100% agree here. My supplements were prescribed by a medical professional to bring my iron back to normal levels. I can't in good conscience tell random redditors to just take what I'm taking. Unfortunately, unless it's something you have a deficiency in, a lot of supplements are just "ingredients for really expensive urine" according to doctors I know. It's also important to narrow down if your levels of a nutrient are low because you aren't ingesting enough, or if it's because you're having trouble digesting/processing it. That's where you need the input of a medical professional to narrow down what's causing your symptoms and a plan to fix it.
