Sports Research Marine Collagen Unflavored Review
Sports Research Marine Collagen is presented as a morning ritual that mixes into your favorite beverage. The product is hydrolyzed so it combines easily and is said to be more readily absorbed. The page explains that collagen is the most abundant protein in the human body, but that the body produces less of it as we age, which can contribute to wrinkles, joint pain and other concerns. The listing states that having enough collagen supports healthy hair, skin, and nails, as well as joints. The collagen is sourced from 100% Barramundi and Red Snapper skin and scales that would otherwise be discarded. The page describes it as a pescatarian-friendly alternative to traditional bovine collagen. Each scoop is said to contain 10 grams of low molecular weight Types I and III collagen peptides, with 18 amino acids including glycine, proline, and hydroxyproline, plus 9 grams of protein and 35 calories per serving. The product is marketed as mixing easily into everyday routines and as supporting healthy hair, glowing skin, healthy nails, and a radiant, youthful look. The page highlights that the collagen is sourced from wild-caught fish. The brand states it is dedicated to quality and uses the best ingredients so customers can have peace of mind. The product is listed as Informed Choice certified, IGEN Non-GMO Tested, cGMP compliant, third party tested, gluten-free, and pescatarian-friendly. The brand says it closely partners with trusted manufacturers to source high quality ingredients from around the world. The listing is for the 12 oz unflavored size, which provides 34 servings, and it offers a one-time purchase option as well as a subscribe and save option at 15 percent off. The page also includes a frequently asked questions section covering protein per serving, collagen types, pescatarian status, benefits, amino acid count, calories and Non-GMO status, along with suggested related products.

This powder gives 10 grams of hydrolyzed marine collagen peptides a day, a full dose within the range used in skin studies. A 2023 review that pooled 26 randomized trials with 1,721 people found that collagen taken by mouth improved skin hydration and elasticity more than placebo [1]. A 2021 review of 19 trials with 1,125 people, almost all women, found that about 90 days of collagen reduced wrinkles and improved elasticity and hydration compared with placebo [2]. A 2019 review of 11 placebo-controlled trials using 2.5 to 10 grams daily for 4 to 24 weeks found better elasticity, hydration and skin collagen density, with no reported harms [3]. In a 2018 trial, 64 people taking 1,000 milligrams daily for 12 weeks had better hydration, fewer wrinkles and better elasticity than placebo [4]. In a 2014 trial of 69 women aged 35 to 55, 2.5 or 5 grams daily for 8 weeks improved elasticity, but moisture did not change significantly [5]. A 2026 review of 25 trials found collagen beat placebo for wrinkles in 9 of 10 trials, elasticity in 10 of 13 and hydration in 10 of 15, though most trials had a high risk of bias [6]. Animal and cell studies are never counted.

Review Totals and Summary
Members Only4,213 reviews · 88% positive
Across the stores, Sports Research Marine Collagen powder carries about 4,072 ratings, and buyers are mostly positive. They praise how easily it mixes and how little taste it has, while results are mixed or slow to show. One page averages 4.5 out of 5, and one buyer reports that the product has changed for the worse. **What buyers say it did for them:** Only one written review reports clear benefits: stronger, healthier joints and better hair and nails. "Benefits are stronger and healthier joints and an improvement in the quality of my hair and nails." Others are still waiting. One expects to need about three months: "keep taking it for three months to see results." Store summaries say opinions on results are mixed. One buyer was unsure after two months, and another had not yet seen changes in hair or nails. Some report no side effects and say they absorb it well. **What they complain about:** The sharpest complaint is that quality has slipped. One reviewer says the powder "is now extremely fine making it very difficult to dissolve," with a bitter aftertaste, and will not buy again. This is the only complaint of its kind on the page where it appears. The Sports Research site also has a comment that it is not fully unflavored: it changes the taste of what it is mixed into, though not in a fishy way. Several buyers are unsure yet whether it works. **Taste, smell and form:** This is the most repeated praise. Reviewers say it has "no strong taste, mixes well" and is "easy to add to coffee or drinks without ruining the flavor." Another says there is "Not a taste to detect on a smoothie or coffee." Store summaries add that many find no aftertaste and only minimal smell, with no fishy note, and that it dissolves quickly in cold liquids. One buyer finds it mixes best in lukewarm water and is not gritty. Another who had tried bovine collagen found this far more palatable. It is a powder, so pill size does not apply. **Value for money:** No reviewer or summary discusses price or value, so there is nothing to report here. Some buyers say they would buy again or plan to keep taking it, and others point to third-party testing, accurate dosing and collagen type as reasons they chose it. **Who it suits and who it did not:** It seems to suit people who want a collagen they can stir into coffee, smoothies or other drinks without noticing it. It also suits people who dislike fishy marine products or care about ingredient testing. One reviewer called it the best marine collagen they found after hours of research. It suits less well anyone expecting fast, visible results, since several are still waiting. It also suits less well anyone who wants a product with no flavor at all, or who gets a batch like the fine, bitter one described above. Reviews of other forms of this product, such as gummies or capsules, were left out; this summary covers the powder only.
Biohacker Summary
Members Only10 of 10 recommend it
Collagen is the only ingredient the panel discussed, and the group leans toward using or recommending it. Of the ten, three recommend it and four say they take it, two are neutral, and one has stopped. People take it for skin elasticity, joints, tendons and other connective tissue, with some also citing gut care, sleep or muscle. Doses given were 2.5 to 5 grams a day of hydrolyzed peptides for at least eight weeks for skin, and 10 to 15 grams for others, often taken 30 to 60 minutes before exercise and paired with vitamin C, or in the morning, in coffee or before bed. Cautions came from several voices: collagen is a weak protein for building muscle and should be paired with another protein, it won't repair a damaged gut on its own, and one panelist no longer takes it.

- Uses Hydrolyzed Collagen Peptides as a source of glycine and proline to support connective tissue and skin health.
- Dr. Rhonda Patrick, who was previously unconvinced, now recommends hydrolyzed collagen powder prophylactically for connective tissue and ligaments, especially if someone has a soft tissue injury history, to be taken 30 to 60 minutes pre-exercise with 50 milligrams of vitamin C.
- Discusses whether collagen can actually strengthen tendons.
- Warns that collagen is a suboptimal protein choice for those engaged in resistance training and wanting to improve skeletal muscle protein synthesis because it does not significantly enhance muscle protein synthesis or muscle connective protein synthesis at rest or after exercise.
- Discusses whether collagen supplementation benefits the skin.
- Suggests that collagen might be more relevant for tissues like cartilage, bone, tendons, ligaments, and skin, which are more than 80% collagen, especially after surgery where collagen structures need to be renewed.

- Dr. Patrick adds a quarter cup of hydrolyzed collagen powder to her smoothie, primarily for the non-essential amino acids like glycine and proline, which are necessary for collagen synthesis and wound healing.
Peter Attia · Collagen · neutral
- Explains that collagen has a much lower quality amino acid composition than whey and tends to be rich in only a handful of amino acids like glycine and proline, making it less effective for muscle protein synthesis.
- Advises that collagen protein is not a very complete protein and suggests supplementing it with something else if consumed, despite his wife's preference for it.
- Says that based on current data, there is no benefit in myofibrillar or muscle connective tissue protein synthesis using collagen versus whey or casein, especially in exercising individuals. He warns that using collagen as a sole supplemental protein source compromises myofibrillar muscle protein synthesis due to its poor amino acid balance.
- States that as a scientist, he hasn't seen evidence that collagen leads to greater connective tissue protein synthesis rates in muscle, but if he were recovering from a hip or knee injury, he would take a protein supplement with some collagen to ensure enough glycine and proline for ligaments, tendons, bone, and cartilage.
- Recommends collagen supplements, in either pill or powder form, for hair, skin, nails, bones, and for putting on and maintaining healthy muscle, as it's difficult to get enough from diet alone.
- Suggests throwing some collagen into the diet as a source of glycine.
- Uses collagen as a classic example of an orally taken peptide that is regulated as a supplement, noting it's taken for its amino acid breakdown rather than the whole peptide.
- States there is no good evidence that collagen supplements marketed for "gum regrowth" can restore a receded gumline without surgery, though some may improve symptoms or slow progression.
RAL Summary

More Details
Members OnlyBody systems · Combine with · Possible side effects
Body systems: Skin, Connective tissue
Combine with: For skin and collagen support, pair it with vitamin C (500 mg or more), which is needed for collagen synthesis, plus hyaluronic acid, biotin, and a skin-supportive antioxidant such as astaxanthin or vitamin E. If the goal remains muscle building, add a complete protein such as whey or a plant protein blend with enough leucine, creatine monohydrate (3-5 g daily), and vitamin D3 with magnesium. Take collagen with vitamin C about 30-60 minutes before resistance training if you want to support tendon and connective tissue health. Use it alongside, not in place of, a complete protein source.
Possible side effects: Studies reported no side effects or adverse events. One buyer described a batch that was hard to dissolve with a bitter aftertaste, and the product contains fish, so people with fish allergy should avoid it.
