo for the first four weeks, followed by a four week period of no supplementation. The nutrient supplement will then be taken for the remaining four weeks,

All participants are blinded to the treatment regime they are on.

The levels of CoQ10 were determined in serum for each trial participant at each collection point as a measure of dietary uptake and compliance in the study. Participants were also asked to return their containers of left over capsules (more capsules than needed by the study were given) and these were counted as another indicator of compliance.

The number of participants selected for this trial was based on the Jorgensen’s et al. ‘Vitamin D3 treatment in Crohn’s disease–a randomized double-blind placebo-controlled study’ (Jorgensen SP, Agnholt J, Glerup H, Lyhne S, Villadsen GE, Hvas CL, et al. Clinical trial: vitamin D3 treatment in Crohn’s disease–a randomized double-blind placebo-controlled study. Aliment Pharmacol Ther. 2010;32(3):377-83) .This data indicates that the difference in the response of matched pairs is normally distributed with standard deviation 4. If the true difference in the mean response of matched pairs is 27 we will be able to reject the null hypothesis that this response difference is zero with probability (power) 1.000. The Type I error probability associated with this test of this null hypothesis is 0.05. Based on these prior data, the proposed numbers are appropriate to detect a true difference in the key outcome measure (vitamin D level).
