Quick answer: Jelly Rock lists six ingredients: L-citrulline, L-carnitine, Panax ginseng, maca root, Rhodiola rosea and grape seed extract. No amounts are published. Most were studied at gram doses, more than a single gummy is likely to hold.
The label, decoded
First, an honesty note
Straight talk: the brand names six ingredients but does not publish how much of each is in a gummy. Most of these were studied at grams a day, while a gummy weighs only a few grams in total, sugar included. We do not invent doses; read the Supplement Facts on your bottle.
The six ingredients
L-Citrulline
An amino acid found in watermelon that the body converts into L-arginine and then nitric oxide, which helps blood vessels relax. Small studies in men used about 1.5 g a day for a month; gram amounts are hard to fit in one gummy.
L-citrulline research on PubMedL-Carnitine
Helps move fats into cells to be burned for energy. Trials in older men and in fatigue used 2 to 4 g a day. Most people make enough of it themselves.
NIH ODS carnitine fact sheetPanax ginseng
The classic "red ginseng" root. Some small trials found modest improvements in energy and sexual function scores at 1 to 3 g a day. It can affect blood sugar and interact with blood thinners.
NCCIH on Asian ginsengMaca root
A Peruvian root vegetable. Trials of 1.5 to 3 g a day reported small improvements in desire and mood after 6 to 12 weeks, without changing testosterone.
Maca research on PubMedRhodiola rosea
An "adaptogen" herb studied for stress-related fatigue. Some trials at 200 to 600 mg a day found less tiredness, but the quality of studies is mixed.
NCCIH on rhodiolaGrape seed extract
Rich in plant compounds called proanthocyanidins. Small studies suggest a slight effect on blood pressure and circulation. It may add to the effect of blood thinners.
