How will it help me?▾
Tribulus saponins are proposed to support luteinizing hormone release and healthy hormonal signalling — not a direct testosterone claim. The best-known human trial (12-week RCT, 180 men) showed improved sexual desire and function scores.
When will I feel a difference?▾
The supporting clinical trial ran 12 weeks; most people should expect to give it a similar consistent runway before assessing results.
How do I take it?▾
Take two (2) capsules once daily, 20–30 minutes before a meal with an 8oz glass of water, or as directed by your healthcare professional.
What is in it?▾
Tribulus Terrestris Extract (fruit), standardized to 45% Saponins — 1300mg per serving. No proprietary blend, no fillers, no binders.

The story

Born from
necessity.

At 25, an autoimmune diagnosis stopped everything. Not just physically — it exposed a fundamental flaw in how we think about health. The conventional model was skilled at isolating problems. What it couldn't do was see the whole system.

People doing everything right — eating clean, staying active — still hitting the same wall. The issue wasn't discipline. It was a body stuck without real support.

Vital Matter was built from that experience — formulas that address the system, not just the symptom.

Testosterone Claims? ✓ No direct testosterone claim — hormonal signalling only Many make unsupported testosterone claims
