PhenAprin Tablet Ingredients
L-Phenylalanine
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).
Taurine
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. Taurine is also associated with natural energy support and a sense of well-being (3, 4).

L-Carnitine (as L-Carnitine Tartrate)
L-Carnitine is a naturally occurring amino acid found in various foods. It supports the body in converting fat stores into energy, which may contribute to a healthy weight management routine (5).

Theobromine
Theobromine is a naturally occurring compound found primarily in cocoa beans. It provides gentle thermogenic support and contributes a steady, even quality of energy, which is why it is a common ingredient in nutraceutical formulations (5, 6).

Caffeine Anhydrous
Caffeine anhydrous supports alertness and focus and provides thermogenic support that may contribute to appetite control and calorie burn as part of a balanced routine (7, 8). We disclose caffeine honestly so you always know your intake; see the Supplement Facts panel for the exact amount.

7-Keto (DHEA)
7-Keto is a naturally occurring metabolite of DHEA that has been studied for its role in supporting metabolic rate and thermogenesis (9, 10). Unlike DHEA, 7-Keto does not convert into steroid hormones such as testosterone or estrogen. Note for tested athletes: 7-Keto DHEA appears on the WADA prohibited list. If you are subject to drug testing, check with your governing body before use.

PhenAprinXR Capsule Ingredients
Glucomannan (from Umbrella arum Root Extract)
Glucomannan is a natural, water-soluble dietary fiber derived from the roots of the konjac plant. It absorbs water and expands gently in the stomach, which may contribute to a feeling of fullness before meals as part of a balanced routine (1)(2). At 800 mg, this is a supportive amount, below the 3 g per day used in the EU glucomannan weight-management claim. Important: take each capsule with at least 8 oz of water. Taking glucomannan without enough liquid may cause choking or throat or esophageal blockage. Do not take before bed or if you have difficulty swallowing.
- 1. Keithley J, Swanson B. Glucomannan and obesity: a critical review. Altern Ther Health Med. 2005;11(6):30-4. This review article evaluates the effects of glucomannan on weight management among overweight and obese individuals, suggesting that glucomannan may promote satiety and support weight loss efforts.Link

Bitter Orange Extract
Bitter orange fruit extract is a caffeine-free botanical sourced from the bitter orange fruit. It has been studied for its role in metabolism and thermogenic support (3)(4), complementing the glucomannan fiber without adding any caffeine to the formula.
