How Long Should I Take Supplements Before Trying to Conceive?
Start taking fertility supplements at least 3 months before trying to conceive — but here's why that timeline matters more than you think.
If you're Googling at 2am wondering when to start supplements, you're not alone. The conflicting advice out there ranges from "as soon as you stop birth control" to "a full year before." Here's what the research actually shows.
Why 90 Days Is the Magic Number
It takes exactly 3 months for an egg to fully mature before ovulation — this is called oogenesis. This timeline allows nutrients to build up in your body to a level that gives the most protection to your future baby against neural tube defects.
For him, supplements help support overall health and sperm quality, and sperm take about 74 days to develop fully. So that 90-day window covers a complete cycle for both of you.
What About Folic Acid Specifically?
You should begin taking extra folic acid at least 3 months before you become pregnant. The baby's neural tube develops during the first month of pregnancy — perhaps before you even know that you're pregnant.
That "maybe before you know" part is why timing matters so much. It's important to supplement with folate/folic acid before you start trying to conceive, as opposed to when you find out you are pregnant.
Can I Start Later?
If you have already stopped contraception, that's OK, start taking it now. It's never too late to start. But women taking prenatal vitamins at least 1 month before conception were noted to have higher number of confirmed pregnancies and shorter time to conception.
The Ideal Timeline
Begin taking fertility vitamins at least 3 months before trying to conceive, ideally 6-12 months. This gives your body time to build adequate nutrient stores for conception and early pregnancy.
Think of it like this: if your nutrient levels are like a reservoir and the tank is nearly empty, it will take some time to fill it to the point where your body has adequate levels.
What If We're Already Taking Random Supplements?
Your nightstand shouldn't look like a pharmacy. Not all supplements are created equally. The key is getting the right ingredients at clinical doses in bioavailable forms — not just taking everything you read about on Reddit.
This is your move — backed by science. All the essentials. Right ingredients. Right doses. Right protocol. See more about the 90 day protocol
