Does vitamin C Help your Immune System?

The use of high doses of Vitamin C for viral infections and respiratory issues is well known.
For years, Vitamin C has been seen as the protector of those stricken with the flu or common cold.
‘Does Vitamin C help your Immune System’ is a question often asked.

Lemon Juice, honey and hot water is an old and well known remedy, given to the sick and ailing and hailed as a reliever of coughing spasms, pain and headaches related to the flu and common cold.
Let’s consider how it works.

How does Vitamin C help your Immune System?

Viruses use an enzyme (most commonly, a protein that speeds up chemical reactions) called neuramidase to attack our body cells.
This attack brings about a response from our immunity system and it begins to defend our system. Inteferon is a signal protein that an infected cell releases to warn other cells that a virus is present. This causes all the healthy cells to heighten their systems’ level of defence.

But the defence system can only work with the ‘tools’ it has.
A poor diet or a system compromised by over indulgence in alcohol, tobacco use, addictions, lack of sleep, little exercise and mental health issues will contribute little to the bodies defence system.

Vitamin C can inhibit the release of the Neuramidase enzymes that attack our bodies.
Vitamin C can INCREASE the amount of Inteferon produced, to trigger cell protection.
Vitamin C is not produced by the body.

Unlike humans, most animals do produce their own Vitamin C and as a result are resilient to viral infections. In fact, the defence system of these animals can massively increase the production of Inteferon– often above 20g per day, more than enough to overcome viral attacks.

Humans cannot, therefore we are reliant upon the ingestion of Vitamin C through diet or supplementation.
Neither can we store Vitamin C, requiring us to top up through- out the day.
Hence, the good old ‘Apple a day keeps the Doctor away’ and the well known hot lemon and honey remedy we all grew up with, which points to the truth behind the Tales.

A study involving 463 students was conducted, to record the effectiveness (or not) of Vitamin C.
When this study group got the common cold, they were given 1 gram (1000 mg) of Vitamin C an hour for the first 6 hours.
After this, they received 3g per day and painkillers.
The result? Those who received the Vitamin C regime reported 85% less symptoms.

Another study compared a high dosage of 6 to 8g/ per day of Vitamin C with a lesser 3 to 4g/ per day and found the higher dose more effective in having a significant effect on the common cold.
Vitamin C is water soluble, staying in the blood for a few hours before being totally excreted. To maintain high blood levels, it needs to be taken frequently during the day.
Higher doses of Vitamin C deactivate the effects of viral infection; in one study,
HIV was deactivated by up to 99%.
These results showed Vitamin C diminished viral protein production.

Another Study showed that giving high doses of ZINC shortened the common cold duration by 30%+
and that BLACK ELDERBERRY halved the recovery time, lessening it by 4 days.

These two natural and non-toxic agents provide good evidence of reducing duration and severity and less effecting of the immunity system by viral infections.

Over a 10 year period 293,172 participants in nine studies, who used 700mg of supplements each day were found with a lower risk of heart disease than those who did not take vitamin C.

Vitamin C is important to our health.
While it’s important to include Vitamin C rich foods in our diet, supplements also play a part.
Whether it’s hot lemon juice and ginger when you have the snivels or intravenous injections of high dosage Vitamin C, what you decide to do (or not do) is your decision.
Stay informed.
