Details on Testosterone UP RED™
Boosts Testosterone and Increases Production
Testosterone UP RED™ features LJ100®, a patented extract of the herb Eurycoma longifolia, which helps maintain testosterone levels already within a normal range in men. Research shows LJ100® to enhance total testosterone for bodily needs.
This formula also provides Tribulus and Fenugreek, traditional botanicals that may support healthy testosterone levels. Tribulus may stimulate luteinizing hormone (LH) to signal production of testosterone.
Inhibits Conversion to DHT (Dihydrotestosterone)
Always a working organism, the male body is not hormonally static. Testosterone is often converted into other hormones like dihydrotestosterone (aka DHT - which may contribute to hair loss).
One ingredient in this formula helps to preserve testosterone in pure form, for greater circulation in the body. Beta-sitosterols act like 5-alpha-reductase inhibitors. 5-alpha-reductase is an enzyme that converts testosterone to DHT, and inhibition will halt this conversion.[6,7]
Boosts Nitric Oxide
Nitric Oxide is a naturally-occurring compound in the body that plays a key role in cardiovascular health. Nitric Oxide is produced in the inner lining of blood vessels and helps to relax and dilate vessels, allowing more blood to flow throughout the body.
This unique formula features L-Citrulline, an amino acid that is readily converted to L-Arginine, which can then be converted into Nitric Oxide within the body.[8,9]
Testosterone UP RED™ also features Asian Ginseng traditionally used in energy-boosting formulas and Ginkgo as well as Cayenne, traditionally used to help support blood circulation. In addition, Ginkgo and Ginseng have been shown to support Nitric Oxide synthesis in animal studies and in vitro.[10,11]
Testosterone UP RED™ also includes beetroot, which naturally contains nitrates that can be used to produce nitric oxide in the body.
Medium Chain Triglycerides
As the word "Medium" denotes, MCTs are shorter than Long Chain Triglycerides (such as fish oil and flax oil). This reduction in molecular weight means they're absorbed much faster and immediately converted into cellular energy. The result is a quick burst of energy for the body.
In one study, polyunsaturated fatty acids in the diet were correlated with higher testosterone levels. Added Medium Chain Triglycerides ("good fats") may provide overall support via their beneficial fatty acid content.
BioPerine®, a concentrated extract of black pepper, is an important ingredient in all Irwin Naturals® products. Clinically studied in numerous trials, this botanical extract enhances the bioavailability of many of the ingredients in our formulations. When combined with Ginger to create a traditional Ayurvedic blend, the Irwin Naturals® BioPerine® Complex takes bioavailability to the next level.
Testosterone UP RED™ is a unique 2-in-1 formula for men of all ages. It is designed to help enhance male vitality and performance by boosting testosterone levels already within the normal range and supporting nitric oxide to enhance male physical response during any physical activity. The key ingredients at the center of this amazing product are LJ100® Longjack and L-Citrulline. This product can be taken daily for ongoing maintenance of men's health and well-being.
