Understanding Vitamin Supplements and Blood Test Results
Greetings! I'm a 20-year-old male and I recently underwent blood tests for the first time. I have a few queries I hope to clarify. My Vitamin D levels, specifically 25 Hydroxy-Cholecalciferol, were measured at 22.92 ng/mL. Additionally, my Vitamin B12 (Cyanocobalamine) comes in at 60 pmol/L. Do I need to speak with a healthcare professional before I start on vitamin supplements? I assumed that supplements could be taken based on personal need, but I’ve heard recommendations suggesting a doctor’s advice is necessary. Also, how frequently should I take them and for what duration? Furthermore, I noticed some other results in my test: - Gamma-Glutamyl-Transpeptidase (GGT) level is 11.82 U/L, - Free Triiodothyronine (T3) stands at 6.35 pmol/L (4.13 pg/mL), - Corrected Serum Calcium is at 9.57 mg/dL. Some of these values seem to fall outside the ideal range, either being too high or too low, and I'm unclear on their significance and what steps I should take next. I've attempted to research these matters, but the information is quite confusing to me.

Thank you for sharing your test results and questions! I can understand how confusing it can be to navigate vitamin levels and their significance. Let’s break down your concerns about your Vitamin D and B12 levels, along with your other test results.
Key Points:
- Vitamin D (22.92 ng/mL) - This level is considered low, and supplementation may be beneficial.
- Vitamin B12 (60 pmol/L) - Your B12 level is on the lower end; supplementation can support your health.
- Other Results - Your GGT, T3, and calcium levels appear to be within normal ranges, which is reassuring.
Explanation:
- Vitamin D: Levels below 30 ng/mL are often seen as insufficient, and 22.92 ng/mL puts you in this category. Vitamin D is important for bone health and overall immune function.
- Vitamin B12: While not critically low, B12 is vital for energy levels, nerve health, and red blood cell production. If levels are low, you may experience fatigue or neurological issues.
- Other Results: Your GGT (11.82 U/L) and corrected serum calcium (9.57 mg/dL) are within typical ranges, which is good news. The T3 level also appears acceptable. However, if you have symptoms or concerns regarding your thyroid, it's worth discussing with a professional.
Next Steps:
-
Consider Supplementation:
- Vitamin D: A common recommendation is 600-800 IU daily, but based on your level, you may need more. Generally, dosage can be tailored, so starting with a higher dose under a professional's guidance may be beneficial.
- Vitamin B12: A typical supplement dosage can range from 1000 mcg (1 mg) daily, especially if dietary intake is low.
-
Keep a Diet Log: Monitor your food intake to see if you might be lacking in vitamin-rich foods (like fatty fish, eggs for D; meat, dairy for B12). This can help discussions with a professional.
-
Consult a Healthcare Professional:
- Although many supplements are available over-the-counter, it's best to consult with a healthcare provider. They can assess your specific needs, ensure there's no underlying condition, and recommend appropriate dosages based on your test results.
- If you experience symptoms like fatigue or mood changes, mention these during your consultation.
-
Follow-Up Testing: Depending on what you and your healthcare professional decide, re-testing vitamin levels after a few months of supplementation can help determine the effectiveness of the treatment.
Taking these steps can help you make informed decisions about your vitamin health and overall wellbeing. If you have any specific symptoms or additional questions, feel free to ask!

Seeking Clarity on Elevated Liver Enzymes Post ER Visits
Hello! I’m a 28-year-old woman (I'll be turning 29 on July 17) and I’m seeking some perspective on my recently increased levels of AST and ALT. This rise in liver enzymes has occurred alongside numerous trips to the emergency room and a recent change in my medication. I'm curious to determine if this condition is merely transitory or indicative of a more serious health concern. **Profile Information:** **Age/Sex:** 28/Female **Height/Weight:** 5’4”, 140 lbs **Smoking Habits:** I occasionally vape disposable e-cigarettes, about once a week, but do not use tobacco or THC. **Alcohol Consumption:** I drink socially; I refrained from alcohol for six days prior to my lab tests, although I have experienced heavier drinking patterns in the last year following the unexpected loss of my mother. **Medication List:** - Adderall XR 20 mg (prescribed, usage is not daily) - Alprazolam 0.5 mg (taken as necessary) In September, during a routine physical, my liver enzymes appeared normal. In late December, I experienced severe pain in my ribs, chest, and back which severely disrupted my sleep. A trip to the ER resulted in a diagnosis of intercostal muscle strain, and my enzyme levels were still normal. In January, my husband had to call an ambulance as the pain persisted; I woke from a nap in excruciating pain that felt as though my ribs were caving in, making breathing difficult. The same diagnosis was given, and I was discharged with steroids, which provided immediate relief. However, liver enzymes at that point were recorded as mildly elevated. Just recently, I faced a similar situation and returned to the ER. Again, I was diagnosed with a pulled back muscle and was sent home with steroids. This time, my blood tests indicated that my AST and ALT levels were elevated once more, and this increase was more significant than before. I have scheduled an appointment with my doctor tomorrow to discuss further blood tests, and until I receive the results, I am committed to abstaining from alcohol and avoiding medications like Tylenol or ibuprofen. **Update:** On both ER visits, the attending physician downplayed the significance of my elevated liver enzyme levels, suggesting they were within an acceptable range. My regular doctor echoed this sentiment following my initial ER follow-up.
Seeking Guidance After My Grandmother's Fall
I’m feeling quite overwhelmed after my grandma fell recently. She's in her 60s to 70s and while exiting the bathroom, she stumbled and fell backwards, striking her head against a concrete wall. After the incident, she sat on the floor and managed to talk to me. I helped her get back on her feet and walked her to her bedroom, where she even took a phone call and chatted normally. Now, I'm unsure about what signs to monitor for her. I must admit, I'm anxious because I fear that something might be seriously wrong. I noticed she had some difficulty walking to her room after the fall. Any advice or assistance would be incredibly appreciated!
Recently Noticed Spot on Breast
Greetings, community. I’m intending to consult a physician shortly regarding an issue I’ve noticed, but I’d appreciate hearing your thoughts in the meantime. There is a small area on my breast that has changed color. It doesn’t have any unusual texture, and though it resembles a bruise in appearance, I assure you it isn't one. The discoloration is merely a bit darker than the surrounding skin. I’m grateful for any insights you might offer!
How Do Performers Bulk Up for Roles Without Developing Diabetes?
Rob McElhenney, known for his role in "It's Always Sunny in Philadelphia," managed to add 55 pounds to his physique by consuming a staggering 5,000 calories daily, including drinking melted ice cream. He mentioned on a talk show that he was downing a gallon, which seems implausible as that would already exceed 5,000 calories. It’s hard to believe anyone could stomach that amount without feeling unwell. Similarly, Christian Bale is well-known for dramatically increasing his body weight by 40 pounds to portray Dick Cheney in the film "Vice." This raises an interesting question: just how quickly can someone develop diabetes when following such extreme diets? Is it possible that the timeline for acquiring diabetes through such lifestyle choices is longer than many assume?
