  • L-Phenylalanine

    (200 MG)
    L-Phenylalanine is an essential amino acid that contributes to feelings of satiety by supporting the release of an intestinal hormone called cholecystokinin (CCK). CCK has been associated with feelings of fullness, which can help control appetite and support weight management goals (1, 2).

  • L-Taurine

    L-Taurine is an important component in bile production, which supports the digestion of fats, absorption of fat-soluble vitamins, and maintenance of healthy cholesterol levels. Additionally, L-Taurine is associated with natural energy support and mood enhancement without the side effects of caffeine (3, 4).

  • Theobromine

    Theobromine is a naturally occurring alkaloid found primarily in cocoa beans and is responsible for the stimulating effects of chocolate. It acts as a mild central nervous system stimulant, similar to caffeine, but with a milder impact on the heart rate and mood. Theobromine has been shown to promote relaxation, improve mood, and enhance cognitive function, making it a popular ingredient in various nutraceutical formulations (5, 6).

  • Caffeine Anhydrous

    (70mg) Comparable to a half cup of coffee.**
    Caffeine Anhydrous, when used responsibly, can be an essential component in weight loss supplements. It is known for its ability to increase alertness, focus, and reduce fatigue. It may also contribute to appetite control, enhanced fat burning through increased thermogenesis, and improved exercise performance (7, 8).

  • 7-Keto (DHEA)

    7-Keto, a derivative of DHEA, has gained attention for its potential role in weight management and overall wellness. It is a metabolite of DHEA, which is naturally produced by the body. Research suggests that 7-Keto supplementation may support healthy weight management, promote thermogenesis, and maintain overall well-being (8)(9). Unlike DHEA, 7-Keto does not convert into steroid hormones such as testosterone and estrogen, making it a suitable option for individuals seeking the benefits of DHEA without potential hormonal side effects. (9, 10).

  • Glucomannan (Umbrella Arum Seed Powder)

    Glucomannan is a natural, water-soluble dietary fiber derived from the roots of the konjac plant. Research suggests that glucomannan may support healthy weight management by promoting satiety, or the feeling of fullness, after eating (1)(2). This may help individuals better manage their food intake and maintain a balanced diet.

  • Bitter Orange Extract

    Bitter Orange Extract is sourced from the peel of the bitter orange fruit. This extract has been studied for its potential to support healthy metabolism and provide a natural energy boost (3)(4). Its bioactive compounds may help enhance the body's ability to break down stored fat and promote thermogenesis, contributing to weight management efforts.

  • Black Pepper Fruit Extract

    Black Pepper Fruit Extract, derived from the black pepper plant, is believed to offer several potential benefits for weight management. It may help stimulate gastric secretions and increase metabolic rate (5)(6). As a result, the body may burn calories more efficiently, supporting weight management goals when combined with a healthy diet and exercise program.
