California Gold Nutrition Marine Collagen Review
California Gold Nutrition CollagenUP® offers a premium hydrolyzed marine collagen peptide supplement designed to support overall health and well-being. This unflavored powder is formulated with marine-sourced collagen peptides, derived from wild-caught, deep-sea fish, ensuring a non-bovine and high-quality source. The collagen is enzymatically hydrolyzed, meaning it's broken down into bioavailable peptides to enhance absorption and utilization by the body. This advanced formulation also includes Hyaluronic Acid and Vitamin C, both from non-animal sources, which work synergistically to maximize the product's benefits. Collagen is a crucial structural protein that plays a vital role in maintaining the strength, elasticity, and flexibility of various connective tissues throughout the body. Regular supplementation with these collagen peptides can provide the essential building blocks necessary for the health of hair, skin, nails, joints, and bones. Specifically, the product promotes healthy bones and joints by supplying the primary structural protein required for their integrity. For hair, skin, and nails, the inclusion of Hyaluronic Acid and Vitamin C aids in hydration, repair, and provides antioxidant protection, contributing to a more youthful and radiant appearance. The product emphasizes enhanced bioavailability, ensuring that the body can optimally absorb and benefit from the nutrients. California Gold Nutrition is committed to trust and confidence, with its products independently tested at ISO-certified labs for authenticity, purity, and potency, as certified by NSF International in 2022. This commitment extends to the product's composition, which is free from GMOs, gluten, artificial sweeteners, colors, and flavors, making it suitable for a wide range of dietary preferences. The 7.26 oz (206 g) container provides a convenient way to integrate this comprehensive collagen support into your daily routine, helping to maintain the structural integrity and vitality of your body's tissues.

The main ingredient, marine collagen peptides, is present at 5 grams a day, a full dose. Large reviews of randomized trials found that collagen taken by mouth improved skin hydration and elasticity more than placebo [1], and that about 90 days of use, mostly in women, also reduced wrinkles [2]. In one trial, women aged 35 to 55 taking 2.5 or 5 grams daily for 8 weeks had better elasticity, though moisture did not change significantly [3]. A newer review found collagen beat placebo in most trials but noted that most had a high risk of bias [4]. Hyaluronic acid is included at 60 milligrams, and it is unclear how this compares with studied doses. A review of placebo-controlled trials found that hyaluronic acid taken by mouth improved hydration, elasticity and wrinkle depth [5]. However, a trial adding 30 milligrams to collagen and vitamin C found no extra benefit over collagen alone [6]. Vitamin C is present at 90 milligrams, but its strong support for wrinkles comes from creams and serums applied to the skin, not from capsules or powders taken by mouth [7][8]. So these skin results do not directly apply to this product. Animal and cell studies are never counted.

Biohacker Summary
Members Only10 of 10 recommend it
10 of 10 biohackers on our panel recommend it
Collagen is the main ingredient, and most of the panel is positive on it: three recommend it, three use it, and one stopped taking it. People take it for skin, joints, connective tissue, muscle and recovery, and one panelist's reasoning is that it sends signals that help the body build its own collagen. The doses given are 2.5 to 5 grams a day of hydrolyzed collagen for at least 8 weeks, and 10 grams in the morning, with one panelist mixing collagen peptides into a pudding. Cautions came from one panelist who says collagen alone will not repair a damaged gut wall and another who says it is less effective for muscle than whey, and one more has stopped taking it. Vitamin C, sodium and hyaluronic acid are smaller ingredients in this product.

- Dr. Rhonda Patrick's daughter chugs an Emergency fizzy drink in the morning to ensure she gets some vitamin C and micronutrients before school.
- Choosing a multivitamin that includes lutein and zeaxanthin ensures you get meaningful amounts every day.
- Notes that ~35% of Americans are low in vitamin C.
- Recommends increasing vitamin C intake if concerned about skin aging, noting it is an essential cofactor for collagen synthesis.
- Suggests avoiding a multivitamin if it contains biotin before a testosterone blood test to prevent confounding results.
- Multiple randomized controlled trials show older adults taking a standard multivitamin (like Centrum Silver) had measurable improvements in processing speed, cognition, and episodic memory.
- Currently takes the Pure Encapsulations O.N.E Multivitamin.
- Uses Hydrolyzed Collagen Peptides as a source of glycine and proline to support connective tissue and skin health.
- Rhonda's current supplement routine includes Vitamin C.
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.
- Peter discusses lifestyle factors impacting blood pressure, including sodium.
- Mentions that dietary sodium guidelines are around 5 grams per day, but some newer information suggests 8 to 10 grams might be acceptable before concern.
- Recommends vitamin C as an important molecule for skin, noting its role as a precursor for collagen synthesis, a powerful antioxidant, and a regulator of complexion for even skin tone.
- Tried a vitamin C serum mixed with ferulic acid but stopped using it because she hated the smell. She notes that topical application of vitamin C far exceeds the levels achievable by ingestion for skin benefits.
- States that vitamin C deficiency is associated with an elevated risk of cataract, but supplementation to supranormal levels has not been shown to protect against cataract formation.
- Mentions the elimination of scurvy through the work of James Lind and the eventual understanding that it was due to vitamin C, initially thought to be just citrus.
- Warns that for individuals with gene polymorphisms making them sensitive to salt, a higher sodium intake can significantly increase blood pressure.
- 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.
- Notes that hyaluronic acid injections are doing better than cortisone for joint pain, and that combining hyaluronic acid with PRP seems more effective than other treatments, though not astronomically so.
- Mentions that hyaluronic acid injections are another treatment option that performs better than cortisone over a year.
- Says he would give hyaluronic acid in the hip, even though it's not FDA approved for that application, as it can be used off-label and some studies suggest it can help.
RAL Summary
Members OnlyTier 2 for Younger-Looking Skin for Women
Tier 2 because the full 5 gram dose of marine collagen peptides matches trials where two large reviews, the biggest with 1,721 people, found better skin hydration and elasticity than placebo [1][2]. Customer ratings are also strongly positive.
Where the evidence disagrees: 2 of the 47 human studies found no effect.

Body systems: Skin
Combine with: To enhance the benefits of marine collagen, consider combining it with Vitamin C, which is crucial for collagen synthesis. Hyaluronic acid can further support skin hydration and joint lubrication, working synergistically with collagen. Silica and MSM are also excellent additions for strengthening connective tissues, hair, skin, and nails, while supporting overall joint health. For comprehensive joint support, glucosamine and chondroitin can be beneficial alongside collagen.
Possible side effects: Collagen studies reported no side effects or adverse events, and vitamin C products had few side effects. The product contains fish, so people with fish allergies should avoid it.
