When packing, one thing that lots of people forget to pack are vitamins. Yet, as we travel, our bodies can be put into scenarios which would highly benefit from a good dose of vitamins.
It is while on holiday that we encounter so many germs in confined spaces like planes, buses and trains. It is then that we push ourselves to journey for more hours than we usually dedicate to a full work day to get to our destination. Not to mention that we often go from one type of weather to another. Then there are those of us who do no exercise at all while away on holiday, but instead go on marathon drinking sprees, and other forms of gluttony.
Yes, vitamins are not to be left at home, they should be with you in this time of need.
