I am taking Revive Active for approximately 8 months now, I find they give me energy and helps to boost me up, I had run out of them for approximately 1 week and I found my energy levels had really decreased and now I wouldn't go a day without them, when I went on holidays to Spain I even brought my weeks supply with me, I would never go without take my daily dose.. Great investment 👌 also Meaghers pharmacy does a great deal on purchasing in bulk... Best ever 🤩
