It is clarified that supporting growth is not just about taking vitamins and minerals. Growth supplements should be taken in combination with a nutritious diet, proper sleep and frequent exercise to have the best results. Children should also get protein, calcium and vitamins from a variety of sources in daily meals to ensure adequate nutrition and absorption, including legumes, leafy greens, whole grains, mushrooms, fish, dairy products, etc. Please note that the contents of micronutrients in our products have been thoroughly formulated for different groups of users to optimize absorption and efficacy. Taking higher contents of micronutrients from supplements than recommended, especially vitamins, can be counterproductive for the users. If your children already have a balanced and nutritious diet, actually they will not have to take other multivitamin supplements alongside our product. In case they do not get adequate vitamins and minerals from daily meals and have to take other dietary supplements, please consult your healthcare providers for proper instructions, or reduce doses of the multivitamins taken to balance the nutrient intake. To get the best results for their height increase, your children should also pay attention to other factors: - About exercise: they should frequently exercise or play sports that are good for height growth such as swimming, basketball, volleyball, badminton, cycling, yoga, etc. - About nutrition: they should have a healthy and nutritious diet (more protein, vitamin C, Zinc in daily meals) and avoid overusing sugary foods, greasy foods as well as some drinks like coffee, wine, beer, carbonated water and other stimulants. These unhealthy foods and drinks adversely affect the absorption of nutrients that work for height growth. - About sleep and living habits: they should sleep 8 hours per day, go to sleep before 11:00 PM, maintain good mental health, and avoid stress.
