FIT Lean Food Collagen features bovine collagen peptides complemented with beta-hydroxy-beta-methylbutyrate (HMB) and vitamin D3, making it an optimal choice for supporting collagen production, the integrity of connective tissues, and muscle health. A natural metabolite of leucine, HMB increases lean muscle mass through dual mechanisms: inhibiting protein degradation and promoting protein synthesis. This versatile formula rapidly disperses in water and is ideal for athletes or for individuals who need an easily digested protein source.
Collagen Peptides
Collagen is a primary structural component of connective tissue that
accounts for as much as 30% of the body’s total protein.[1] It is found in
skin, ligaments, tendons, cartilage, tooth dentin, bone, and muscle, and it
is also part of the structure of arteries and veins. Collagen protein has a
unique amino acid composition with an unusually high content of glycine
and proline along with the modified amino acid hydroxyproline, making it
ideal for supporting the turnover and renewal of structural proteins.*[2]
Due to the well-established function of collagen’s contribution to the
integrity of articular cartilage, supplemental collagen peptides have been
studied for their potential benefit to cartilage health. The results of a
randomized, double-blind, placebo-controlled study of subjects
(N = 30) with osteoarthritis (OA) who were given placebo or 5 g of
collagen peptide twice daily for 13 weeks demonstrated that collagen
peptides were effective in improving OA symptoms. The researchers
hypothesized that the mechanism for this effect is attributed to the role
that collagen peptides play in regulating chondrocyte differentiation and
stimulating proteoglycan synthesis, resulting in cartilage tissue support.*[2]
Several studies have explored the effects of collagen peptide
supplementation on body composition, strength, and muscle health
when combined with resistance exercise. In a randomized, double-blind,
placebo-controlled study of recreationally active male subjects (N = 57),
the test group was supplemented with 15 g of collagen peptides while
engaging in a resistance training program. Both groups showed a slight
increase in strength, but an increase in fat-free mass was observed in
the supplemented group, suggesting an increased effectiveness when
combined with physical activity. Muscle fiber biopsies in subjects did
not differ between the test or placebo group, leading the researchers to
attribute the increase of fat-free mass in the supplemented group with
hypertrophy of contractile muscle cells and possibly a higher increase in
connective tissue.*[1]
Many of the studies assessing the effect of collagen protein
supplementation combined with resistance training have been conducted
with male subjects. However, a 12-week randomized, controlled trial in
pre-menopausal subjects (N = 77) showed an increase in muscle strength
and fat-free mass in women who combined 15 g of collagen peptide
supplementation with resistance exercise three-times per week.*[3]
HMB
Beta-hydroxy-beta-methylbutyrate (HMB) is a metabolite of the essential
amino acid leucine found naturally within human muscle cells, and it has
been reported to have anabolic effects on protein muscle metabolism.[4,5]
Several mechanisms of action have been proposed to explain the action
of HMB on muscle health. Among them are that HMB attenuates training-
induced proteolysis via downregulation of proteolytic pathways, and it acts
as a signaling molecule for stimulation of protein synthesis.[5-7] Studies
conducted mostly in athletes have suggested that HMB supplementation
may exert beneficial effects on muscle mass and function, most notably
when combined with resistance-type exercise training.*[6,8]
In a randomized, double-blind, placebo-controlled, parallel design study,
subjects (N = 31) aged 70 and older were given 3 g of HMB or placebo
daily for eight weeks with a prescribed exercise program for five days
per week. In the supplemented group, subjects showed an increase in
lean body mass similar to that seen in younger adults, which reported a
decrease in muscle proteolysis and an increase in fat-free mass in young
adults with resistance training. The researchers suggested that the results
are indicative of the role HMB plays in decreasing proteolysis.*[9]
Results from a randomized study in young, healthy, sedentary subjects
(N = 37) given 3 g of supplemental HMB daily for three weeks showed an
increase in fat-free mass and total body strength suggesting that HMB
partially attenuates muscle protein breakdown without exercise.[10] To
further illustrate the benefit of HMB supplementation on muscle health
without any form of exercise, a randomized, double-blind, placebo-
controlled, parallel design study was conducted with healthy subjects
(N = 24) aged 60-76 years who were confined to complete bed rest.
Subjects in the test group were given 3 g of HMB five days prior to

Results suggested that HMB helped to preserve muscle mass during the
immobilization period.*[11]
Several systematic reviews and meta-analyses have helped to solidify the
body of evidence supporting the effectiveness of HMB on strength, body
composition, and muscle health in trained and untrained individuals. A
meta-analysis of randomized, placebo-controlled trials with supplemental
HMB in doses ranging from 1.5 to 6 g/day for a three- to nine-week period
indicated sufficient data to support strength gains in untrained participants
and a negligible effect in trained individuals but with an inconsequential
effect on body composition.[5] A meta-analysis exploring the potential benefit
of supplements on lean mass and strength with resistance training reviewed
over 250 different supplemental ingredients and found that only six had
adequate research for inclusion. Nine HMB studies qualified with analysis
demonstrating that a 3 g/day dose provided support for net gain in strength
and lean mass gains.[12] The results of a systematic review and meta-analysis
assessing the outcome of HMB supplementation in a clinical setting of
subjects (N = 2,137) with conditions characterized by loss in skeletal muscle
mass and weakness were in line with previous reviews of older adults and
athletes, suggesting that the effect of HMB increases skeletal muscle mass
and improves muscle strength.*[13]

Vitamin D
Vitamin D has a well-known function in bone health due to its role in the
regulation of calcium and phosphate homeostasis. It has also been linked to
skeletal muscle health and function.[14,15] Low serum levels of vitamin D are
correlated with muscle weakness and myopathy. In vitro studies have shown
that vitamin D is necessary for the mitochondrial function of providing energy
to skeletal muscle cells.*[16]
A cross-sectional study examining the relationship between vitamin D status
and strength in collegiate athletes (N = 103) showed that a decrease in
serum D was correlated with a decrease in indicators of muscle strength and
anaerobic power. The authors concluded that vitamin D should be considered
as a component of training to maximize performance in sports requiring
muscular strength.*[17]
A systematic review and meta-analysis of 17 randomized-controlled trials
assessing vitamin D supplementation and its role in muscle strength
suggested that in individuals with baseline vitamin D levels the outcome of
supplementation was not significant, but an increase in strength was shown
in those who were deficient.[14] Another study analyzed the role of vitamin D
in muscle function with data from 30 randomized trials involving over 5,600
participants indicating that supplementation has a positive impact on muscle
strength. The authors suggested that additional research is needed to define
optimal dose, duration, and mode of administration.*[15]
There have also been studies on the combined effect of vitamin D with HMB.
In a randomized, double-blind, placebo-controlled, 12-month trial in older
subjects (N = 117), HMB (3 g) and vitamin D (2,000 IU) were shown to be of
benefit to muscular function with or without resistance training.[18] Another
study looked at previous data of vitamin D status in older adults who used
HMB supplements. It was found that muscle mass increased regardless of
vitamin D status, but strength increases were observed only in individuals
with adequate vitamin D status, demonstrating a synergistic effect of HMB
and vitamin D on muscle function.*[19]
