WHY TADALAFIL

Blood vessels tighten as you age. Tadalafil helps keep them open.

HOW TADALAFIL WORKS

Opens blood vessels.

Supports circulation.

Tadalafil works on one enzyme in your vascular system. This single action supports vascular health, sexual function, and longevity.

PDE5 inhibited

Tadalafil inhibits PDE5, the enzyme that breaks down cGMP, the chemical signal that keeps blood vessels relaxed.

Vascular function supported

This vasodilation effect has been shown to help support sexual function (the FDA-approved use). But the same effect works throughout your vascular system. Daily low-dose use may also support cardiovascular and endothelial health.

cGMP preserved

cGMP can then stay active longer. This helps blood vessels stay relaxed which can help keep circulation running smoothly.

COMMON QUESTIONS

Questions, answered

What is tadalafil?

Tadalafil (generic for Cialis®) is an FDA-approved PDE5 inhibitor prescribed for erectile dysfunction and benign prostatic hyperplasia. Some physicians also prescribe it off-label at low daily doses within longevity protocols.

How do you take tadalafil?

Tadalafil is a daily tablet, taken with or without food. It can be prescribed as-needed or daily. Your doctor determines the dosage based on your needs and medical history.

What are the side effects of tadalafil?

The most frequently reported side effects are headache, flushing, nasal congestion, and back pain. These are typically mild and tend to resolve as your body adjusts. Tell your doctor if side effects persist or feel disruptive.

Who shouldn't take tadalafil?

Tadalafil should not be taken with nitrate medications (used for chest pain or heart conditions), because the combination can cause dangerous drops in blood pressure. 

It is also not recommended for people with severe heart disease, recent heart attack or stroke, or severe liver or kidney problems. Your doctor will review your full medication list and health history before prescribing.
