Overview

The effectiveness of this product is severely hampered by the extensive use of proprietary blends, which obscure the actual dosages of its purported active ingredients. While some ingredients like L-Theanine and Melatonin are known for sleep support, their specific amounts within the blends are unknown. The 'fat-burning' components are not only likely underdosed for significant effect but are also questionable for a PM formula aiming to promote sleep. The use of poorly absorbed mineral forms further compromises efficacy.

The Good

Contains some known sleep-promoting ingredients: Melatonin and L-Theanine, even if potentially underdosed, are common and effective sleep aids.

Includes general health support: Vitamin D3, Vitamin B6, and Magnesium are beneficial for overall health, though Magnesium is in a poorly absorbed form.

Herbal relaxation blend: The "Sleeptrition Blend" includes traditional calming herbs like Valerian, Lemon Balm, Chamomile, Passionflower, and Hops, which can individually contribute to relaxation and sleep, despite likely being underdosed in a blend.

The Bad

Proprietary Blends Mask Dosing: The "Sleeptrition Blend" and "BioTherm" are proprietary, making it impossible to determine individual ingredient dosages for efficacy or safety.

Underdosed Key Ingredients: Essential sleep aids like Valerian Extract, Lemon Balm Extract, Chamomile Extract, Passionflower Extract, Hops Extract, and Melatonin are likely underdosed as components of a 1190mg blend, with many effective doses for these ingredients ranging from 300mg to over 1000mg individually.

Questionable "Fat Burner" Efficacy: The inclusion of Green Tea Extract, L-Carnitine, Cayenne Powder, and Chromium for fat burning in a nighttime formula, especially at undisclosed or likely low doses, has limited research backing for significant overnight fat loss and the doses are likely too low to be effective.

Is it for you?

Best For: Individuals looking for sleep support with an added metabolic boost, those avoiding daytime stimulants.

Skip If: You are pregnant, nursing, or have a medical condition; consult a doctor if taking other medications.
