In this solosode, you'll explore how to make peace with tinnitus after acoustic trauma, including the half dozen different root causes that can drive it and the specific supplements and technologies with research behind them, why cardiovascular fitness itself seems to protect your hearing as you age, and whether tattoos are actually as risky as people think, from the heavy metals hiding in colored ink to what a major 2024 study found about tattoos and lymphoma risk.
I also break down a new study showing you can get the same heat shock protein boost from heavy resistance training that you would normally only get from a sauna, why stacking a hard workout with a sauna session afterward may give you the best of both worlds, and take a closer look at a study making headlines for supposedly debunking the whole eating before bedtime rule, because the fine print tells a very different story than the headline does.

| 0:00.0 | My name is Ben Greenfield and on this episode of the Boundless Life podcast. |
| 0:05.1 | In this episode of the Boundless Life podcast, how to maintain muscle on a GLP 1, why protein stops working as you get older, the truth about eating before bedtime, and more. |
| 0:18.4 | Welcome to the Boundless Life with me, your host, Ben Greenfield. |
| 0:23.1 | I'm a personal trainer, exercise physiologist, and nutritionist, and I'm passionate about |
| 0:27.7 | helping you discover unparalleled levels of health, fitness, longevity, and beyond. |
| 0:44.9 | Bitamine, vitamin, vitamin, vitamin, vitamin, butamin, however you pronounce it, E. Let's talk about vitamin E. |
| 0:54.7 | Not a lot of people talk about that. It doesn't seem as sexy as like D or B. But most of the vitamin E that you find on the shelf is kind of crappy. It's alpha tecoferal. And that's a problem because that's just one fraction of the vitamin E that you find on the shelf is kind of crappy. It's alpha tecoferral. |
| 0:59.7 | And that's a problem because that's just one fraction of the vitamin E family. What's often missing are taco trinoles, taco trianols, not just tecoferols. Tococryanols are a different set |
| 1:07.3 | of compounds with some of the more interesting vitamin E research around cardiovascular |
| 1:10.9 | health and aging and brain function. And once you understand that, it changes how you look at |
| 1:16.1 | vitamin E. So there is this stuff called taco trienols vitamin E. It's made by extend life. So instead of |
| 1:22.5 | just focusing on alpha to cough roll, the extend light formula is built around delta and gamma tachotrinals, the forms of |
| 1:31.1 | vitamin E that have the strongest body of research behind them. Now there's an important nuance here. |
| 1:35.6 | High doses of alka tocopherol can actually interfere with tachotriinal absorption. That means not only |
| 1:42.4 | are many standard vitamin E supplements, not just incomplete, |
| 1:45.3 | they're actually working against what you're trying to achieve. So this formula from Extend Life |
| 1:49.6 | avoids that. No unnecessary fillers. No competing form. Just targeted support built around the forms |
| 1:55.8 | of vitamin E that matter. Extend Life has been formulating supplements for over 26 years out of New Zealand. |
| 2:02.3 | They publish a COA certificate of analysis for every batch, that level of transparency is pretty |
| 2:07.5 | rare. And when you look at the research, especially the work around tachotriennels and their role |
| 2:11.7 | in cellular and cardiovascular support, it becomes clear this is a different category than |
| 2:16.8 | standard vitamin E. And right now, you |
