The Science Behind Her Eir
The Science Behind Her Eir
Most supplement brands ask you to take their word for it. We'd rather show you the research and let you decide for yourself. Every ingredient in Her Eir is there for a reason, backed by real clinical evidence, and formulated at levels informed by that evidence. Here's the science.
Hydrolysed Bovine Collagen
What it does: Hydrolysed collagen provides collagen-derived peptides and amino acids that the body can use in connective-tissue processes.
What the evidence shows:
- A meta-analysis of 26 randomised controlled trials (1,721 participants) found hydrolysed collagen supplementation was associated with significant improvements in skin hydration and elasticity compared with placebo. Effects of Oral Collagen for Skin Anti-Aging: A Systematic Review and Meta-Analysis, PubMed
- A separate meta-analysis of 19 clinical trials (1,125 participants, 95% women, aged 20 to 70) found favourable effects on skin hydration, elasticity and wrinkles, with benefits generally observed after around 90 days. Effects of Hydrolyzed Collagen Supplementation on Skin Aging: A Systematic Review and Meta-Analysis, PubMed
- In a study of 69 women aged 35 to 55, 8 weeks of collagen hydrolysate supplementation significantly improved skin elasticity compared with placebo. Oral Supplementation of Specific Collagen Peptides Has Beneficial Effects on Human Skin Physiology, PubMed
- A meta-analysis of 11 randomised controlled trials (870 participants) found collagen supplementation significantly improved pain and function scores in people with knee osteoarthritis. Effect of Collagen Supplementation on Knee Osteoarthritis: An Updated Systematic Review and Meta-Analysis, Clinical and Experimental Rheumatology
Our take: Clinical research suggests oral hydrolysed collagen supplementation supports skin hydration and elasticity, and may also benefit joint function and comfort. This is why every dose of Her Eir delivers 5g of hydrolysed collagen, a level informed by the research above.
Vitamin C
What it does: Vitamin C is an essential cofactor for prolyl and lysyl hydroxylase, the enzymes required for collagen biosynthesis, and plays a role in stabilising the collagen triple helix.
What the evidence shows:
- A foundational review explains vitamin C's role as an essential cofactor in collagen biosynthesis. Regulation of Collagen Biosynthesis by Ascorbic Acid: A Review, PubMed
- Research published in the American Journal of Clinical Nutrition describes vitamin C as required for hydroxylation of proline in procollagen and stabilisation of the collagen triple helix, noting that deficiency is associated with defective connective tissue and impaired wound healing. Ascorbate Requirement for Hydroxylation and Secretion of Procollagen, American Journal of Clinical Nutrition
- A review in Nutrients discusses vitamin C's broader role in skin health, including collagen synthesis and antioxidant protection. The Roles of Vitamin C in Skin Health, PubMed
Our take: Vitamin C contributes to normal collagen formation. That's why it's formulated alongside our hydrolysed collagen, not as an afterthought, but as a necessary part of how your body actually puts collagen to use.
Protein
What it does: Each dose contains 10g of protein, supporting daily protein intake and muscle maintenance, which becomes increasingly important for women through midlife and the menopausal transition.
What the evidence shows:
- A systematic review of nutrition interventions in middle-aged and older women found that protein-based interventions can have beneficial effects on muscle-related outcomes. Nutrition Interventions on Muscle-Related Components of Sarcopenia in Females: A Systematic Review of Randomized Controlled Trials, Calcified Tissue International
- A systematic review and meta-analysis of whey protein supplementation in postmenopausal women found that, when combined with resistance training, it significantly improved measures including muscle strength and lower-limb lean mass. Effect of Whey Protein Supplementation in Postmenopausal Women: A Systematic Review and Meta-Analysis, PubMed
- A narrative review discusses the role of dietary protein and collagen-derived protein in connective-tissue remodelling, and why collagen is particularly rich in glycine and proline, amino acids abundant in connective tissue. The Impact of Collagen Protein Ingestion on Musculoskeletal Connective Tissue Remodeling, Nutrition Reviews
Our take: We include 10g of protein to support your daily protein intake and muscle health, so you're getting a genuine nutritional boost, not just a collagen top-up.
Bee Pollen
What it does: Bee pollen is a naturally nutrient and phytochemical rich ingredient, containing polyphenols, carotenoids, vitamins, minerals and other bioactive compounds.
What the evidence shows:
- Research points to potential antioxidant and anti-inflammatory properties, though human clinical evidence is less developed and less standardised than for collagen or vitamin C. Biological and Therapeutic Properties of Bee Pollen: A Review, PubMed
- A 2026 comprehensive review of bee products notes a range of potentially bioactive compounds, but highlights a lack of standardisation and the need for further clinical trials before broader conclusions can be drawn. Health Effects of Bee Products: A Comprehensive Review, PMC
Our take: We include bee pollen for its naturally rich nutrient and phytochemical profile, the kind of complete, whole-food addition that fits our belief in taking only what nature offers.
The formulation, at a glance
COLLAGEN Provides collagen-derived peptides and amino acids. Clinical research suggests hydrolysed collagen can support skin hydration and elasticity, with additional evidence for joint-related outcomes.
VITAMIN C Supports normal collagen formation. Vitamin C is an essential cofactor in the biochemical processes required to form stable collagen.
PROTEIN Supports muscle and tissue maintenance. Adequate dietary protein becomes increasingly important for maintaining muscle mass and function as women age.
BEE POLLEN A naturally nutrient and phytochemical rich ingredient. Bee pollen contains a diverse mixture of nutrients and plant-derived compounds, including polyphenols and carotenoids. Clinical evidence for specific health outcomes remains limited and variable, as composition differs between pollen sources.
This is why we formulated it this way
No guesswork, no filler, no ingredient added just because it sounds good on a label. Every gram in your Her Eir blend is there because the evidence supports it, at a dose that reflects the research, not marketing convenience. That's the standard we hold ourselves to, and it's why we can stand behind every dose.
