After I recovered from COVID, I had tremendous hair loss. It was the kind of hair loss you would see from chemo. I was also struggling with brain fog. After speaking with my provider, he suggested that I take a good B-Complex. I stopped in a health food store while on vacation and there was a kind man that was full of good advice and told me to start with this particular B-Complex because of how it is made and how it works. I am sorry that I don't remember the details. Anyway, he told me if this didn't work to try another brand because all bodies are different. The most important thing was to take these on an empty stomach and wait for 2 hours before eating and to take in the morning. He schooled me on how a B-Complex works. He told me that if the vitamin was working, I should get a small boost of energy. That is why it is taken in the morning as it will keep you awake, or from sleeping well, if taken before bed. He also told me that if it upset my stomach take only one at a time rather than two. I did start with one at a time but shortly moved to two at a time in the mornings and I have no problems even though I have a more that delicate stomach.
After about 2 weeks I had completely stopped losing my hair. After about 3 weeks I noticed little sprigs of hair growing back. I wish I had before and after photos. My once widened part is now all filled back in. I couldn't be happier. Along with that, my brain fog has lifted, and I am once again able to beat or tie my husband in a strategy game we play. I highly recommend this brand.
