Hero Ingredients.

L-Carnitine L-Tartrate

 L- Carnitine is involved in cellular energy metabolism, helping transport fatty acids into mitochondria where energy is produced, an important pathway for cells with a high energy demand.

Evidence Note:

L- Carnitine has been extensively studied in nutritional and reproductive science research, including studies assessing sperm-related measures and shown to improve motility and concentration.

Acetyl-L-Carnitine
Hydrochloride

An active form of L-Carnitine included to support mitochondrial energy processes involved in normal cellular function. It’s commonly paired with L-carnitine because, together, they’re used in male fertility research to support sperm energy and movement, with combination protocols often reporting stronger changes than either form alone.

Evidence Note:

Evaluated in human semen-analysis research studies exploring sperm parameters and cellular energy metabolism and shown to improve motility and morphology, with larger improvements reported when combined with L-carnitine.

CoQ10

CoQ10 is involved in mitochondrial energy metabolism and acts as an antioxidant within cells, supporting cellular function where energy production and oxidative balance are important.

Evidence Note:

CoQ10 has been widely studied in human research examining semen analysis and oxidative stress markers and shown to improve motility and sperm concentration.

NAC (N-Acetyl Cysteine)

NAC is a precursor to cysteine and supports the body’s production of glutathione, one of the body’s key antioxidants involved in maintaining cellular redox balance.

Evidence Note:

NAC has been explored in clinical research examining oxidative stress and sperm-related biomarkers and shown to improve motility and morphology.

R-Alpha Lipoic Acid (R-ALA)

A biologically active antioxidant that supports mitochondrial enzyme function and participates in antioxidant recycling within the body.

Evidence Note:

Alpha-lipoic acid has been assessed in human placebo-controlled research looking at oxidative stress and semen parameters and shown to improve motility and sperm DNA integrity.

Zinc (bisglycinate)

Zinc contributes to normal fertility and reproduction, and helps with the maintenance of normal testosterone levels in the blood. Zinc bisglycinate is a highly bioavailable form used to support daily intake.

Evidence Note:

Frequently studied in male reproductive research - and shown to improve sperm concentration and motility.

Frequently Asked Questions

SuperSeed is a high-strength male prenatal supplement for men preparing for conception. It combines 19 evidence-led ingredients in one daily dose of four capsules, with every dose disclosed on the label. These include vitamins, minerals, dual-form carnitine, CoQ10 and NAC and more.


Men aged 20–45 who are planning to start a family, are actively trying, are considering or undergoing IVF, IUI or ICSI, or are preparing to freeze their sperm.
We recommend starting SuperSeed as early as possible. 

Sperm take around three months to develop and mature, so starting early means SuperSeed is part of your routine across at least one full cycle.

Sperm are among the most demanding cells the body makes. Each one takes around three months to develop. During that time, it needs energy to build its structure and power its movement, accurate copying and packaging of its DNA, and protection from oxidative stress, because sperm membranes are particularly vulnerable to damage.

SuperSeed is formulated to support the body during this pre-conception stage. It includes zinc, which contributes to normal fertility and reproduction and to the maintenance of normal testosterone levels in the blood, and selenium, which contributes to normal spermatogenesis. Zinc, selenium and vitamins C and E also contribute to the protection of cells from oxidative stress, while folate and vitamin B12 have a role in the process of cell division.

Alongside these, the formula also contains dual-form carnitine (L-carnitine and acetyl-L-carnitine), CoQ10, NAC, R-alpha lipoic acid, lycopene, astaxanthin, PQQ and more.

See Key Benefits above for the full formula.

If you’re planning to start a family then as early as possible. Sperm take around three months to develop and mature, so starting early means SuperSeed is part of your routine across at least one full cycle. 

We recommend starting now if you’re planning to start a family in the next 3–12 months, are actively trying, are considering or currently undergoing IVF, or are preparing to freeze your sperm.

I was recommended to take SuperSeed and was so impressed by the ingredient list and the quality of the product!

After a month, I am feeling great and very energetic.
I also feel so happy that I can contribute to the process, not leaving my wife to take all the responsibility with her supplementation.
Hoping for a great result!

Only just started taking Zygo, but I’m already noticing the difference! The pure nutrients seem to hit differently, with more energy, better stamina and a little extra something 😉🔥

I really like the convenience of having everything I need in one supplement rather than buying lots of separate ones. Just makes it easier to keep on top of, and it fits into my morning routine easily without much thought.

My nutritionist recommended SuperSeed for sperm health. They liked that it has more substantial doses of key ingredients compared with other supplements I’d previously looked at. I’ve been taking it for a few weeks now and feel really good on it so far. It’s still early days, but I’m happy I went with their recommendation.

Update*
We’ve just had a positive pregnancy test!! and I’m absolutely elated. From my experience, this product is the real deal. Couldn’t be happier.

My wife and I did IVF for our first baby. We wanted to try naturally again before going back for round 2 of IVF, so I started taking Superseed about three months ago after comparing it with a few other male fertility supplements.

What stood out to me was the number of ingredients in Superseed and, more importantly, the actual doses. A lot of the other products I looked at had similar ingredients listed but in much smaller amounts, whereas Superseed felt like a much more comprehensive and considered formula.

A lot of male fertility supplements seemed to have a huge list of ingredients, but at fairly low doses. What I liked about SuperSeed was that the formula has a clear focus on sperm health rather than just being another general multi-vitamin. It gave me a lot more confidence.

A clear place to start.
