I found these postpartum (unfortunately), but started when I was still breastfeeding. Ever since I started these vitamins (about a year ago? Maybe longer?), I noticed a big shift in my energy. I feel more alert and ready for the day. My sleep has also improved thanks to the magnesium (and having more energy for activity and exercise). Even though I’m no longer breastfeeding (and because you never know when a pregnancy might happen), I’m still taking these to supplement my diet. I often try to get what I need from real foods, I haven’t always been a fan of supplements, so just to see if I would notice a difference, I went off of them for about a week— and, yes, I definitely noticed I felt more sluggish and tired. As soon as I started them up again, my body felt it had what it needed once more and my energy perked up immediately. It’s unfortunate that the nutrient depletion in the soil these days can even effect the nutrients we’re hoping to receive from whole, organic foods. But I guess that’s just the world we live in right now, and I’m thankful these multi-vitamins exist to supplement what I need!
