Thread: Which Vitamin Tablet?
- 08-29-2012 #11
Zinc and Iron compete for absorption in the intestines, so large doses over long periods would cause iron deficiency.
There is no bio-available way for the body to store zinc for future use, like iron is stored in the blood stream, calcium in bones ..etc
It's also not easily absorbed on its own (10-40% only depending on different factors) and interferes with other minerals (calcium, copper), especially for people who don't eat protein.
So its probably best to take zinc with a form of protein (except for milk, take it at least 2 hours after milk) and allow some time (2 hours) between other supplements.
However I think that the best source of minerals and vitamins is food. Supplementation should only be considered for those with eating disorders, certain deficiencies, or malabsorption.

Oh and vegetarians needs to be careful about phytic acid
Phytic acid not only grabs on to or chelates important minerals, but also inhibits enzymes that we need to digest our food, including pepsin, needed for the breakdown of proteins in the stomach, and amylase, needed for the breakdown of starch into sugar. Trypsin, needed for protein digestion in the small intestine, is also inhibited by phytates.3

Mmm amalyse enzyme. They're what break down malted barley into delicious maltose for making beer.
Phytic acid eh? Gee it gets complicated doesn't it.. The body is incredibly complex, with the cascading chemical reactions and effects. I feel that mostly my body seems to know what it wants to eat. Does anyone else get that? Luckily for me I like mostly good tasting healthy foods, so I pretty much give in to all my various food cravings

I am vegetarian and eat pretty healthily (am reasonably fit too) but I thought a vitamin tablet would help with growth etc. I drink protein shakes etc because i'm building muscle atm and take Wellman or Optimen (swap weekly between them as Optimen is kinda 'heavy'). I wasn't sure if it contained enough zinc or stuff. I give out a good sized load once a day but when I go again its not so great. Still can keep a good erection though... so I'm not sure if I need any other special supp?

Zinc is exerted in urine, sweat and ejaculation, it is a micro nutrient (not required in large quantities) and proteins, garlic and onions help with bio-availability and metabolism of both iron and zinc especially from plant sources.
Most vegetarians rely on lentils, beans, seeds and legumes and those are filled with phytates, so thry need a special treatment before cooking to help reduce/break phytates so the nutrients are more available to the body.
Phytates are anti-nutrients, they act as a natural preservative to the plant, animals have enzymes that can break it so they can benefit from their food, while humans have very little to none of those enzymes so we have to sprout or soak and cook food to be absorbable.

Which ever supplement you choose take it with Bioperene, it makes the vitamins and minerals more bioavailable. 25%-50% they say.
"How much is enough"?

I think the name Bioperene is a brand name, and the actual compound in question is piperine. Looking at good old wiki, it increases the bioavailability of some things. The effect on resveratrol looks interesting to me. Resveratrol is found in the skin of grapes and one of the alleged effects is increasing an organisms lifespan. It just so happens that I am an organism myself. Eureka!

I've heard of grapefruit juice having all kinds of unexpected interactions, and if you're on any medication you should at least be checking in to it before drinking. Surely someone has found a way to market that horrid stuff in that way. Lol. I'm not a fan of it.
