What’s the difference between the circadian rhythm and the infradian rhythm?

The circadian rhythm is a biological rhythm that syncs our internal body systems such as wakefulness to the 24 hour day rhythm of the sun. The infradian rhythm refers to cycles that last longer than this, such as the monthly lunar cycle of menstruation.

How do I know if I need cycle support?

Anyone with a menstrual cycle is on an “infradian” or lunar rhythm and experiences rhythmic and predictable fluctuations in their hormone and inflammatory blood levels. These fluctuations can affect mood and physical symptoms and cycle support can be beneficial. 

Additionally, those interested in syncing their own natural rhythms to the lunar rhythms may experience health benefits. 

What are cyclic symptoms?

Cyclic symptoms are recurring symptoms that follow a consistent pattern. Women’s hormones and chemistry fluctuate throughout the month in a rhythmic way. Most menstruating women experience symptoms characteristic of each of the four phases of the menstrual cycle. 

What is menstrual phase syncing?

Menstrual phase syncing is aligning nutrition, exercise and activity with the four phases of the menstrual cycle - menstrual, follicular, ovulatory and luteal - to optimize mood and energy.

What is supplement cycling?

Supplement cycling is taking certain supplements for a specific period of time, and then not taking them for a specific period of time. Each Lunar Sync pack cycles supplements based on the four phases of the menstrual cycle, with the changing formulae rotating vitamins and herbs in and out, based on the body’s needs for that phase. For example, iron is only included in the capsules taken during phase 1 of the menstrual cycle. 

What are natural rhythms?

Natural rhythms are naturally occurring external and internal rhythms that guide all that we do. Our daily and monthly cycles affect our body’s chemistry, physiology and metabolism. These rhythms guide energy, moods and sleep. When our rhythms are in sync, we are in flow and at ease – we are more energetic, productive, mindful, connected and content. 

Why is Lunar Sync paused?

Lunar Sync is in a restorative pause while we reassess next steps for the formulation and future production. This allows space to reflect, refine, and explore what a next chapter may look like.

Can I continue taking my current supply?

Yes. Lunar Sync remains safe to use. Natural supplements gradually shift in potency over time, and your existing supply still meets the standard Dr. Sari feels confident standing behind.

When will Lunar Sync be available again?

There is no set timeline. We’ll share updates with subscribers as soon as there is clarity on what’s ahead.

Will I still receive my subscription?

As a thank you for your support, active subscribers will receive one final shipment with a complimentary 15-month supply (15 total packs) to support their cyclical health during this pause.

Are there alternatives I can use in the meantime?

Yes. Dr. Sari has curated a collection of clinically trusted supplements that support hormonal balance, menstrual cycle health, and overall wellbeing. You can explore those options here.

Is this pause permanent?

This pause is an intentional moment to evaluate the best path forward. We will keep subscribers updated as the future of Lunar Sync takes shape.
