Uncovering the Benefits of Optimal Nutrient Dosing

By Michael A. Smith, MD

In 1941 the U.S. National Academy of Sciences established the recommended daily allowances (RDA) for vitamins and minerals. The RDA is the daily dose of a nutrient that’s needed for the average person to stay healthy. Although updates are made every 5 to 10 years, the RDA for vitamins and minerals haven’t changed significantly over time.

Today, most of us use the recommended daily intake or RDI. This is basically the same thing, but is more specific in that it states the daily dose needed to keep 98% of people healthy. Because it has a broader scope, the recommendations are usually a bit higher than the RDA.

Now that we’ve got that out of the way, here’s our point: both the RDA and RDI are pretty much useless. We believe that it’s time for our government to support what we call the ODI … ”optimal daily intake.”

What is Optimal Daily Intake?

Life Extension enthusiasts prefer what we call Optimal Daily Intake or the ODI. Dosing vitamin and minerals at this level goes far beyond protection against deficiencies and enters into the world of disease prevention, treatment and even human longevity.

By the way, ODI is not an official dosing system. We made it up. However, we do think it should be official. So our goal is to continue educating people on the potential health benefits from higher nutrient dosing. And there’s a lot of them, some of which you may not have known.

The Lesser Known Benefits from Higher Doses

The following table lists the ODI of the vitamins and major minerals. It also includes some of the lesser known health benefits obtained from taking the ODI. So let’s dive right in.

As an educated consumer, you should get into the habit of looking at the back of the label … not the front. The front label is nothing more than marketing jargon to grab your attention. The real information is on the back. Identify each vitamin and mineral and make sure you’re going to get optimal dosing from the product. If not, keep looking!

Shouldn't your table be based somewhat on daily caloric intake and body weight? If it is, where is the data? Are you saying a 200 pound male needs the exact same as a 150 pound female?

I came here to ask the exact same question as Zach Bennett did . . . will check back for an answer.

Zach Bennett - We base our suggestions to support the best anti-aging effects (based on research), not on body weight. So, yes these dosing suggestions are for adults of different body weights. Blood testing helps to determine nutrient deficiencies and optimal dosing amounts.
