Are Collagen Supplements Effective?

GettyImages-1195245457Collagen is the most plentiful protein in the body and the primary structural component of connective tissues found in your bones, cartilage, tendons, ligaments and skin, aiding in their elasticity and strength. Our bodies naturally produce collagen; however, its production declines as we age, especially when paired with poor diet, excess alcohol use, lack of exercise, excess sun exposure, or use of tobacco products. The degradation of collagen and collagen production can lead to wrinkles and an aged appearance, both of which are feared in our youthful appearance-obsessed society, leading to an increased consumer interest in collagen and collagen-containing products in recent years.

Collagen Supplements: How to Buy It and What It Might Be Able to Do 

Collagen supplements are available in a variety of forms, including powders, pills, and fortified foods. They are often sold as “hydrolyzed collagen” or “collagen peptides,” both forms of collagen that have already been broken down and are therefore more readily absorbed by the body. There is some evidence to suggest that collagen supplements can improve skin elasticity and hydration, promote wound healing, and improve joint mobility and pain, and are generally deemed safe with no reported adverse health effects. However, the evidence that is available to support these claims is often unclear (for example, the exact dosage to experience benefits) or funded by related industries or authors with ties to those industries who may benefit from positive research outcomes, presenting a potential conflict of interest. Additionally, as with all other dietary supplements, collagen supplements are not assessed by the Food and Drug Administration (FDA) prior to being marketed; therefore, their efficacy and safety is not guaranteed.

Should You Take a Collagen Supplement?

Currently, there is not enough evidence to provide clear recommendations to support or advise against the use of collagen supplements. However, when searching for any supplement, including collagen, look for those with USP or NSF certifications on the label, which indicate that the product has been tested by a third party for purity, potency, and safety. Additionally, you should always consult a health care professional, such as your physician, prior to starting any supplement.

How to Protect Your Natural Collagen

Finally, there are some ways to naturally protect your body’s natural collagen without taking supplements:

  • Wearing sunscreen every day: UV light from the sun breaks down collagen.
  • Eating a healthy diet, with plenty of fruits and vegetables: Fruits and vegetables are rich in antioxidant Vitamin C, which can help protect collagen from damage and breakdown.
  • Controlling stress: Some studies have shown that chronically high cortisol (stress hormone) levels are associated with decreased collagen production.
  • Quitting smoking and limiting smoke exposure: Smoking may decrease the rate of collagen synthesis in the body.
  • Getting enough sleep: The National Sleep Foundation recommends between 7 and 9 hours of sleep each night for most adults.

Training the Active Aging Adult (Part 1 of 4)

There comes a day when you wake up one morning and realize you’re not 25 any longer. Usually, this happens when you’re 50—or in other words, after 25 years of denial and of being totally oblivious to nature’s less-than-subtle warnings: hair loss and color change, skin texture and wrinkles, where did that body fat come from, when did that thing (?) become so heavy to lift, and those stairs weren’t that high last year. The mind feels young but the body fades in and out of pretend youth. The body is also willing until it gets tired or pain rises above the level of annoyance.

But there is hope: you can be cool without being young, but cool doesn’t make you stronger, quicker, more flexible, thinner, and the owner of painless joints.

What Motivates Senior Fitness?

GettyImages-178872337_webWhen you were younger, the goal of exercise was to look better naked. It seems reasonable, because younger people look better naked than old farts. Besides, older people have more pressing issues like serious joint pain, heart disease, diabetes, age-related weight gain, hormonal changes, and perhaps even the chilling shadow of cancer has visited them. No doubt that looking better and feeling better about yourself is really an important motivator to exercise, but they pale in comparison to these life-altering issues. Therefore, the motives for training of an aging active adult are more complex than a 25-year-old and must be recognized and honored when designing training programs.

Specific Health Concerns for Active Seniors

If you happen to be a fitness enthusiast over 50, these are things you need to be aware of.

  • Sarcopenia: An interesting word to say, but not so good to have, because it means a loss of muscle mass. Heavy-chain muscle fibers start dying out around age 30. Most professional athletes retire in their 30s because they have lost a step (in power and strength) and can no longer compete with younger athletes. Since most adults do not push their athletic genetic limits, they become aware of this loss of step in their 40s, or certainly by their 50s. This fiber loss is called sarcopenia. Unless there is some attempt to retain strength through formal strength training, this strength loss will continue at a ever-increasing and very noticeable rate. Common movement patterns—sit to stand, picking things up, pushing away and pulling back, pushing up and pulling down—will become increasingly more difficult as life quality decreases. Many people just give in to the process and call it “getting older.” It doesn’t have to be that way. Strength training can certainly slow it down.
  • Joint issues: Connective tissue seems to injure more easily and take longer to heal. Tendonitis becomes an all-too-common answer to the question, “How are you feeling?” Dynamic joint mobility training helps regain joint range of motion and lubricate joint surfaces with synovial fluid for cartilage health. Older athletes have to allow time in the program design for something the young take for granted.
  • Slow recovery: It takes longer for the body to repair and to make new tissue. This seems to be related to changes at the DNA and RNA levels as we age; and of course, changes in hormonal levels further compound the problem. Knowing this, nutrition and rest are key for proper recovery. The aging active adult has very little margin for error. Without proper nutrition and rest, progress will stall and the likelihood for injury will increase.
  • Balanced training: Cardio exercise is still important for overall health, but must be managed in such a way as to not interfere with the recovery for strength training, and not to add to the training volume to the point of over-training and adversely effecting the immune system. The body also does not respond well to being forced to adapt to opposing stimulus (cardio vs. strength). It gets confused as to what exactly it is being asked to do. How much cardio is very individual, but it is easy to err on the side of too much. Interval training may be an answer to those concerns by reducing the training time factor while still challenging the alactate, anaerobic, and aerobic substrates for improved conditioning.
  • Shared epiphany: There is a common experience at this age that there is a price to be paid for all of the fitness and health-related issues you chose to ignore when you were younger. Pain, discomfort, illness, and excess body fat are the reasons for your body’s “come to Jesus” meeting. Your body demands corrections, and your currency for payment is time and effort spent bringing the body back into balance. The aging active adult has been humbled enough by aging to be open to addressing these issues if the guidance they receive makes sense.

With the number of active aging adults increasing, both trainers and the older clients should understand the training needs and limitations of this age group in order to develop the best program designs that will effectively produce results and at the same time do no harm. So far, the fitness industry and fitness media have chosen to ignore the 800-pound gorilla by focusing on the 25- to 40-year-olds; but it is the aging active adults who have the greater need. They understand that the youth genie is not going back in the bottle, but that their life quality can be a whole lot better through proper training and nutrition.

In part 2 of this series, I talk more about the need for strength training at this age.

Injury Prevention: Foam Rolling

Foam rolling is the layman’s term for self-myofascial release. What you are doing is giving your muscles and fascia (the connective tissue that runs head to toe in the body) a good massage. If you have had a deep-tissue massage, however, you know it can be painful. This is the only time in the gym that I recommend no pain, no gain. Now, that may seem masochistic, but a little discomfort on the roller can make a world of difference in how you feel as you move after a session.

How Foam Rolling Works

The rollers come in different densities, with softer being gentler. But if you want to break down tight muscles and fascia, you need to need to suck it up and take the pain. Let me explain it this way: When your muscles get stressed, they will tighten up in spots to hold on so they don’t strain or tear. Those spots limit mobility, thus decreasing your ability to move with your max range of motion. When the muscles have been stressed too much, the force will go up or down the chain into the joints (knees, hips, shoulders, etc.). Many times pain is not a result of the joint being damaged; it is from the muscles not being able to do their job.GettyImages-1226237804_web

When you roll on the roller, all those tight spots are the muscles with a little ball, so to speak, of tight fibers. When you roll over those spots, they will release. Over time, with commitment to your rolling, you will feel those spots be less tender and pain will decrease. With a muscle at full strength, you can do more with it in terms of flexibility and strength.

The Basic Foam Roller Exercise

So how is this done? Ideally the body should be warm (although you will break a sweat hitting your sore spots, I can tell you from personal experience).GettyImages-1226237964_web

  1. Grab a roller to lie on. You do want to try and hit the entire body. Surprisingly, you will find other spots you did not realize were sore.
  2. Move your body over the roller, avoiding bones and joints (those don’t respond to rolling).
  3. Make 5 to 10 passes over a muscle (or fascia) and then move to another part of the body.

You can do this after a workout as well to enhance recovery. You may notice you are less sore than when you started—aahh, the body’s way of working things out!GettyImages-1226237758_web

This is great for the day-after muscle soreness you get from a great (or new) workout.
