Why this formula
Cellular energy. Antioxidant nutrition.
CoQ10 and L-carnitine have roles in cellular energy. NAC supplies a building block for glutathione, an antioxidant made by the body. SIRE brings them together with other selected ingredients for men’s preconception nutrition.
CoQ10 · ubiquinone
250 mgCoQ10 participates in cellular energy production and acts as an antioxidant. It has also been studied in men with reduced sperm motility.
N-acetyl cysteine
600 mgNAC supplies cysteine for glutathione. Researchers have studied NAC in relation to oxidative stress and semen quality in selected men with infertility.
L-carnitine tartrate
500 mgCarnitine helps transport fatty acids into mitochondria, where cells produce energy. SIRE includes the tartrate form.
Lycopene
24 mgLycopene is a carotenoid found in tomatoes and other red fruits, studied for its antioxidant properties.
Read the research behind the ingredients
The studies below concern individual ingredients in selected groups of men, not the finished SIRE formula. Study doses and forms are not necessarily the same as SIRE.
CoQ10 · placebo-controlled trial
Balercia et al. studied 200 mg of CoQ10 daily for six months in 60 men with reduced sperm motility. The trial examined semen measures; it did not test SIRE, which contains 250 mg per serving.
Read the studyNAC · before-and-after study
Jannatifar et al. followed 50 men with abnormal sperm motility and morphology taking 600 mg of NAC daily for three months. Without a placebo group, changes cannot be attributed to NAC alone.
Read the studyCarnitine · crossover trial
Lenzi et al. compared 2 g of L-carnitine daily with placebo in selected men with infertility. This is not equivalent to SIRE’s 500 mg of L-carnitine tartrate.

Why prepare ahead
Think in months. Start with today.
Sperm take roughly two to three months to develop and mature. That makes the months before conception a useful time to review nutrition, daily habits and your individual health.
About sperm development · ASRM- 01
Make a plan for your health.
Discuss your questions with a qualified healthcare professional. A supplement is one part of preparation alongside food, movement and rest.
- 02
Choose a daily moment.
If SIRE fits your plan, take three capsules daily following the directions and cautions on your label.
- 03
Choose how you reorder.
Subscribe for one bottle every month, or order three bottles together once. Ninety days is a supply length, not a promise of results.

Read guarantee eligibility and termsThe people behind SIRE
A father’s question. A nutritionist’s perspective.
When Sebastian and his wife were preparing for a baby, he wanted a tangible way for men to take part in the preparation, too.
He worked with Matt, a holistic nutritionist, on SIRE’s formula. Their aim: bring selected ingredients into one daily supplement, with a label you can understand and a routine you can follow.
Sebastian, father & co-founder · Matt, holistic nutritionist & co-founderQuestion & Answer
Why choose SIRE?
SIRE combines CoQ10, NAC and L-carnitine tartrate with selected vitamins, minerals and other ingredients in one three-capsule serving. The full label shows every amount. Co-founder Matt, a holistic nutritionist, collaborated on the formula; Sebastian brings his experience as a father. Choose a subscription or one-time supply based on how you want to reorder.
Why these ingredients?
The combination brings together ingredients involved in cellular energy and antioxidant processes, including CoQ10, NAC and L-carnitine. Some have been studied in selected men with infertility. Those studies inform the ingredient discussion; they do not establish the effects of SIRE’s finished formula.
How soon should I expect results?
SIRE does not have an established timeline for changes in sperm parameters or pregnancy outcomes. Sperm development takes roughly two to three months, but that is not a guarantee that a supplement will help. Do not delay fertility assessment or treatment while taking supplements.
How does the subscription work?
One 30-day bottle is delivered and billed every month until canceled. Pay $49.95 per delivery, plus applicable tax, with free standard shipping to the contiguous U.S. Shipping outside this area is calculated at checkout. Manage or cancel using the link in your subscription confirmation email.
Can I order without subscribing?
Yes. Choose one bottle for $64.95 once or three bottles for $164.95 once. Neither one-time option renews automatically.
Which option costs the least per bottle?
The subscription is $49.95 per bottle. The three-bottle one-time supply is $54.98 per bottle, rounded, and the single one-time bottle is $64.95. Three completed subscription deliveries total $149.85, compared with $164.95 for the bundle.
How do I take SIRE-1?
The bottle provides 90 capsules, a 30-day supply at three capsules daily. Follow the directions and cautions on your product label and advice from your healthcare professional.
What does the guarantee cover?
The current policy covers the first single-bottle subscription order for 30 days from delivery, even if opened, refunding the bottle price and applicable tax. Shipping and renewals are excluded. The first three-bottle order has a separate 90-day guarantee. Single one-time bottles follow the standard return conditions. Read the full policy for eligibility and exclusions.
Returns and guaranteesWhat does shipping cost?
Free standard shipping on subscriptions and three-packs to the contiguous U.S. (48 states + DC). One-time single bottles ship for $5.95 to those destinations. Outside this area, available rates are shown at checkout. Applicable tax is additional.
Is it suitable for vegetarians or vegans?
No. The current label lists a gelatin capsule. Review all ingredients and consult a qualified healthcare professional if you have allergies or dietary restrictions.
Can I take it alongside other supplements?
Ask a qualified healthcare professional to review the combination, particularly if you take medication or have a health condition. Follow the label’s cautions.
Is SIRE a fertility treatment or complete multivitamin?
No. SIRE is a dietary supplement containing selected ingredients. It does not provide every daily micronutrient and is not a fertility treatment. Discuss fertility concerns with a qualified healthcare professional.
