Garcinia Cambogia Side Effects

Garcinia Cambogia made its grand entrance into the weight loss supplement field after Dr. Oz showered it with accolades in late 2012. We initially sought reviews on the product in January 2013, and the response has been mixed. Here we take a closer look at some of the known and rumored side effects of garcinia cambogia.

Possible Side Effects

According to WebMD, possible side effects include:

Additional (Anecdotal) Side Effects

  • Cramps

    Thanks, guys, for the honest feedback on here. I just took my 2nd dose of Garcinia Combogia and had to stay in bed all day! Of course I’ll lose weight, I feel too bad to eat! I could not find any opinions, good or bad, about this product–only where to buy it! That is, until I stumbled on this stream of comments. Thanks for assuring me I’m not crazy!

  • Marcie

    I took this product 2 days in a role, and I now have a bad rash on my body. I am going to stop taking this and see if it goes away. It is NOT a very pretty rash!! :(

    • sonya fox

      I have had the same thing happen to me. Only after one day, feeling nausea and very dizzy when I woke up in the morning. I had to go back to bed. Will persevere with the product for another day….if still the same I will give it away. Shame because it is very expensive!!

  • Andy

    I have noticed increased bowel irritation/ piles/haemorrhoids

    Does anyone else have these effects?

  • Ceilidh McPherson

    I started taking 4 days ago and i feel awfully run down so tired and feeling gassy too I have a little bit of a blocked nose but not to much and sometimes a little headache now and then I havent weighed myself yet I also go to Weight watchers so Im eating healthy but not when im working. I work part time in Mcdonalds so when im working i have a cheeky burger.I havent experience any other side effects Sept from Feeling Really Run down and tired.I feel like my stomach has went down allot so hopefully I do lose weight

  • wendy

    I have been taking GC for 3 weeks and I had diarrhea, gas, severe stomach pains, constant headaches and sleeplessness. However, the worst one is the horrible rash that I have all over my body. It’s been there a week and just keeps spreading. I haven’t been to doc yet because everyone keeps telling me that I’m overreacting and its just heat. To those who did go to the doc, did you require meds for the rash or did it just go away?

  • Babydoll

    I have been talking garcinia Cambogia for three days now I feel nausea alot now don’t have a appetite like that at all I go to the bathroom more o hope it works

  • CoquetteI

    So glad to find this site.
    Been taking this for almost a month. I feel rundown, dizzy, bloated, gassy & headachy.

    I can’t sleep and I get cramps sometimes. I’ve been afraid I was having either a heart attack or a brain tumor. Seriously. I can barely leave the house for having to go to the bathroom so often.
    Since these symptoms started a few weeks after using this product, I decided to search the web to find side effects.
    Will stop using this stuff and hope these symptoms go away. I only want to lose 14lbs, but would like to have a life while I’m losing.

  • Dolly

    I never wrote a review before, but I have tried so many pills always herbal just to be in race to lose weight.
    After reading too much about garnicia combodia, saw Dr Oz comments. Anyway I ordered Miracle brand. So I took 1 each day for 2 days, night couldn’t sleep and had horrible headache, dizziness. I did not took the capsule today and stopped so I can start thinking clearly.
    I know that we all know losing weight can not be a miracle. It took so much time to gain those extra 10kg. Not going to come out easy. Healthy diet and exercise is the key. We all know it but always looking for quick fix. These companies keep bringing new products on shelf to empty our pockets. If there is a miracle pill, then they should be only selling that one.
    Please don’t risk your health & waste ur money.

  • ceilidh

    Ive been on this for a week now and i have only lost 2 pounds but I have side effects dizziness upset stomach cramps a little cold, I just feel so drained and run down. I honestly think im going to stop taking them cause i just feel ill and its horrible.

    • Lana Avaloz

      Love what you wrote and I have been taking them for only one week and its awful.Headaches and after first few days appetite actually increased and frequent urination, and I am not drinking any caffeinated drinks so I thought it strange that I would have to urinate so often , also extreme fatigue / weakness can hardly do house chores or drive..Flue like symptoms for sure with rapid heart palpitations …Well the old way is the best way , exercise and eating right !!!

      • Fay Council

        I hope you’re okay, I ended up having a heart attack. GET CHECKEDOUT

  • Liam

    Been taking 3 a day for two and a half weeks. No side effects, but pretty decent results. I’ve lost about of my belly fat (and about 8 pounds), sleep like a baby and feel great! Mind you I’ve made some lifestyle changes. NO alcohol, balanced high protein diet and a half hour a day of a tread mill. It seems to be working great. Sorry to those who had a bad experience, but keep with diet and exercise any way.

  • C. Black

    I’ve tried all kinds of diet supplements. When the new GC came out I was excited to try it! I used it for 3 weeks and than i started getting sharp pain in my head, I’m tired all the time. I can’t sleep..I feel drained out so I stopped using it. Natural dieting and exercises is the best and safe way to loosing weight.

  • cherie

    I’ve been taking pure GC. 6 a day (the recommended dose) 200 mg. No head aches or discomfort. No rash. I did poop a lot but seemingly healthy poops. I feel I eat when stressed. So I’m not sure whether my increased hunger is circumstancial or not. I feel lighter and slimmer in just a week. I’ve lost a couple pounds. We’ll see. I believe it will work.

  • sandy

    I started taking garcinia cambogia some time back and had to stop
    because after a few days I become tired and felt kinda depressed.
    Energy level got worse and appetite started to increase so I stopped.
    I started it again yesterday am. Felt less hunger and okay but today
    I had to stop it again. Felt very tired, hungry and down. I do not
    take any anti depressants but have a past history of anxiety. This
    is a warning to those with this problem. Beware !!! I remember a
    doctor told me years ago to stay aware from any herbal pills but I
    had forgotten and wanted to give it a try…..

  • Teresa Kellogg

    Have been taking this for a couple days down a couple no diet change. Exercised on my eliptical twenty min per day.Some cramps..

  • Sherday

    Yes me too with the vomiting ,diarrhea , and chills.. my stomach is so upset not really able to eat …. and when I do only small amounts after I’m done eating I’m back in the restroom

  • yahi

    I’ve been taking CG for two weeks. I have noticed a change on my belly and also the back of my legs. The bottle says 3000mg per day so I take 4 to 6 500mg daily. 1 before bedtime with no food. Now for side effect I’ve been getting slight headaches aside from my migraines. Ive been getting Migraines since I was a kid, so it might sound crazy but I tell that the CG is adding the extra. On my second week, at like around four in the morning, I started getting nausea it was bad but I figured it was because I wasnt drinking as much water. Its been three days and I still feeling the same just not as bad. I’m going to start taking the CG again, now that I let my body rest a little but this time I’m going to drink lot and lots of water… Lol

  • Sofia

    I have been taking Garcinia Cambogia for over a week now almost 2 and I have not lost any weight. However, on the bottle it advises to use 2 pills 1 – 2 hours before meals for weight loss and 1 pill 1 – 2 hours before meals for satiety dosage. My interest was not to lose weight but surpress my appetite or control my cravings. I have noticed I am kind of “bloated” and yes gas-y. I am assuming this is normal as fruit can do this to me.

    Another thing I also noticed is that I only eat 1 core meal a day and for the remainder of my day I may eat a banana or a cheese strings (that’s all!). Anyone else experience the same?

    I would still recommend this product to many people; but first consult a professional about your health.

    Thanks.

  • Be

    I experienced no weight loss. Took this supplement for 3-4 months. Recently I’ve gained weight. I cannot lose it and now I’m hungry all the time. Not sure if stopping will make it worse. I think it hurt my metabolism some how.

    • Fay Council

      When I was admitted in the hospital, I had little to no metabolism. Get checked out..

  • Andi

    I’ve been on GC for 1.5 weeks. The last few days I have been experiencing a mild to moderate headache, tension in my neck, lack of energy, and for a few hours after I take a dose, I feel “cracked out”. I seem to be more irritable too. I am drinking plenty of water and getting adequate sleep. I thought I was experiencing eye strain, but I have taken all of the necessary precautions to avoid that. I’m stopping this drug today. I’m an RN, and know better than to stay on it with these symptoms.

  • Leslie

    I been taking GC for a week i have been going through it I have heart palpitations,anxiety ,caugh,stomach cramps and headaches I’ve been of the pill for 2days and still exsperiencing side affects hope it go away soon

    • Fay Council

      You may want to check those heart palpitations it. I had them too and I had a heart attack. Please check it out!!!!

  • Amber

    I had only taken GC for 3 days (2 a day). I felt pretty wired on them but it was tolerable. On the 4th day I hadn’t taken one before work and an hour into my shift out of nowhere I suddenly felt extremely emotional to the point of bursting into tears and I was having a panic attack, it took an hour until I was able to calm myself down. I knew immediately it must’ve been due to the effect GC has on seratonin. I decided that day to stop taking them. This was over 10 days ago and I’m still experiencing anxiety attacks and feel like I have the flu. My symptoms are that of SSRI withdrawal. I do have a history of mild anxiety and depression so I would strongly urge people with those issues to NOT TAKE THESE PILLS. I’m very scared I’ll never get back to normal as it’s been over a week and no signs of any change. It’s just shocking to me because I had only taken it a few days.

    • Lindsay

      Don’t worry, it will go away. I have similar problems, and I can see after 2 days that these pills are no good for me! Don’t psyche yourself out though, you’ll get better!

  • Ana

    I started these 15 days ago. Using the GNC ones. The first week was ok, but after the second week, I began to feel nauseous. Yesterday I started to vomit, it has been really bad. It feels like there is something stuck in my throat and I have read that it can sometimes cause throat inflammation which is probably what I have.
    I stopped them immediately after the vomiting began. However a day later, I am still vomiting every couple of hours. Have no appetite at all & I feel listless, have no energy whatsoever, feel depressed and am afraid that I may have damaged my liver.
    Please do not take these pills.

  • Cam

    I just took my first garcinia cambogia pill today (about 10:15a) by 10:45a, I had a terrible stomach pains in the core of my abdomen. I then ran to the bathroom thinking that my breakfast may have caused the reaction (which by the way was one egg and one piece of wheat toast) but when I finished, i suddenly had to vomit. I have been in the bed, trying to recoup. I’ve never had a reaction like that with any diet pill I’ve ever used. I’m done with these pills.

  • Sabrina

    I started taking these just after new years (I thought they could be a resolution cheat). After about a week, I was feeling totally drained and dizzy all the time, but I was seeing some amazing results, so I just reduced the dose a little and kept taking them. About four days into the second week I was in the shower and fainted. Luckily, I didn’t injure myself, but I did stop taking them immediately. About a week after stopping with GC, I started to feel more energetic and normal again. Don’t take these; they’re a mess.

  • suelynn

    For the many people having side affects, you may be allergic, sensitive to the high dosage, not eating/exercising, possibly just detoxing, or taking more than you should etc. So far I’ve been feeling great! I’ve just been hungry…but for healthy food! I look at packaged or junk food and I feel like I want to just vomit. Yet when I look at veggies, fruits, or whole grains I get this craving for it. Very odd!Even WATER!!

  • Sarah

    Thanks so much for all the input! I have been researching and trying to see which brand to buy and also whether or not these capsules had any side effects whatsoever but couldn’t find anything. There are a lot of mix reviews on here so my only question is what brands did you guys purchase? Cause there are lots of cheap and fake ones out there and which brand is the best?

  • rob

    Don’t work, period!

  • Lucylu

    I’ve been taking this for two weeks my energy levels are great but my hunger increased since day one now I’m 5lbs heavier and eating like crazy

  • Maria

    I just started 2 days ago and I’m having a stomach upset and pain,and makes me hungry so I guess I have to stop.

  • Autumn

    I’ve been taking the Garcina in the form of NOW brand Super Citrimax. I’ve been taking it for six weeks and I’ve lost 14 lbs so far. I have been taking two capsules an hour before each meal and it has literally stopped all my cravings. I was such a sugaraholic prior to trying the Garcina and now, no cravings for any kind of junk food at all. NONE! Plus, it controls my appetite like you would not believe. I have to remember to eat now. I am rarely ever hungry any more, which makes it’s real easy to make healthier choices when I do eat. I did experience some constipation after a few weeks but drinking extra water seems to have fixed that. I can hardly believe the results I’m seeing. I am 56 yrs old and have osteoarthritis in my knees and spine, so I’m not able to exercise daily. All I have been able to do is take this supplement and hope for the best so that I can lose enough weight to begin exercising again.

  • gillian

    Been taking Garcinia 50pc HCA for 4 days. Experienced headaches and severe constipation. Also makes me hungry yet I have previously not been having food cravings since I have been on a low carbon diet. After reading these comments I am throwing my bottle of garcinia into the Bin!

  • Lesley gascoyne

    I took one of these capsules on a Monday, I started having light cramps which rapidly increased to excruciating pain, nausea, sweating and diarrhea. I have only taken the one pill and I’m on day 4 of not being able to eat anything. Ofcorse I have lost 4 lbs in 4 days but this is not healthy. Going to have my liver enzymes checked. Please don’t take this product!

    • Fay Council

      How are you feeling now?

  • Lindsay

    Wow, I’m glad I found this page! Finally some answers. I got the Garcinia (green bottle) the one that is “just pay for shipping”. I took it for 2 days and had a lot of diarrhea, fatigue and worst of all irritable! This stuff is as we say in San Diego, NO BUENO!

    • Fay Council

      Please be careful, don’t allow it to do to you, what it done to me.

  • Fay Council

    I took the GC to lose weight for a church event. After taking them for a few days, I noticed I started itching on my back and my husband noticed these bumps everywhere on my back, i was having really bad sweats, real bad cramps and I also started having heart palpitations. I even noticed that my mobility in my body had decreased to the point to where I began to crawl up the stairs. Of course by now, I had stopped taking the pills. This was in March, 2013. In July,2013 I went to ER because of the bumps and found out that I had had a heart attack. I ended up having a double by pass. I am a 50 yr old and had no prior health problems. Please beware.

  • Jane Jensen Mazurs

    I started taking the suggested dose of the capsules for one bottle and saw no weight loss. I then took 2 capsules 2 times a day and developed a rash/redness in the urinary area, but I then lost weight 5 lbs in a week. Although i haven’t been drinking enough water. I’m going to try drinking more water and go back to the recommended directions, to see if the rash improves. I think my urine is concentrated with the fruit acid and causing my urinary area discomfort.

  • Maggie

    I’ve been taking GC for about 3 weeks and started getting the bumps and itching right away on my back. It did not occur to me what was causing it. I’ve been very emotional, as well.

  • Aimee

    I started taking them a few days ago and I cannot stop eating, its non stop i eat then im still hungry. I suppose itl put on weight and il have to stop :( ha

  • Wilkinsons

    I’ve been taking Garcinia Max 3500g now for 4 days (today will be my 5th day), recommended dosage is 3 per day. I’ve had no side-effects. I have insomnia and had restless nights every night but have been sleeping very well since taking these capsule although I have changed my diet and now have a fitness regime. I never exercised and I ‘was’ a stress eater. The same day I started taking these capsules I purchased a Fitbit Flex, which I keep on my wrist 24/7, which tracks my sleeping habits, my calorie intake, my steps, my water intake and much more. In the last 4 days I have lost 2kgs while eating healthy, I feel great and have more energy

  • dee1980

    Before these pills I was a very active person. Ran everyday. Watched what I ate. I only took these pills 1x a day for a week. So far all I do is eat. To a point where I cant stop. My body feels gross. Im so completely exausted to a point where my eyes are closing by themselves. Yesterday. I went to breakfast. Got home and I felt like someone was drilling holes into both sides of my stomach. I swear I could have rolled over and died. Im so tossing these. Worst mistake of my life.

  • Cesare

    Hi, yes I have used for few days and I ended in ambulance because I fainted on the train on my way back from the city. I stopped taking them, but after a week I thought that the cause could be something also and I had one more, result I was shopping and I fainted again. (Back in an ambulance)
    I though I was wrong about the GC and a month after I had one more, result I ended in emergence hospital because I fainted again.
    Could not believe how this tablets can be sold in the market when people are having to risk that much.
    They should be taken out from the market.
