Listener Q&A:

As compiled, deciphered, edited and sometimes read by Brock Skywalker Armstrong, the Podcast Sidekick/Ninja.

The Science of the Runner's High

Celia asks: She is looking for a "Runner's High". She's been running since 2012 and has only experienced it a few times (with no common denominator or trigger). Do you know what causes the high and how she might be able to create one? She usually doesn't have trouble getting out the door for a training session but she can see how that might be a good motivator.

Is Vitamin B12 Megadosing Dangerous?

Jim asks: He has never heard us talk about mega-dosing with Vitamin B12. He is training hard and long for Ironman. He uses a drink called ZipFizz which has 41000% of the RDA of B12. The drink tastes good and it seems to give him an energy boost... but it could be placebo.

How To Track Every Element Of Your Fitness

Todd asks: He made a commitment to himself to be in better shape at 50 than he currently is at 46. He did the same thing at 30 for 35 and 35 for 40. He is looking for a quantifiable criteria or some number of metrics that he can test himself for, every couple of years, so it isn't just subjective.

In my response I recommend: -My Mass Made Simple podcast with Dan John -Blood Lactate and VO2 Max Testing -HRV and Pulse Oximeter testing as described in chapter 7 of Beyond Training book -Restwise -Mark's Daily Apple "Physical Fitness Standards"

Best Natural Foods for Babies

Emilie asks: What food would you and Jessa introduce babies to, as they move towards the world of solid food, and in what order? Also, is there any point in introducing them to gluten at all so they might be able to tolerate it later on?

In my response I recommend: -NOW Foods Gluten Digesting Enzyme

Healing The Skin Naturally

Allysa asks: She has the skin condition Keratosis Pilaris (unsightly red bumps or "chicken skin") on her upper arms. Some people grow out of it but she is 26 and doesn't think that will happen. Do you know the etiology of this? Is it a dietary, allergy, or hormone imbalance? Do you know of any food, creams or anything else that can help out with it?

In my response I recommend: -Book: The Hidden Plague -Gut Fix Pack -Vitamin C -Liver or Fish Liver Oil -Pantothenic Acid Cream from avocado oil

Is Creatine Safe?

Hank asks: He is looking for a really pure source of Creatine. Members of his family have the gene for Huntington Disease. While there is no cure for it, he has seen a study where they slowed the progress of Huntingtons by giving participants 15-30 grams of creatine. That is a HUGE amount of so he is looking for a reputable, good, safe, concentrated source. Also, is there anything they or their GPs should watch for when taking such high doses of creatine?
