Black Magic Supply | Super Natty Shred Stack | 2-Product Stack

PrimaVie shilajit is a fulvic acid-rich mineral complex studied for effects on cellular energy metabolism, redox balance, and exercise resilience. Fulvic constituents may enhance mitochondrial electron transport indirectly by improving nutrient handling and reducing oxidative stress burden. Some human data also suggest support for vitality and male reproductive biomarkers in trained or active populations. Its inclusion here is most relevant to recovery quality, general performance readiness, and hormone-support positioning.

Vitamin D3 functions as a secosteroid hormone precursor with receptors expressed across muscle, immune, and reproductive tissues. Adequate status is associated with better neuromuscular function, recovery efficiency, and normal endocrine signaling, especially in athletes with insufficient baseline levels. Supplemental D3 is not acutely ergogenic, but it may improve the physiological environment that supports training adaptation over time. In stack design, it often serves as foundational support rather than a headline performance driver.

Boron is a trace mineral implicated in steroid hormone metabolism, inflammatory regulation, and mineral handling. Emerging human evidence suggests boron intake may influence free hormone fractions and vitamin D utilization, though effects depend heavily on baseline status and dose. The evidence base remains smaller than for core sports nutrition ingredients, so interpretation should stay cautious. In a hormone-support formula, boron is better viewed as a supporting micronutrient than a standalone driver.
