    At age 68-my workout regimen requires the absolute best supplements

    Naomi does a great job sourcing the best supplements in combination with the right ingredients without adding peripheral low end fillers to help sell her products. This is key for someone like me who tracks his health based not only on a workout plan but also by my daily nutrition. I use her magnesium bergamot daily.

    Mighty mg

    I used to have muscle cramps in my legs. They were very painful. Since using mighty MG I no longer feel apprehensive when I go to bed and wake up worrying if I am going to have leg cramps.

    Feel the effects!

    I purchased this product based on the information provided and the reviews of others. I have trouble sleeping sometimes and itching around my ankles and feet due to diabetic peripheral neuropathy. The Magnesium Glycinate calms all that down and I sleep much better, and longer, and have less itchiness. I will add that I do apply particular herbal balms on my skin as well and that helps a lot, too. Thank you for creating this product!!
