Vitamin D is Not a Vitamin!?!

Posted on August 13, 2015 by Origin Athletics

Sun makes you super, man.

If you're like me (after reading the past few days of the blog, you know you're not), you feel like home is where the sun is. Aside from my imaginative writing topics, I'm a pretty mellow dude. The rain doesn't completely defeat my happiness, but murky skies can take their toll. The winter months can be dreary in Vancouver, but it really does drive our appreciation for sunny skies.

Vitamin Sun (also known as D) has definitely gotten its fair share of attention in the supplement world. It helps your body absorb calcium, and the two of them work together in creating strong healthy bones and teeth (even tiny little ones like mine). It also helps in maintaining healthy function in your muscles, nerves, and immune system. When D is low, your reaction time can be reduced as well as your stamina to carry your through the day. A drop in your immune system can explain your susceptibility to disease or sickness. The singular or combo affect of these can directly dictate your mood.

Even in the cold you can appreciate a brisk sunny walk through the city. Your body can make D from sunlight. You can see and feel the improvement in mood and function after your exposure to sunlight. When you goop on layers of sunscreen, it may protect you from harmful rays of sun, but it will inhibit the manufacture of D in the body. So make sure you get a good dose here and there with bare exposure. Use your brain.

The balance of vitamins and minerals in the body is important. You are lying to yourself if you think you get enough D in this city. To say all your lunches, and dinners pack enough D at the end of the day is unlikely. We are all on the go, and just with a sunny sky, need to know when to go all out or just chill out. Here's a rough idea of how much D you should be taking in, and some sources:

Age group

Aim for an intake of international units (IU)/day

Stay below IU/day*

Infants 0-6 months old



Infants 7-12 months old



Children 1-3 years old



Children 4-8 years old



Children and Adults 9-70 years old



Adults over 71 years old



Pregnant and Breastfeeding Women



*This includes D from both food and supplements

  • Cow’s milk
  • Fortified orange juice
  • Fatty fish like salmon and sardines
  • Egg yolks
  • Fortified yogurts

I take a Multi Vitamin along with a extra D supplement in the Murky Months. Like any other supplement there is a risk with sweeteners and processing methods. I stick with Cyto Matrix; they are a pharmaceutical company that makes supplements. All manufacturing is done in Canada. The raw materials are sourced from the highest grade, and vegetarian capsules are used (press tabs rarely contain the right source of the nutrient or vitamin for your body to absorb).They make a wide variety but my favourites are the Multi Matrix (men)/ Multi Matrix Women and the Vitamin D3 MCT Drops. Whatever your diet constraints, it's nice to have a quality, effective, safe source of everything you need.
