They’re made from cellulose (wood pulp) and are free of PLA, BPA, PFAS, phthalates, and other harmful chemicals. They’re printed with non-toxic, compostable ink. The pouches are so clean and biodegradable that you can put them in your backyard or curbside compost bin!

Your Questions Answered

The Fertility Stack takes a comprehensive approach to optimize reproductive wellness and prepare for a healthy pregnancy. Bio-Avail Multi provides a complete prenatal vitamin and mineral formula to nourish reproductive cells and support fetal development. Bio-Avail Organ delivers targeted nutrients from reproductive tissues to balance hormones and promote optimal function. And Bio-Avail Colostrum+ supports immune balance and gut health, which are crucial for a healthy conception and pregnancy.

Yes, the Fertility Stack is designed to support both male and female reproductive health. While some ingredients are specifically targeted towards women (e.g., prenatal vitamins), many of the nutrients and compounds in this stack are equally important for male fertility. Optimal nutrition, hormone balance, and immune function are crucial for reproductive health in both partners.

Ideally, both partners should start taking the Fertility Stack at least 3-6 months before trying to conceive. This allows time for the nutrients to optimize egg and sperm quality, regulate hormone function, and support overall reproductive health. However, even starting one month before conception can provide significant benefits. It's also important to continue taking the stack—after confirming with your healthcare provider that it’s safe and appropriate for you—throughout pregnancy to support fetal development and maternal health.

If you have a pre-existing reproductive health condition (e.g., PCOS, endometriosis, low sperm count), the Fertility Stack can often provide significant benefits by optimizing nutrient status, balancing hormones, and supporting overall reproductive function. However, it's always best to consult your healthcare provider before starting any new supplement regimen, especially if you are undergoing medical treatment for your condition. Your provider can help you determine if the Fertility Stack is right for you and guide you on the best dosage and timing.

We always suggest checking with your healthcare provider before beginning a new supplement routine, and this is especially true for pregnant women. That said, the ingredients in this stack—vitamins, minerals, and phytonutrients in Bio-Avail Multi, organ meats in Bio-Avail Organ, and colostrum, lactoferrin, and beta-glucan in Bio-Avail Colostrum+—have been studied for their benefit in pregnant/lactating populations, and so we have no reason to believe that it is unsafe for these populations to consume them. Bio-Avail Multi provides a complete prenatal vitamin and mineral formula to support fetal development and maternal health. Bio-Avail Colostrum+ helps strengthen immune defenses and maintain a healthy gut microbiome, which is crucial for a healthy pregnancy. Bio-Avail Organ contains heme iron, active B vitamins, and many other nutrients that support a healthy pregnancy.
