Garlic compound increased muscle force in aged mice

Experiments in aged mice traced the benefits to a protein released by fat tissue that targeted the hypothalamus, a brain region.

In experiments in aged mice, a compound found in garlic and aged garlic extract increased muscle force and improved frailty measures. The compound, S-1-propenyl-L-cysteine, activated a signaling pathway in white fat tissue. This promoted the release of a protein that specifically targeted the hypothalamus, a brain region.

The researchers also reported that the compound increased blood levels of the same protein in people who maintained healthy amounts of body fat. The human finding concerned the protein circulating in the blood, rather than the muscle and frailty benefits reported in mice.

Why it matters

The work addresses whether signals from fat tissue to the brain can influence age-related muscle decline.

Caveats

The human finding was a change in a blood protein, not evidence of better muscle function. The abstract does not describe the human study’s design or report participant numbers, dose or duration.
