Beta-Carotene

A healthy result should fall into the range 0.1 - 2.71 mg/L.

Beta-Carotene is an oxidative stress marker.

– Beta-Carotene is involved in antioxidant protection.

– Beta-carotene is converted into vitamin A in the liver.

– Beta-carotene & other carotenoids are converted to vitamin A (retinol), involved in vision, antioxidant & immune function, gene expression & cell growth.

– The absorption of beta-carotene and its conversion to vitamin A varies among individuals.

– The most well studied carotenoid is beta-carotene.

– Carotenoids are the plant sources of vitamin A.

– A single beta-carotene is converted to 2 molecules of vitamin A.

– Of all the carotenoids, beta-carotene is converted into retinol most efficiently.

– Supplementation with beta-carotene is a safer alternative than vitamin A.

– The conversion of beta-carotene (provitamin A) to vitamin A (retinol) is accelerated by thyroxin and is increased in hyperthyroidism.

Beta-Carotene has antioxidant and other roles independent of vitamin A. Body pools of the two compounds are maintained independently so that, unless vitamin A levels are initially low, increased intake of beta-carotene may not affect higher levels of vitamin A.

Blood concentrations of carotenoids are the best biological markers of fruit and vegetable consumption. A large body of epidemiological evidence suggests that higher blood concentrations of β-carotene and other carotenoids obtained from foods are associated with lower risk of several chronic diseases.

Because vitamin A is a fat-soluble vitamin, GI conditions affecting the absorption of fats (cystic fibrosis, pancreatic insufficiency, IBD, or small-bowel surgery) may decrease the vitamin A absorption. Patients with low vitamin A levels may have an increased risk of respiratory infections or infertility issues. If you have low vitamin A levels, a check of fatty acid levels is advised.

Supplementation with alpha-tocopherol or beta-carotene does not prevent lung cancer in older men who smoke.

Beta-Carotene result calculator

insert the value from you Beta-Carotene test result.

What does it mean if your Beta-Carotene result is too low?

Increase consumption of beta-carotene containing whole foods.

Sources of beta-carotene:

– Carrot

– Pumpkin

– Sweet potato

– Spinach

– Kale

– Turnip greens

– Beet greens

What does it mean if your Beta-Carotene result is too high?

Decrease consumption of beta-carotene containing food sources/supplements.

Is your Vitamin A level low while your beta-carotene level is high?

People with low thyroid function may have a slowed conversion of beta-carotene to vitamin A, and thus have a profile with an elevated beta-carotene and low vitamin A. In such a situation it may be warranted to consider a thyroid function, which can also be influenced by tyrosine and iodine levels.
