Questions this episode answers
Yes, weed is bad for blood flow; it can add to erectile dysfunction, anxiety, and paranoia. Stop using it for 90 days and get testosterone labs.
Indirectly, because fluoride in mouthwash kills oral bacteria that produce nitric oxide, reducing blood flow needed for erections.
Avoid over‑the‑counter products that may be tainted with prescription drugs, buy from trusted sources, look for USP or similar certification, and remember no supplement works without proper diet, exercise, sleep, and stress management.

This podcast is for you, the modern man. I'm Dr. Ann Twung, your host. I'm an intimate health medical doctor and bestselling author of the book Erectile Dysfunction Fix. I'll do a deep dive into sexual health and performance and how it affects men of all ages and backgrounds. So let's get started and be sure to visit my website at sexualhealthformenpodcast.com for more information and resources from the show. See you on the inside.
I am 32. I noticed I'm not as horny as I used to be, but I am athletic. Do you think weed is bad for blood flow? Yes, weed is bad for blood flow. Weed is not something your body makes. If you put a foreign substance in your body, then your body's not going to agree with it. Okay. And weed also makes you kind of apathetic. I don't know how much you smoke. Is it every day or is it every day or a large amount? But it does make you apathetic. In my experience, when I see young men that smoke weed, it tends to add to their ED and their anxiety as well too, because weed also adds to paranoia. And you're athletic. That's great. You're young. You can definitely reverse your libido. So you're not as horny. That means that you're probably— your testosterone is low or low arousal, decreased sensitivity. So stop the weed, give it 90 days and see where you're at. You're young, you're athletic. You should be able to reverse that. No problem. Get your testosterone levels checked by bloodwork. You go get the bloodwork done. In fact, you don't even need an order for bloodwork for testosterone. And one of my videos, I talk about the bloodwork that you need to get if you have ED. So look for that video. But if you're going to get testosterone level, you should be getting a total testosterone, free testosterone and sex hormone binding globulin, or SHBG, on your blood work to look at your testosterone. Well, we're seeing more younger men now with lower testosterone, and that's because of no exercise, poor diet, poor sleep, and porn, and smoking, and cannabis. I hope that helped. Thank you for asking that question and being honest about that, because it is a real problem. You don't know. We normalize weed. Everybody smokes it. Anything, but weed is not something that is natural in your body. So if you're putting something that is not natural in your body, your body's not going to like it, right? It makes sense. Your body doesn't make nicotine. Your body doesn't make THC. So when you put something foreign in your body, it's going to affect you wrong. So you have to think about that. All right. Even like Viagra, you're putting that in your body, then your body initially, it's going to forget how to get an erection on its own. So I hope that helped.

Does mouthwash cause ED? Well, indirectly, because when you take in mouthwash that has fluoride in it, so fluoride, when you rinse your mouth with fluoride, mouthwash, it kills the bacteria in the back of your mouth. And when it kills the bacteria in the back of your mouth, it makes you make less nitric oxide. And when you make less nitric oxide, that will affect the blood flow when you get an erection. So indirectly, mouthwash do cause ED. So that's why you should stop taking fluoride products. You should stop using toothpaste that has fluoride. Stop using mouthwash that has fluoride. They do make toothpaste and mouthwash that are non-fluoride. That's what I use, a non-fluoride. They do make that. Also, when you take antacid medication like omeprazole, Tagamet, Pepcid, Zantac, Nexium, those medications can also decrease your nitric oxide because it decreases the acidity of your stomach and that will affect how you make nitric oxide. So these are the things that will affect less nitric oxide production. So that's how mouthwash can indirectly cause ED. Does that make sense? So many supplements are trashed or tainted. How can us average people safely navigate supplements? That's a good question. There are some supplements that are tainted with Viagra in it or Cialis in it, and I have seen it being sold at gas stations. And it's not supposed to be like that because those are prescription meds, but they add that in and it's for sale over the counter. And so that's very, very dangerous because there's a reason why Viagra and Cialis are prescription meds, because if you concurrently take blood pressure meds with Viagra or Cialis, it can lower your blood pressure to a point where you could have a heart attack or pass out or have a stroke. So Viagra, you know, do interact with other medication as well too. And that's why you need to go see a doctor. And if you have a heart condition and you take Viagra, it will not go well for you. But some of the supplements that are sold, especially at convenience stores like Wawa, Sheetz, 7-Eleven, then you make sure you look at the ingredients on the box. But most of the time, I would buy from people you trust. I wouldn't buy something that is in the gas station store or 7-Eleven or things like that. They advertise wrong and they over-advertise, they promise stuff. But I would tell you this, I'll be so honest with you guys. There is no one supplement that will get your erection back without you doing diet, exercise, sleep. Let that sink in. If you don't do any of those that I just mentioned, the four pillars of sexual health, diet, exercise, sleep, and stress reduction, No supplement is going to work at all. Even the nitric oxide supplements and the Libido Plus, no one supplement is going to get your erection back if you don't change your diet or your exercise. So I'm just going to be real with you guys. I am, because I want you to know that. So you can't just take a supplement and just eat your French fries, eat your hamburger, don't exercise, Netflix binge, swirling on your phone all day long, that's not going to work. Just be like a drop in the ocean. Because I don't want you to waste your money. There is no such thing as one supplement. I don't care where it's made in Africa or Nepal or in China, whatever.
Right.
It is touted, oh, miracle supplement. There is no one thing that is a miracle supplement. There isn't. You have to fix the cause of why you have ED in the first place, which is due to poor blood flow. You don't fix that, then nothing's going to work. So it's like you take a supplement. It's like you have a car and the engine of the car is a problem. But how you fix the car is you're just going to add a little bit of oil and you're just going to put some wax the outside. And then that's all you're doing, right? So you take a supplement. It's like adding the oil in the car. That's not going to work. 'Cause the engine needs to be fixed. So you need to fix your foundation. You need to fix your body to why you're having decreased blood flow. And oftentimes, guys, it's as easy as changing your diet. It's easy as like, you know, maybe I shouldn't be eating a hamburger every day. Maybe I shouldn't be eating a steak every day. Maybe I should cut down that fries. Maybe I should not drink Coke or Sprite every day. I talk to men. I know what you guys drink. I have men that comes in and drink like 10 Sprite a day. Or eat a steak every day, french fries every day, and bacon eggs every day. The endpoint is you have to change your foundation, which is the inside of your body, to fix the cause of why you have decreased blood flow. I have supplements that's available too, but I'm getting real with you guys. I'd rather be real with you guys and tell you the truth, but no one will. And I'm telling you guys this because I know what works. We have seen men that literally had prostate cancer, had their prostate removed, and men that had ED for 10 years. And when they start eating better by following the Mediterranean diet, then they start to exercise, they take the Good Morning Wood smoothie. When they start doing that, their ED improved. They're starting to have some morning wood. They really starting to have some morning wood. And so I want to tell you that you can do this. We have seen men that have reversed this. Okay. And so you can do it. I'm just trying to get real with you guys. And so to answer your question, no magic supplement. How you can navigate is from somebody that you trust. And also if you're going to get something, there's usually an accreditation agency that tests supplements. You can see a signal called USP, U like in unit, S like in SAM. Pelican Paul, USP, you'll see like that logo on the supplement bottle. So you can check for that as well. Okay. I hope I answered that in a long-winded way. Collective intellectual.
