Clinically Proven

To provide the highest quality possible, we produce our Collagen exclusively from fish scales, presenting unmatched advantages. Studies show that hydrolyzed collagen derived from fish scales consists of small peptide molecules that have superior bio-availability and digestibility when compared with other collagen products. Due to their lower molecular weight, these peptides are absorbed at a higher level through the intestinal barrier into the bloodstream, where they are then carried through the body, leading to collagen synthesis in the joint tissues, bones and skin dermis.

withinUs TruMarine™ Collagen is characterized by its unique amino acid composition, having high concentrations of glycine, proline and hydroxyproline. The interaction and concentration of these three specific amino acids have nutri-functional properties that support health and beauty by stimulating cells throughout the body. Studies show that the amount of Pro-Hyp peptides absorbed into the bloodstream is significantly higher after ingestion of fish scale collagen than other forms of collagen.

Effects of collagen peptide ingestion

Methodology: Placebo-controlled, independant, double-blind study on healthy women aged 40 - 54 years, who ingest either a placebo drink or a drink containing 5g or 10g of TruMarine™ Collagen peptide daily for 7 weeks.

Observations: Participants were examined by a licensed dermatologist at 3 weeks and 7 weeks. Wrinkles, pores, age spots and texture were objectively measured.*

The Results:
IMPROVED SKIN CONDITION

Unmatched advantages over pills or capsules: 1-2 scoops (5-10 grams) of Ultra-Pure withinUs TruMarine™ Collagen equates to approximately 10-20 capsules a day.

Skin Health

withinUs TruMarine™ Collagen is a bioactive ingredient that improves skin properties to achieve an optimal skin condition. Our product slows down the aging process by providing the body with the nutritional building blocks it needs. In particular, collagen contains much larger amounts of the amino acids glycine, proline and hydroxyproline than other proteins. These amino acids are necessary for promoting healthy tissue growth by the cells themselves. TruMarine™ Collagen is also highly digestible and is characterized by an improved bio-availability for optimal results.

withinUs TruMarine™ Collagen embraces the benefits of “beauty from within.” Comprehensive clinical studies have been carried out that highlight the numerous positive effects of ingesting TruMarine™ Collagen, including:

  • Increase in the water-absorbing capacity of the stratum corneum (the outermost layer of the epidermis)
  • Observed improvements to the skin
  • Reduction of UVB-induced skin damage
  • 10% difference in skin texture

Daily intake of TruMarine™ Collagen peptide helps to reduce wrinkles
In a double-blind clinical trial 88 women aged 35-65 years were given 5g of TruMarine fish collagen or dextrin (placebo) once daily for 8 weeks, with 43 and 45 subjects included in each group. Before treatment and at 4 and 8 weeks of treatment, digital images of the face skin were analyzed by VISIA® Complexion Analysis (Canfield, USA) with multiple end points for facial skin parameters related to cutaneous aging. A daily diary and a subjective self-assessment questionnaire of facial skin condition were asked at 0, 4 and 8 weeks at the conclusion of the study. This test was performed by SOUKEN after approval of Ethical Review. 

The number of wrinkles decreased by 8% after ingesting of marine collagen peptide for 8 weeks, corresponding to a 4-year-younger appearance.

Decreases age spots, improves overall look of facial skin, & creates a brighter appearance
In the placebo group, the number of age spots tended to increase (+3%). In contrast, in the collagen group, the number of age spots (brown and red skin lesions inclusive of hyperpigmentation, melasma, acne spots, vascular lesions and lentigines) had significantly decreased at 4 weeks as compared to before treatment (0 weeks).

Reduces pore size by 7%
In the collagen group, the number of pores had significantly decreased at 8 weeks compared with 0 weeks. In contrast, no significant change was detected in the placebo group.

Improves skin texture by 10%
The VISIA Texture Analysis measures skin color and smoothness by identifying gradation in color from surrounding skin tone, as well as peaks and valleys on the skin surface. A variation in skin surface texture results in uneven appearance.

In the collagen group, the number of texture variations had significantly decreased at 4 weeks and 8 weeks compared with 0 weeks.

Daily ingestion of TruMarine Collagen peptide significantly improves the overall look of facial skin, resulting in a more even appearance (-10%) at both 4 and 8 weeks.

70-80% of women are able to observe the effects of collagen peptide ingestion on the skin
Placebo-controlled, double-blind study on healthy women aged 40-54, ingesting either a placebo drink (50 ml) or a drink containing 5g or 10g of collagen peptide daily after dinner for 7 weeks (1). 

At 3 weeks, only 10% of the placebo group answered “better,” while this value was 41% in the 5g per day group and 62% in the 10g per day group.

Improves skin function + increases water absorption
In a double blind test young female volunteers consumed a drink containing 10g of collagen or placebo every day for 2 months.

The chart below shows the increase in water absorbing capacity of the stratum corneum of the skin during the test period. The increase in water absorbing capacity of the collagen-ingesting group (80.2μS) was larger than that of the placebo group (10.8μS) at 1 month, and the difference became larger between the collagen group (203.5μS) and the placebo group (113.7μS) when the test period was extended to 2 months. The increase in the placebo group may be explained by the fact that both the placebo drink and the collagen drink contained vitamin C, which may have improved skin function.

Bone Health

withinUs TruMarine™ Collagen peptides help maintain bone health and restore bone mineral density in order to reduce the risk of osteoporosis. Individuals of all ages can benefit from taking collagen to preserve bone condition and improve quality of life.

withinUs TruMarine™ Collagen provides multiple benefits, enhancing bone health by:

  • Improving bone mineral density
  • Reducing bone resorption and stimulating bone formation
  • Increasing bone strength and reducing the risk of fracture

Clinical Trials + Results

TruMarine Collagen™ is superior to Casein in its potential to enhance bone mineral density during protein undernutrition
When given food containing 10% casein, bone mineral density was found to be significantly lower compared to those given food containing 14%. The chart below shows bone mineral density raised for 10 weeks with food containing 6% casein, 10% casein or 6% casein + 4% collagen. The horizontal axis shows the position in the femur, while the vertical axis indicates the bone mineral density at that position. Bone mineral density in those given food containing 6% casein + 4% collagen was significantly higher when compared to those given 10% casein.

Joint Health

Collagen is a bioactive ingredient that promotes joint health by helping to repair joint matrix degeneration and improve long-term joint comfort and mobility. Comprehensive clinical studies have shown that ingesting collagen:

  • Improves joint health by strengthening cartilage and joint structure
  • Helps to repair joint matrix degeneration
  • Enhances joint comfort and mobility to reduce joint pain

Clinical Trials + Results

Ingestion of Collagen Peptides improves joint mobility and comfort
24-week prospective, randomized, placebo-controlled, double-blind test study on the use of marine collagen hydrolysate as a dietary supplement. Athletes with activity-related joint pain were administered collagen peptide (10g per day) or placebo. Joint pain at rest and while walking was considerably improved.
