Lamberts® A-Z Multi is a one-a-day formula providing all of the most important micronutrients, many at 100% RDA. But when it comes to Vitamin D Lamberts have included double the RDA, the level that is increasingly being recommended. This is a useful ‘maintenance’ level supplement that is suitable for those 13 years and upwards, and makes a good long term supplement for teenagers. It provides a useful amount of iron, a mineral that is particularly important for young women, especially if they are eating little red meat. This product provides an affordable way to ensure that the intake of key micronutrients will reach the recommended daily intake. You should also consider including Osteoguard®, a high strength calcium and magnesium formula and an Omega 3 supplement such as Lamberts High Strength Fish Oil 1100mg. Daily intake: 1 tablet
