What Are Collagen Supplements?
Collagen supplements typically contain types 1, 2, and 3 collagen from bovine, fish, or other marine sources. Collagen peptides come in powder or liquid form for easy consumption.
The most common types of collagen supplements include:
- Collagen peptides - Hydrolyzed collagen (broken down into peptide fragments)
- Gelatin - Collagen that has undergone partial hydrolysis
- Liquid collagen - Collagen peptides dissolved in a flavored liquid
Collagen supplements are free of fat, carbohydrates and gluten. Unflavored versions are generally tasteless and can be added to coffee, smoothies or food. They mix best in cold liquids.
Possible Benefits of Collagen Supplements
Here are some of the key benefits that research has uncovered about supplemental collagen:
May Improve Skin Elasticity and Hydration
Several studies have found that taking collagen supplements regularly can significantly improve skin elasticity, hydration and overall appearance. Women experienced less facial wrinkling and dryness after taking collagen in both the short-term and long-term.
Could Reduce Joint Pain
The collagen in cartilage provides flexibility and resilience to joints. Studies suggest supplemental collagen may reduce inflammation and stimulate collagen synthesis within joints. This was found to reduce pain and discomfort associated with osteoarthritis.
May Support Bone Health
Collagen makes up about 30% of the protein in bone tissue. Some evidence suggests collagen peptides may improve bone mineral density and prevent bone loss in postmenopausal women when taken for at least 6 months.
Could Promote Heart Health
Collagen provides structure to blood vessels and arteries. Taking collagen supplements may help reduce stiffness in arteries, improve blood vessel function and normalize cholesterol levels - all key factors for heart health.
May Aid Gut Health and Digestion
Gelatin has been used traditionally to soothe GI issues by coating and protecting the intestinal tract. Studies show supplemental collagen may improve symptoms of leaky gut syndrome and inflammatory bowel diseases like ulcerative colitis.
Could Strengthen Hair and Nails
Collagen is a major structural protein in hair and nails. Though limited, some studies indicate daily collagen intake leads to faster nail growth and may reduce breakage. It may also improve moisture and shine for healthier-looking hair.
May Boost Muscle Mass
Emerging research suggests collagen supplements paired with resistance training may improve muscle mass and strength more than training alone. This may be due to collagen stimulating muscle protein synthesis.
Is There a Recommended Collagen Dosage?
Currently, there are no official recommendations for the best collagen dosage. However, most studies investigate benefits with dosages between 2-15 grams per day. The average seems to be around 10 grams or about 1-2 scoops.
It’s best to follow the usage instructions on the particular product you purchase. But anywhere from 5-15 grams daily seems to be both safe and effective for most adults.
When Should You Take Collagen?
Collagen supplements can be taken any time of day. Some evidence suggests taking it in the morning on an empty stomach may allow for better absorption. But realistically, it can be taken whenever is most convenient - morning, afternoon or evening.
Try adding collagen peptides to your smoothie, oatmeal or coffee to help start your day. Otherwise take it before or after a workout or mix it into a post-dinner tea or dessert.
How Long Does It Take to See Collagen Results?
Benefits from supplemental collagen don’t happen overnight. Consistency is key. Most studies showing positive results had participants take collagen for at least 4-8 weeks, with enhanced effects seen after 2-3 months.
Improvements seem to peak around the 6 month mark. So stick with your daily collagen regimen for at least several months before expecting to see significant changes in skin, hair, nails or joints.
Can You Take Too Much Collagen?
The risks of taking too much collagen are generally quite low. Collagen supplements are considered very safe, with few side effects reported.
Higher doses up to 30 grams per day have been tested without any adverse impacts. Exceeding the recommended dosage doesn’t appear to pose any serious health risks.
However, more is not necessarily better when it comes to collagen. Taking more than directed won’t enhance or speed up results. Your body can only absorb and use so much at one time.
Are There Any Side Effects?
The most commonly reported side effects of collagen supplements include:
- Upset stomach
- Nausea
- Heartburn
- Diarrhea
- Rash
- Bloating
- Fullness or heaviness
- Bad taste
Luckily these issues tend to be mild and generally clear up quickly after stopping supplementation. Starting with smaller doses and gradually increasing over time can help minimize digestive discomfort.
Those with food allergies should also exercise caution, as collagen supplements are animal-derived. Contamination and allergic reactions are possible, though unusual.
Who Should Not Take Collagen?
While considered very low risk, there are some instances where collagen supplementation may not be appropriate, including:
- Food allergies - Potentially risky due to animal sources
- Pregnancy and breastfeeding - Lack of safety research
- Surgery - May impact blood sugar
- Diabetes - May lower blood sugar levels
- Cancer - Effect on tumor growth unknown
- Kidney disease - Concerns with buildup of certain proteins
Those with these conditions or taking certain medications may want to consult their healthcare provider before using collagen supplements.
How to Choose a Good Collagen Product
With so many collagen products out there, it can be hard to decide which one is best. Here are some tips for picking a quality collagen supplement:
- Types 1 and 3 - Look for products with a combination of types 1 and 3 collagen for balanced benefits
- Hydrolyzed - Hydrolyzed collagen (collagen peptides) are better absorbed than unhydrolyzed
- Third-party testing - Choose brands that have been independently tested for purity and potency
- Minimal ingredients - Avoid added sugars, preservatives and artificial flavors
- Reputable company - Select well-known, trustworthy manufacturers and brands
- Sustainable sources - Marine collagen helps conserve environmental resources
Should You Try Collagen Supplements?
Collagen supplements appeal to those looking to counteract natural declines in collagen production. The protein’s unique benefits for skin, hair, nails, bones and joints make it stand out from other wellness supplements.
While research is still emerging, the proven safety profile of collagen and its wide-ranging effects make it worth considering. Just be sure to choose quality products and take it consistently for best results.
Maintaining sufficient collagen levels through strategic supplementation helps keep the body functioning optimally and supports that youthful glow. So yes, adding collagen to your routine is likely worthwhile - as long as you don’t overdo it! Stick within the safe recommended dosages to reap all the benefits without going overboard.
