What is Vitamin C?

Vitamin C, or Ascorbic Acid, if we want to get technical, is arguably the most popular vitamin in the world, yet despite this, other than knowing that it helps boost immunity, many people don’t truly understand just how wonderful this vitamin really is. Vitamin C is a water soluble vitamin that functions as a catalyst for a whole host of natural processes within the human body. This vitamin helps to strengthen the immune system, it is essential for the formation of collagen, it can enhance the metabolism, and much more besides. Vitamin C is commonly found in a number of whole food sources, especially in fresh fruits and vegetables. However, to help make life even easier, and to help ensure that we do indeed meet our daily vitamin C requirements, vitamin C supplements are also available, and they happen to function incredibly well in the process.

How does it work?

Vitamin C works in a variety of different ways, because quite honestly, it provides so many unique benefits to the human body. For example, one way in which vitamin C functions, is as a natural antioxidant. Antioxidants help protect our cells and can help prevent diseases such as cancer. Toxins and free-radicals can invade our cells and change their molecular structure, causing them to mutate and to potentially turn cancerous. Antioxidants however, help to destroy and neutralise these free radicals before they have chance to cause any lasting damage. Vitamin C also helps to promote overall health and well-being, as the vitamin has been proven to help strengthen and boost the immune system. Vitamin C helps make the immune system stronger and helps to increase white blood cell counts, and so obviously, the stronger the immune system, the healthier we are as a result. It also helps to speed up the healing of wounds and injuries, so if an individual does happen to have a naturally high vitamin C count, if they did become injured, vitamin C would speed up the rate in which the injury healed. Vitamin C functions in a number of different ways as well, but the ones we have covered are perhaps considered to be the most prominent.

What are the main benefits of taking a Vitamin C supplement?

Some of the primary benefits associated with vitamin C include the following:

Can prevent cancer

As mentioned, due to the fact that ascorbic acid (vitamin C) functions as such a potent and powerful antioxidant, it can help to keep our cells nice and healthy, and can therefore prevent them from being damaged by free-radicals, which can cause them to mutate via oxidation. Antioxidants prevent oxidation, and therefore, vitamin C can help to prevent a whole host of different forms of cancer.

Promotes overall health

As you know, when your immune system is weakened, you are far more susceptible to various illnesses and diseases. Well, it just so happens that vitamin C has been proven to dramatically increase immunity, helping to strengthen and boost the immune system. This means that you will be less likely to suffer from common viruses and diseases, and if you do, you should recover much easier. Vitamin C is a great way of strengthening the immune system, making it a great supplement for promoting fantastic overall health and well-being.

Great for the skin

Vitamin C is also responsible for the formation of collagen, which helps to strengthen the skin and connective tissue, helping to improve elasticity. This helps to keep the skin looking firm and feeling tight and healthy, which is why many anti-aging products are packed full of various vitamins and antioxidants, including vitamin C.

Other benefits include:

  • Strengthens the immune system
  • Protects against cancer
  • Assists with weight loss
  • Boosts the metabolism
  • Great for the skin
  • Promotes healthy vision
  • Provides anti-aging benefits
  • Promotes healthy organ function
  • And more...

How and when should it be consumed?

For optimal results, experts recommend consuming anything from 40mg per day, all the way through to 500mg per day. For individuals with a weak immune system, or who are looking to simply strengthen theirs, a max of no more than 1000mg could prove beneficial. For optimal results, consume your supplements with a whole food source to assist with absorption.

Health Canada Recommended Dose (capsules): Adults: 1 - 2 Capsule(s) 1 - 2 time(s) per day.

Health Canada Recommended Dose (scoop): Adults: 1 Scoop(s) 1 - 2 time(s) per day.

Vitamin C VS Ester C

Vitamin C is sometimes compared with a supplement called Ester C, and although similar, the two are still very different and very unique to one another. Ester C is a PH neutral supplement that contains ingredients and compounds including: calcium threonate, and, dehydroascorbic acid. These are vitamin C metabolites, and because of this, some experts claim that the Ester C provides a more impressive bioavailability than regular vitamin C, which basically means that it is easier to absorb, and more can be absorbed. However, there is not enough evidence to prove this to be true as of yet.

What can it be stacked with?

Vitamin C is basically a supplement designed to promote overall health and well-being, and because of this, it can be stacked with other similar supplements. For optimal health, a vitamin C supplement with added zinc, a multi-vitamin supplement, an Omega 3 supplement, and perhaps a Glucosamine Sulfate supplement for the joints, will provide all the benefits you could ever wish for.

This was more of a trial purchase before I tried this brand's multivitamin out. These are certainly helpful for stress and immune response no doubt about it. I guess if you don't eat sufficient fruit then maybe add one of these in daily but I prefer the multivitamin with split dosing as this is a water soluble vitamin.

questions Ariel on 04/09/2018
Question: Hi Canadian protein; with the powder vitamin c, does it taste like anything and does it desolve well in water? Is it also best to take with zinc to boost the immune system if I am tired, and feeling weak?
Answer: Hi Ariel,  our vitamin C powder is very acidic tasting since it is ascorbic acid. You can also take it with Zinc if you wish.
