I usually stock up on Vit C and Zinc in the colder months. Wonder if its worth it now ?

Interesting stuff Jon, don't take them much myself barring a bit of vitC every now and then, and ZMA. Unfortunately it looks like they're two of the worst offenders?

I've heard about the risks of too many aggressive anti-oxidants before, but hadn't really thought about zinc too much.

I think I'll withhold judgement based on a single article, but interesting none-the-less.

High-dose ascorbic acid increases intercourse frequency and improves mood: a randomized controlled clinical trial.

BACKGROUND: Ascorbic acid (AA) modulates catecholaminergic activity, decreases stress reactivity, approach anxiety and prolactin release, improves vascular function, and increases oxytocin release. These processes are relevant to sexual behavior and mood. METHODS: In this randomized double-blind, placebo-controlled 14 day trial of sustained-release AA (42 healthy young adults; 3000 mg/day Cetebe) and placebo (39 healthy young adults), subjects with partners recorded penile-vaginal intercourse (FSI), noncoital partner sex, and masturbation in daily diaries, and also completed the Beck Depression Inventory before and after the trial. RESULTS: The AA group reported greater FSI (but, as hypothesized, not other sexual behavior) frequency, an effect most prominent in subjects not cohabiting with their sexual partner, and in women. The AA but not placebo group also experienced a decrease in Beck Depression scores. CONCLUSIONS: AA appears to increase FSI, and the differential benefit to noncohabitants suggests that a central activation or disinhibition, rather than peripheral mechanism may be responsible.

A randomized controlled trial of high dose ascorbic acid for reduction of blood pressure, cortisol, and subjective responses to psychological stress.

RATIONALE: Physiological responses to stress are considered disruptive to health. High-dose ascorbic acid has reduced indices of stress in laboratory animals. METHODS: We conducted a randomized double-blind, placebo-controlled 14-day trial of sustained-release ascorbic acid (60 healthy young adults; 3 x1000 mg/day Cetebe) and placebo (60 healthy young adults) for reduction of blood pressure, cortisol, and subjective response to acute psychological stress (Trier Social Stress Test, TSST, consisting of public speaking and mental arithmetic). Six subjects from each group were excluded. RESULTS: Compared to the placebo group, the ascorbic acid group had less systolic blood pressure (an increase of 23 versus 31 mmHg), diastolic blood pressure, and subjective stress responses to the TSST; and also had faster salivary cortisol recovery (but not smaller overall cortisol response). Cortisol response to 1 microg ACTH, and reported side-effects during the trial did not differ between groups. Plasma ascorbic acid level at the end of the trial but not pre-trial was associated with reduced stress reactivity of systolic blood pressure, diastolic blood pressure, and subjective stress, and with greater salivary cortisol recovery. CONCLUSIONS: Treatment with high-dose sustained-release ascorbic acid palliates blood pressure, cortisol, and subjective response to acute psychological stress. These effects are not attributable to modification of adrenal responsiveness.

I've got loads of articles from "wound" they done a whole issue on zinc supplements and the use of topical zinc in healing wounds and the main thing to come out of it was there was a right amount of zinc ~30mgs that gives the main benefits and higher doses stop the uptake of copper which is a bad thing. Sorry can't reproduce as i only have it in hardcopy

There's one of these things every week.....last week it was "Oral sex causes throat cancer" :rolleyes: ......just hope my missus didn't read it!!!!

Does that mean bye bye animal pak???

yomchi

Thats your personal option! There is only 1g of Vit C in Animal Pak though

Lads everyone dies eventually (well not me as I will be frozen until they find a cure for death or clone my body and transplant my brain)

There are loads of these things every other week. Its getting hard to know what to believe or do anymore. Vitamins are good.............but they'll kill ya in high doses

I think for people with less than perfect diets then taking a multivit is probably beneficial. For people who have a decent diet then why bother you're getting all you need anyway.

I'm going for the robot body/human brain option myself.

VHI gave me a pretty decent deal on it.

Nice!!!

What you going to go for, Bender from Futurama or T-800 from T2: Judgement Day

No, oral sex with someone who has contracted human papillomavirus strains HPV-16 or HPV-18 may cause throat cancer if the virus is active. HPV types 6,11,16&18 are the main viral strains responsible for cervical cancer in women. Thankfully there are now vaccines available from Merck (quadrivalent) and GSK (bivalent) that will considerably reduce the risk. So if the missus is worried take her to the doctors for her birthday and get her vaccinated

On-topic, I think that vitamin studies are important to have because of the growth of the supplement market. A good balanced diet and knowing that over-cooking destroys vitamins is important in achieving that balanced diet.

The study itself said that it couldn't control for other supplements being used and other factors. I wouldn't flush the multi-vitamins because of it. There should be a few follow-ups done, though the amount of money being made in this sector means any studies refuting it may need to be taken with a pinch of salt.
