Nature Made is a trusted brand for vitamin supplements. Over the years, I have taken different supplements made by Nature Made and I feel like they work well and have helped with the variety of health concerns I have had. Our body needs vitamin D to be at its best. Our bodies need vitamin D to absorb calcium. Our biggest source of vitamin D is from exposure to sunlight. I live in a northern climate and do not get much sunlight in the winter months. I am at an age where calcium is important to maintain good bone health so I decided to try this the D3 5000 IU Liquid Softgel from Nature Made. It is easy to swallow with a drink and makes me feel better. I have more energy and less aches and pains. I have also read that Vitamin D can help ease symptoms of people who suffer from fibromyalgia, fatigue, colds, flus, and other ailments. I recommend this for all who do not get regular sunshine or who do not eat food with vitamin D supplements.
