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!

Experiencing Premature White Hair as a Teen
Hello everyone, I'm a 17-year-old female and I'm not entirely sure where to share my thoughts, but I've observed something concerning lately: I've started to notice several strands of white hair on my head. What's strange is that not all of these hairs are completely white at the roots; instead, they've turned white somewhere in the middle. I've been feeling under the weather for a while, and I can't help but wonder if this could be an indication of a possible vitamin deficiency or some other issue. I'm genuinely confused because every time I check my hair, I seem to find more white strands 😭. My hair typically starts off brown at the roots, but then it transitions to white halfway down, and toward the tips, it goes back to brown again. It's definitely not gray hair, but pure white. I'm unsure about what this might imply, and it’s really concerning me. 🤔
What Could These Bumps Be?
I’m a 28-year-old female and I’m not currently taking any medication. Recently, I’ve noticed numerous skin-colored bumps appearing on my arms, back, neck, and ears. These lesions are quite itchy and have a prickly sensation, giving my skin an appearance reminiscent of a cactus. I’ll share a photo in the comments for reference.
Seeking Guidance for Ongoing Health Issues
I’m a 23-year-old man, standing at 5'10" and weighing 173 pounds. My health struggles have led me to consult dermatologists, primary care doctors, and urologists. Recent blood tests revealed elevated AST and ALT levels, though all other results fell within normal limits. These liver enzyme abnormalities might be linked to medication I took for prostatitis, but despite this treatment, I continue to endure symptoms resembling a urinary tract infection. To further investigate, I underwent a liver ultrasound, which returned normal results. Currently, I'm dealing with unsettling sensations in my legs and feet, especially in my right leg, where I frequently feel tingling that fluctuates between numbness and discomfort. Additionally, there is an odd feeling in the front of my right shin, and I have recently noticed the appearance of small, painless pits on that leg. These marks look bruised and scar-like, yet there are no open wounds—one is positioned on my shin near the numb area, while three others are located on my thigh. Joint discomfort has also become an issue, accompanied by strange discoloration on my ankles, which resembles faint bruises running along the top and sides. I often experience sharp, sporadic pain throughout my body, affecting my upper arms, thighs, and abdomen, as well as a distinct pain radiating from my right testicle to my lower ribcage. I live in constant fear that my condition may signal a serious degenerative issue involving my veins, blood, nerves, bones, or muscles. With a family history of autoimmune diseases, I can’t help but worry that I might be facing one myself. The persistent pain, neuropathy, and unusual marks on my skin have me terrified. I’m willing to share additional blood work results and medical records if needed, but I am reaching out in hopes that someone might offer insight into what could be affecting my health. I would greatly appreciate any advice or information you could provide. 🥺
Challenges with Vitamin D and Iron Absorption
In early 2024, at the age of 23, I underwent my first comprehensive blood test as an adult and discovered that I was low in both vitamin D and iron. In response, I began a regimen of supplements, taking 10,000 IU of vitamin D and 65 mg of iron daily, although I occasionally missed some doses. I ensured to take my vitamin D with meals and paired my iron intake with vitamin C to enhance absorption. Fast forward a year when I had another blood test done. To my surprise, the results indicated that my levels remained largely unchanged, with ferritin at 51 and vitamin D at 45. I am pretty sure my iron levels stayed the same while my vitamin D may have actually decreased. Additionally, I was diagnosed with hypothyroidism earlier in 2024 and have been managing it with NP thyroid medication. This makes me wonder about the underlying issue. Despite my consistent supplementation, why aren't these vitamins being absorbed properly? Could this indicate an underlying gastrointestinal issue? What steps can be taken to resolve this?
What Could This Be? Should I Visit My Doctor?
Hello everyone, I would truly value your thoughts on an issue I'm experiencing. Some days ago, I discovered a dark bump on the side of my heel that has become quite tender while walking. I can't recall any incident where I might have injured my foot or stepped on anything. This bump wasn't present a week prior. Today, the size of the bump appears to have increased, and there's a bit more discomfort, yet I am still able to walk without any major issues. It's definitely not a blister, as I have already tested it with a sterile needle, and there was no fluid or blood. I hesitate to reach out to my doctor if this isn't something to be overly concerned about. I intended to share some pictures, but I’ve realized that the link doesn't function, so I’ll post the images in the comments section shortly. A little about myself: - Age: 26, Female, Caucasian - Weight: 52.3 kg, Height: 172 cm - No significant medical history - Former smoker - quit four years ago; currently, I use nicotine vapes - I occasionally take ibuprofen, but it’s been weeks since my last dose; no other medications or supplements in my routine Not sure if this is pertinent, but I have tested positive for HPV twice and plan to have follow-up checks next year.
