Is It Safe to Continue Monthly Vitamin D Supplements at a Dosage of 50,000 IU?
Approximately six weeks ago, I was advised to supplement with 50,000 IU of vitamin D due to a deficiency I had, measuring at 12.6 ng/ml. Now that six weeks have passed, I suspect my vitamin D levels may have returned to a normal range. Is it advisable for me to continue taking the 50,000 IU dosage on a monthly basis to sustain these levels? I am a 20-year-old male, weighing 52 kg and standing at 160 cm tall. I do not smoke.

It's great to hear that you've been proactive about addressing your vitamin D deficiency. Your question regarding the safety of continuing a high dosage of vitamin D is important for maintaining your health.
Main Points:
- Continuing 50,000 IU of vitamin D monthly may be unnecessary if your levels are now normal.
- Long-term high dosages can lead to excessive vitamin D, which could be harmful.
- It's essential to check your current vitamin D levels before deciding on future supplementation.
Explanation:
Vitamin D is crucial for bone health, immune function, and overall well-being. You started with a deficiency of 12.6 ng/ml, which is below the normal range (generally considered to be around 20-50 ng/ml, depending on sources). A common strategy for treating deficiency is to use high doses initially, as prescribed, but once your levels return to normal, maintenance doses are usually lower.
Taking 50,000 IU monthly is a treatment dose and not typically a maintenance dose. The maintenance amount for many individuals is often in the range of 1,000 to 2,000 IU per day or 10,000 IU monthly, but this can vary based on individual needs, lifestyle, and the advice of your healthcare provider.
Next Steps:
- Check Your Vitamin D Levels: Schedule a blood test to measure your current vitamin D levels. This is the best way to understand if you need to continue, reduce, or stop supplementation.
- Consider Maintenance Dosing: If your levels are within the normal range, ask your healthcare provider about transitioning to a lower maintenance dose of vitamin D based on your specific needs.
- Be Mindful of Symptoms: Watch for any signs of excessive vitamin D, such as nausea, vomiting, weakness, or frequent urination. If you experience any of these, let your healthcare provider know.
By monitoring your levels and adjusting your dosage appropriately, you can support your ongoing health without running the risk of excess supplementation. Let me know if you have more questions!

Pushing Boundaries or Overdoing It?
For several years, I was an active competitive cheerleader, which meant my body was constantly in motion and often sore due to rigorous practice sessions, especially during competition periods. When I transitioned to college and stepped away from cheerleading, I paused my workout routine. This hiatus led to feelings of guilt over my inactivity and sparked a desire to shed some pounds. Consequently, I began monitoring my food intake, utilizing a scale to track my macronutrients. I focused on increasing my protein consumption, something I previously struggled with due to my picky eating habits regarding meat. Around the same time, one of my roommates was dealing with disordered eating, which influenced my own mindset and behaviors, pulling me into a similar downward spiral. During a difficult couple of months, my eating habits fluctuated between consuming limited meals and intermittent fasting. Ultimately, I managed to break free from that harmful cycle and began to enjoy healthier, more balanced meals once again. Simultaneously, my sleep schedule was severely lacking, averaging only 3 to 5 hours each night. Post-Thanksgiving holiday, I established a more consistent routine in December, committing to daily workouts to alleviate the guilt and anxiety surrounding food and boost my sense of productivity. My regimen included a 30 to 45-minute workout, a brief stretch, a 20-minute incline walk, along with several local trail walks spanning about 4 to 6 miles. However, this rapid increase in physical activity took a toll on my body. I developed a pump bump on my right heel and suffered from severe Achilles tendinitis in my left ankle, which became so swollen that the tendon was not visible. A visit to the podiatrist revealed the issue stemmed from a bone growth at the front of my ankle joint, potentially a remnant of a previous cheer injury. I was advised to switch to shoes with a higher heel, take anti-inflammatory medication, and engage in physical therapy. Though the swelling subsided and the pain lessened in the interim, I was eager to get back to college and get into my fitness routine. Upon returning, feeling as though I had fallen behind, I ramped up my workouts significantly. I started a regimen that included an hour of weightlifting followed by over two hours of inclined walking on the treadmill, aiming to burn more than 1,000 calories from Monday through Friday, with weekends reserved primarily for rest, featuring an abdominal workout and leisurely walks. Regrettably, my roommate's calorie tracking habits led me to regress into similar behaviors. I avoided using the food scale this time, hesitant to return to previous unhealthy patterns, yet I still substantially reduced my caloric intake, attempting to keep it below 1,000 calories while burning over that amount through exercise. My approach included moderate meals Monday through Thursday, reserving weekends for larger meals and occasional treats. On weekdays, I typically consumed a third of a banana before workouts, engaged in three hours of intense exercise, then took an energy drink before classes. Post-class, I’d have some cucumber or a piece of fruit before dinner, which generally consisted of protein, a whole-grain English muffin, and salad. If I had room left, I’d enjoy a Greek yogurt for dessert. So far, this strategy has yielded favorable results; I've lost almost 14 pounds since my last checkup in mid-December, and my stomach discomfort has lessened. However, after a 10-mile walk this past Sunday, I began to experience significant pain in my right shin, assuming it might be shin splints but continuing to work out as usual. The week has been challenging, caught between the urge to maintain a 1,000-calorie burn while grappling with persistent pain, even while at rest. The discomfort is concentrated on the front part of my shin, spanning about the size of a quarter, and is painful to touch. Movement aggravates the sensation, making it hurt to walk or even lift my leg while sitting. There's noticeable swelling and warmth, and the pain seems to intensify in the evening, causing discomfort even when resting in bed. I sought care today, and while an X-ray showed no significant issues—a relief—the physician suspects it might be tendonitis. I was initially fearful of a stress fracture, having heard stories of athletes pushing through such injuries, resulting in more severe complications. Given that the X-ray was clear, I am reassured, but I'm still anxious to continue my workouts, as I feel uneasy just remaining inactive and eating without sufficient exercise. I would appreciate any insights into my situation and whether it appears to align with the diagnosis in terms of allowing me to continue training—perhaps avoiding excessive incline walking during this time.
Prolonged Exposure to Magnets: A Query about Safety
Hello everyone, I’m a 26-year-old male and I have a question regarding my work habits. I habitually carried a magnet attached to my hard hat to pick up metal shavings and manage wiring diagrams. Given that these magnets are positioned close to my head, I’m wondering about the safety implications. Are there any research findings related to long-term exposure and potential harm? I can't help but notice that when I carried the magnets, I experienced more intense headaches, though it coincided with the hot summer months, leading me to think dehydration might have played a role. I also do not have any medical implants or serious injuries, apart from a previously torn ACL. I'm intrigued about the matter, particularly since my current magnets are quite weak, and I'm considering upgrading to more powerful ones.
Struggling to Increase My Weight
At 5 feet 7 inches tall and weighing 130 pounds, I’m a 17-year-old male who has been grappling with weight gain for the past year and a half.
