Physiological Properties and Effects:

Calcium D-Aspartic Acid

D-Aspartic Acid, the d isomer form of the amino acid aspartate, is an amino acid that is found naturally in several endocrine glands, including the testes and pituitary. While the correlation between DAA and testosterone production has been clinically documented, research indicates several possible mechanisms for these effects.

It’s likely that DAA acts as a neuromodulator influencing several pathways that govern the reproductive system, particularly testosterone production. Some studies indicate that DAA’s concentrated presence in the hypothalamus, pituitary, and testes identify this protein as an up-regulator of gonadotropin-releasing hormone (GnRH), luteinizing hormone (LH), growth hormone (GH), and testosterone. Some studies have found that DAA also stimulates a protein called StAR. StAR is necessary for the cholesterol transport in the cell that is needed for testosterone production. Further, its role in modulating the sexual drive implicates DAA assists nootropic activity, supporting health levels of dopamine and serotonin. Balanced levels of dopamine and serotonin have a range of significant benefits.

The existing research in human males suggests these mechanisms of action have plausible, real world activity. A six-month trial in average men, for example, saw increases to circulating testosterone of 30-60%. The increase over baseline persisted for the entirety of the trial in certain subjects, suggesting that DAA does not lose its effects over time or with repeated administration.

KSM-66® Full-spectrum Ashwagandha root extract (5% Withanolides)

Withania somnifera Dunal, colloquially known as Winter Cherry or Indian Ginseng, is an herb that features prominently in the traditional Indian medicinal system of Ayurveda. Known as Ashwagandha in Ayurveda, Withania somnifera is a critical ingredient in various Ayurvedic tonics and tinctures prepared as a traditional remedy for the treatment of various ailments.

Recently identified as a potent adaptogenic and target for therapeutic applications, Ashwaghanda has been the subject of numerous animal, pre-clinical, and clinical trials designed to examine its potential effects as an antioxidant, anti-carcinogenic, anxiolytic, antibacterial, antifungal, and immonumodulating compound. Ashwaghanda’s broad therapeutic potential is hypothesized to be the result of its robust phytochemical profile, including a wide swath of alkaloids, sitoindosides, and the highly biologically active withanolide group. As the principally biologically active compounds within Ashwaghanda, withanolides such as withanone, withaferine A, withanolides A, D, and G have been identified, isolated, and extensively studied in the various applications noted above.

Bulbine natalensis (stem) Extract (10:1)

Bulbine natalensis is a herb endemic to Southern African that has historically been used as an aphrodisiac in traditional medicine preparations. Recent animal research has demonstrated that the herb has healthy testosterone supporting effects in rats and may also elicit positive effects on cognition.

While Bulbine natalensis’ method of action is not certain, research conducted on rats suggests its testosterone-support functions stem from an increase in LH (luteinizing hormone). Luteinizing hormone is a hormone released by the pituitary gland to signal the Leydig cells in the testes to produce testosterone. The animal trial demonstrating an increase in LH also demonstrated an increase in rat testosterone levels at 14 days. The study revealed an increase in circulating testosterone of 40%.

In these same trials, an aqueous extract of the herb was found to dose-dependently lower estrogen levels in male rats. Research has not established whether the estrogen-lowering effects of Bulbine natalensis are a cause or consequence of its ability to support healthy testosterone levels.
