Omega-3 (EPA + DHA) at 2g+ Daily<\/h3>\n<p>Decades of data from the REDUCE-IT trial and VITAL study show clear cardiovascular and inflammatory benefits at meaningful doses. Most “fish oil” products under-dose at 300-500mg. Green Shark’s formulas start at 2,000mg combined EPA\/DHA because that’s the threshold where measurable effects appear in blood markers and longevity biomarkers.<\/p>\n<h3>2. Magnesium (Glycinate or Threonate Forms)<\/h3>\n<p>Magnesium is involved in over 300 enzymatic reactions, including those tied to mitochondrial function and sleep quality \u2014 both foundational to healthy aging. Yet 50%+ of adults are deficient. Human trials consistently show improved insulin sensitivity and reduced inflammation when serum levels are optimized. Skip the oxide form; it’s barely absorbed.<\/p>\n<h3>3. Vitamin D3 + K2 (MK-7)<\/h3>\n<p>The combination is non-negotiable. Large cohort studies (including NHANES data) link optimal Vitamin D levels to lower all-cause mortality. Pairing it with K2 ensures calcium goes to bones instead of arteries. Most longevity “stacks” forget this synergy and under-dose D3 below 4,000 IU.<\/p>\n<h2>How Green Shark Co. Cuts Through the Noise<\/h2>\n<p>We don’t chase trends. Every batch is third-party tested for actual potency. We publish full Certificates of Analysis on our site. Our customers aren’t buying hope \u2014 they’re buying measurable inputs that support the biological systems proven to influence healthspan.<\/p>\n<p>If you’re serious about longevity, stop chasing the next viral compound.
