Enough has already been said about vitamin C, so I refer the reader to the section on vitamins. This discussion has also been accompanied by another on the antioxidant function of this vitamin specifically. As for phosphatidylserine, this is a particular type of lipid consisting of two fatty acids linked to a molecule of glycerol (mentioned at the beginning of the chapter) and one of ethanolamine phosphate. It is particularly represented in the central nervous system and its main role is related to apoptosis (controlled, physiological cell death).
Function
The hormone cortisol, ‘the stress hormone’, has already been discussed above. We have seen that cortisol production increases when physical load is applied. Now, although a slight increase in cortisol during exertion is physiological and, in some circumstances, even desirable, excessive secretion of this hormone can lead to muscle catabolism. In this respect, there is evidence that phosphatidylserine and vitamin C can reduce cortisol production during exercise.
Negative notes
With regard to vitamin C, please refer to the section on antioxidant supplements with a slimming function. Regarding phosphatidylserine, on the other hand, there are no known adverse effects associated with supplementation with this substance.
Form and dosage
The indications for vitamin C are the same as those given in the section on antioxidants for slimming. As for phosphatidylserine, it is mostly available on the market in tablet form, but soluble powder products are also available. It is recommended to follow the dosage indications on the label.
