PhenQ PM

PhenQ PM is an innovative dietary supplement formulated to support the body’s nighttime metabolism and lipolysis processes. It is specifically designed to optimize your hormonal, metabolic, and sleep cycles – the key components for effective weight loss. This is especially true for users who struggle with hunger cravings, cortisol imbalance, slow overnight metabolism, and poor sleep.

PhenQ PM contains all-natural ingredients, including amino acids (L-arginine, L-thiamine), minerals (chromium, selenium), and vitamins (vitamin B6, folic acid).

Phenylalanine in the formula is known to stimulate the hormone cholecystokinin (CCK) and gut hormones such as GLP-1, known to reduce appetite and body weight. A clinical trial published in the Journal of the International Society of Sports Nutrition found that pre-exercise supplementation of phenylalanine may stimulate whole-body fat oxidation.

Benefits

  • Optimizes the 3 stages of nighttime fat burning – increase in human growth hormones, flushing out excess cortisol, and appetite control
  • Boosts metabolism and burns calories as you sleep
  • Curbs excessive cravings to reduce your caloric intake
  • Contains relaxing amino acids and minerals that support sleep
  • Increases energy levels to last the entire day

Availability:

Phenq PM is available on the official website and online retailer websites such as Amazon and eBay. It costs:

  • 1 bottle - $64.99
  • 2 bottles - $129.99 + (1 FREE bottle)
  • 3 bottles - $194.99 + (2 FREE bottles)

The Liposet Shred Phase System Bundle is a comprehensive appetite control,fat-burning, and metabolism stack designed for the cutting phase. It is a day-to-night fat-incinerating solution for individuals looking to get slimmer, shred pounds, or break a plateau. The Shred Phase System consists of three different supplements: Daytime Hunger Control, Overnight Fat Burn, and Burn & Preserve Muscle.

The Overnight Fat Burn is the nighttime fat burner in this collection. It works to intensify thermogenesis, elevate rest-based metabolism, and promote restorative sleep. The key ingredients in this fat burner are Ashwagandha, CLA, Green Coffee Bean, L-Theanine, Magnesium, and White Kidney Bean.

A 2020 study published in the Nutrients journal indicates that White Kidney Bean Extract (WKBE) aids weight loss, inducing small (average 2.6 kg) but potentially meaningful reductions in body weight in humans on a short-to-medium term basis compared with a placebo.

Benefits

  • Improves fat metabolism and burns fat for energy
  • Reduces carbohydrate absorption, thereby inhibiting fat storage
  • Lowers cortisol levels, reduces stress, and promotes restful sleep
  • Preserves lean muscle mass and supports muscle function
  • Elevates energy levels, keeping you energized for your daily tasks

Comparisons and Buying Considerations

  • Check for ingredients that support both sleep and metabolism - Research the ingredients on the label and ensure there are fat burners and sleep enhancers present. If these ingredients have scientific support, that’s even better.
  • Beware of proprietary blends and hidden stimulants - Products that do not list their ingredients with their amounts clearly are a big NO. Such products may have very low amounts of ingredients, rendering them ineffective. In the worst-case scenario, they may contain stimulants that could have harmful side effects such as insomnia, headaches, nausea, and increased heart rate and pressure.
  • Side effects & interactions – night-time fat burners could cause side effects such as anxiety, headaches, gastrointestinal issues, and sleep disruption. These weight loss supplements could also exacerbate the adverse effects when taken alongside medications, so for that reason, it is always recommended to consult your healthcare provider before using fat burners.
