Q

There are 4 common Dietary Reference Intake (DRI) terms that the Food Nutrition Board use: EAR, RDA, AI, and UL. What do they mean?

A
  1. EAR (Estimated Average Requirement)–Avg amount sufficient for AT LEAST HALF the population
  2. RDA (Recommended dietary allowance)–Avg amount sufficient for NEARLY EVERYONE (I think of this as get at least this to be safe)
  3. AI (Adequate intake)–Avg amount sufficient for SOME GROUP(S) OF PEOPLE when RDA can’t be determined

(All of those were average amounts needed. UL is the only one different)

  1. UL (Upper limit, Upper Intake Level)–Highest amount to be safe

Q

What is Androstenedione?

A

A compound in the body that can convert to testosterone or estrogens, but more estrogen than testosterone. Studies found that even estrogen blocking supplements in combination with androstendione still don’t increase testosterone levels. So it’s NOT RECOMMENDED for men even though it’s popular. Low ergogenic effect, high risks.

Q

What is Dehydroepiandrosterone (DHEA)?

A

Produced naturally in the body and can serve as a precursor for androstenedione. It can be helpful for older men who have low levels of DHEA in the production of testosterone however too much DHEA has been linked to cancer, so it’s best to only take under the supervision of a doctor
