This observation enabled them to develop a rapid chemical and bioassay to isolate the factor from egg white in [ chronology citation needed ] , they called it Ovoflavin.

The same group then isolated the same preparation a growth-promoting compound with yellow-green fluorescence from whey using the same procedure lactoflavin. The name "riboflavin" often abbreviated to Rbf or RBF [44] [45] comes from " ribose " the sugar whose reduced form, ribitol , forms part of its structure and " flavin ", the ring-moiety which imparts the yellow color to the oxidized molecule from Latin flavus , "yellow".

The reduced form, which occurs in metabolism along with the oxidized form, is colorless. From Wikipedia, the free encyclopedia. A No risk in human studies and C [1]. This section needs additional citations for verification. Please help improve this article by adding citations to reliable sources.

However, there is a paucity of research considering the role that MCTs may play in inducing ketosis more rapidly in a ketogenic diet with a 4: Therefore, it is likely that the use of MCTs, resulting in ketonaemia and ketogenesis, could reduce time to NK and symptoms of keto-induction.

These symptoms are likely to relate at least in part to the transition from a glucose dominant fuel system to one in which BOHB becomes a primary fuel source. Likewise, mitigation of symptoms of keto-induction is likely to result in improved adherence to the diet.

The aim of the present study, therefore, was to investigate, in a randomised, double-blind, placebo-controlled trial, whether MCTs reduce time to nutritional ketosis and symptoms of keto-induction and mood in a classic ketogenic diet. The primary outcome measured was the time taken to achieve NK. Secondary outcomes were symptoms and mood.

Twenty-eight participants 2 males, 26 females: The study took place between the 2nd and 21st of November Participants were prescribed a ketogenic diet with a 4: Minor differences in carbohydrate and protein were due to the use of a protein intake of 1.

While MCTs are essentially nontoxic [ 40 ], Ivy et al. The Profile of Mood States is a questionnaire commonly used to determine the overall mood state of study participants [ 42 ].

Saya Shacham developed a shortened, 37 question version of this form with correlation coefficients between the short and original scales all above 95 indicating the suitability of this shortened form for estimating mood. The symptoms questionnaire was developed by one of the authors d C. Harvey based on symptoms commonly observed in previous studies of ketogenic diets. The primary researcher was unblinded to the supplement-oil key only after data analysis had been completed.

Participants were instructed to contact the primary and tertiary researchers for any assistance during the study duration. The research was conducted in accordance with AUT ethical guidelines. Pairwise comparisons were made between each of the 19 time points for control LCT and experimental MCT trials for all using a customised analysis spreadsheet [ 43 ].

Pairwise comparisons were also made between observed measures relative to respective baseline values for each group. Data for BOHB and BG comparisons were log transformed for analysis to reduce bias arising from nonuniformity of error and subsequently back transformed to obtain changes in means and variations as factors.

An effect was deemed to be unclear if its confidence interval overlapped the thresholds for substantiveness, that is, if the effect could be substantially positive and negative [ 45 ]. The smallest worthwhile change for between-group means for all blood and perceptual measures was calculated as 0.

Inferences were based on threshold chances of harm of a difference between groups of 0. A total of five participants withdrew during the data collection period—two from the MCT group illness and gastrointestinal discomfort and three from the LCT group one due to extreme hunger, one unreported, and a third due to light-headedness and inability to concentrate. Mean imputation analysis was used to adjust for the missing measures [ 48 ]. While clinically trivial effects were observed for days one to six, between-group effects for days seven to 19 were clear for MCT relative to LCT Table 2.

The magnitude of these effects was 0. There was also a very likely negative effect of BOHB on glucose in both groups. That is, higher BOHB levels resulted in lower glucose levels. Overall, time to ketosis was more rapid with MCT supplementation. Supplementation with MCT versus control resulted in lower symptoms associated with keto-induction, with the mean sum of symptom scores lower in the MCT group across all time points except for days 16, 18, and 19 Figure 4. Effects of MCT on the change in symptoms from baseline were possibly beneficial for days 4, 6, 9 to 11, and 13 to 15, but on all other days, effects were unclear relative to LCT.

Improvements in symptom scores from the preceding day indicated a possibly beneficial effect of MCT on 11 of 19 days. Mood scores were improved at all time points from baseline in both groups with generally better mood reported by the LCT group compared to the MCT. As BOHB levels increased, reported mood improved in both groups.

When considering changes relative to the preceding day, there were approximately equal days of improvement in MCT versus LCT supplementation nine and ten days, resp. A possible beneficial effect was observed across eight days for MCT supplementation Table 2. There was a possibly beneficial effect from MCT supplementation when glucose was used as a predictor of mood. This study was the first to assess the impact of MCT on time to NK and symptoms of keto-induction and mood and, we believe, the first to specifically describe symptoms of keto-induction keto-flu , within the first few days of a ketogenic diet.

MCTs are demonstrably ketogenic [ 29 — 31 ], and this effect was expected. We would consider an effect of MCT on time to NK to be likely due to the demonstrable effect on ketogenesis and ketonaemia resulting from MCT ingestion [ 29 — 31 ]. Studies with larger numbers of participants will be required to test this hypothesis adequately. Symptoms initially worsened in response to both diet interventions, but these were ameliorated by day four for MCT and day five for LCT.

At this time point, mean BOHB levels were 0. We also considered that a higher entry point to NK could be 0. With this hypothetical higher threshold for NK, achievement of NK was greater in the MCT group for the first three days, but this result was also not significant, nor was the achievement of NK appreciably different after this time.

Further exploration to define NK more appropriately to functional outcomes and to determine evidence-based thresholds is warranted. A possibly beneficial clinical effect was exhibited on symptoms by MCT application across almost all time points, and mean symptom scores returned to baseline a day earlier with MCT supplementation. This result further suggests that there might be a threshold level of BOHB required to mitigate some of the symptoms associated with keto-induction and that the higher BOHB exhibited in the MCT group may have caused this reduction in symptoms.

This is a result that warrants further exploration. Relative to LCT, there was a 1. There are known gastrointestinal effects from ingestion of MCTs [ 41 ], and in the amounts provided to participants, it is possible that symptoms noted with a higher incidence in the MCT group, especially diarrhoea and stomach pain, resulted from the use of MCTs.

Reduced dosages of MCTs warrant further study to determine dose-dependent effects on symptoms and mood relative to control. Mood scores correlated with symptom scores, but effects of MCT on mood state were unclear.

It is unlikely that MCT would worsen mood independently, except if resultant adverse effects such as the stomach pain noted above was sufficient to depress mood. There were several limitations to this study. Differences in compliance may have resulted from the free-living nature of this study.

We did not adjust for exercise and activity, although participants were advised to not change their current exercise habits. Standardised diets both for male and female were provided per age- and gender-adjusted average requirements.
