I have been using the supplements now for just over 2 months. At first I was hesitant because I've tried similar in the past but I have to say, I'm blown away by the results. My once brittle nails are noticeably stronger, my skin has a subtle glow and pores on my nose have tightened. I am excited to continue my journey with Ozena and have recommended to friends, both male and female.
I've been using Ozena now for nearly a month and I can already see a difference. My skin feels fresher and brighter, and the wife comments that I'm looking youthful (but that could be her just being nice!). Either way feeling more energised, invigorated and rested. Would definitely recommend.

Green tea leaves are prized in traditional Chinese medicine for their rich profile of polyphenols, specifically catechins, including epigallocatechin gallate (EGCG). Recent decades of clinical research have shown that EGCG from green tea leaves has a vast range of therapeutic properties, notably antioxidant, anti-aging, anti-inflammatory, anti-diabetic, and cardiometabolic benefits [1].
BioPerine® is a patented black pepper (Piper nigrum) fruit extract standardized for its piperine content. Piperine is a natural alkaloid known for its “bioenhancer” properties, improving the bioavailability of molecules that are typically poorly absorbed or extensively metabolized in the liver [13, 14].
Capsimax® is a clinically studied red pepper extract enriched in capsaicin, one of the principal compounds that imparts the spicy/hot intensity of peppers.
In turn, caffeine can help increase calorie expenditure and facilitate lipolysis (fat breakdown) [7].Forskolin is a compound found in the roots of Coleus forskohlii, a tropical plant that has been used in traditional medicine for centuries. Research has demonstrated that forskolin acts to increase a key messenger in cells called cyclic adenosine monophosphate (cAMP) [3]. In turn, the breakdown of fatty acids (lipolysis) and metabolic rate are upregulated. Forskolin also appears to enhance insulin sensitivity, thereby promoting enhanced utilization of carbohydrates and boosting energy levels. [4]
Caffeine is a well-documented ergogenic aid that enhances physical and cognitive performance. Research indicates that caffeine improves performance by reducing perceived exertion and delaying fatigue through adenosine receptor antagonism, increasing central nervous system excitability [5, 6]. In turn, caffeine can help increase calorie expenditure and facilitate lipolysis (fat breakdown) [7].
L-Theanine is an amino acid found in green tea known for its ability to promote nervous system relaxation without sedation. Research suggests that L-Theanine modulates nervous system function, resulting in improved attention, reaction time, and reduced stress. [8, 9] Additionally, L-theanine has been shown to work in synergy with caffeine to support cognitive function and overall performance [10]. L-theanine may help smooth out the overstimulation sometimes caused by stimulants, preventing energy crashes and promoting sustained mental clarity.
