I haven't seen any research to this effect. I would love to see links.

I'm interested in knowing if this stuff is merely SUPPOSED to be better for us, or if it has shown, with an effect on measurable endpoints, to actually BE better for us.

Thanks!

Re: multi-vitamin daily necessary or overkill?

I tried out that Fitday website... and with the exception of Vitamin D, every single vitamin/mineral category was >100% of the daily recommended amount. Some of them like C, B, etc. were like 400%-800% heh...

I eat a ton of veggies, a few fruits, meats, etc. The "paleo" thing I suppose... although I like peanuts and cottage cheese. Oh.... and my 5 daily chocolate kisses... I am NEVER giving those little friends up.

I sure as heck won't be buying any multivitamins. I am pretty sure I get all that I need from my food.

That's not true. Taking large dozes of antioxidants has been shown to increase risk for certain types of cancer. Also, vitamin C, enhances our iron absorption. Most people have too much iron in their bodies already, which combined with excessive vitamin C consumption can lead to some serious heart problems.

Re: multi-vitamin daily necessary or overkill?

Best to get all your vitamins and minerals from real food.

A multi here and there probably won't hurt. If you're eating well you shouldn't have to take one except maybe once or twice a week though.

Megadosing as stated before can actually increase risk of problems.

Most men, maybe. Premenopausal women, not so much.

If these percentages are the US-RDA, I'm not sure why they would have any more credibility than the "food pyramid".

i take 4g of fish oil daily as i don't think my whole foods can provide the omega 3 EPA & DHA.
thoughts anyone?
On 4g of fish oil, have you ever had your liver enzymes tested? I was taking 4-5g a day and my blood results came back with elevated liver enzymes. My wife (who is a Health Care Professional (PA)) showed me a study that showed that too much fish oil can elevate liver enzymes. I dropped down to 1g a day and now they are back in the normal range.

Not saying that you cant take that much, (because some people are fine taking that much) but you may want to get your blood panel done.

Oh! I encourage people to refute what I just said by posting or sending me reliable (journals, not news/blog stuff) info why I should take more and not overwork my liver. I liked taking that much and I want to fight my wife on the issue, but she has the upperhand now.

Only take as much as you need to in order to balance your n3/n6 ratio. If you're grain/legume/dairy free and all your protein is based on grassfed meat and seafood, you may not need any n3 supplementation at all.

Diet, sleep, stress, exercise are all a factor in how much omega 3 you should take so we can't exactly tell you if you need more or less than 4 grams.

I'm curious to know what was your average daily caloric intake?

Also, if you can export the data and send it to me I would love to see what that looks like. PM if you are willing to do that.

Which product were you using?

Can you provide a reference or link to that study?
