This Friday's episode is a detailed solo recap of my interview with world-renowned protein researcher Dr. Stuart Phillips. In this science-packed conversation, we busted some of the most persistent and misleading myths in women's fitness, protein metabolism, and muscle growth. From fears around mTOR and kidney health to the truth about cycle syncing and menopause, this episode is all about clarity, confidence, and facts.
If you've ever been confused by conflicting advice online — especially around how women "should" train or eat protein — this one's for you.
TOP 12 MYTHS: The RDA for protein, high protein diets & kidneys or bones, mTOR activation is bad for longevity, building muscle during your luteal phase, timing rules for protein and fasting, do women need less protein than men, muscle loss and menopause, lifting heavy vs moderate to get results and much more!
Dr. Phillips brings research-backed clarity to all of these claims — including findings from his lab and collaborations with Dr. Lauren Colenso-Semple. Whether you're in your 30s, 40s, 50s, or beyond, this episode will empower you to focus on what actually works.

| 0:00.0 | Welcome to the Optimal Protein Podcast. I'm Vanessa Spina. |
| 0:05.4 | Hello, my friends, and welcome back to the Optimal Protein podcast. I'm your host, Vanessa, and I am so |
| 0:11.2 | thrilled to bring you today's special Friday recap episode. Now, this week, I was joined by the legendary |
| 0:18.5 | Dr. Stuart Phillips, professor at McMaster University, |
| 0:22.5 | one of the most published researchers in muscle physiology and protein, and someone who has |
| 0:29.3 | made it a mission to educate and empower women through science and not fear. So in today's |
| 0:37.0 | episode, we are recapping and breaking down the top |
| 0:40.3 | 12 myths that Dr. Phillips helped us bust wide open on Monday's episode, myths that are all |
| 0:47.4 | over social media, especially targeted towards women in the areas of protein intake, hormones, fat loss, and lifting weights. |

| 1:36.6 | But here's the good news. Magnesium breakthrough by bioptimizers can help. Now, this is my |
| 1:41.9 | favorite supplement, the only supplement that's always in my travel bag |
| 1:45.9 | or suitcase. I take it with me everywhere I go, including the baby hospital when I gave birth twice. |
| 1:53.2 | Not only does it help with sleep, it also really, really helps me with restless legs in both of my |
| 1:59.3 | pregnancies. So I don't leave home without it. |
| 2:02.2 | It's the only supplement that combines all seven essential forms of magnesium, |
