I tried many supplements for years. B12 was always the biggest as a vegan, sometimes iron - but I got that under control through food and better focus on it. But now, as I passed the 35 years, the body is working differently. My brother brought me a mix of magnesium, VitK and VitD, and within a week I felt a huge different in my energy level.

Most likely culprit of me being overly tired before? Yes, stress, too, but mostly Vitamin D. In freaking Ecuador. As a white guy who is outside quite a bit. I couldn't believe it, but apparently it's not so uncommon.

Every body is different. There are no rules in nutrition, nothing is super certain. I'm glad you found your way, especially with that dang disease.
