Why choose SIRE I?
Built from a father’s question
Sebastian wanted a practical way to take part when he and his wife were preparing for a baby. He co-founded SIRE with Matt, a holistic nutritionist, to make men’s part in preparation more straightforward.
Choose how you continue
Keep three bottles on hand with the 90-day supply, plus practical guides to organise your routine and meals.
The ingredients, explained
Understand what goes into your routine.
Preparing for fatherhood starts with understanding your nutrition. Explore the roles of the ingredients in SIRE I.
Energy for working cells
CoQ10 + L-carnitine
CoQ10 helps cells produce energy. Carnitine helps move fats into the parts of cells that use them for fuel. Sperm need energy to move, which is why researchers study these ingredients in men with reduced sperm motility.
The body’s antioxidant defences
NAC + selenium + vitamin E + alpha-lipoic acid
NAC provides a building block for glutathione, one of the body’s antioxidants. Selenium contributes to antioxidant enzymes, vitamin E helps protect cell membranes, and alpha-lipoic acid is involved in cellular energy metabolism and antioxidant activity. These functions are relevant to research on oxidative stress and sperm.
Making DNA and new cells
Zinc + copper + folate + vitamins B6, B12 & A
Zinc, folate and B12 help the body make DNA. Copper and B6 help enzymes carry out everyday cell functions. Vitamin A is involved in the signals that guide sperm development.
Ingredients still being explored
Ashwagandha + lycopene
Ashwagandha root extract and lycopene have been investigated in human studies of semen quality. Results depend on the ingredient form, the men studied and the measures used. Explore the research to understand what each study can tell us.
What does this mean for you?
The formula brings together nutrients with established biological roles and ingredients studied in men’s reproductive health. Ingredient studies use different doses, forms and populations; they do not establish results for SIRE. Explore the evidence and discuss your individual needs with a qualified professional.
SIRE brings these ingredients together in one daily supplement. It complements food and healthy habits; it does not replace fertility assessment or individual advice.

Sebastian & Matt · Co-foundersWhy we started SIRE
Preparation should be something we share.
When Sebastian and his wife were preparing for a baby, he saw how much thought and effort she was putting into it. He wanted a practical way to do his part, too.
That question became SIRE. Co-founded by Sebastian, a father, and Matt, a holistic nutritionist, it makes men’s preconception preparation a little more straightforward.

Is SIRE I right for you?
For men taking part in preconception preparation.
Consider SIRE I if you want selected ingredients combined in a daily capsule supplement, with a choice of one-time or recurring supply.
Already taking a multivitamin or other supplements? Ask a qualified healthcare professional to review the combination. SIRE I is not a complete multivitamin, a fertility treatment or a substitute for individual care.
A balanced diet, movement and rest remain part of preparation. If you are receiving fertility care or take medication, discuss suitability with your clinician.
A little clarity
Good questions. Straight answers.
A thoughtful decision starts with clear information. Here’s what to know before you begin.
Ask us a questionIs this a subscription?
Only if you choose it. The 30-day and 90-day one-time options are delivered once and have no recurring charges. The optional three-bottle subscription is delivered and billed every three months. Current prices appear in the purchase selector. Review the subscription policy before ordering.
Why choose 90 days?
The 90-day option puts three 30-day bottles in one order, so your next two bottles are already on hand. The current price and any saving compared with three single bottles appear in the offer selector. The one-time option does not renew automatically. Ninety days describes the supply and planning window, not a promise of results.
Are the resources available before purchase?
Only cover previews are public. Either 90-day option pairs with the 8-page Preparation Companion and 12-page Food & Planning guide. The 30-day supply pairs with the 4-page Quick-start Essentials. Your included guides are emailed after successful payment. Subscribers receive the Routine Rescue Kit link in their subscription confirmation email. Product and safety information will never require a purchase.
What extra do subscribers receive?
Both 90-day options include the 20-page preparation library. Subscribers also receive the separate 6-page Routine Rescue Kit. Six printable pages for travel, busy weeks, shared tasks and reviewing your next refill. A practical backup plan when life changes.
The subscriber-only Routine Rescue Kit link is included in your subscription confirmation email. Unlimited downloads.

How do I take SIRE I?
The supplied product information specifies three capsules daily with a meal and water. Always follow the directions and cautions on your product label and advice from your healthcare professional.
What if we’re already trying?
Discuss nutrition and fertility concerns with a qualified healthcare professional. SIRE I is a dietary supplement, not a treatment or a reason to delay appropriate assessment.
Is SIRE I a complete multivitamin?
No. SIRE I combines selected ingredients in a three-capsule daily serving. It is intended for men considering preconception nutrition, but does not supply every daily micronutrient. If you already take supplements, ask a qualified healthcare professional to review the combination.
What does the guarantee cover?
Your first three-bottle SIRE I order is covered for 90 days from delivery, including opened bottles, launch-priced orders and your first three-bottle subscription order. Subscription renewals are excluded. No return shipment is required. Limited to one claim per customer.
If you’re not satisfied, email sebastian@getsire.com with your order number within 90 days of delivery. We’ll refund the product price paid plus applicable tax to your original payment method. No return shipment is required.
One claim per customer. Subscription renewals are excluded. All other purchases, including single bottles, follow the standard 30-day return policy and its exclusions. Read the full guarantee and return terms.
Is the packaging plastic-free?
The bottle is amber glass and the lid is metal. The seal contains plastic.
Where do you ship?
Free standard shipping to the lower 48 states and DC on orders over $100 USD. Both current 90-day offers qualify. Orders of $100 USD or less ship for $5.95 USD to these destinations. Other US destinations have separate rates at checkout. Shipping policy.
