California Gold Nutrition

This product delivers 5 grams of creatine monohydrate per serving, a clinically validated dose shown to enhance short-duration, high-intensity exercise performance. Creatine monohydrate is the most researched and effective form of creatine, with strong evidence supporting its role in increasing muscle phosphocreatine stores and improving resistance exercise capacity.

This supplement is formulated around hydrolyzed marine collagen peptides as the primary active ingredient, supported by a prebiotic fiber blend and a leucine-enriched essential amino acid complex. The product targets skin and joint health, gut function, and muscle protein synthesis support. While the collagen dose is clinically relevant, the amino acid and prebiotic components serve as functional adjuncts.

CollagenUP® is a marine collagen peptide supplement designed to support skin and joint health. The primary ingredient, hydrolyzed marine collagen peptides (5 g per serving), is supported by hyaluronic acid and vitamin C to enhance collagen synthesis and tissue hydration. While the collagen dose is below typical clinical levels, it is formulated for daily use as part of a broader nutritional strategy.

Gold C® is a high-dose vitamin C supplement providing 1,000 mg per serving, formulated to support immune function, antioxidant defense, and collagen synthesis. The dose aligns with clinically studied levels shown to reduce the severity and duration of respiratory infections, particularly in individuals under physical stress or with low baseline vitamin C status.

This supplement combines multiple carotenoids—lutein, lycopene, astaxanthin, and vitamin A—with supporting antioxidants to target eye health, oxidative stress reduction, and immune modulation. The primary ingredients—lutein, astaxanthin, and lycopene—are included at doses aligned with clinical research, particularly for macular pigment enhancement and antioxidant activity.

This BCAA powder delivers a 2:1:1 ratio of L-Leucine (2.5 g), L-Isoleucine (1.25 g), and L-Valine (1.25 g) per serving, with L-Leucine as the primary active ingredient driving muscle protein synthesis. The formulation is designed to support exercise recovery, muscle maintenance, and performance, aligning with evidence-based dosing for active individuals and older adults at risk of sarcopenia.

This liver-supportive dietary supplement centers on milk thistle extract (silymarin), a well-researched hepatoprotective agent with antioxidant, anti-inflammatory, and antifibrotic properties. The formulation includes complementary botanicals such as dandelion, artichoke, curcumin, ginger, and BioPerine® to enhance bioavailability and broaden metabolic and anti-inflammatory support. While the primary ingredient is dosed below high-end therapeutic levels, it falls within the clinical range for general liver support when taken as directed.

This supplement combines two amino acids—L-Glutamine and L-Leucine—each dosed at 2.5 g per serving. L-Glutamine supports gut barrier integrity and immune function, particularly under catabolic stress, while L-Leucine acts as a key regulator of muscle protein synthesis, making it relevant for muscle maintenance and sarcopenia prevention. Both ingredients are in free-form powder, supporting rapid absorption.

This supplement features a proprietary blend of Angelica gigas, Cynanchum wilfordii, and Phlomis umbrosa (EstroG-100), a clinically studied herbal complex shown to reduce menopausal symptoms such as hot flashes, vaginal dryness, and mood disturbances. The formulation is designed to provide non-hormonal support, making it a potential alternative for women seeking relief without estrogenic effects on reproductive tissues.

This supplement combines L-Glutamine and L-Leucine, two amino acids with distinct roles in gut health and muscle protein synthesis. L-Glutamine is the primary ingredient based on naming and functional focus, supporting intestinal barrier integrity and immune function. While both ingredients are included at moderate doses, neither reaches the typical clinical range for their most evidence-backed indications when taken at one serving per day.

NMN Flavonoid Complex is a dietary supplement featuring nicotinamide mononucleotide (NMN) as the primary active ingredient, formulated to support cellular energy metabolism and healthy aging through NAD+ biosynthesis. The addition of flavonoids apigenin and dihydroquercetin provides antioxidant and anti-inflammatory support, though their doses are sub-clinical and serve a secondary role.

Omega-3 Premium Fish Oil by California Gold Nutrition provides 180 mg of EPA and 120 mg of DHA per serving, derived from fish oil. These omega-3 fatty acids support cardiovascular and cognitive health and contribute to the resolution of inflammation. The formulation aligns with typical over-the-counter supplement profiles, though higher doses may be needed for specific clinical outcomes.

NMNH is a dietary supplement featuring dihydronicotinamide mononucleotide disodium salt, a reduced form of NMN and precursor to NAD+, a coenzyme involved in cellular energy metabolism and aging processes. While the primary ingredient effectively raises NAD+ levels in clinical studies, evidence for functional health benefits such as improved glucose metabolism or physical performance remains limited and inconsistent. The product contains a minimal amount of sodium, which does not contribute significantly to daily intake or therapeutic effects.
