Our whole, unprocessed colostrum has a richer, creamier texture that may require a bit more mixing than typical supplements. We recommend using a handheld frother or blender for the smoothest consistency. The natural dairy aroma and golden color are signs you're getting authentic, minimally processed colostrum.

You can mix Bio-Avail Colostrum+ into both foods and beverages! Recent research suggests that for generally healthy individuals, taking colostrum with food does not significantly impact its absorption or benefits. Feel free to stir it into yogurt, oatmeal, smoothies, or other foods and drinks.

However, we advise against mixing Bio-Avail Colostrum+ into hot beverages like coffee or tea, as high temperatures can degrade the delicate immunoglobulins and other beneficial proteins. Stick with room temperature or cold liquids and foods for optimal results.

If you have diabetes, metabolic issues, or simply find you get better results taking it on an empty stomach, mixing Bio-Avail Colostrum+ with 6-8 ounces of room-temperature water and drinking it 30 minutes before or 2 hours after a meal is still a great option.

We source our colostrum from grass-fed, pasture-raised farms across the US. It's free from pesticides, heavy metals, antibiotics, and hormones. And it's cold-processed to keep the fragile immunoglobulins and other nutrients intact.

While colostrum does contain a minimal amount of lactose, it is generally well-tolerated by people who are sensitive to lactose. We recommend speaking with your healthcare provider before supplementing with Colostrum+ if you are sensitive to lactose.

Yes, all dairy products (including colostrum) contain casein. We do not recommend taking Bio-Avail Colostrum+ if you have a casein sensitivity or allergy.

No. The pasture-based farms we source colostrum from understand the importance of colostrum to developing calves. The calves are fed 2–4 liters of colostrum shortly after birth. New mothers often produce more than 12 liters, so the farmers can harvest this excess colostrum without harming the calves.

Lactoferrin is naturally present in colostrum at 0.3-0.5%. This equals 3-5 mg per gram, or 7.5-12.5 mg per our 2.5 gram serving. However, Bio-Avail Colostrum+ also includes 100 mg of pure lactoferrin—yielding a total of 107.5 to 112.5 mg of lactoferrin per serving. This is far higher than other colostrum products that do not contain additional lactoferrin.

Yes, all Adapt Naturals products, including Bio-Avail Colostrum+, undergo rigorous third-party testing for purity and potency. Most importantly, we transparently share these results with our customers by posting Certificates of Analysis (CoAs) and test results on our website. This level of openness is almost unheard of in the supplement industry. It allows you to see exactly what's in the product you're putting into your body.
