do you feel low of have depression 5-HTP

5-HTP 
What is it?
Tryptophan is an amino acid found in meat, peanuts and sesame seeds. The brain converts tryptophan into 5-HTP - a variation of tryptophan - which is then turned into serotonin, one of the 'happy' chemicals that helps control our appetite, mood and sleep patterns.
How does it work?
Tryptophan is absorbed into the brain more easily when there is also carbohydrate present. When we are feeling depressed we tend to crave starchy foods in an unconscious effort to absorb more tryptophan, boosting our serotonin levels.
Taking 5-HTP as a supplement can boost our serotonin levels naturally so you avoid the food cravings and hopefully avoid putting on weight.and get weight loss personal trainer london 
Has it been proven?
A study published in the American Journal of Clinical Nutrition found that obese patients taking 5-HTP had significantly greater weight loss than a control group who were not taking the supplement. Their carbohydrate intake was also reduced, but this may have been
because they were following a diet for part of the study.
Although the study was successful, it may be difficult to re-create the results for yourself. 'The study may have used 'drug like' levels of 5-HTP which cannot be bought over the counter,' says Lyndel Costain.
Where can I get it?
5-HTP is available in larger high-street chemists and good health food shops. If you think you are suffering from depression, talk to your GP who can help you treat the condition.
PYRUVATE
What is it?
Pyruvate is a natural compound produced by the body that helps with metabolism. It is used to help convert sugar in the blood into glycogen, the fuel that muscles use during exercise.
How does it work?
The theory is that taking extra pyruvate will stimulate your metabolism which can help you lose weight. Although pyruvate is involved in energy production, experts are still unsure exactly how it works.
Has it been proven?
The University of Pittsburgh conducted a study ten years ago that found taking large doses of pyruvate could reduce body fat without the need to do any exercise.
Another study following obese women taking up to 100g of pyruvate every day also found they lost weight and put less weight back on when they stopped dieting.
However, these studies have been heavily criticised. Experts are concerned about the high doses of pyruvate being taken as they could have an effect on the balance of minerals and salts in the body, leading to stomach upsets and nausea.
Lyndel Costain, consultant nutritionist for the Medical Research Council, says, 'Pyruvate may be effective at high doses but there is little information to explain whether it has the same effect at lower doses.'
Brigid McKevith from the British Nutrition Foundation adds, 'More studies are needed to firmly establish any positive effect of taking pyruvate on weight loss in humans.'
Where can I get it?
Pyruvate supplements are available in health food shops, but check the level of pyruvate contained to avoid triggering a stomach upset. If you are worried, ask your doctor or a nutritionist for more advice.
