Pure Certified Grass-Fed Collagen

CERTIFIED GRASS-FED COLLAGEN PEPTIDES (SOLUGEL®) (10 grams)

CERTIFIED GRASS-FED COLLAGEN PEPTIDES (SOLUGEL®) (10 grams)

Contains 10 grams of SOLUGEL® certified grass-fed collagen peptides—the only truly certified grass-fed collagen on the market. Unlike competitors who make unverified grass-fed claims, our collagen is certified by LIAF Control in collaboration with the American Grassfed Association. This certification guarantees that our collagen comes from cattle raised outdoors on pasture 365 days per year with free access to fresh grass, air, land, and water. It also ensures the animals are born and raised on family farms/ranches—rather than big multinational corporate operations. Never given hormones, antibiotics, or anabolic steroids, our cattle are continuously subject to veterinary supervision and raised according to the highest ethical standards.

What sets our collagen peptides apart is their optimal molecular weight (average 2 kDa). At this size, the peptides dissolve completely clear in liquids, are rapidly absorbed in the digestive tract, and are more bioavailable. This low molecular weight prevents the digestive discomfort that some people experience with other collagen supplements and ensures that the active peptides reach your tissues where they can provide maximum benefit.

Why Choose Bio-Avail Collagen+?

Bio-Avail Collagen+ contains SOLUGEL® certified grass-fed collagen peptides. While most grass-fed collagen claims are unregulated and unverifiable, our collagen is officially certified by a third-party organization (LIAF Control in collaboration with the American Grassfed Association). This certification ensures our collagen comes from cattle that spent 100% of their lifetime on grass and pasture.

The science-backed 10-gram daily dose aligns perfectly with clinical studies showing benefits for skin, joints, and overall health. Our collagen is precisely processed to achieve an optimal 2 kDa molecular weight, which maximizes absorption and bioavailability. This means it dissolves crystal clear in any beverage and is gentle on your digestive system.

Unlike other collagen supplements that contain fillers, flavors, sweeteners or questionable additives, Bio-Avail Collagen+ contains just one clean ingredient: certified grass-fed collagen peptides. Nothing else. This pure approach ensures you get all the benefits without any unwanted substances.

Good For You—And the Planet

You can't have healthy humans without a healthy planet. That's why Adapt Naturals is working toward zero plastic and landfill waste in our supply chain.

In the fall of 2023, we started transitioning our packaging to 100% compostable, stand-up pouches. 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!

Our sustainable packaging initiative will prevent over 120,000 plastic bottles from ending up in a landfill or the oceans. Thank you for being part of the solution and helping Adapt Naturals protect the beauty of our natural environment!

Your Questions Answered

Mix one scoop (10g) into any hot or cold beverage. It dissolves completely clear with no taste, making it perfect for coffee, tea, smoothies, or plain water. For optimal results, take daily. You may notice benefits within 4-8 weeks of consistent use, with continued improvements over 3-6 months.

The term grass-fed is not regulated in supplements, meaning many companies can make this claim without verification. Our collagen is different—it's certified by LIAF Control, a member of the American Grassfed Association. This certification guarantees that the cattle spent 100% of their lives on pasture, eating grass, with no hormones or antibiotics, and with full traceability back to the multigenerational, family source farms.

Three key differences: 1) It's the only certified grass-fed collagen on the market; 2) It has a precise ~2 kDa molecular weight for optimal absorption and bioavailability; and 3) It contains a full 10-gram dose, which research shows is most effective for results. Plus, it's a clean-label product with absolutely no fillers, sweeteners, or additives.

The ~2 kDa molecular weight of our collagen peptides makes them more bioavailable and easier to digest. This means better absorption, reduced digestive discomfort, and greater efficacy. Our collagen also dissolves completely clear in liquids—no clumps or gritty texture—making it more pleasant to consume.

Bio-Avail Collagen+ is gluten-free, dairy-free, soy-free, and contains no added sugars, fillers, or artificial ingredients. However, it is derived from bovine sources, so it is not suitable for vegetarians or vegans.

While individual results vary, studies show benefits can be observed in different timeframes: improvements in skin elasticity within 4-8 weeks, joint comfort within 3-6 months, and exercise recovery benefits within 4-12 weeks. Consistency is key—daily use will yield the best results.

Research has shown that collagen peptides can significantly reduce appetite and subsequent meal energy intake compared to other proteins. This satiety effect is thought to be related to collagen's specific amino acid profile, which may influence hunger hormones and metabolic signals. Some studies showed a 20% reduction in food intake following collagen consumption.

Yes, all Adapt Naturals products, including Bio-Avail Collagen+, 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.
