In this video, we’re going to talk about the side effects and benefits of ashwagandha. Ashwagandha is a powerful herb that helps to reduce stress and anxiety. Along with stress management, ashwagandha has numerous potential health benefits, including the following:
•Reduces nervousness
•Helps reduce cortisol
•Increases VO2 max
•Increases testosterone
•Improves sleep
•Improves recovery
•Lowers blood sugar
•Helps improve insulin resistance

However, there are some things to consider before taking ashwagandha. Avoid ashwagandha if you have a hyperthyroid condition like Graves' disease because ashwagandha speeds up the thyroid.

Because it lowers blood pressure, it’s best to avoid ashwagandha if your blood pressure is already on the low side. If you have low cortisol, you won’t want to push it even lower with ashwagandha. Pregnant or breastfeeding women should also avoid ashwagandha.

Don't take ashwagandha if you’re sensitive to nightshades or have a genetic problem that causes you to have too much iron. If you take too much ashwagandha for too long, some people describe feeling no emotion or feeling numb.

Most people who experience adverse ashwagandha side effects have taken it for too long and in high doses. Consider keeping your ashwagandha intake at around 600 mg daily, broken into two 300 mg doses. It’s also best to limit your intake to two months at a time.

    According to Ayurvedic principles, ashwagandha should not be taken for more than 2 months … and this is coming from my dietician who is a trained Ayurvedic doctor. So doctor Berg is right …

      Same here. Been on and off for 2 years, helped significantly lower my chronic stress. But then again, I knew not to take it everyday from the get go because I did the due research and found other people had these side effects.

    • @srozaardnet5630 says:

      Yes. I learned this the hard way. My Naturopath recommended a tea with ashwagandha to help me lower my cortisol. Immediately after drinking it, my tongue swelled up & my throat tightened. I had to make a fast trip back to his office for assistance. Scary. I avoid nightshade vegetables, but at the time I was unaware that ashwagandha was one.

    I love my Ashwaganda gummies and I only take it periodically when I feel I need it.

  • @joannad2825 says:

    I’m so glad dr Berg discussed the side effects of ash and the importance of not taking it long term. These “natural” supplements are not as harmless as we think. Ashwaganda was recommended to me to help deal with anxiety and other symptoms of perimenopause. I was on a dose of 600mg for 2 years. It did work for a while but then I started having severe side effects. Depression, anxiety, loss of feeling pleasure (that muted feeling that Dr Berg mentions), low blood pressure (I even fainted once) and general lethargy for much of the day. It also wreaked havoc on my digestive system. When you try to come off it, it can take some time as it is stored in your body fat. Please be careful and only use short term if at all.

      Agreed. Like Dr. Berry says “Rat turds are natural too.”

    • @pamelatimbush3762 says:

      Thanks for informing us. I was considering taking it because I read somewhere a lady was able to get rid of the ridges in her nails and I miss having beautiful nails and I would’ve loved to have it help with menopause symptoms, and then all the sudden I hear Dr Berg’s video here where if you have low blood pressure you shouldn’t take it. Then I read your comment where you passed out 😮 😱 bless your heart that had to be scary.
      So I think I will pass and just search for other ways to help with different issues.
      I know as we age we get more ridges in our nails but I don’t like when they split up to the quick it hurts. And I wish he would do a video about why some people have their blood pressure go low the more pain we’re in as not ONE doctor has ever been able to tell me they just look at me like I have 3 heads😢.
      I did have a gal tell me her thoughts on it at my primary once and I wish she was still there and I could have her write it out. It has went dangerously low once when I was in so much pain and the nurse ran out of there like her tail was on fire and the doctor said how low is it and all the sudden she was beside me and they thought I broke my neck, but I didn’t it was pain in my neck/back and I got massive migraines to the point they were afraid I was going to have a stroke 😳😱😭.
      Thankfully yrs later we finally have those under control! Going through perimenopause and menopause is NOT FUN and I wish more men understood we’re not trying to be mean or grouchy etc. our bodies are just not cooperating with us!
      Sorry for the long post, hope your comment helps others too.
      I appreciate it and what the dr said I will be passing.

    • @joannad2825 says:

      @@user-uj3ov9jf9ki would suggest slowly weaning yourself off of it (if you have been taking it for more than a couple of months). For example – from once per day to every couple days for a couple weeks, and go down from there. Depends on how you are feeling. I improved pretty rapidly once it was all out of my system. Take care.

    The doctors i used to go to had me on 6 diffrent prescriptions. Now i take hair fomula, adrenal stress, and trace minerals. I have not gone back to the doctors for at least 6 years now. Im in excellent shape, eat healthy and exercise a lot. At first i was taking to many of the adrenal stress, but i lowered my intake a little, and have felt like im using a cheat code in life. Stress/anxiety/anger no longer have a home inside me. I trust DR.BERGS science.

      I have low thyroid and I have taken ashwaganda periodically through out the years and never felt good while taking it. So I’m not going to recommend it. Same with selenium. I just read some studies where it showed that selenium does reduce t4 and t3 uptake, therefore good to treat HYPER thyroid, but not good for hypothyroidsm

  • @mlmallory2780 says:

    I love Ashwagandha and used it for years, unfortunately it caused me to have a upper gi bleed. It took me a bit to realize that it was causing the bleeding. Once I quit taking it the bleeding stopped. Still I’m thankful for it because it helped me through a very stressful time.
