The final phrase – Does Liquid Collagen Work?
?
Liquid collagen is the dietary complement du jour, because of an inventory of potential advantages that features healthier-looking pores and skin, more-flexible joints, stronger bones, and weight reduction. Is it doable that one complement can do all that? Possibly.
Collagen—the fibrous protein made by your physique, not essentially the complement—is type of superior, says Robin Foroutan, RDN, an integrative medication dietitian on the Morrison Middle in New York Metropolis and a spokesperson for the Academy of Vitamin and Dietetics.
“It’s the most abundant protein in our body and provides structure and lubrication,” she says. “We are made mostly of collagen, and by the ripe old age of 25, this nutrient just falls off of a cliff.”
Certain indicators that you just’re in collagen-loss free-fall are wrinkles and sagging pores and skin. Although you should still be consuming collagen-boosting meals (like meat, fish, soy, and quinoa), your physique can have bother utilizing the protein to make collagen. It is sensible that you just’d search for methods so as to add it again into your physique. That’s the place collagen dietary supplements are available in (and why their reputation is on the rise).
Collagen dietary supplements are primarily offered as powders, capsules, or liquids. Typically the protein is added to meals like bars or butter-like spreads. (Try this Important Proteins collagen creamer overview.) Selection of liquid, capsules, powder, or fortified meals is known as a matter of non-public choice, says Foroutan.
Liquid collagen–whether or not flavored or unflavored—is present in premade collagen drinks, collagen-infused waters, pictures, and bone broths. They’re excessive in protein and low in energy, claiming to construct up your collagen shops from the within out, Foroutan says. However do they really work?
Right here’s what it’s good to learn about liquid collagen, and whether or not it’s value your cash.
Forms of liquid collagen
There are three principal points of collagen to think about: its kind, its supply, and the way it’s damaged down.
There are 16 sorts of collagen within the human physique, however the 4 most typical sorts of collagen are Sorts I, II, III, and IV. The massive majority of liquid collagen dietary supplements available on the market comprise Sort I, says Tod Cooperman, MD, president of ConsumerLab, an unbiased supplement-testing group in White Plains, New York. This kind is present in your pores and skin, tendons, ligaments, and bones.
Though vegan collagen powder has been cropping up extra today, most liquid collagen dietary supplements are extracted from animal sources, similar to hides, bones, or fish scales. (Right here’s what it’s good to learn about marine collagen.)
You might also discover some technical phrases in your collagen complement labels—issues like “hydrolyzed” and “undenatured.” These relate to how the collagen is damaged down, which impacts absorption. They embrace:
Hydrolyzed: Most collagen liquids available on the market are hydrolyzed, which implies the collagen has been damaged down into fundamental amino acids that function constructing blocks of proteins, says Foroutan. This provides you the uncooked supplies your physique must construct its personal collagen.

Gelatin: That is additionally damaged down from massive proteins however much less so than hydrolyzed collagen.

Liquid collagen advantages
Liquid collagen could assist enhance pores and skin well being and elasticity, lubricate joints, strengthen bones, and spur weight reduction, however extra analysis is required to again up and bolster all of those claims, Foroutan says. Listed here are a number of the touted advantages of this type of collagen.
Could increase pores and skin well being
Sipping a collagen complement would possibly assist your pores and skin, based on a research printed in 2019 in Vitamins. Within the research of 72 wholesome ladies age 35 or older, half drank Elasten, a liquid collagen that comprises 2.5 grams of collagen peptides plus vitamin C, zinc, biotin, and a vitamin E advanced, and half consumed a placebo. On the finish of the 12-week research, pores and skin rankings prompt that the drink improved pores and skin hydration, elasticity, roughness, and density in contrast with the placebo. Larger pores and skin density is an indication of more healthy and extra considerable collagen. However large disclaimer: this analysis was funded by the producer of Elasten.
In a 2018 Vitamin Analysis research, individuals who drank a liquid collagen complement for 90 days reported an enchancment of their pores and skin texture and elasticity. (This research was additionally carried out by the producer.) The complement contained different elements, together with nutritional vitamins, antioxidants, minerals, chondroitin sulphate, and glucosamine.
Along with being industry-funded, a draw back to each of these research is the truth that contributors didn’t take collagen alone. With out finding out liquid collagen by itself, we are able to’t know whether or not the skin-health advantages occurred because of the collagen, one (or all) of the opposite vitamins, or a mix.
But the analysis holds promise.
“Based on the limited number of studies available, preliminary results are promising for the short-term and long-term use of oral collagen supplements,” says Adam Friedman, MD, professor and chair of dermatology at George Washington College of Drugs and Well being Sciences in Washington, D.C. “They have shown some potential to increase skin elasticity, hydration, and dermal collagen density, though selecting which one is certainly difficult.”
Foroutan suggests selecting a collagen complement with added vitamin C, which is believed to assist your physique take up collagen.
Could cut back joint ache
The Vitamin Analysis research additionally discovered that contributors who drank the collagen complement reported a 43 p.c discount in joint ache and a 39 p.c enchancment in joint mobility. Presently, osteoarthritis, the wear-and-tear type of the illness, is handled with over-the-counter or prescription painkillers, which all have their justifiable share of unwanted side effects.
Collagen dietary supplements, nonetheless, seem like protected, with a really low threat of unwanted side effects, says Mark Moyad, MD, the Jenkins/Pokempner director of preventive and various medication on the College of Michigan Medical Middle in Ann Arbor. If something, you would possibly expertise some abdomen signs, a headache, dizziness, or a rash from collagen liquids.
In contrast, overuse of the over-the-counter painkiller acetaminophen could cause liver injury. And using nonsteroidal anti-inflammatory medicine (NSAIDs) similar to ibuprofen and naproxen has been linked to bleeding ulcers. All issues thought of, liquid collagen could also be value a attempt to see if it makes a distinction in your joint ache and performance, Dr. Moyad says.
Could improve bone energy
Throughout menopause, manufacturing of the feminine intercourse hormone estrogen drops, and in consequence, the danger for the brittle bone illness osteoporosis goes up. In a 2020 problem of the Journal of Musculoskeletal and Neuronal Interactions, researchers gave collagen powder together with calcium and vitamin D to a gaggle of postmenopausal ladies with weakened bones. They discovered the complement would possibly assist construct and strengthen bones after three months of use. Observe, nonetheless, that the research was funded by a collagen producer.
The identical advantages might additionally happen with liquid collagen, Foroutan notes.
Could promote emotions of fullness
Can collagen actually show you how to drop some weight? Liquid collagen may be very excessive in protein, which might make you are feeling fuller longer, probably limiting how a lot you eat. This might result in weight reduction, says Moyad. Consuming a bowl bone broth between meals may be one technique to curb your urge for food.
When selecting liquid collagen, it’s essential to check energy, protein, and sugars per serving. With powdered collagen, you possibly can simply add water. Liquids, alternatively, could have extra energy as a consequence of different added elements, Dr. Moyad says.
Collagen liquid vs. serum
There’s the liquid collagen that goes in your mouth, and there’s the liquid collagen that goes in your pores and skin. What’s the distinction? Not like the collagen liquid you eat or drink, collagen serums declare to stimulate the manufacturing of this structural protein from the surface in.
“Applying collagen serums can moisturize and plump the skin, but that does not mean they can actually stimulate the body’s own synthesis of collagen,” says Deanne Mraz Robinson, MD, an assistant medical professor of dermatology at Yale New Haven Hospital. “Collagen molecules are too large to penetrate the skin, so look for peptides which are formulated to penetrate more effectively.”
For topical merchandise that stimulate your physique’s personal collagen creation, look to retinols, retinoids, or the plant-based various bakuchiol, she says. (That is the retinoid rule that dermatologists need everybody to comply with.)
Potential dangers of liquid collagen
They could not have many doubtless unwanted side effects, however liquid collagen merchandise are nonetheless dietary supplements. And people include a caveat. Dietary supplements aren’t regulated with the identical scrutiny as pharmaceutical merchandise, so it’s key that you just select a product from a good model that stands behind its complement, Dr. Friedman says.
ConsumerLab examined collagen merchandise to see in the event that they actually had the quantity of collagen promised on the labels. Excellent news: merchandise contained collagen within the quantities said on their labels, starting from a few 3-gram to 25-gram serving per day amongst powders and liquids.
Many collagen dietary supplements are produced from animal carcasses, so poisonous heavy metals could also be current, says Foroutan. In actual fact, a research of 28 best-selling collagen peptide dietary supplements on Amazon by the Natural Customers Affiliation discovered that:
64 p.c examined constructive for measurable ranges of arsenic
37 p.c examined constructive for measurable ranges of lead
34 p.c examined constructive for hint ranges of mercury
Don’t panic. “Minimal to low exposure is always expected,” Dr. Moyad says. “It is exposure above these levels, especially for long periods of time, that could increase the risk of health problems.” (Listed here are the secrets and techniques that vitamin producers don’t need you to know.)
One of the simplest ways to chop down your threat is to be selective relating to the producer. “When looking at a collagen supplement product, look for quality assurance reports. Or even ask the company for them,” Dr. Friedman says. “This can give insight in terms of purity and stability testing.” A 3rd-party seal of approval from ConsumerLab, NSF Worldwide, or U.S. Pharmacopeia (USP) can be a vote of confidence.
The final phrase
Liquid collagen dietary supplements could have some deserves, however extra analysis is required earlier than specialists say for positive they fulfill all of their guarantees. “If the claims sounds too good to be true, they likely are, and the marketing jargon is likely overcompensating,” Dr. Friedman says.
Not all merchandise are created equal. Be sure to decide on a good and clear model, and test the label to see if a product comprises different elements that might probably contribute to or sabotage your objectives. At all times comply with the dosing directions on the product’s label, and let your physician learn about any dietary supplements that you’re presently taking.
