Recommended Nutrient Intake

Question:

“I am looking for “naturopaths’ advice” on vitamins and minerals levels -zinc, magnesium, calcium, chromium, iron, B12, D, C etc. I know the GPs recommended levels, which are not the optimum levels, I would like to know where I can find the “real” levels we actually need.”

Answer:

GP’s recommended nutrient levels, so long as the GP in question is staying up to date with changes, are generally coming from the best research available at the time. You can access this information via government websites such as this: https://www.nrv.gov.au/introduction

As you can see from this Australian Government page about Nutrient Reference Values, there are quite a few different methods used, with the approach used and amounts recommended varying between countries. It really isn’t as cut and dried as you might think: there is no definitive “ideal nutrient intake” list. Researchers, organisations, governments and countries don’t necessarily all agree, and the lists we do have are a ‘best guess’ for the average person. Continue reading

Synergy

From a nutritional perspective, synergism is the way certain nutrients within a food are interlinked and work together as a team. The fact that iron is absorbed better in the presence of vitamin C is a very simple example of synergism, but if I pick up my Nutrition Bible, the synergistic nutrients listed for iron are Vit B2, B12, citrate, copper, clic acid, histidine, lysine, molybdenum, and selenium.

In this, one of my favourite textbooks by Henry Osieki, Henry describes synergistic nutrients as those who “work together in particular metabolic pathways as well as cofactors that activate the nutrient in question.” He says that “supplementing a synergistic combination of nutrients with the nutrient in question will result in better health outcomes at (a)lower dose of the star nutrient for a condition.” Continue reading
