Garcinia Cambogia Side Effects

Garcinia Cambogia is a relatively new entrant in the weight loss supplement field and it gained considerable attention in 2012 when Dr. Oz showered it with accolades. We initially sought reviews on the product back in January, and the response has been quite mixed (at best). Today we’re taking a closer look at some of the known and rumored side effects of garcinia cambogia.

  1. I’ve been on this for 2 weeks and have lost 4kg, not sure of the mg dosage but the bottle says 3500mg and I’m on 2-3 pills a day, but with no prior medical issues am having a number of the side effects listed. My doctor said these side effects are normal, though was concerned about my lack of sleep since starting. But there is an upside to it, I have more energy to chase after my kids.

  2. I started using pure garcinia 2 days ago 1000mg 1to2 a day depending on what i am eating ive noticed that im not hungry at all no noticable side effect other that i shit my life i will continue using it i take raspberry ketone with it as well and a take megnesium pill at night so i sleep verry well

  3. Where can I get this product

  4. 4 days into useing this crap I now have a VERY BAD rash over 95% of my body!!! Lets just say my att. is loving this. Thanks

    I have naseau every morning terrible gas and bloating I think it’s due to this Gambogia carcenea I don’t like it

  8. at first it kept my food cravings under control but now i’m noticing increased appetite.

  9. I started taking GC 3 days ago. Yesterday I felt dizzy and suddenly fainted!!! I stopped taking them.

  10. 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!

  11. 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!! :(

    • 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!!

  12. I have noticed increased bowel irritation/ piles/haemorrhoids

    Does anyone else have these effects?

    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

  15. 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?

  16. 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

  17. 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.

  18. 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.

  19. 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.

      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 !!!

  20. 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.

  21. 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.

  22. 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.

  23. 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…..

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

  25. 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

  26. 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

  27. 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.


  28. 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.

  29. 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.

  30. 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

  31. 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.

  32. 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.

  33. 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.

  34. 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.

  35. 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!!

  36. 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?

  37. Don’t work, period!

  38. 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

  39. 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.

  40. 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.

  41. 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!
