- WELCOME TO THE FIFTH SECTION IN OUR SERIES ON VITAMINS,

AND THE SECTION IS COVERING VITAMIN C. SO YOU USUALLY

THINK OF VITAMIN C AS SOMETHING THAT PREVENTS COLDS,

BUT VITAMIN C ACTUALLY HAS A RANGE OF DIFFERENT FUNCTIONS,

ONE OF THE MAIN FUNCTIONS IS THE MAINTENANCE OF

IT'S INVOLVED IN THE FORMATION OF COLLAGEN.

COLLAGEN IS A PROTEIN INVOLVED IN MOST OF THE TISSUES IN

OUR BODY AND IF YOU LOOK DOWN AT YOUR SKIN, WELL,

AND OF COURSE YOU CAN'T ACTUALLY SEE THE COLLAGEN.

MANY OTHER CONNECTIVE TISSUES SUCH AS THE TISSUES THAT

SURROUND MUSCLES OR THEY CONNECT BONE TO BONE SUCH AS LIGAMENTS.

WE DON'T NEED TO KNOW EXACTLY WHAT CARNITINE IS,

BUT CARNITINE IS INVOLVED IN THE TRANSPORT

NOW THE MITOCHONDRIA ARE GENERALLY THE WORK

SO IT'S A CO-FACTOR IN THE PRODUCTION OF CARNITINE

WHICH HELPS IN TRANSPORTING THOSE FATTY ACIDS.

THE, ANOTHER POPULAR, I SHOULD SAY WELL KNOWN

FUNCTION OF VITAMIN C IS AS AN ANTI-OXIDANT.

AND WE DO THINK OF VITAMIN C AS AN ANTI-OXIDANT.

IT'S THE MAIN, OTHER VITAMIN IT WORKS WITH IS ACTUALLY VITAMIN

E AND IT RESTORES VITAMIN E TO IT'S ACTIVE FORM.

VITAMIN E NEEDS VITAMIN C, SO THOSE TWO VITAMINS C AND E,

IN IMMUNITY AND IT DOES BOOST IRON ABSORPTION.

AND WHAT THIS IS IS A BREAKDOWN OF CONNECTIVE TISSUE.

SO IT'S-- YOU DON'T HAVE VITAMIN C YOU CAN'T MAKE COLLAGEN.

YOUR SKINS AND YOUR INTESTINAL [ INAUDIBLE ].

SO IF THAT CAN'T BE FORMED WHEN IT GOES TO CHANGE OVERS,

EVERYTHING IS CONSTANTLY REMODELING IN YOUR BODY,

BLEEDING OUT, OPEN SORES, UNABLE TO HEAL.

NOW THIS A WOMAN WITH A TRUE DEFICIENCY AND YOU

ACTUALLY DON'T NEED THAT MUCH VITAMIN C TO PREVENT SCURVY.

AND IN FACT YOU MAY HAVE READ IN YOUR TEXTBOOKS

THE STORY OF HOW THE BRITISH GOT THEIR NAMES,

LIMEYS AND IT WAS BECAUSE THEY WERE GOING OUT ON THESE

LONG MISSIONS ON BOATS, BUT THEY WEREN'T BRINGING

ANY FRESH FRUITS OR VEGETABLES OR IF THEY DID,

OUT THAT IF YOU JUST A LITTLE BIT OF LIME,

OF LIME THAT IT WOULD PREVENT THIS CONDITION.

THEY DIDN'T KNOW WHAT THE CONDITION WAS AND THEY

DIDN'T KNOW THERE WAS VITAMIN C IN THE LIME,

BUT THEY DID DEVELOP THE NAME LIMEY FROM THAT PRACTICE.

'CAUSE THEY WOULD NOT PERISH FOR A LONG TIME.

NOW VITAMIN C IS USED A LOT FOR THE PREVENTION OF COLDS

AND IT'S SOLD THIS WAY, IT'S MARKETED THIS WAY.

I HAVE PEOPLE TELL ME, YOU KNOW, IT'S WINTERTIME, OH,

ARE YOU TAKING YOUR VITAMIN C? AND I ALWAYS TELL THEM NO.

IT IS IMPORTANT THAT YOU HAVE ALL OF YOUR

NUTRIENTS AT ADEQUATE AMOUNTS IN ORDER TO PROTECT YOURSELF

AND TO BUILD UP IMMUNITY TO PROTECT YOURSELF FROM COLDS.

BUT THAT EXTRA VITAMIN C HASN'T BEEN SHOWN TO PREVENT A COLD.

WHAT IT WILL DO IS ACTUALLY REDUCE HISTAMINE.

HISTAMINE IS A CHEMICAL THAT MAKES YOU ITCH.

YOU'RE SCRATCHING, THAT'S A HISTAMINE REACTION.

SO IT WILL DECREASE THE SYMPTOMS ASSOCIATED WITH A COLD.

HAVE SHOWN THAT IT CAN REDUCE THE TIME PERIOD

OF A COLD MAYBE BY A HALF DAY, NOT DRAMATIC.

'CAUSE IT'S NOT GOING TO DO ANYTHING FOR YOU.

AGAIN I DO RECOMMEND THAT YOU HAVE AN ABUNDANCE OF

FRUITS AND VEGETABLES TO HELP YOU OBTAIN ADEQUATE

AMOUNTS OF YOUR NUTRIENTS AND THAT WILL HELP GIVE
