Concern About Long-term Prenatal Vitamin Use: Is It Safe?
I am a 26-year-old woman weighing 180 pounds and standing 5 feet 4 inches tall. I do not use any drugs or substances, relying solely on prenatal vitamins for supplementation, and occasionally I incorporate a probiotic. For the past two years, I have been taking prenatal vitamins. My journey has been challenging, having experienced two miscarriages—one in September 2024 and another in January of this year. In my quest to conceive, medical professionals have consistently advised that I should start taking prenatals at least three months before trying to get pregnant. This advice has influenced my long-term use of these supplements. I am aware that excessive intake of vitamins can lead to toxicity, and my primary concern is whether continuing to take these supplements is safe for me. Overall, I consider myself to be quite healthy, aside from needing to incorporate more exercise into my routine. When I had blood tests done last January, the results were normal, and I had paused my vitamin intake at that time. Now, I am looking for a second opinion, as I find that online resources often lack clarity on this issue.

It's understandable to have concerns about the long-term use of prenatal vitamins, especially considering your desire to conceive and your previous experiences with miscarriages. It's important to ensure that you are supporting your health appropriately while being mindful of the potential for over-supplementation.
Main Points:
- Prenatal vitamins are generally safe and beneficial as they provide essential nutrients needed for pregnancy planning and fetal development.
- Long-term use can be safe, but caution is necessary to avoid excessive intake of certain vitamins and minerals.
Explanation
Prenatal vitamins are designed to support pregnancy by providing nutrients like folic acid, iron, and calcium, which are crucial for developing a healthy baby. They are especially recommended before conception and during pregnancy to reduce the risk of neural tube defects and other issues.
However, taking prenatal vitamins for an extended period, particularly when not actively trying to conceive, can raise some concerns about nutrient excess. For example, while folic acid is safe in recommended amounts, excessive vitamin A (found in some prenatal vitamins) can be teratogenic (harmful to fetal development).
Next Steps
-
Assess Your Prenatal Vitamin: Check the ingredient labels for your prenatal vitamins to confirm their dosages, especially for vitamins A and D, as well as iron. Ideally, the amount of these should align with recommended values.
-
Consider Nutrition: Focus on a balanced diet that includes a variety of fruits, vegetables, whole grains, and lean proteins. This can help provide many of the nutrients you need without excessive supplementation.
-
Monitor Your Body: Since you had normal blood test results in January, consider getting another blood test to see if you have any deficiencies and to monitor your vitamin levels. This can guide your continued use of prenatal vitamins.
-
Evaluate Your Usage: If you are not actively trying to conceive at this moment, consider discussing with your healthcare provider whether continuing prenatal vitamins is necessary or if a standard multivitamin might be a better choice until you prepare for pregnancy again.
-
Stay Active: As a side note, gradually increasing your physical activity can improve your overall health and well-being. Even gentle activities like walking can be beneficial.

Privacy in Health Records for Alberta Teens: Navigating Birth Control Access
I am a 15-year-old girl, seeking guidance on how to obtain birth control without involving my parents. I created this new account for privacy reasons since my regular profile includes my personal details. I have some questions regarding the process of acquiring the pill in Alberta. I apologize if I am posting in the wrong forum, but it appears that r/Alberta restricts new users from posting. For a while, I've been considering starting birth control. Thankfully, I haven’t taken the step yet, but being 15 years old, I want to ensure I handle this correctly. My plan was to visit a local clinic after school to obtain a prescription and then fill it at a nearby pharmacy. Now, I’m anxious that if I receive this prescription, it will appear in my Alberta health account, potentially alerting my parents since they could see it just like my other prescriptions. Does anyone have suggestions on how I might discreetly approach this? Alternatively, I'm considering an IUD since it could provide a longer-term solution if I can find a way to get it inserted. Is it possible to order it online or perhaps ask a friend to help me, even if it's not entirely secure? I don’t mean to delve into a political discussion here, but it seems unfair that confidentiality can be compromised so easily!
Understanding Bilateral Adrenalectomy
Hello! I’m a 30-year-old female who has recently been diagnosed with Cushing’s disease after a thorough evaluation. My diagnosis followed a series of tests, including morning cortisol levels, ACTH testing, late-night saliva tests, a 24-hour urine analysis, IPSS, and a desmopressin stimulation assessment, all conducted by my endocrinologist. Despite undergoing two surgeries on my pituitary gland, my cortisol levels continue to be elevated. Unfortunately, due to other underlying health conditions, I cannot take medication, which leaves me with the option of a bilateral adrenalectomy. I have an appointment with a surgeon coming up soon. What should I anticipate regarding the procedure? Are there specific questions I should pose to my surgeon or ways to prepare myself? I am feeling quite anxious about this surgery, but I realize that I cannot continue to endure this situation. I feel exhausted, and Cushing's disease has severely impacted my overall well-being. I appreciate any insights you may offer.
Inquiry About Conception Timing
The child arrived on January 19. Throughout the course of the pregnancy, several ultrasounds were conducted, which regularly confirmed the gestational age with measurements taken at 25 weeks, 32 weeks, and 36 weeks on various occasions. These assessments led medical professionals to approximate the ovulation and fertility period between April 8 and April 17. It is well known that sperm can last in the female reproductive tract for about five days. Notably, intercourse took place on April 26, a date that falls beyond the predicted fertile period. Considering the ultrasound results and standard ovulation patterns, could April 26 reasonably be identified as a possible date for conception?
Chest Discomfort with Red Marks
Over the past year, I have developed red patches predominantly on my upper chest and occasionally on my neck. My physician suspects that this could be linked to anxiety. These marks often become painful upon contact and sometimes provoke an itch. Although I’m uncertain if it’s connected, I also experience occasional discomfort in my chest, particularly around the sternum and collarbone areas. I’m concerned that there might be a misdiagnosis and that an underlying issue could be present. Has anyone else faced a similar situation or discovered the underlying cause of their symptoms? I’m a 24-year-old male who does not smoke, consume alcohol, or use drugs.
Is it Safe to Reintroduce Birth Control After a Smoking Break?
A 45-year-old woman has recently quit smoking after a 7-month period during which she also took Effexor. Due to the combination of medication and smoking, she decided to halt her hormonal birth control along with Effexor. Now, with a month of being smoke-free and currently taking Wellbutrin and Vyvanse, she feels confident about her progress and is contemplating resuming her birth control pills, specifically Seasonale. Her medical history reveals no complications such as blood clots, and her doctor initially approved her to restart the medication. However, after further consideration, the physician sought the opinion of an ObGyn for confirmation. The woman is eagerly awaiting feedback from the specialist, ideally before she intends to begin her birth control again this coming Sunday, which coincides with the start of her menstrual cycle. Since Seasonale is designed for extended use, this will already lead to postponing her period by three months, and any delay in resuming the pill could extend that timeline further by another 3.5 months. She notes that the mini-pill may not effectively assist with managing her PMS cravings, making it an unfavorable choice. The woman is reaching out for guidance on the appropriate course of action. Any insights would be greatly appreciated!
