Hey Dan! Yeah vivid dreams are actually pretty common with B12, especially if you take it before bed. It can mess with your sleep cycles a bit. Try taking it in the morning with food. And the bright pee is just your body flushing out excess riboflavin (B2) if it's a complex, or sometimes just the dye in the gummy. Totally harmless. How much are you taking?

I've been taking B12 for years (I'm plant-based) and I get the wild dreams too if I take it too late. I usually pop mine after my morning yoga session. Also, stay hydrated! That neon pee is just your kidneys doing their job. Nothing to worry about, but maybe check the dosage. Some gummies are like 1000mcg which is overkill unless you're deficient.

Omg I thought I was the only one! I started putting my B12 gummies in my morning smoothie and the dreams chilled out. But yeah, the first week I had some crazy ones. Also, have you noticed any change in taste? I swear my coffee tasted weird for a few days. Could be unrelated tho. Anyway, you're not alone!
