Vitamin C (Ascorbic Acid) - 80 MG
Vitamin c is required for your body to produce collagen and neurotransmitters, and it is included in a nighttime fat burning supplement like this as it can help to promote muscle repair and recovery while you sleep.
It will also keep your joints flexible, mobile, and healthy, and your muscles, bones, immune system, and teeth strong. It can even boost metabolism and prevent diseases to make sure that you never have to miss a workout and can keep your weight loss journey on track.
The problem is, vitamin c in supplement form is only useful if you consume at least 2,000 mg per day. As the PhenQ PM night time fat burner contains just 80 mg of ascorbic acid, it just isn't strong enough to be of use (1).
Vitamin B1 (From Thiamine HCL) - 4 MG
Vitamin B1 is essential for the metabolism of nutrients in your diet and for promoting muscle growth and development.
The issue here is that the daily dosage of vitamin b1 to aid with metabolism and sleep is said to be 1.2 mg. meaning we've got way more than is necessay(2).
Vitamin B6 (From Pyridoxine HCL) - 5 MG
Vitamin B6 plays a role in countless functions in the human body. It can boost metabolism and immune functions, keep you healthy so you don't miss workouts, and even support weight loss directly.
However the dosage is again an issue. With the 5 mg present in the PhenQ PM nighttime fat burner being almost three times the RDI it is rather uncessary, generally the dose to improve sleep doesn't need to be nearly this high and the same applies for weight loss (3).
Biotin (As D-Biotin) - 120 MCG
Biotin, also known as vitamin b7, controls carb, protein, and fat metabolism, keeps the bones, skin, hair, and nails strong and healthy, and even has some evidence to suggest it helps combat joint issues (4).
Vitamin B5 (As D-Calcium Pantothenate) - 10 MG
Vitamin B5 has the ability to boost your basal metabolic rate, brain functions, memory, energy levels, nervous system, and production of neurotransmitters, which will enhance your exercise performance and help you lose weight naturally (5).
Choline (From DL-Choline Bitartrate) - 40 MG
Choline can produce mental health benefits and reduce inflammation, which will improve your recovery time, focus, and exercise performance (6). However, it is primarily put in weight loss supplements as there are claims that it can enhance muscle contractions.
However, there is little to no conclusive evidence that it can actually do this. This means the only benefit that it may have in the PhenQ PM nighttime fat burner is to mildly boost your recovery, if it can even do that, given the miniscule dose that is present.
Chromium (From Chromium Picolinate) - 120 MCG
Chromium can improve the body's insulin response, blood glucose and energy levels, nutrient metabolism, and production of serotonin. This will improve your sleep quality, brain function, and muscular recovery, reduce your appetite, stop unwanted weight gain, and aid weight loss.
Unfortunately, these benefits will only be seen if you consume 1,000 mcg per day. As the PhenQ PM nighttime fat burner only contains 120 mcg, it simply is not powerful enough to be of any use (7).
Molybdenum (From Sodium Molybdate) - 100 MCG
The mineral molybdenum keeps the enzymes in the human body functioning correctly, aids DNA and protein synthesis, and combats toxins to prevent them from doing any damage.
However, as there has never been a reported case of molybdenum deficiency and the 100 mcg present in the PhenQ PM nighttime fat burner is relatively pointless (8).
L-Arginine - 1,200 MG
L-arginine is an amino acid that your body requires to produce nitric oxide, while it is also said to be beneficial for improving blood flow, blood pressure levels, and testosterone production, which would aid exercise performance, and for treating diabetes and erectile dysfunction (9).
The issue is, the only benefit of taking l-arginine supplements that has ever been proven is to boost your your nitric oxide production. However, the 1,200 mg in the PhenQ PM night time fat burner is well below the 3,000 mg required to be effective, so it is unlikely to even do that.
L-Lysine HCL - 1,200 MG
While l-lysine is an essential amino acid, there is very little reason to take it in supplement form, other than for people who are dealing with certain health conditions (10).
While there are claims it can reduce anxiety and fat accumulation by blocking stress hormone production, aid calcium absorption, improve wound healing, and promote effective insulin activity and blood sugar control, none have been proven, so its inclusion in PhenQ PM is likely of no use.
L-Theanine - 200 MG
L-theanine is an amino acid that plays a key role in maintaining a healthy sleep wake cycle, reducing stress and anxiety levels, boosting relaxation, sleep quality, focus, and immune and brain functions, making it easier to fall into a deep sleep, and enhancing your overall health.
It is a huge asset in dietary supplements for losing weight, as its effects can boost the natural fat burning process and your overall weight loss, while enhancing your exercise performance and recovery time.
This is actually also the only instance where an optimal dose of a useful ingredient is present in the PhenQ weight loss pills (11).
5-HTP (5 Hydroxytryptophan From Griffonia Simplicifolia Seed Extract) - 150 MG
The amino acid 5-HTP is quite unique in that it can easily pass across the blood brain barrier.
This allows it to effectively improve the brain's production of serotonin, boosting your sleep quality, reducing stress and anxiety levels, preventing depression, promoting relaxation, supressing your appetite, and accelerating both body fat burning and overall weight loss (12).
Unfortunately, studies suggest that the optimal daily dosage of 5-HTP is between 200 and 500 mg when it comes to sleep although 150mg isn't bad.
