When you are looking for a multivitamin, seek out those that contain 100% of the daily value of most of the ingredients. Since you are looking to increase your nutrition, you should try to get the most benefit possible. If they contain very little of each individual nutrient, there is no point in taking them at all.
Add the "sunshine vitamin" to your diet. Vitamin D is called the "sunshine vitamin" because it comes from sunlight. Since many avoid the sun because of cancer and health risks, they end up with vitamin D deficiencies. However, it's essential for absorbing and using calcium to maintain bone health. So, you should try getting at least 10 and 15 minutes of sun a day.
