These suggestions are below the "Tolerable Upper Intake Limit" (UL), and are within ranges that don't have issues according to sources used for adults.

Alpha-carotene, beta-carotene, canthaxanthin, cryptoxanthin, lycopene, lutein, zeaxanthin are common cartenoids, which in natural form aren't known to have toxicity issues like Vitamin A does. Cartenoids convert into Vitamin A, by different units, when the body needs it. Synthetic beta-carotene generally doesn't have natural beta-carotene's beneficial properties, and it might be unhealthy. Mixed carotenoids from a variety of certain fruit and vegetable sources are best. Vitamin A intake should be below 1,000μg, and cartenoid amounts can exceed 3,500IU.
