Vitamin B5 also participates in the regulation of energy metabolism and reduces fatigue by having a positive effect on stress.

It is also involved in the synthesis of different steroid hormones, such as cortisol and adrenaline (which are the stress hormones), testosterone, estrogens and progesterone (which are the sex hormones).

In what foods can we find vitamin B5?

As its scientific name indicates (in Greek pantothen meaning everywhere), vitamin B5 is found in many foods , both of animal and plant origin, cooked and raw.

As it is water-soluble, it is preferable to cook foods with steam rather than with water, in order to limit the loss of the vitamin through dissolution in the cooking water. (Up to 40% of the original content) *.

It is present in:

  • Meat (duck, chicken): liver, kidneys
  • Eggs
  • Dairy products (gorgonzola)
  • Fish (trout and salmon).

  • Oilseeds (almonds, cashews, hazelnuts, macadamia nuts, walnuts, pistachio, avocado). Royal jelly also contains it.

* Note that all other water-soluble vitamins are also affected by this mechanism (if cooking in water, adding salt helps limit the osmosis mechanism and losses of the basic food).

Vitamin B5 is also heat-sensitive: avoid long cooking to preserve it
