Food Period designs functional food products that support women’s menstrual cycles. Their first product is a set of energy bites, called Moon Bites, which are the first and only product commercializing the functional nutrition practice of seed syncing (or seed cycling).Seed syncing is commonly recommended by integrative health practitioners to help women regulate periods, manage symptoms of endocrine disorders like PCOS, or promote fertility.

The practice has women eat a set combination of seeds (flax, pumpkin, sesame, and sunflower) daily, depending on which phase of the menstrual cycle they’re in. Each seed contains a micronutrient or chemical compound that can help a woman’s body better modulate the production and elimination of estrogen and progesterone, whose fluctuations characterize the follicular (days 1-14) and luteal (15-28) phases of a woman’s cycle.

Despite being commonly used by integrative health practitioners, like naturopathic doctors and nutritionists, seed syncing is a natural practice that has largely been under-researched. Significant studies on how each of the four seeds affect hormonal levels and related symptoms do exist and can be reviewed here.

Seed syncing has helped tens-of-thousands of women achieve better hormonal balance and Food Period is proud that their Moon Bites have helped hundreds of women to experience more regular, less symptomatic periods thus far.



Britt Martin & Jenn Kim

In 2016, Britt was diagnosed with Hodgkin’s Lymphoma at age 25. During her six months of chemotherapy, she stopped getting her period. The only option her doctors offered was the birth control pill to reinstate her cycle, but unwilling to put more synthetic hormones into her body, she sought out natural alternatives. She learned about the functional nutrition practice of seed syncing – eating specific combinations of seeds during the different phases in her menstrual cycle to re-balance hormones naturally – and three months after following the practice, her period returned without any of the PCOS-related symptoms she’d previously experienced.

Jenn has lived most of her life in Vancouver and Los Angeles, although originally from South Korea. The West Coast dogma of natural health paired with the Korean focus on holistic remedies meant she never used birth control for her menstrual problems, despite being prescribed it by her doctor. When Britt – her best friend from boarding school – introduced her to seed syncing, within three months, her periods become more regular and her persistent hormonal acne completely disappeared.

The pair partnered to create a subscription-based service that helps women use natural food products to support their periods, starting with the commercialization of the seed syncing practice.

Food Period’s mission is to make natural solutions for hormonal health challenges more easily accessible to women.

What is seed cycling and can it really help with your period?

The concept of seed cycling (or seed syncing) has generated a lot of buzz lately, as it’s being touted as a way to manage symptoms of PMS and naturally regulate hormones.

Here’s how each stage of your period affects your mood

Let’s start with the basics: Your menstrual cycle abides by your hormones — specifically, estrogen, progesterone, and testosterone.

Ultimate Paleo Guide

I was in my Master’s degree program for nutrition when I first heard about the concept of seed cycling. The program I completed was based around using food as medicine, so I can’t say that I was necessarily surprised.

Real talk: Hormonal birth control options often leave us with more questions and concerns than answers and relief.



“I used to have back pain and cramps so bad I would need to lie down and use a heating pad. I just got my period today and didn’t notice any back pain, only minor cramping right before I got it. I’m loving the noticeable improvements that have started since using my Moon Bites.”


“I’m definitely seeing better results than when I tried my Naturopath’s recommendations. And much better results than when I tried birth control earlier in the year!”

“Is it bad I wish I could just snack on them? So yummy! Thanks for making seed cycling so easy.”

“I can finally quit birth control pills and trust my natural system to have a regular comfortable period.”
