Some sources suggest a lutein 10 mg dose. Others suggest 20 or even as much as 50mg per day. What’s the right choice? Are there any negative side effects to the higher doses? Is there something else to consider?
The first thing to consider is that a 6-10mg daily dose of zeaxanthin should also be taken. The benefits of the supplements are primarily for the prevention of an eye disease called Age-related macular degeneration or ARMD.
The macula is a small area of the retina, located inside the eye and responsible for central vision. Both lutein and zeaxanthin are found in the macula, but zeaxanthin is the dominant component of the central macula. Lutein dominates in the peripheral macula. So, obviously both of the carotenoids are important.
Can you take more than a lutein 10mg dosage without having unwanted side effects? In very large amounts, any of the carotenoids can cause bronzing of the skin. So, you’ll have a natural looking tan, without risking skin cancer. That doesn’t sound like a bad side effect to most people. So, why take a lutein 10 mg dose, when you could take 20 or 50?
Just from a strictly economical standpoint. It sounds like more would be better.
There are some nutrients that are toxic at higher dosages. Vitamin A, in the retinol form, is an example. The vitamin is often recommended for night blindness, because that is the first symptom of a deficiency. But, people should take beta-carotene.
Beta-carotene is found in carrots (ever seen a rabbit wearing glasses) and many other vegetables. The human body is able to convert the beta-carotene into vitamin A on an as-needed basis. Any excess is discarded. Of course, there is that whole problem with looking like you have tan, if you take too much. Beta-carotene is the primary carotenoid of significance to human health.
Some of the most learned natural health experts recommend a lutein 10mg dose for children between the ages of 5 and 12. For teenagers, 25mg is recommended. For adults, the recommended intake is 50 mg.
So, the right choice does depend on your age. Your weight is the actual determining factor. Age guidelines assume average weights for teens through adults and young children.
The minor carotenoids like zeaxanthin are present in foods, but only in very small amounts. Thus, they are referred to as micronutrients. The importance of micronutrients to human health is a subject of much study. The more we learn, the more we know, but sometimes we forget the things that we have known for many years.
There are some sources that suggest a lutein 10mg daily dose, but they neglect to mention the importance of vitamin A. Other nutrients that are important to visual health include vitamin B2 and B12, molybdenum and l-carnosine. Bilberry extract, because of all the different micronutrients that it contains is also recommended.
The better multi-nutritional supplements for children and adults contain at least the lutein 10 mg dosage. But, if you’re over the age of 12, you need more.[ad_2]
