Why Men Need Collagen More Than Women – Thomas DeLauer
Hair, Skin & Nails
Study – Skin Research and Technology
Subjects comprised 173 men and women, divided into four groups according to age.
Photographs were taken from nine facial regions and used to classify the intensity of wrinkles into five grades
In all age groups, men showed increased forehead wrinkles compared with women
In contrast, no gender-dependent differences were found in upper eyelid wrinkles. Other facial wrinkles were greater in men than in women in all except the oldest group (age, 65-75 years), in which wrinkles in women were greater than or equal to those in men.
Results showed that gender-dependent differences exist in the degree of facial wrinkles – but, in general, men tend to have more severe wrinkles than women
This tendency disappeared or was reversed in some regions of the face and in individuals more than 60 years old
A study published in Experimental Physiology found that with strength training women’s muscle fibers are converted to type I fibers, whereas in men they generally change to type IIa fibers
Type I muscle fibers are more efficient over long periods of time – mainly used for postural maintenance (such as holding the head upright), or endurance exercises (like marathon running).
Type II muscle fibers use anaerobic respiration and are better for short bursts of speed
The result is that women are more resistant to fatigue than men, even when women and men with the same strength level are compared
Between 1–10% of muscle tissue is composed of collagen, and, as such, it is necessary to keep your muscles strong and functioning properly
Study – British Journal of Nutrition
In one study, 27 frail men took 15 grams of collagen while participating in an exercise program daily for 12 weeks.
Compared to men who exercised but did not take collagen, they gained significantly more muscle mass and strength
Aside from collagen comprising muscle tissue, researchers also concluded that collagen may have improved strength gains due to its positive effect on creatine production
Collagen contains relatively high amounts of arginine and glycine, both known to be important substrates for the synthesis of creatine in the human body
Study – Proceedings of the National Academy of Sciences (PNAS)
The study found that women’s brains appear to be about three years younger than men of the same chronological age
Found that brain ages are an average of 3.8 years younger than the women’s chronological ages – men’s brains were 2.4 years older than their true ages.
Collagen & Joints
Collagen helps maintain the integrity of your cartilage, which is the rubber-like tissue that protects your joints
With joint pain/arthritis, inflammation stimulates the depletion of proteoglycans and damage to the collagen network and decreases the synthesis of cartilage matrix proteins – decreases cartilage
Theorized that supplemental collagen may accumulate in cartilage and stimulate your tissues to make collagen
Collagen hydrolysate ingestion stimulates a statistically significant increase in synthesis of extracellular matrix macromolecules by chondrocytes
Suggests this may lead to lower inflammation, better support of your joints and reduced pain
