Want to start smaller?

Planning to try in the next few months?

The preparation window may already be underway.

Sperm development takes roughly 74 days. The months before conception are part of the preparation period—not just the day a couple starts trying. SIRE I is designed as a 90-day routine for that reason.

A shared beginning

Pregnancy preparation has traditionally focused on her.

Her preparation

  • Prenatal nutrition
  • Lifestyle
  • Appointments
  • Planning

His preparation

  • Nutrition
  • Lifestyle
  • Consistency
  • A deliberate preconception routine

His side deserves a plan too.

For many couples, her preparation already has a routine. His doesn't.

SIRE I gives his side one straightforward daily step.

A specific purpose

Why not just take a regular men’s multivitamin?

General-purpose nutrition has a different starting point. SIRE I is built around preconception preparation.

Why a 90-day routine?

FAQ

Before you begin.

Have another question? Contact →

Why start before trying to conceive?

Sperm development takes roughly 74 days. Starting before trying makes room for a consistent nutritional routine during the preparation period.

Why 90 days?

A 90-day supply spans the approximate 74-day development cycle. It is a practical preparation routine, not a deadline for a biological result.

How do I take SIRE I?

Take 3 capsules daily with food and water, or as directed by a qualified healthcare professional. Each bottle contains 30 servings.

Can I start with one month?

Yes. The 1-month option is a 30-day supply, purchased once. Use “Try 1 Month” beneath any protocol offer.

Is the primary 90-day option a subscription?

No. “Start the 90-Day Protocol” adds the 3-month supply as a one-time purchase. There is no recurring billing.

What if I’m not satisfied?

Contact SIRE with questions. The current return policy covers unused items in their original packaging within 30 days of receipt, with proof of purchase. Read the policy for full eligibility and instructions.

Where is SIRE manufactured?

The SIRE I label states that it is made in the USA in a GMP-certified facility.

Manufacturing claims are shown on the product label. FDA facility registration does not mean FDA approval of this supplement.

What does third-party tested mean?

It means testing is performed by an outside party. SIRE’s current product information states that the formula is third-party tested for purity and potency.

Does SIRE treat infertility?

No. SIRE is a dietary supplement intended to provide nutritional support. It is not intended to diagnose, treat, cure, or prevent disease.

Can I subscribe?

Yes. Open “Prefer automatic delivery?” in the first offer to see the current recurring price and terms. Subscription is optional and must be chosen explicitly.
