The aim of this study is to evaluate the safety and tolerance of Turmipure Gold™ product during a chronic consumption of 5 weeks in healthy subjects. The hypothesis of this study is that there are no alterations of the gastrointestinal tolerance, of the haematological and biochemical profiles due to Turmipure Gold™ consumption compared to placebo.

Primary | composite score of gastrointestinal tolerance | The primary endpoint in this study is the composite score of gastrointestinal tolerance (Bristol stool chart and Lickert scale) after 5 weeks of supplementation +/- 3 days (a.u./day, range 0-50), expressed in a.u
This composite score will be defined as the sum of the ratings of GI symptoms scores and the composite score of stool frequency and consistency (36): Composite GI symptoms tolerance = Bloating score + Abdominal cramping score + Stomach noises score + Flatulence score + Stool score* |
5 weeks +/- 3 days (V2) | |
Secondary | Individual gastrointestinal symptoms (Bristol Stool Chart) | Bristol Stool chart is used - this scale allows to measure to evaluate stool frequency and consistency. The Bristol Stool Chart or Bristol Stool Scale is a medical aid designed to classify faeces into seven groups. The Bristol Stool Chart shows seven categories of stool:
Type 1-2 indicate constipation Type 3-4 are ideal stools as they are easier to pass, and Type 5-7 may indicate diarrhoea and urgency. |

Secondary | Individual gastrointestinal symptoms (Lickert scale) | Lickert scale was used to evaluate gastro-intestinal symptoms. The gastro-intestinal symptoms will be reported during 3 days before V1 visit. A mean of these 3 days will be calculated. Each GI symptom will be given a score of 0 (no symptoms) to 10 (severe symptoms).
This scale allow to have four scores : Bloating score (a.u./day, range 0-10), Abdominal cramping score (a.u./day, range 0-10), Stomach noises score (= Borborygmi) (a.u./day, range 0-10), Flatulence score (a.u./day, range 0-10), These scores will be combined to evaluate the gestointestinal symptoms |

Secondary | quality of life score | The GastoIntestinal quality of Life (GIQLI) questionnaire is composed of 36 items. The responses for each item are scored from 0 to 4, from the worst to the best rating. Example of answers to question 1: always (0), most of the time (1), sometimes (2), rarely (3), never (4).
The average overall score for each subject and visit will be calculated by summing the scores of each question divided by 144 and multiplied by 100 (average overall score reduced to a score between 0 and 100; the maximum score being 100) (Slim et al., 1999). The items focus on 5 subscales (Slim et al., 1999): Symptoms (19 items): items 1 to 9 and 27 to 36 (theoretical score range: 0-76), Fitness (7 items): items 15 to 21 (theoretical score range : 0-28), Emotions (5 items): items 10 to 14 (theoretical score range: 0-20), Social integration (4 items): items 22, 23, 25 and 26 (theoretical scope range: 0-16), The effect of possible medical treatment (1 item): item 24 (theoretical score range: 0-4). |

Secondary | 3 days Food diary | This diary will be filled by subjects the week before V1 visit and the data will be collected and analyzed by a dietician.
This diary will allow to evaluate food intake : total energy intake (kcal), percentage of energy intake from proteins (%), percentage of energy intake from fat (%), percentage of energy intake from carbohydrates (%), dietary fiber (g) and hydric intake, These data will be combined to evaluate the food intake |

Secondary | Physical activity global score | This self-administered questionnaire IPAQ will be filled by subjects at V1 visit. For each subject and visit, the total metabolic equivalent will be calculated from the IPAQ questionnaire short form.
This continuous score, expressed as MET-min per week (MET level x Number of minutes of activity/day x Number of days per week), will be calculated using the following formula (Guideline IPAQ, 2005): Total MET-minutes/week = Walking (METs*min*days) + Moderate intensity (METs*min*days) + Vigorous intensity (METs*min*days) with: . Walking = 3.3 METs; Moderate Intensity = 4.0 METs; Vigorous Intensity = 8.0 METs. |
