Vegans May Need Lysine Supplements
I started taking a lysine supplement to prevent cold sores and accidentally discovered that it's something really important for a vegan diet.
While plants are a source of lysine and some even have a lot, on a strict vegan diet you may end up not getting enough, like I did. Especially if you're very physically active.
There were no overt symptoms. Just general tiredness and fatigue.
A lysine supplement really made a difference in my overall alertness and physical ability. I stopped sleeping so long and stopped waking up tired.
If you're sure your vegan diet is healthy and well rounded and don't understand what's missing, lysine may be the answer.
It's an essential amino acid found in many animal products. So taking a supplement isn't generally dangerous. You can take in a lot without any negative impact. So it's definitely worth a shot if you're experiencing unexplained fatigue.
