Clarification to podcast

In your interview with Josh Rabinowitz you asked, "Is the reason people don’t experience a flush with NR and NMN, because they’re typically taking only 500 mg to 1 gram. In niacin, flushing can occur at 30 mg if on an empty stomach in a few sensitive people. It does vary, but 500 mg of niacin will make most people flush (especially if on an empty stomach and if they are new to using it). I'm not sure how much niacin those precursors translate into but thought I would offer that info. Niacin Therapeutic Doses Strong effect raising HDL (1.5 g/d) Notable effect reducing LDL (2-3 g/d) Notable effect reducing TG (1.5 g/day)

BMD in drum corps alumni

Listening to AMA #37 and would be very curious to see data on those who have done years of marching band and drum corp, where a tenor drummer has a 45+ lb drum on for 16hrs a day moving and making directional changes at 215bpm. Not to mention the under nourishment that happens during the season.... Any idea on this?

Knee OA and rucking

Is rucking safe for someone with knee OA? Wouldn’t rucking be similar to walking when weighing more which is bad for knee health?

HRV improvement from chiropractic treatment

Can Peter speak to the research on HRV improvement resulting from chiropractic adjustment? Some are saying it is one of the top 3 ways to move-the-needle on HRV as it stimulates the parasympathic nervous system, and most aren't up for substantive meditation. Question Part 2: is Peter familiar with tonal chiropractic approaches and the overall nervous system effects in terms of patient well being (e.g. HRV, mood etc)?

Strength training for a 65 yo female with aging spine (DDD, some spondy).

How do I tailor my strength training so that I don't cause more low back pain. I took the last month off from strength work while on vacation cycling and also I have been hiking in the local mountains, and my back pain is almost completely gone. Makes me think strength work is causing more pain in my back. For example, can I do dead lifts, weighted squats, and ruck sack? Trainers seem to be all about adding weight. I have weaned myself off of triathlon/running, and am enjoying hiking along with my all time favorite: swimming. I swim in the ocean year round. It is a perfect way to start the day and loosen everything up before I go to the gym. Thanks for you advice. I know I need to do strength work, just don't want to cause more pain damage in my back.
