“- Why do I choose to take vitamin B complex? I've been working and used my brain a lot lately, so I supplemented with this. One pill is full of vitamins and various extracts that the body cannot produce on its own. This helps to nourish the brain directly, reduces the chances of getting Alzheimer's, makes you feel refreshed and reduces fatigue as well. - Another supplement that I chose is the Jelly Collagen. One sachet is a complete nourishment for my skin, wrinkles, bones, and joints. It's so delicious, like eating a snack. And it doesn't make you fat. One sachet is only 30 kal. and as you get older, you need to nourish yourself more.
