Beyond the Juice: What Actually Supports Blood Flow During Implantation

A study published in 2023 made its way around fertility circles for a good reason: it looked at something simple, a daily juice made from beetroot, watermelon and ginger, and found it was associated with better outcomes during ICSI (intracytoplasmic sperm injection) cycles.

It's a compelling finding. But the real value isn't the juice itself, it's what the juice was doing inside the body, and why that matters for anyone supporting their fertility naturally, not just through assisted reproduction.

What the study actually found

Researchers followed 436 women undergoing ICSI at a private IVF centre in Brazil. One group added a daily homemade juice of fresh beetroot, watermelon and ginger from the day of embryo transfer until their pregnancy test. The other group received standard IVF care alone.

The juice group saw a higher implantation rate (25.2% compared with 20.5%) and a higher clinical pregnancy rate (41% compared with 22%), both statistically significant (Halpern et al., 2023).

This is a genuinely encouraging result. It's also not the final word. The study came from a single IVF centre, and the same research group ran a smaller version of this trial back in 2019, so this finding hasn't yet been tested by an independent research team elsewhere. The published methodology also leaves some gaps, it doesn't specify how much juice participants drank or how much nitrate that amounted to, and it doesn't describe how (or whether) side effects were tracked. Worth holding onto as encouraging, not conclusive.

The mechanism matters more than the recipe

Here's the more useful takeaway: this study is really about nitric oxide, and nitric oxide isn't something you can only get from one juice blend.

Beetroot is naturally rich in dietary nitrates, which the body converts into nitric oxide. Nitric oxide helps blood vessels relax and widen, supporting circulation (Lundberg, Weitzberg & Gladwin, 2008).

Watermelon contributes L-citrulline, an amino acid the body converts into arginine, which also supports nitric oxide production and has been linked to improved vascular function in clinical research (Wong et al., 2021).

Ginger brings antioxidant and anti-inflammatory properties that may support healthy blood vessel function more broadly (Ayustaningwarno et al., 2024).

Put together, this isn't really "drink this juice to help implantation." It's "the body needs good blood flow to support implantation, and there are several dietary ways to support that."

Practical ways to apply this, without the juice

If a daily homemade juice isn't realistic (or you just don't enjoy it), the same nitric-oxide and antioxidant support can come from:

  • Leafy greens, beetroot, pomegranate and citrus fruits, all nitrate or antioxidant-rich foods that support the same physiological pathway

  • Gentle, consistent movement, which supports circulation independent of diet

  • A varied intake of colourful vegetables, berries and nuts, which support the body's management of oxidative stress around implantation

None of this is about chasing one hero food. It's about giving the body consistent nutritional support through several channels, rather than relying on a single ingredient to do the work.

Where this fits with a NaPro-aligned approach

For those following a NaPro-aligned approach to fertility, this research fits neatly into a broader principle: supporting the body's own natural processes, including blood flow, hormonal balance and inflammation, rather than looking for a single fix. The Halpern study is one data point in that picture, useful, but not the whole picture.

The bottom line

This finding is encouraging, not conclusive. Beetroot, watermelon and ginger bring nitric oxide-supporting compounds and antioxidants to the table regardless of what a single study proves, worth including as part of a varied, balanced diet for anyone trying to conceive.

If you're navigating your fertility journey and want support that looks at the whole picture, not just one study or one juice, book a discovery call to talk through a plan that's built around you.
