e27 Liquid Collagen | Peptides for Skin & Joints

Discover e27 liquid Collagen peptides from Nature's Sunshine β€” supporting skin elasticity, hydration, hair, nails, and joints. Learn ingredients, usage & more.

Overview

What Is e27 Liquid Collagen and Why Does It Matter?

Collagen is the single most abundant protein in the human body, comprising roughly one-third of total protein content. It forms the structural foundation for skin, hair, nails, bones, joints, and connective tissue throughout the body. As we age, our natural Collagen production declines β€” and with it, skin elasticity, hydration, and the resilience of our joints and connective tissues.

e27 liquid Collagen delivers premium Collagen peptides in an 18-oz powder format that mixes effortlessly into any hot or cold beverage, smoothie, or recipe. These peptides are hydrolyzed β€” meaning the large Collagen molecule has been enzymatically broken down into smaller di- and tripeptide chains that studies show are absorbed into circulation and may reach target tissues like skin and cartilage, where they help support Collagen-producing cells known as fibroblasts.

This formula is NON-GMO, KETO-friendly, DAIRY-free, GLUTEN-free, and PALEO-friendly β€” a clean, effective source of pure protein designed to fit seamlessly into your daily wellness routine. It also includes electrolytes and trace minerals to round out its nutritional profile.

The tradition of consuming Collagen-rich foods stretches back millennia β€” from slow-simmered bone broths in traditional Chinese cuisine to the pot-au-feu of France and the beloved Vietnamese pho. Modern Collagen peptide supplements simply offer the same structural protein family in a convenient, well-studied format. If you have questions about whether a Collagen supplement fits your personal health goals, our naturopath is available for a free consultation.

What's inside

Key Ingredients

Collagen peptides β€” 17 g
These certified non-GMO, gluten-free, dairy-free, Keto-friendly, and Paleo-friendly Collagen peptides are hydrolyzed for enhanced absorption as di- and tripeptides rich in hydroxyproline. Collagen is the most abundant structural protein in the human body, rich in the amino acids glycine (33%), proline, and hydroxyproline (22%) β€” the building blocks that give Collagen its characteristic triple-helix structure and provide rigidity and resistance to stretching. Studies suggest these peptides may support multiple body systems:<br><br><strong>Skin Elasticity & Hydration:</strong> Multiple meta-analyses of randomized controlled trials demonstrate that oral hydrolyzed Collagen peptides significantly improve skin elasticity (SMD 0.61; 95% CI: 0.21–1.02) and hydration (SMD 1.25; 95% CI: 0.77–1.74) after 8–12 weeks. Fibroblasts recognize bioactive peptides such as Pro-Hyp and Gly-Pro-Hyp and may upregulate Collagen, elastin, and hyaluronic acid synthesis β€” factors closely associated with a more youthful skin appearance.<br><br><strong>Skin Aging & Wrinkles:</strong> Several randomized, double-blind, placebo-controlled trials demonstrate improvements in wrinkle depth, skin elasticity, and hydration. A systematic review published in the Journal of Drugs in Dermatology concluded that preliminary results are promising for both short- and long-term use of oral Collagen for skin aging, with no reported adverse events.<br><br><strong>Dry Skin:</strong> Research suggests Collagen peptides stimulate dermal fibroblast synthesis of new Collagen, elastin, and hyaluronic acid, reducing transepidermal water loss. A 12-week RCT (n=64, 1000 mg/day) showed significantly higher skin hydration values versus placebo at both 6 and 12 weeks.<br><br><strong>Hair Growth & Hair Loss:</strong> Collagen peptides provide amino acid substrates β€” notably proline, glycine, and hydroxyproline β€” that support keratin synthesis and dermal matrix integrity around follicles. A systematic review found Collagen peptides may improve the clinical appearance, strength, and brittleness of hair. Collagen constitutes the connective tissue sheath anchoring follicles, and its degradation with aging is associated with follicle miniaturization. A 2023 RCT using marine hydrolyzed Collagen combined with other nutrients showed improved clinical outcomes in patients with hair thinning conditions.<br><br><strong>Nail Strength:</strong> A 2017 open-label trial found that 2.5 g/day of bioactive Collagen peptides for 24 weeks increased nail growth rate by 12% and reduced the frequency of broken nails by 42% in women with brittle nail syndrome. Collagen peptides supply glycine and proline used in keratin synthesis and nail matrix support.<br><br><strong>Joint Health & Flexibility:</strong> A meta-analysis confirmed significant pain reduction in knee osteoarthritis patients receiving Collagen peptides versus placebo. A 2025 network meta-analysis of 4,599 KOA patients ranked Collagen among supplements with meaningful benefit. Research suggests 5–15 g/day taken at least 1 hour prior to exercise for over 3 months may aid in reducing functional joint pain and improving muscle recovery.<br><br><strong>Cartilage Health:</strong> Both hydrolyzed Collagen and undenatured type II Collagen have been studied in clinical trials. Hydrolyzed Collagen may be absorbed and incorporated into joint cartilage, with clinical evidence suggesting improved mobility and pain reduction. Multiple systematic reviews support its role in cartilage maintenance.<br><br><strong>Connective Tissue:</strong> Collagen is the primary structural protein in connective tissue β€” skin, cartilage, tendons, ligaments, and bone. A systematic review of 41 animal and human studies found that Collagen supplementation may benefit osteoarthritis and aid cartilage repair. Over 60 clinical studies support benefits for skin, joint, and musculoskeletal connective tissue.<br><br><strong>Bone Health:</strong> Preliminary research in postmenopausal women with osteopenia suggests Collagen supplementation may increase bone strength, density, and mass. One RCT assessed the effect of calcium and vitamin D supplementation with and without Collagen peptides on bone turnover. These findings are promising but require larger, independent replications.<br><br><strong>Sprain Recovery:</strong> Ligaments and tendons damaged in sprains are composed predominantly of type I Collagen. A 2026 systematic review found GRADE A evidence that Collagen supplementation combined with loaded training increases tendon cross-sectional area and stiffness, with improved ankle function reported as a beneficial outcome.<br><br><strong>Cellulite:</strong> A double-blind, placebo-controlled RCT of 105 women showed that oral bioactive Collagen peptides (2.5 g/day) over 6 months resulted in statistically significant improvement in cellulite, with improved dermal density and reduced skin waviness on thighs.<br><br><strong>Spinal Disc Support:</strong> Collagen β€” particularly type I and type II β€” is the primary structural protein of the intervertebral disc. Type II Collagen is progressively lost during disc degeneration, and supplementation has been studied for its ability to promote extracellular matrix protein synthesis in disc tissue.<br><br>Collagen is an incomplete protein (lacking tryptophan) and should not be used as a sole protein source. It is classified as Generally Recognized as Safe (GRAS) by the FDA, with no adverse effects reported across multiple systematic reviews even at higher doses.
Potassium chloride β€” 255 mg
Potassium is an essential mineral that functions in the body entirely as the monovalent cation K⁺. It plays a critical role in electrolyte balance, nerve signaling, muscle contraction, and cardiovascular function β€” making it a valuable complement to a Collagen supplement designed to support an active lifestyle.<br><br><strong>Electrolyte Balance & Cellular Function:</strong> Potassium powers the Na⁺/K⁺-ATPase (sodium-Potassium pump), discovered in 1957 by Nobel Prize-winning scientist Jens Christian Skou. This pump maintains the electrochemical gradients essential for action potentials in nerve and muscle cells. All cells expend a large fraction of their ATP β€” up to 70% in nerve cells β€” to maintain proper K⁺ and Na⁺ concentrations.<br><br><strong>Blood Pressure Support:</strong> The relationship between dietary Potassium and blood pressure is well documented. A meta-analysis of 22 RCTs reported that increased Potassium intake may reduce systolic blood pressure by 3.49 mmHg and diastolic by 1.96 mmHg in adults with raised blood pressure. The FDA has approved the health claim that diets containing foods that are a good source of Potassium and low in sodium may reduce the risk of high blood pressure and stroke.<br><br><strong>Cardiovascular Health:</strong> The landmark Salt Substitute and Stroke Study (SSaSS) β€” a cluster-randomized trial of 20,995 adults β€” demonstrated that Potassium-enriched salt significantly reduced rates of stroke (14%), major cardiovascular events (13%), and premature death (12%) over five years, with no increased risk of clinical hyperkalemia.<br><br><strong>Bone Health:</strong> Observational studies suggest that increased Potassium consumption from fruits and vegetables is associated with increased bone mineral density. One proposed mechanism involves Potassium's effect on acid-base balance β€” Potassium-containing foods provide precursors to bicarbonate ions that buffer acids, potentially preserving bone calcium content.<br><br><strong>Nerve & Muscle Function:</strong> The Na⁺/K⁺-ATPase maintains the negative membrane potential essential for nerve cells to generate and transmit action potentials. In skeletal muscle, Na⁺/K⁺-ATPase activity rapidly adjusts to changes in muscle use. If the resting membrane potential is not stabilized, muscles may not contract properly.<br><br>The Adequate Intake (AI) for Potassium is 4.7 g per day for adults. In healthy people with normal kidney function, the kidneys efficiently eliminate excess Potassium. Individuals with chronic kidney disease, those taking ACE inhibitors or Potassium-sparing diuretics, or those with certain medical conditions should consult a healthcare provider regarding Potassium intake.

Usage Guide

How to Take e27 Liquid Collagen

Collagen is odorless, tasteless and mixes easily into any hot or cold beverage, smoothie or food. It is easily integrated into any daily wellness program. Stir 1 scoop into any beverage (coffee, tea, water, fruit juice, etc.), or add it to your favorite recipes. Use daily for best results.

Consistency matters. Human studies on Collagen supplementation typically show results after sustained daily use. Research on skin elasticity and hydration often notes improvements within 8–12 weeks. For joint-related benefits, studies suggest that effects may begin to appear after three months or longer of regular use.

Because vitamin C is a required cofactor for the hydroxylation of lysine and proline residues during Collagen synthesis, pairing your Collagen with vitamin C-rich foods or beverages β€” such as citrus juice β€” may complement the formula's structural benefits.

Science & Tradition

The Story Behind Collagen Supplementation

The tradition of consuming Collagen-rich foods is truly ancient. In Traditional Chinese Medicine, Collagen-rich preparations were used to support skin elasticity, healthy aging, and joint strength. Almost ten centuries ago, the Benedictine abbess Hildegard von Bingen was already studying extracts from animal tissue and recognized their use for joint complaints. Indigenous cultures worldwide β€” from Native American tribes consuming boiled animal hides to African traditions using gelatin-rich preparations β€” independently developed Collagen-rich foods for nourishment.

Modern molecular biology has illuminated what these traditions supplied all along: a distinctive protein family with a unique amino acid profile, derived from connective tissue, in a form the body's own tissues can use as structural substrate. Today's hydrolyzed Collagen powders represent the contemporary contribution β€” the same building blocks in a format that dissolves in seconds rather than requiring hours of simmering.

The scientific literature now includes over 60 clinical studies assessing Collagen's effects on skin aging, musculoskeletal health, and beyond. Multiple systematic reviews and meta-analyses of randomized controlled trials support moderate evidence for skin hydration and elasticity, as well as moderate evidence for joint pain reduction in osteoarthritis. Research in areas like bone density, muscle recovery, and wound healing continues to show promising preliminary results.

It's worth noting that while the evidence is encouraging, many studies have been relatively short in duration (4–12 weeks), and optimal dosing regimens have not yet been definitively established. The safety profile, however, is well-documented β€” prolonged use is deemed safe with no adverse effects reported across multiple systematic reviews, even at higher doses.
