What makes PhenQ stand out is its research-backed ingredient blend, enabling it to attack fat loss from different angles:

  • α-Lacys Reset – The star of the PhenQ formula is α-Lacys Reset, a patented compound containing cysteine, alpha-lipoic acid, and magnesium. These three components work synergistically to turn up the body’s internal thermogenesis, accelerating metabolism and fat burning. In one study on α-Lacys Reset, volunteers lost 7.24% body fat, increased muscle mass, and experienced a 3.80% increase in lean body mass after just 6 months.
  • Capsimax Powder – Contains concentrated capsaicinoids extracted from hot chili peppers. Capsaicinoids increase thermogenesis and core body temperature. They also reduce appetite and prevent new fat formation by improving gut health.
  • Chromium Picolinate – A trace mineral that lowers sugar and carb cravings by optimizing insulin function. Chromium supports healthy blood glucose control.
  • Caffeine – A stimulant found in coffee beans that increases thermogenesis, lipolysis, and fat oxidation. Caffeine provides clean energy, heightens focus and alertness, and improves exercise performance.
  • Nopal – Nopal cactus is rich in amino acids and fiber which suppresses appetite by making you feel fuller. It’s high in antioxidants and flushes fluids from tissues for a leaner look.
  • L-Carnitine Fumarate – An amino acid that converts stored fat into energy. L-carnitine allows your body to utilize fat reserves as fuel, leaving less fat on your frame. It boosts energy levels and workout performance too.
  • InnoSlim – is a unique combination of ginseng and astragalus that has a proven ability to support weight loss. By stimulating the release of potent fat-burning hormones, it aids in enhancing your weight loss efforts. Additionally, it has been scientifically demonstrated to reduce the absorption of carbohydrates in the intestines, resulting in a decrease in calorie intake from carbohydrate-rich foods.

Instant Knockout contains a lower number of active compounds compared to PhenQ, but they are highly targeted and research-backed:

  • Caffeine Anhydrous – A fast-acting form of caffeine that suppresses appetite, provides energy for workouts, and synergizes with green tea for enhanced fat burning.
  • Glucomannan – A konjac plant fiber that swells in the stomach to induce feelings of fullness. Glucomannan reduces calorie intake by suppressing appetite.
  • Vitamin B6 and B12 – Essential for metabolizing carbs and fat. These B vitamins turn nutrients into energy instead of storing them as fat.
  • Cayenne Pepper Seeds – Contains the compound capsaicin which increases thermogenesis, metabolic rate, and calorie expenditure.
  • Piperine – The bioactive in black pepper that enhances bioavailability and absorption of all other ingredients.
  • Zinc – An important mineral for regulating appetite, digestive health, glucose tolerance, thyroid function, and more.

Comparing Dosages and Ingredients

The chart below compares the active compounds in PhenQ and Instant Knockout, along with their dosages:

Here is a breakdown of the key active ingredients in PhenQ versus Instant Knockout and their dosages per daily serving:

IngredientPhenQInstant Knockout
α-Lacys Reset25mg
Capsimax Powder15.5mg
Chromium Picolinate80mcg
L-Carnitine Fumarate150mg
Green Tea Extract500mg
Vitamin B65mg
Vitamin B1210mcg
Vitamin D37.5mcg

As you can see, while both contain metabolism-boosting compounds like caffeine and thermogenic agents, their formulas and dosages differ significantly.

PhenQ contains unique ingredients like α-Lacys Reset, Nopal fiber, and Chromium which Instant Knockout lacks.

Instant Knockout has higher levels of caffeine plus its own proprietary compounds such as glucomannan, Vitamin D3, and piperine not found in PhenQ.

These differences in ingredients and dosages impact the way each supplement aims to support weight loss. When choosing between the two, consider which blend of compounds best matches your needs and preferences.

While both contain metabolism-boosting compounds like caffeine and capsaicinoids, their formulas differ significantly. Instant Knockout has a much higher caffeine dose at 300mg vs 142mg in PhenQ which may be too stimulating for some.

PhenQ has the added benefit of ingredients like Nopal, L-Carnitine, and Chromium that target weight loss in other ways beyond just thermogenesis.

For athletes wanting to get shredded, Instant Knockout provides more direct metabolic enhancement. But PhenQ works better for those seeking overall weight loss through appetite reduction, energy boosting, and multi-pathway fat burning.

Comparing Real Customer Results

With both supplements, you can find plenty of before and after photos online showcasing fat loss results.

For PhenQ, both men and women seem to be losing 20lbs or more in the first 1-2 months. Appetite suppression leading to less calorie intake seems to be a common benefit.

As for Instant Knockout, most of the impressive transformations are in men doing heavy weightlifting and HIIT workouts. They show noticeable reductions in belly fat and love handles while maintaining muscle mass.

Women also praise Instant Knockout, but their results seem more moderate compared to the dramatic changes in male gym-goers.

Keep in mind that individual results can vary widely based on factors like diet, activity levels, genetics, and more. The safest bet is to temper expectations and give either supplement at least 2-3 months to work before judging its effectiveness. Consistency is key.
