The formula
Why collagen needs a Lemon
Collagen needs vitamin C to become collagen
Collagen cannot be assembled without vitamin C — the enzymes that build it simply stop working without any. So a full day's worth goes into every sachet rather than being left for you to find somewhere else.
Key ingredients and why they matter
Vitamin C100% Daily Value
Collagen can't become collagen without it — so we put a full day's worth in every sachet, and you never have to think about it. That's your vitamin C sorted before breakfast, too.
Organic LemonsReal squeezed juice
Real squeezed lemons. They're why every glass tastes like a holiday — and a ritual you look forward to is one you actually keep.
Wild-Caught Marine Collagen5g · hydrolysed
The reason you're here. Five grams of wild-caught marine collagen, hydrolysed into small peptides your body can absorb and put straight to work — skin that keeps its bounce, nails that break less, joints that feel easier.
Organic Monk FruitNo sugar, no spike
Sweetness without the sugar. Monk fruit keeps a glass at thirty-five calories and doesn't spike your blood sugar — a treat you can have every single day without a second thought.
Research behind this panel
- Vitamin C is required for collagen synthesis. Established by the cure of scurvy — the disease of collagen failure — and by the enzymology: prolyl- and lysyl-hydroxylase are ascorbate-dependent. As little as 6.5 mg a day prevents scurvy (Sheffield trial, 1953); each sachet carries 90 mg. EU-authorised claim: “Vitamin C contributes to normal collagen formation for the normal function of skin.”
- Hydrolysis and absorption. Skov et al., Nutrients 2019 — randomised blinded crossover, n=10: enzymatically hydrolysed collagen raised plasma hydroxyproline AUC by 33% and the combined glycine–proline–hydroxyproline pool by 19% versus the same collagen unhydrolysed. PMID 31086034.
- Monk fruit and blood sugar. Smeets et al., Am J Clin Nutr 2026 — randomised crossover, n=30: a monk-fruit-sweetened drink left glucose and insulin unchanged from water; sucrose raised insulin 7.8–9.3× at 15 minutes. PMID 42323164.
- Eriocitrin. Lemon’s principal flavanone. In a randomised crossover (n=16) it was absorbed to a higher peak and total exposure than orange’s hesperidin. PMID 33799874.
Findings are for the ingredients generally, not this product specifically.
The reason
Why does collagen need topping up?
Because your body makes less of it as you go. Skin collagen falls steadily through adult life in women and men alike — and after menopause the decline speeds up sharply.
From your twenties
Steadily less
Skin collagen declines with age in both sexes.
After menopause
−2% a year
For up to fifteen years.
The first five years
up to −30%
The steepest stretch.
Your body never stops needing collagen. It just stops making as much of it — which is where a daily 5g comes in.
Research behind this panel
- Decline through adult life. Shuster, Black & McVitie, Br J Dermatol 1975 (PMID 1220811): forearm skin collagen measured across a large normal population — decreased with age, and lower in women at all ages.
- After menopause. Skin collagen declines with menopausal age at an average 2.1% per postmenopausal year over 15 years in women not on HRT — Brincat et al., BJOG 1985 (PMID 3978054) and Obstet Gynecol 1987 (PMID 3601260); reviewed in J Cosmet Dermatol 2025 (PMID 40847905) and Clin Cosmet Investig Dermatol 2022 (PMID 36017417).
- The first five years. Type I and III skin collagen thought to fall by as much as 30% in the first five years after menopause — Thornton, Dermato-Endocrinology 2013 (PMC3772914).
The curve shows the shape of the decline, not measured values; the figures on it are the measured rates. Rates are for skin collagen after menopause in women not taking HRT, and the decline is not linear. No established annual rate exists for men or for women before menopause.

Research behind these benefits
- Skin. Meta-analysis of 26 randomised placebo-controlled trials, 1,721 people (Nutrients 2023, PMID 37432180): hydration and elasticity both improved, fish collagen the strongest source for hydration, effects larger after 8+ weeks. Eye-wrinkle volume −20% and skin procollagen +65% at 2.5g/day over 8 weeks in 114 women (Proksch 2014, PMID 24401291).
- Joints. 5g/day for 12 weeks in 180 physically active adults reduced activity-related knee pain vs placebo (Zdzieblik 2021, PMID 33562729); 10g/day for 24 weeks in 147 athletes (Clark 2008, PMID 18416885). Meta-analyses in knee osteoarthritis show reduced stiffness and better function (PMID 30368550, 39212129). One independent 12-week trial found no benefit (Bongers 2020, PMID 31990581).
- Bone. 5g/day for 12 months in 131 postmenopausal women, double-blind: spine BMD +3.0% vs −1.3%, femoral neck +6.7% vs −1.0% (König 2018, PMID 29337906).
- Nails. 2.5g/day for 24 weeks: growth rate +12%, broken nails −42% (Hexsel 2017, PMID 28786550). Open-label, not placebo-controlled.
- Muscle. Meta-analysis of 19 trials, 768 people: fat-free mass SMD 0.48 with resistance training, GRADE moderate (Bischof 2024, PMID 39060741). Doses were 15g/day.
- Sleep. 15g collagen peptides before bed for 7 nights: fewer awakenings on polysomnography (21 vs 29), sleep onset and efficiency unchanged (Thomas 2024, PMID 37874350). Glycine 3g before bed: shorter sleep latency, better subjective quality (Yamadera 2007; Bannai 2012, PMID 22529837). A 5g sachet supplies about 1.1g glycine.
- Energy and mood. 10g/day for 8 weeks in 66 adults who tire easily, double-blind: POMS fatigue-inertia lower and vigour higher vs placebo (PMID 39291817).
- Hair. 1g/day fish collagen peptides for 24 weeks, placebo-controlled, n=114: hair diameter increased (Hwang 2026, PMID 41788055).
All findings are for collagen peptides generally, not this product specifically. Doses and durations vary by study and are given above.
On a GLP-1
Why collagen on a GLP-1?
Rapid weight loss often depletes skin collagen and lean body mass along with the fat. Supplementing collagen helps rebuild both — more so if you're lifting. Ours tastes like a clear, light lemonade: perfect for days when you're already full.
What the weight loss takesThe cost
20%collagen loss
The skin pays for it
Year and a half of rapid weight loss can deplete up to 20% of skin collagen. That's the amount that a mature skin naturally ages by over a full decade.*
25%lean mass loss
Muscle leaves with the fat
A quarter of the weight lost isn't fat. It's muscle and the scaffolding that holds skin taut — and it only rebuilds from protein.
What you might get back in just weeksThe answer
9%collagen · 12 weeks
Measured, not felt
Supplemented marine collagen peptides raised collagen in the skin by about 9% — enough to show up on a scan. In twelve weeks.
7.4%lean mass · 12 weeks
If you're lifting, it counts double
Strength training grew lean mass 7.4% with collagen peptides — against 5.3% on training alone. In twelve weeks.
Footnotes and research
* Post-menopausal decline. Skin collagen falls about 2.1% per postmenopausal year, for up to 15 years. It tracks menopausal age rather than chronological age — so "a full decade" means a woman's decade after menopause, not any ten years of life.

The timeline
How long until I see a difference?
The first changes are ones you feel rather than see — skin holding water, nails bending instead of splitting — and they tend to turn up around week four. The visible ones take eight to twelve weeks of drinking it daily.
The foundation phase
- Subtle shifts in skin hydration and nail strength
Visible wellness &
beauty boost
- Firmer skin and stronger nails
- Greater joint comfort, more energy and vitality
Transformation & lasting results
- Smoother, radiant skin with fewer visible fine lines
- Thicker hair strands and stronger, less brittle nails
- Consistent joint ease
Why this one
Why does a clean label matter?
A clean label is more than a trend. A supplement cannot do much for you if it arrives with a long list of things you would rather not swallow.

|---|---|---|---|
| Preservatives | None | Usually potassium sorbate; some add sodium benzoate | Why it mattersHigher intake of preservatives like sorbates and sulfites is linked with 16% more cancer and 29% more high blood pressure. |
| Sweetener | Organic monk fruit | Mostly stevia; some sucralose or erythritol | Why it mattersSucralose and saccharin impaired glucose responses within two weeks in a controlled trial. In a separate study, a monk-fruit drink didn’t raise blood sugar or insulin. |
| Ingredient list | Five, all readable | Typically 8 to 13 | Why it mattersEvery ingredient is one you can recognize: organic lemon juice, marine collagen, organic flavors and extracts, organic monk fruit and vitamin C. |

“Typical” is based on the published ingredient lists of 16 liquid collagen sachets and shots, reviewed October 2026; it describes the category, not any one brand. Cohort studies show association, not cause. None of these studies tested the Liquid Collagen Elixir; they are about the ingredients we chose to leave out.
The ritual
How do I use it?
Tear the top off a sachet — it is flexible packaging, so no scissors and no shaker.
Pour it into 12–16 oz of cold water and stir. It dissolves straight away; ice and a wheel of lemon do it no harm at all.
Drink it whenever suits you. There is no best time — the thing that matters is that it happens most days.
Feeling creative? Sparkling collagen lemonade, honey-lemon glow shots, a lavender spritz — the recipes are on the blog.
Daily servingWe recommend one or two sachets a day.

Reviews
Collagen is the most abundant protein in the body and the main structural protein of skin, tendons, ligaments and bone. Skin collagen declines gradually through adult life in both men and women, and after menopause it can fall by up to 30% in the first five years. The visible signs include fine lines and skin that feels less firm. A daily collagen supplement supplies the collagen peptides and amino acids your body builds collagen from.
The Liquid Collagen Elixir is a ready-to-mix marine collagen supplement: 5g of hydrolyzed marine collagen with organic lemon juice and 90mg of vitamin C in a single-serve sachet.
How to use: mix 1–2 sachets into 16oz of cold water daily — it dissolves instantly and tastes like fresh lemonade. Take it daily for 8–12 weeks for best results.
Our marine collagen comes exclusively from wild-caught cod, haddock, and pollock from the North Atlantic — never farmed fish, so no antibiotics or added hormones. The other ingredients — organic lemon juice, organic monk fruit, and organic flavors and extracts — are certified organic, and the finished formula is Non-GMO Project Verified.
Vitamin C. Your body cannot make collagen without it, and each sachet pairs its 5g of marine collagen with 90mg of vitamin C — 100% of the Daily Value — in one drink. It's made with organic lemon juice, so it tastes like fresh lemonade rather than a supplement.
Many women add collagen to their skin, hair and nail routine, and skin collagen falls fastest in the years after menopause. We designed the Liquid Collagen Elixir for busy days: one sachet of 5g marine collagen and 90mg vitamin C, mixed into cold water at the office, before the gym or at home. It tastes like fresh lemonade.
Your body can't make collagen without vitamin C — the enzymes that build collagen depend on it. Vitamin C contributes to normal collagen formation for the normal function of skin, and to the protection of cells from oxidative stress. Each sachet provides 90mg, 100% of the Daily Value, alongside 5g of marine collagen.
Marine collagen is predominantly Type I, the main collagen in skin. In a 2023 analysis of 26 clinical trials, collagen supplements improved skin hydration and elasticity, and collagen from fish showed the strongest effect on hydration, with larger results after 8 weeks or more. For hair, the research is earlier: in small placebo-controlled trials, people taking 2.5–5g of collagen peptides a day had slightly thicker hair strands after 8–16 weeks. Each sachet pairs 5g of marine collagen with 90mg of vitamin C, which your body needs to make collagen.
Hydrolyzed collagen is collagen broken down into small peptides — think spaghetti snipped into rice grains — the form the body absorbs best. Ours is wild-caught North Atlantic marine collagen from cod, haddock and pollock, and it's predominantly Type I, the type found most in skin.
For skin, marine collagen has the edge in the research so far. It's predominantly Type I, the main collagen in skin, and in a 2023 analysis of 26 clinical trials, collagen from fish showed the strongest effect on skin hydration. Ours comes from wild-caught North Atlantic cod, haddock and pollock — never farmed. Full comparison: the science of collagen.
Our collagen lemon water is made for adults — women and men — who want an easy daily collagen routine. It has no added sugar and no preservatives, is Non-GMO Project Verified, and has just 35 calories a sachet. It contains fish, so it isn't suitable for anyone with a fish allergy. As with any supplement, if you are pregnant, nursing or have a medical condition, check with your healthcare provider first.
Yes — it contains fish. Our marine collagen comes from wild-caught cod, haddock and pollock, so it isn't suitable for anyone with a fish allergy. It's Non-GMO Project Verified and contains no preservatives. For the full ingredient list, see the Supplement Facts panel in the product images.
Collagen works gradually, so consistency matters more than dose. In clinical studies of collagen peptides, improvements in skin hydration and elasticity were measured after 4 to 12 weeks of daily use, and results were larger after 8 weeks or more, which is why our bundles follow the 8- and 12-week cadence.
You can purchase Lemon & Co. Collagen Elixir directly from our official website — one-time or with a subscription — on Amazon, and at Ulta Beauty, where we are part of the Wellness by ULTA Beauty collection. For the best value, choose our 8-Week Bundle or 12-Week Bundle.
