Primal Grow Pro Ingredients List A To Z: Seven Names And The Dose Each Was Studied At

By Primal Grow Pro Team · Medically reviewed by Dr. Kambiz Tajkarimi, MD · Last updated October 15, 2026 · 10 min read

B is for Bacopa monnieri

A botanical with a real research record. A 12-week trial in older adults and a second 12-week trial in adults over 55 both used 300 mg a day and both improved recall measures against placebo. A 2026 network meta-analysis of 29 trials found only the 600 mg a day arm separated from placebo on working memory.

The commonest side effect in those trials was gastrointestinal: more stool frequency, cramping and nausea than placebo. That is the reason the seller’s own instruction is to take the capsule with a meal.

On the label: no amount.

G is for Ginkgo biloba

The best-known name on the list and the one with the steadiest number. 240 mg a day is the reference amount. The Ginkgo Evaluation of Memory trial gave 120 mg twice daily to 3,069 adults for a median of 6.1 years and found no reduction in dementia incidence. The confirmatory trial puts 240 mg in its title.

The circulation claim was tested where it should be easiest, in legs. The Cochrane review of ginkgo for claudication found no clinically meaningful benefit on walking distance. The bleeding reputation is weaker than its fame: a secondary analysis found no effect on coagulation or bleeding time.

On the label: no amount.

H is for Huperzine

The odd one out by scale. The U.S. phase II trial used 200 or 400 micrograms twice a day. That is a thousandth of the unit everything else here is measured in. It is an acetylcholinesterase inhibitor, and vivid dreams are reported with that class, which is why the site’s how-to-use page says to move the capsule to the morning if sleep changes.

A meta-analysis of twenty trials reported benefits in Alzheimer’s disease but judged most of the trials to be at high risk of bias. The Cochrane review in mild cognitive impairment and the one in Alzheimer’s disease both called for better trials.On the label: no amount. Huperzine is also absent from the seller’s “Inside Primal Grow Pro” graphic.

L is for L-carnitine and L-glutamine

L-carnitine

The one trial that fits this product’s use case gave 120 men aged 60 to 74 propionyl-L-carnitine 2 g plus acetyl-L-carnitine 2 g a day for six months, against testosterone and placebo. Four grams a day is more than any capsule holds. A placebo-controlled study in diabetic men reported lower markers of endothelial damage, again at gram quantities and alongside a prescription drug.

L-glutamine

Measured in grams per kilogram of fat-free mass in a dose-tolerance study, which is 20 to 60 g in a sitting for an average man. A review of its metabolism covers its clinical uses. No trial connects it to male vitality at any dose.

On the label: no amount for either.

S is for St. John’s wort

The ingredient that decides whether this bottle is suitable for anyone on a prescription. It activates PXR, induces CYP3A4 and P-glycoprotein, and lowers blood levels of hormonal contraceptives, ciclosporin, digoxin, tacrolimus, indinavir, warfarin, alprazolam and simvastatin among others, per a 2020 clinical review.

A randomised trial at 300 mg two or three times daily found intracyclic bleeding rising from 35% to between 77% and 88%. The depression trials used 600 to 900 mg a day of extract. How strongly the herb induces those enzymes depends on its hyperforin content, which this label does not state.On the label: no amount. St. John’s wort is absent from the seller’s “How Primal Grow Pro Works” graphic.

V is for Vinpocetine

Not a plant extract. A semi-synthetic derivative of vincamine, made in a laboratory, and a prescription medicine in several countries. The Cochrane review found three trials at 30 to 60 mg a day and called the evidence inconclusive.

An FDA laboratory analysis of 23 U.S. supplements found 0.3 to 32 mg per daily serving, and six with none. A National Toxicology Program study found dose-dependent post-implantation loss, reduced fetal weight and ventricular septum defects in rats and rabbits. That is why the bottle should stay away from anyone who could become pregnant.On the label: no amount.

What does the whole list look like against one capsule?

The middle column describes single-ingredient trials. It describes nothing about this capsule.

A large capsule holds roughly 500 to 800 mg of powder. Ginkgo at its research amount is 240 mg, bacopa at its floor is 300 mg, and that is two of the seven before carnitine, which was studied in grams. One capsule cannot carry every name at the amount its trials used. The seller publishes no figures, so this website does not guess which names got the room.

Price and policy, for the record: $69 for one bottle, $118 for two, $196 for four, free U.S. shipping, 60 days money back from purchase with opened bottles included. Not FDA approved, as no supplement is.

Frequently asked questions

Our view

An ingredients list is only as useful as the numbers beside it, and this one has none. Our view is that the seven names are a reasonable pick from a real literature, two of them have good single-ingredient evidence, and the bottle cannot hold all seven at the amounts that evidence used.

If one name is why you are here, buy it alone with a figure on the label. If one capsule a day is why you are here, this is that capsule, and the 60-day window is long enough to find out how you get on with it.
