Stop a high-dose fertility / TTC formula when the test is positive. Switch to a prenatal that covers NHS folic acid through 12 weeks and vitamin D. Keep a decent omega-3 (EPA and DHA) if you already use one. A TTC tub is not automatically something to run into trimester two because it is not empty.
NHS pregnancy vitamins is still 400 µg folic acid daily through the first 12 weeks (5 mg if you have been prescribed it), plus vitamin D as advised (routine figure 10 µg; do not exceed 100 µg/day from supplements). Don’t take extra vitamin A / retinol or cod liver oil. Book the GP or midwife pathway.
Why a TTC formula and a pregnancy vitamin are different jobs
Preconception formulas are allowed to hold ingredients you would not automatically keep once there is a pregnancy: higher-dose CoQ10, NAC, ashwagandha, royal jelly, green tea extract, resveratrol, fertility-dose antioxidants. Pregnancy prenatals are built around folic acid (or a folate policy a midwife accepts), iodine, vitamin D, iron in a pregnancy-appropriate amount, and a conservative everything-else. Those lists overlap. They are not identical.
Continuing “because it was expensive” is how people end up taking ashwagandha and a green-tea extract into weeks they should be on a bland, boring prenatal. Save leftover capsules for a later TTC attempt if a clinician is happy, or don’t. Do not finish the tub “so it doesn’t go to waste” after two lines on a stick.
A practical stop / switch table
| When | TTC / fertility formula | What to do instead |
|---|---|---|
| Still TTC or in the 90 days before IVF | This is what those stacks are for | NHS folic acid 400 µg (or prescribed 5 mg) remains the baseline. Add omega-3. Follow the clinic. |
| Positive test (home or blood) | Stop the fertility formula | Start (or continue) a pregnancy vitamin with folic acid through 12 weeks plus vitamin D. Tell a GP/midwife what you were taking. For him: stop the sperm formula. |
| IVF pregnancy after transfer | Stop unless the unit gave a written exception | Early-pregnancy clinic rules win. |
| Chemical pregnancy / loss, then TTC again | Ask before restarting | Grief first. When medically cleared to try, the 90-day clock can start again. |
| Already pregnant and you found this page late | Stop the TTC extras now | Start folic acid / a pregnancy vitamin today if you have not. Mention what you already took at booking. |
How Vitality Revival formulas fit this switch
Stop Her Fertility and Him Fertility at a positive test. Her Fertility holds CoQ10 300 mg, NAC 400 mg and KSM-66 ashwagandha — extras you do not freelance into pregnancy. Him Fertility is a sperm-cycle stack, not antenatal care. If he still wants everyday energy after TTC, that is Him Revive, not a reason to keep the fertility tub going. We do not make a pregnancy vitamin; follow the NHS folic acid / vitamin D line and whatever your midwife names.
FAQ
Can he keep taking a male fertility stack in pregnancy?
It is not for the pregnancy. Stop unless you are already planning another cycle and a clinician says otherwise. Everyday energy is a different job from a sperm-cycle stack.
What about vitamin D and omega-3?
Vitamin D stays in the NHS conversation. Omega-3 from food or a pregnancy-appropriate oil is a separate, usually reasonable extra — check the vitamin A content.
