Is that a peer reviewed piece of research??
Doesn't seem to be.
I dont see any actual reference to Vitamin C there.
Referencing Zinc, Iron, Copper etc in relation to a discussion on Vitamin C is of little use in fairness.
I don't see any reference in the studies subjects as being Athletes or sports persons??
That has been show by Meta Analysis of some of the more noteworthy studies like this( Hemila H, Chalker E, Treacy B, Douglas B. “Vitamin C for preventing and treating the common cold.” Cochrane Database of Systematic Reviews 2007, Issue 3. )
into Vitamin C Supplementation to be an important consideration.
That Meta Analysis showed a variance on the effectiveness of Vitamin C in fighting onset and length of the Colds in persons subjected to large amounts of Physical or environmental stress . . . . . and those not. It showed there was a greater benefit to such persons and a almost meaningless benefit to persons not under physical, environmental stresses. Meaningless because there was still a benefit but it was tiny.
A hard training Powerlifter/ Bodybuilder would certainly be subjecting their body to Physical Stress. . . .such as CNS stresses from heavy lifting, constant Muscle tearing and breakdown etc
So you shouldn't cite studies that do not focus on type specific activity . . .because like shown here, variations in activity alter the relationship to your result.
There is a huge body of peer reviewed research that illustrates the huge importance of Vitamins such as C . . . . for collagen production which links to connective tissue building, ligaments, skin, cartilage etc etc disease such as scurvy, Bone Mineral density etc etc
To tell anyone that supplementation with such vitamins is a waste of time . . . without knowing the exact details of their diet is wrong imo.
You have no idea if any person is getting the Guideline Daily amounts in their diet. . .or of they are deficient. If they are deficient then they certainly can benefit.
Only when you have those facts can you say it is or isn't a waste of time to take this vitamin or that vitamin/ mineral etc etc
