Sports Research Grass-Fed, Certified Paleo Friendly, Non-GMO and Gluten Free Collagen Peptides Powder, 'XL' Jar, 32oz - Unflavored

Awesome

The package arrived super fast. The product needs no introduction which is well reviewed and one the best Collagen Peptides available.

More expensive than 2 x 10 lb ones.

This is my second time ordered from this seller and they’re absolutely good of this. This collagen’s gives me better result than others.

Got the product in 2 days! Product is exactly as explained although there is quite a bit of unwanted space. The packaging is too big for how much product you get. Thst is the only thing I would comment on.

I've been using collagen peptides for 7 months, and this product for 3 of those months. Before i get into my review, here's some backstory so you know where I'm coming from. I'm a 45 year old male, 6ft, 205 lbs. I never drink, smoke, or take any drugs or pharma, and avoid artificial preservatives in my diet. I love to lift weights (6 hours per week, mix of light and heavy), and do 1 to 2 hours of cardio and yoga per week. I don't go hard on cardio or stretching, just what's needed to keep my heart and mobility healthy. I also get outside and hike for about an hour a day. I'm fortunate to have a job that involves talking by phone and have close access to a gym and trails, which is what makes all this possible. I limit my sitting time to no more than 5 hours per day. This is because 6 or more hours of sitting per day is shown to damage testosterone and vascular health in men. I started out with two mild problems: recurring inflammation and slow recovery in my right patellar tendon (the big one that goes over the knee), and above-optimal systolic blood pressure (around 135 to 145, while 110 to 120 would be better). I started taking collagen to improve recovery in my knee, and reduce the number of breaks I had to take from lifting. I tried several different ways of mixing it, including mixing with water, juice, and ice cream. This, and the other products I tried, mixed just fine. Ultimately I started mixing it into the oily fish I've been every morning for breakfast. It dissolves easily in just an ounce or two of room temperature water. The consistency goes from straight liquid water to a gel, about the consistency of hand sanitizer. This is true of every collagen product I tried. I noticed after about a month of taking collagen that my knee and elbow joints recover faster from heavy lifting sessions. Instead of needing 3 to 5 days for full joint recovery, I only need 2 to 3. I also noticed that the usual slight tendon soreness I had after a yoga session would be gone in a couple hours instead of lasting the rest of the day. As a result I can do more and harder workouts. I had previously gotten my blood pressure down from the upper 140s to upper 130s. Since making collagen part of my daily routine It's come down another 10 points, into the 125 to 130 range. Not perfect, but healthier. I don't know if it's the collagen per se, or just being able to exercise more frequently and intensely. It could also be the added omega-3s from the fish, or effects from cutting out artificial preservatives. Or less stress from staying single, lol. I didn't expect improvement in my skin, but that also happened. My skincare routine consists of washing with unscented baby shampoo, using unscented Aveeno during the day, and organic coconut oil at night. This has been my dirt-cheap routine for years. A family member I hadn't seen for 6 months came to visit last week. He told me I look younger than I did the last time I saw him. I've always looked somewhat young for my age, but even people I've known for a couple years are shocked now when I tell them I'm 45. In the past people would estimate my age at 3 to 7 years younger. Now they're estimating 10 to 15. This isn't a benefit I hoped for--recovery and mobility were and still are my objectives--but wow, I'll take it. Here's why I prefer this product over the others I've tried: Taste--it's virtually flavorless, which I vastly prefer Smell--I can't smell it Granularity--The granules are about the size of large sand particles. The few times I spilled it cleanup has been easy. Solubility--As I described above, the product dissolves quickly in a few ounces of water with little to no stirring. Price--This product is priced comparably to others, but because it's easy to work with and never unpleasant there's virtually no waste. The recommended dosage on the container is 20g per day. I take half that, 10g per day, and still am getting great results beyond wat I expected. I tried it at both 15 and 20 g per day, but didn't get better results. I of course recommend talking with your healthcare provider before taking any supplements and adjusting the dosage to what's safest and most effective for you. For cost, convenience, flavor, and effectiveness, this is best collagen product I've tried overall.

I started taking these collagen peptides in 2025 and I’m now on my 5th bottle and wow, what a difference! I’ve never had long nails in my life, but after finishing my 3rd bottle, I started noticing real growth. Now my nails grow so fast that I actually have to trim them regularly. They’re stronger, healthier, and don’t break like they used to. I’ve also noticed my skin looks more radiant and healthy, and my hair feels stronger too. The results didn’t happen overnight, but with consistency, they’ve absolutely been worth it. I also take other products from Sports Research and I truly love them all. The quality has been consistent, and I feel confident recommending this brand. I recommend this to everyone at the gym and honestly to anyone who wants healthier hair, skin, and nails. I’ll definitely keep repurchasing!

Sports Research Collagen Peptides is a great addition to my daily routine. The powder is unflavored and dissolves easily in coffee, smoothies, or water without clumping. Made with hydrolyzed Type I and III collagen, it supports healthy skin, hair, nails, and joints. I appreciate that it’s gluten-free and non-GMO, making it a clean and reliable supplement. Highly recommended for anyone looking to boost their collagen intake.
