Mitochondria: Why They Control Everything in Human Health
04/12/2025 | 1h 42 mins.
Mitochondria govern everything. Watch this with the slides here: https://www.youtube.com/watch?v=mED1_L3wZbc Mitochondria convert your food to usable energy in the form of ATP, which is used to produce, maintain, repair, distribute, and organize everything in your body. Abundant health right now, and preserving your health throughout the lifespan toward your longevity, all depends on your mitochondria. In fact the best explanation for aging is that its a vicious cycle of declining mitochondrial function. We should always be thinking of mitochondria first. SSRIs, acne treatments, and statins are given as examples. Targeting mitochondria without proper testing has its own set of problems. This video covers the top things we should all be doing for our mitochondria and how to figure out our own mitochondria's unique needs. This is not medical advice and is for educational purposes only. 1:20 Mitochondria govern everything because they convert food into usable energy 7:25 Mitochondrial dysfunction drives aging 10:43 Depression starts with your mitochondria 17:26 The problem with SSRIs 21:59 Acne should start with vitamin A, zinc, B5, and mitochondrial function 28:00 Cardiovascular disease starts with mitochondrial dysfunction 40:26 Statins are mitochondrial toxins 54:00 Targeting mitochondria without testing can be dangerous: three examples. 59:45 CoQ10: no one dose and no one supplement for everyone. 1:04:30 Methylene blue can make your mitochondria worse if you don't need it. 1:07:48 The power of mitochondrial testing: three examples 1:15:14 Mitochondrial biology 1:17:32 Your mitochondria are pointless if you don't have creatine 1:18:20 What Mitome is testing 1:20:42 What Mitome reports look like 1:21:57 Energetic bottlenecks are like traffic jams 1:25:01 Organic acid testing of mitochondrial function 1:26:53 Other mitochondrial tests 1:27:44 Five things everyone should do for their mitochondria right now. 1:40:48 We all have unique mitochondrial needs Do You Have Hidden Mitochondrial Dysfunction?

SSRI Withdrawal Is Mitochondrial Dysfunction
23/11/2025 | 1h 29 mins.
Chris Masterjohn, PhD, Founder and Scientific Director of mito.me, explains why SSRI withdrawal is mitochondrial dysfunction and what to do about it. This is not medical advice, diagnosis, or treatment. 29 million Americans and about 5-10% of the world's population are on SSRIs, which have become the first-line treatment of depression. These can cause sexual dysfunction and emotional blunting in up to half of people, an unclear incidence of sleep disruption, and a rare risk of suicidality, self-harm, and new-onset psychosis. On the other hand, 20-50% of people who go off experience SSRI discontinuation syndrome. This can involve irritability, anxiety, mood problems, crying, dread, suicidal ideation, insomnia, nightmares, excessive dreaming, lethargy, fatigue, headache, tremor, sweating, anorexia, flu-like symptoms, nausea, vomiting, diarrhea, pain, numbness, tingling, feeling like something is crawling on the skin, electric shocks running through the brain or body, rushing noises, visual traces (seeing something persist when it is no longer there, or seeing moving objects leaving illusory streaks of light behind them, etc), dizziness, light-headedness, "brain zaps," vertigo, confusion, difficulty concentrating, amnesia, genital hypersensitivity, and premature ejaculation. A closely related problem is post-SSRI sexual dysfunction (PSSD), which can cause total inability to feel the penis for males or for females the genitals and nipples, loss of sexual pleasure, weak orgasms, decreased libido, erectile dysfunction, and premature ejaculation. PSSD is often associated with general anhedonia, apathy, and poor mood. In this video, Masterjohn maintains that the reason there are no good solutions to these problems is because we have completely misunderstood the role of serotonin and SSRIs. Serotonin's role is to help mitochondria adapt to changing demands for oxygen-based energy production. SSRIs enhance some of the mechanisms, and interfere with others. They enter the cell and stimulate independent mechanisms of mitochondrial stress adaptation, but in doing so they turn a cyclical and rhythmic pathway into a constantly stimulated one, creating mitochondrial dependence and making mitochondria vulnerable to new-onset dysfunction upon withdrawal. Once they make it to the mitochondria itself, the SSRIs act as mitochondrial toxins.
