“To stay healthy and feel young”.

*Wellnex is a term coined by combining the word “wellness” and the symbol “x” and represents multiple possibilities.


The human body is made up of protein, fat and carbohydrate. Collagen is a type of protein largely found in the skin, and that accounts for the
30% of the total protein content in the body.

Collagen* constitutes 90% of the total protein found in the bones.
Bone descriptions have compare calcium to concrete while collagen has been referred to as the steel frame.

Loss of collagen leads to degeneration of cartilage, wrinkled skin and brittle bones etc.
*Collagen refers to type 1 collagen.


– Collagen is a cellular scaffold and also acts as a lubricant that facilitates intercellular exchange of diverse
substances owing to its ability to fill intercellular spaces.
– Ageing is associated with collagen degradation and loss, a process that can lead to cellular death.
– However, recent studies indicate that cells can produce collagen following stimulation with collagen-derived active ingredients.*

Participating subjects included 74 humans between 15 and 93 years of age. Both of these values begin to decrease sharply around the age of 20 years.

Levels of collagen Hyp peptides in the blood following oral ingestion


Supple skin | Improved viscoelasticity | Reduced wrinkles

o Rebuilds cartilage
o Prevents cartilage degeneration
o Improves bone mineral density

o Strengthens tendons and ligaments
o Reduces pain related osteoarthritis


Decrease in the number of hidden blemishes

Clinical Trial
o Randomized, Placebo controlled, double blind
o 39 female subjects aged 35 to 55 years with skin problems
    o Wellnex: 26 subjects
    o Placebo: 13 subjects

o Wellnex = 31 subjects,
   comparator – 34 subjects
o Evaluation: Dexa bone scan | Serum
   BAP | Serum OsteoCalcin

o Randomized clinical trial.
o Test materials: AAA Ca, 300mg, Collagen Peptide 3500mg, Composite
   Mucopolysaccharide 200mg, Glucosamine 600mg, Vitamin C 200mg, Glucose,
   Maltose, citric acid, lemon juice, lemon flavour and acesulfan.

o Supplementation group: Ca-Collagen-Matrix, dissolved in warm water, 3 times/day,
   after meal for 4 months + basal treatments before and after study period.
o Control group: Only Basal treatment.

o Measurement: Pain was assessed subjectively by the face scale and objectively by
   measuring skin impedance.
o Skin impedance measured in quiet sitting position and after applying loads to the
   spine and knee joints.

o Marked alleviation of subjective pain in supplementation group.
o A fall of skin impedance was also alleviated in supplementation group.
o Basal skin impedance was significantly reduced (usually increase with age)
   in supplementation group.
