Yeast hydrolysate is at a full dose here and has the most direct support for men. In obese men and women taking 1 gram daily for 10 weeks, body weight, body fat and belly fat fell more than with placebo, without loss of lean tissue [1]. In 30 obese women, half a gram daily for 8 weeks lowered weight and body fat and reduced calorie intake, though men were not studied [2]. Both trials were small and short. Chromium is also at a full dose, but its effect is small. Reviews of trials found about 0.5 to 1.1 kilograms of extra weight loss, of uncertain real-world value and partly low-quality evidence [3][4][5]. In people with type 2 diabetes it did not change weight or body size [6][7], and a high dose for 24 weeks gave no extra weight loss [8]. Ashwagandha here comes to 250 milligrams a day at two servings, less than the 600 milligrams used in most weight trials. A large review of 20 trials found no effect on weight or body fat [9], and another found no clear fat loss with resistance training [10]. Some single trials found weight or fat loss [11][12], while others found no change [13][14]. Animal and cell studies are never counted.

Biohacker Summary
Members Only0 of 10 recommend it
Chromium, the main ingredient, drew comments from seven of the ten panelists, and the group leans toward recommending it: four recommend it and three are neutral. Those who recommend it point to insulin resistance, blood sugar control and better body composition, with one saying chromium picolinate works at a couple hundred micrograms and another saying he uses it in his practice. The neutral voices call it a mild effect on blood glucose or a secondary ingredient in blood sugar products, and one only notes that a med depletes chromium. Nobody gave a firm dose beyond that, nobody said they stopped taking it, and no one raised a caution about it. Ashwagandha is a smaller ingredient in this product, and most of the panel likes it for stress, cortisol and sleep, though some advise taking breaks from it.

- Recommends ashwagandha as an adaptogen with a profound effect on cortisol, acknowledging that it can make some people feel numb but may still be helpful.
- Discusses Ashwagandha as an adaptogen with quite a bit of evidence for various benefits like cognitive ability, stress, stamina, cardiovascular benefits, and lipid panels. He notes that long-term use might lead to a level of tolerance or an apathetic sense, suggesting it should be used when sincerely needed.
