The importance of antioxidants for gametes and embryos

"Although oxygen is used in the creation of ATP (the currency of energy in our cells), during this process Reactive Oxygen Species (ROS) are also created. Herein lies the problem; while low levels of specific ROS are involved in cell signalling pathways, at higher concentrations ROS (also refered to as oxidative stress) become toxic to cells quickly, and have a well-documented negative effect on sperm, eggs and embryos.

When ROS build up they are highly destructive and damage our DNA, our cell membranes and the organelles within our cells – especially our mitochondria, which are the “Power Plants” of our cells. 

Antioxidants protects from damaging effects of Reactive Oxygen Species

Fortunately for you and I, our bodies possess a rather sophisticated system for dealing with excess ROS in the form of antioxidants (either produced by the body itself or obtained directly in our diet), which in essence help to neutralise the damaging effects of ROS.

Antioxidants come in many forms, and we need to ensure we consume sufficient amounts of antioxidants such as vitamin C (ascorbic acid), A (retinol) and E (α-tocopherol), in order to maintain a healthy body. Indeed, data is emerging that a diet high in antioxidants confers some protection against neurological conditions, such as Alzheimer’s and Parkinson’s disease, which typically are associated with some form of mitochondrial pathologies, possibly due to increased oxidative stress.

So to ensure your future cognitive function, the message instilled is to remember to consume plenty of carrots (beta-carotene), green vegetables such as spinach (vitamin E), a variety of fruits and berries (vitamin C, E…), as well as dairy products and liver (vitamin C). In other words, eat a well-balanced diet!..."
