Blood pressure that keeps climbing. Nights broken by the bathroom. Energy that’s gone by noon. A bedroom that’s gone quiet. It looks like four problems. It’s often one: a sticky protein net called fibrin that builds in your blood vessels as you age, thickening your blood and starving the tiniest vessels first. Nattokinase is the enzyme that breaks fibrin down. Alvena has 10,000 FU, plus aged garlic, magnesium glycinate and CoQ10. Four ingredients, four jobs, one capsule every morning. Third-party tested, made in the USA.
