It also can boost your immune system, making you less likely to get sick and rebound faster when you do. Master Tonic even supports your liver to help your body detox naturally.

    I love how it makes me feel, but the alcohol in it literally burns my mouth. Like it hurts I can’t use it. I wanted to love this product

  2. Sydney Hand (verified owner)

    This is a daily tonic for me!! I have seen significant change in my hormone and energy levels and I have most definitely noticed a decrease in stress and feeling overwhelmed.

  3. LG (verified owner)

    It recommends for you to put the drops under your tongue. I used it for the first time today. I did the drops under my tongue, and it immediately started burning. My skin is still raw several hours later. The taste is also very strong. I have tried 3 other tinctures, and they didn’t burn like this one, so I assume it was the alcohol. I may have to mix it with something to try it again.

  4. Jessica (verified owner)

    I feel the difference, but the taste is killing me (not literally lol) and burning my mouth.

  5. Wendy (verified owner)

    My Dr wanted to put me on prescription meds for anxiety & pmdd. I’ve been feeling lazy & moody lately and now i needed to do something. I decided to try master tonic to see if it would make a difference in my mood & over all health before taking any pills. It’s been about 3 weeks & I can honestly say I feel better. I feel less moody, have more energy & haven’t been flying off the handle with my kids as easy. I’ve taken quite a few supplements but this alcohol flavor is pretty potent, I make sure to follow it with nourish her naturally really fast to mask the taste! I say this product is definitely worth trying if you’re on the fence about it.

    This is amazing!!!! I just started using about a month ago and it really helps to stabilize my mood. I couldn’t believe how fast it works within 10 min I was feeling more myself and less reactive to things. It made me feel less frazzled inside and calms my mind. I love that it also provides immune support.

    LOVE the Master Tonic!! So I have been using the products for not long but this is the one that I’ve noticed the biggest difference with so far. Some of the other ones I’m sure are working internally and I may not notice as much of a difference right away. This one took one week and I noticed a HUGE difference. My stress level was through the roof and my anxiety level was also high, I was on edge all day – every day and it was affecting my health. After one week of being on the master tonic I’ve noticed a huge difference in how I handle stress. Things that would set me off before are rolling off my back a lot easier. It doesn’t make me feel odd or weird it just makes everything much easier. I’m excited to try a few other products as well. I’ve also had great success with the sleepy time, falling to sleep quicker and staying asleep. So far, I am very impressed with the product line
    and will continue to be a customer!. The 5 mushroom super blend is next on the list!

  8. Anna (verified owner)

    I take this postpartum and as I mother my toddlers. I notice an increase of energy and calmness I can’t quite describe. Thankful!

  9. Gabrielle Schafer (verified owner)

    I LOVE LOVE LOVE this product. I have done a lot of things to help with Adrenal support over the years and I feel this one made the biggest difference in my apathy and fatigue. My mood is so much better and it even helps with hormonal depression.

  10. Heather R. (verified owner)

    This is one of my favorite products! I can feel such a difference in my body when I am using it versus when I don’t! I love boosting my immune system and giving my body such great support by using this simple tincture! My husband has started using this as well and is equally impressed with its performance!

  11. Debbie Runfolo (verified owner)

    Although all the tinctures are good, this one is my favorite. So many good ingredients! I take it every morning and my stressful day is much calmer.

  12. Lillie King (verified owner)

    I’m excited to try it, as I’m needing more energy to keep up with my very energetic toddler. But wow, the taste is VERY potent, I have to take it with juice

  13. Laura Meadows (verified owner)

    I have an extremely sensitive system and this unfortunately didn’t work for me. I tried just one or two drops a day and it left me with increased palpitations (I already have these) but it looks like it helps many other people! I’ve found the best thing for me is just fresh orange juice and Celtic sea salt on the empty stomach. It helps my adrenals and I’m so much less stressed. I love earthleys other products.

  14. Alexis Miller (verified owner)

    THIS!! One of my top 5 favorite products. If I could only choose 5. One of the first Earthley products I ever tried. I just felt better when I started using this.

  15. Alexis (verified owner)

    This is my go to tincture! I feel so much better after taking this!

  16. Kara Lewandowski (verified owner)

    I love this stuff! I feel amazing after a week! I can’t really handle it under the tongue but I have been putting it in a shot glass with water!!!

  17. Emily Darnall (verified owner)

    WOW! I had been extremely rundown – had trouble getting up in the morning, or making it through the day without a nap. The first day I took it, I noticed already that I seemed to feel less foggy, and had a little more energy. The second day? I feel like a brand new person. I’m shocked at the dramatic difference. I woke up clear-headed, ready to take on the day. I didn’t need a nap, and I didn’t lose my temper with the kids. I will say, the taste is…pungeant…but, it’s totally worth it. Seriously!

  18. Rebecca Sharp (verified owner)

    This is great but the taste is gross. I pair this with nourish her and oyster min too

  19. Rachel

    Between this and the mineral capsules, my hormones have regulated so much! A noticeable difference in the right direction, especially regarding my cycle.

  20. Molly (verified owner)

    I’ve just started using this product but could definitely feel a difference in my mood right away. I’m working on supporting my body healing from chronic stress along with balancing my hormones. This is a great option. The only reason I can’t give it 5 stars is the taste. It’s really hard to get over and I have to eat something right after because it’s so strong. I had read the previous reviews about it and that seemed to be a common theme. They are not wrong on the taste, but the remedy itself is great! Just grab a snack after ha!
