The Claim

Goats exhibit detectable beta-carotene in plasma exclusively on day 10 of dietary supplementation, whereas cattle maintain plasma beta-carotene concentrations that are proportional to dietary intake over a 120-day supplementation period.

Source: Low cleavage activity of 15,15'dioxygenase to convert beta-carotene to retinal in cattle compared with goats, is associated with the yellow pigmentation of adipose tissue.

Supports is higher

Support is ahead, but a single strong opposing study can change this.

Description
1 study reviewed
In plain English

When given the same dietary supplement, goats show beta-carotene in their blood only on day 10, while cattle maintain blood beta-carotene levels that match their intake throughout 120 days.

See the scientific wording

Goats show detectable beta-carotene in plasma only on day 10 of supplementation, while cattle maintain plasma levels proportional to dietary intake throughout the 120-day study.

Why this might work

Goats break down beta-carotene quickly in their intestines, so it disappears from the blood after a few days. Cattle break it down slowly, so beta-carotene stays in the blood for months and builds up in fat.

  1. Study: Low cleavage activity of 15,15'dioxygenase to convert beta-carotene to retinal in cattle compared with goats, is associated with the yellow pigmentation of adipose tissue.

    Goats quickly break down beta-carotene and clear it from their blood, while cows keep it in their bloodstream longer because they don’t break it down as fast.
