Frequent Questions

How do I know if Iron BioSeries™ is right for me?

If you're dealing with low iron levels or have been advised to take a high-dose iron supplement, our Iron BioSeries™ may be the right choice for you. Iron BioSeriesTM provides 60mg of elemental iron per serving, it's formulated for individuals with low iron levels and is not intended for routine daily supplementation. As with any new supplement, we recommend checking in with your healthcare provider to make sure that Iron BioSeries™ is right for you.*

How does the BioSeries™ technology work?

The world’s first BioSeries™ three-in-one tablet in capsule technology is a breakthrough innovation designed to optimize our formula delivery through customized release profiles.

For Iron, BioSeries™ technology combines 60mg of iron in instant and extended release tablets, designed to release with the body’s natural hepcidin levels in mind. Iron BioSeries™ is formulated with intermittent dosing and BioSeries™ technology, designed to support optimal iron absorption and minimal GI discomfort.*

How and when should I take Iron BioSeries™?

Take Iron BioSeries™ every other morning on an empty stomach. This schedule is formulated with the body’s natural hepcidin levels in mind, designed to support optimal iron absorption and minimal GI discomfort.*

Can I take Iron BioSeries™ if my multivitamin also has iron in it?

Yes! Iron BioSeries™ is specifically formulated for individuals with low iron levels, so it can be safely taken alongside your regular multivitamin to help support iron intake. That said, we recommend checking in with your healthcare provider to make sure that Iron BioSeries™ is right for you.*

Is Iron BioSeries™ safe for pregnancy and nursing?

Yes! With emerging research suggesting that over 80% of women may be at risk of experiencing low iron levels during their third trimester, Iron BioSeries™ was thoughtfully formulated to meet these specific needs. Its intermittent dosing is designed to support optimal absorption and minimal GI discomfort, so you can focus on getting the iron you need.†*

†Consult your health care practitioner before using this product if you are pregnant or nursing, using medications or have a medical condition.

Why is Iron BioSeries™ designed to be taken every other day?

Research shows that spacing out your doses by taking them every other day supports iron absorption because it allows time for the body's hepcidin levels to return to baseline before the next dose is consumed.*

What purchase and delivery options does Ritual offer?

1-Month Subscription: Enjoy automatic delivery of a 30-day supply every 30 days with free shipping for convenient, consistent replenishment. All subscriptions renew automatically, but you’re always in control. You can pause, skip, change your delivery date, or cancel anytime from your Account Page.

What kind of testing do you do?

One of our favorite questions to answer. We aim to go above and beyond when it comes to testing, because we believe you deserve to know what you’re putting in your body and why. Third-Party testing every batch of Iron BioSeries™ isn’t a requirement, but at Ritual we strongly believe it should be, which is why we do our own rigorous testing on each batch. Each batch of Iron BioSeries™ is Third-Party tested to ensure our products are compliant with regulations and guidelines for heavy metals and microbes and to help assure the quality and safety of our products.

I’ve always struggled with low iron so I will have blood work done again in a few months and I’m looking forward to seeing how this has helped me improve. Easy to take a great flavor. I’ve been very happy and satisfied.
