Why Do We Need Vitamins?

Vitamin A, B, C, D, E, F, G, H, I….we get it, there’s nearly a full alphabet of vitamins, but why do we actually need them? From the day dot, we’re told to eat our 5 a day to make sure we get enough of these little gems. You can find them everywhere; in pills, powders and everything in between, containing vitamin this and vitamin that. You’ve probably even seen your grandparents popping a few in the morning (well we hope those are vitamins anyway).

Vitamins are actually considered essential. Basically, you and I wouldn’t be here without them. You can find vitamins in loads of different foods, including fruit, vegetables, fish and meat.

But vitamin supplementation in itself is pretty popular in the fitness community. The reason being – we can pack in pretty much every vitamin you would need into a pill. Saving you time, money and of course those dreaded extra calories.

It goes without saying, you can consume the correct amount of vitamins through your food, but it’s extra important to make sure you keep your levels as high as possible especially if you take part in any physical activity. Plus, you’d have to eat a heap load to make sure you got every last one. These convenient capsules have you covered.

Essential Vitamins

Vitamins are extremely important even if you don’t take part in exercise. There are 13 essential vitamins necessary for proper bodily functions like metabolism, building bones, teeth, tissue and even blood, so basically everything. All hail the might vitamins! Unfortunately, as amazing as our bodies are they cant actually produce these vitamins themselves (Fairfield & Fletcher, 2002), other than vitamin D and vitamin K. BOO! But don’t worry, like we’ve talked about they can easily be consumed through food and supplementation.

There are two types of vitamins that we need to consume, water-soluble and fat-soluble. These two sound pretty straight forward and self-explanatory, and well they are a little, but just keep reading and you’ll find out what these mean. So, water-soluble vitamins such as B and C vitamins (Kennedy & Haskell, 2011) are quickly eliminated through our urine, so we must consume these daily to replenish what is lost. Whereas, fat-soluble vitamins take a piggyback ride on the fat we consume to be transported around the body, resulting in them being stored for a limited time in our fat tissue. That little muffin top has some uses. This means that these vitamins are stored longer than the water-soluble vitamins meaning that daily consumption is not necessary (Fairfield & Fletcher, 2002).

Vitamins are a jack of all trade for overall health, but to be specific they all individually have their own benefits for key areas of the body. See below for the Vitamin A-Z list to cast your eyes over. Please bear in mind that these are as a collective. For example, there are 5 different types of B vitamins.

Why supplement Iron?

Iron helps red blood cells carry oxygen to your muscles. Oxygen transportation is critical for energy production. It’s one of the reasons why when we take part in exercise we get out of breath. It’s our body needing extra oxygen to produce energy so our muscles can contract and move. Research has indicated that regular endurance exercise leads to greater iron loss (Hinton, 2014). To combat this loss the Food and Nutrition board suggests a 30% increase in iron for those who exercise on the regular.
