This product gives 1000 milligrams of concentrated garlic a day, which is above the 250 milligram dose that worked in studies. Garlic has strong human evidence for lowering blood pressure. A large pooled analysis of 108 randomized trials with 7137 adults found garlic lowered the top blood pressure number by about 3.7 points and the bottom number by about 2 points [1]. Another pooled analysis of 20 trials found drops of 5.1 and 2.5 points against placebo, with larger drops of 8.7 and 6.1 points in people with high blood pressure [2]. Seven placebo trials in people with high blood pressure found drops of 6.7 and 4.8 points, with no serious side effects [3]. The benefit appears mainly in people with high blood pressure, not in those with normal pressure [4]. For aged garlic extract, a different garlic form, clear effects showed up only above 1200 milligrams a day [5], and a one year trial using 2400 milligrams daily lowered the top number from about 148 to 140 [6]. Some smaller trials found no change. Animal and cell studies are never counted.

Biohacker Summary
Members Only0 of 10 recommend it
0 of 10 biohackers on our panel recommend it
Garlic is the main ingredient, and the panel leans favorable: four of the ten recommend it, four use it, one is neutral, and one warns, while one says he does not eat it. People take it for heart health, blood pressure and cholesterol, immune support, gut health, and detox, and one takes a 600 milligram capsule to offset a possible rise in a gut-made compound when using another supplement. Forms vary widely, from aged garlic extract and odor-free pills to raw cloves and cooked garlic, and several say to crush or chop it and let it sit for 10 minutes first. Garlic is often paired with avocado, olive oil, and eggs. Cautions are that one panelist feels less mentally sharp after eating a lot of it and warns of a bleeding risk for anyone on meds, and another avoids it because it worsens his digestive symptoms.
