I purchased 27 different products including: ribose, carnosine, magnesium, zinc, sod, Vit c, r-lipoic acid, resveratrol, nad+, reishi mushroom, omega-3, acetyl-carnitine. I spent more than €800, and I hoped to be able to improve my health and have more physical and mental energy. unfortunately I had to stop taking the products after a few days as they caused large drops in blood pressure (the maximum pressure was around 90mmHg) and drops in blood sugar. Instead of improving my health, all of this worsened it, as with blood pressure and blood sugar so low, I was forced to bed all day with no energy. such contraindications are not mentioned in the product jars. I would add that some products have zero disintegration, as in the feces I always found entire capsule-shaped lumps expelled without having been digested. I wasted around €800 to worsen my health, and now I'm forced to throw it all away. never again
