Experiencing nausea after taking Centrum multivitamins is not uncommon, and it can happen for several reasons. Your symptoms, including intense nausea, headaches, and a strong urge to vomit, may be linked to how your body reacts to the ingredients in the multivitamins.
Explanation
- Stomach Irritation: Some multivitamins contain iron or other minerals that can irritate the stomach lining, especially when taken on an empty stomach. This irritation can lead to nausea and discomfort.
- Dosage Sensitivity: High doses of vitamins or minerals—such as vitamin A or calcium—can also cause nausea if your body is not accustomed to them.
- Food Interactions: Taking multivitamins without food can exacerbate these effects. Consuming food after taking the vitamins seems to alleviate your discomfort, indicating that taking them with food may help.
- Allergic Reactions: Although less common, it’s possible to have a mild allergic reaction to one or more ingredients in the multivitamins.
Next Steps
-
Take with Food: Always take your Centrum multivitamins with a meal. This can help reduce irritation and nausea.
-
Hydration: Ensure you stay well-hydrated before and after taking your vitamins, as dehydration can worsen nausea.
-
Monitor Dosage: Consider whether the dosage of certain vitamins may be too high for you. If this continues, look for a different formulation or a multivitamin with lower doses.
-
Document Symptoms: Keep a diary of your symptoms related to multivitamin use. Note the timing, severity, and any other symptoms you experience to see if there are specific patterns.
-
Change Formulation: If issues persist despite these changes, consider switching to a different brand or type of multivitamin, such as those specifically designed to be gentler on the stomach.
If you continue to experience severe nausea, headaches, or any other concerning symptoms, it may be useful to further investigate potential allergies or sensitivities.

Navigating the Challenges of a Manipulative Supervisor
Hello everyone, I'm currently experiencing a challenging situation at work and would greatly appreciate any insights or words of encouragement from those who can relate. My supervisor exhibits toxic behaviors and is highly manipulative. She tends to imitate my personality and concepts, presenting them as if they originated from her. While she plays the innocent and naïve role in front of others, she consistently undermines me behind the curtains. Moreover, she attempts to exert control over my social interactions. For instance, she reacts with jealousy whenever I engage with male coworkers or forge new friendships. She interrupts conversations and even spreads false narratives about me. She seems to have adopted a maternal-like demeanor, frequently “guiding” me in a condescending manner, but her interference distracts me from my actual objectives, such as preparing for exams or considering a career change, leaving me feeling inadequate. Additionally, her physical boundaries are invasive; she touches me in ways that are uncomfortable, and she keeps tabs on me and my friends through social media. She seems to create rifts between me and my peers, leaving me feeling emotionally and mentally drained. I also resonate with the idea of the “evil eye” and have observed peculiar occurrences since I confided in her about my life. As an introvert (INTJ), I struggle to connect with my colleagues, and her public ridicule regarding my attempts at socializing only compounds this difficulty. I am seeking advice on several matters: - What strategies can I employ to establish boundaries with a manipulative superior who holds power in the workplace? - How can I safeguard my emotional, mental, and spiritual well-being while remaining employed here? - Have any of you encountered a similar scenario with a toxic manager? What methods were effective for you? - Any suggestions for managing disingenuous friendships and the issue of identity theft in the workplace? Thank you for taking the time to read my post. I truly value any support or guidance you can offer. **Summary:** My supervisor emulates my personality and ideas, controls my social interactions, invades my personal space, and pretends to be a supportive friend while consistently undermining me. I'm finding it difficult to set boundaries due to her authority over me. I'm looking for advice on managing toxic supervisors, shielding myself emotionally and spiritually, and navigating fake friendships and jealousy in the work environment.
Understanding My Ear Troubles
I'm a 28-year-old male, standing at 5 feet 10 inches and weighing around 240 pounds. I don’t smoke and enjoy a drink occasionally. Lately, I've been experiencing discomfort in my left ear. It has been itching and hurting over the past few days, and now it feels extremely congested. There is definitely some swelling present. I took a look inside with a camera and noticed some bumps. I’ll share the details in the comments for further discussion.
Red Mark on the Top of My Foot
- Age: 23 - Gender: Male - Height: 5'10" - Weight: 199 lbs - Currently taking dicyclomine and atenolol as necessary for IBS and POTS. I've noticed a peculiar red line or mark on the upper part of my right foot that has persisted for the past 2-3 days. I can't show a picture since I'm unsure how to upload one here, but I'm seeking some advice. To give a bit of background, I tend to be anxious about my health, which isn't ideal. I’ve been diagnosed with both IBS and POTS, and flare-ups from these conditions are quite distressing. A few days ago, I got out of bed and spotted this red streak on my foot. It's neither too small nor overly large—just a subtle but observable mark. When I play video games while seated, the color seems to fade to a lighter pink shade, which is a bit relieving. However, I have recently begun to feel soreness in that area. For additional context, I had been feeling unwell for over a week leading up to this mark’s appearance, spending most of that time resting in bed and only getting up for essentials. The mark has not visibly increased in size from what I can tell, though it remains present. I have been wearing compression socks throughout the day; upon removing them, I noticed the redness diminished somewhat. Does anyone have any insights or ideas regarding this situation?
Unexplained Muscle Strain Symptoms
Hello, I’m an 18-year-old female and recently received a diagnosis of IBS, although I feel this may not be connected to my current situation. In the last week, I’ve somehow managed to strain my back, calf, and chest muscles, and notably, I haven’t engaged in any heavy lifting or sustained an injury. This leads me to wonder how multiple muscle strains can occur without a clear cause. For the past couple of months, I’ve experienced muscle spasms, weakness, and various systemic symptoms throughout my body. My healthcare providers seem inclined to attribute this to IBS, but I find it hard to believe that digestive issues would manifest in muscle strain, as it seems illogical. I am open to providing more details if necessary.
Experiencing Episodes of Distraction and Involuntary Movements
Profile: 22 years old, height 6’1", weight 65.7 kg. Lifestyle: Non-smoker, abstains from alcohol, not on any pharmaceuticals, and has a mild case of scoliosis. For approximately the last six months, I've encountered an unusual phenomenon that manifests several times a day, around 10 to 20 instances, where I zone out for a brief period lasting between 5 to 10 seconds. During these moments, I also find myself blinking repeatedly, often followed by involuntary twitching in my legs or my neck and head. Both the blinking and twitching occur without my conscious control; I am aware of what’s happening, yet I am unable to prevent my eyes from blinking or to focus them, nor can I inhibit the movements of my head. Initially, I chose to overlook these occurrences, but a few individuals have started to notice and comment on them, creating a rather uncomfortable social situation for me. Additionally, I have experienced two spontaneous full-body convulsions, during which I ended up biting my tongue and sustaining some bruises—once in March while running, and another time in June, in the middle of the night. After each episode, I felt perfectly fine and did not seek medical attention. Despite some concern about these symptoms escalating, I'm uncertain whether consulting a healthcare professional is warranted at this stage. The episodes of zoning out and involuntary blinking are becoming more troublesome. I have undergone thorough cardiac assessments previously, especially given my family’s medical history of heart-related conditions, and have been cleared from any cardiac issues as of February.
