How much collagen should you take per day? Most research on collagen peptides uses a daily amount somewhere between about 2.5g and 20g, and the right amount depends on your goal. A daily serving of 10 to 20g, which is one to two scoops of Yonder, sits comfortably inside that researched range. Below we break down how much collagen to take for skin, joints, and bones, how long it takes to work, and how to make it a habit that actually sticks.

Collagen dose by goal
How much collagen for skin
Skin studies tend to use smaller daily amounts and still see results over about 12 weeks. According to PubMed:
- A randomized, placebo-controlled trial in 72 women aged 35 and older found that 2.5g of collagen peptides per day for 12 weeks supported skin hydration, elasticity, and density (Bolke et al., 2019, Nutrients) (DOI).
- A randomized, double-blind trial in women aged 43 to 65 found that 5g of collagen peptides per day supported skin moisture and dermis density, with visible changes in elasticity within 28 days (Vleminckx et al., 2024, Journal of Cosmetic Dermatology) (DOI).
- A randomized, double-blind, placebo-controlled study found that a low-molecular-weight collagen peptide taken daily for 12 weeks supported skin hydration, elasticity, and the appearance of wrinkles (Kim et al., 2018, Nutrients) (DOI).
Collagen supports skin elasticity and hydration as part of a daily routine.
How much collagen for joints
Joint research generally uses a slightly higher daily amount. According to PubMed:
- A 12-week randomized controlled trial in active adults found that 5g of collagen peptides per day supported activity-related knee comfort compared with placebo (Zdzieblik et al., 2017, Applied Physiology, Nutrition, and Metabolism) (DOI).
- A double-blind randomized controlled trial in middle-aged active adults found that 10 to 20g of collagen peptides per day over 6 to 9 months supported daily-activity comfort and function (Kviatkovsky et al., 2023, Journal of the International Society of Sports Nutrition) (DOI).
Collagen supports joint comfort during normal daily activity.
How much collagen for bones
Bone research points to a modest daily amount taken over a longer stretch. According to PubMed:
- A 12-month randomized, double-blind, placebo-controlled study in postmenopausal women found that 5g of specific collagen peptides per day supported bone mineral density in the spine and femoral neck (Konig et al., 2018, Nutrients) (DOI).
Collagen supports bone health, particularly for women navigating midlife.
Can you take too much collagen?
Across these studies, daily amounts from about 2.5g up to 20g were well tolerated, with no adverse effects reported. Collagen is a food-based protein, so most people simply pick the amount that matches their goal and their routine rather than chasing a maximum. If you have a health condition or take medication, it is always worth checking with your provider first.
How long does it take to work?
Most collagen studies run 8 to 12 weeks before measuring changes, and the bone and joint studies run longer still. So the exact number of grams matters less than showing up every day for a couple of months. Give it real time before you judge it.
How much is in Yonder, and how to take it
Yonder delivers 10 to 20g of collagen per one to two scoops, plus a bonus 9 to 18g of clean protein. Because it is flavorless, it disappears into coffee, a smoothie, soup, or almost any recipe without changing the taste, which is the whole point: the easiest habit is the one you will actually keep. We stir ours into our morning coffee most days. Yonder is grass-fed sourced, third-party tested for purity, and certified Glyphosate Residue-Free by The Detox Project. One ingredient, no fillers.
Frequently Asked Questions
How many grams of collagen should I take a day?
Most research uses between 2.5g and 20g per day depending on the goal. A daily serving of 10 to 20g, or one to two scoops of Yonder, fits the researched range and is easy to stay consistent with.
Is it better to take collagen once a day or split it up?
Either works. What matters most is taking it every day. Many people take their full serving at once in a morning coffee or smoothie because it is the easiest to remember.
How much collagen should a woman over 40 take?
The same 10 to 20g daily range works well. Because natural collagen production declines with age, a consistent daily habit is what makes the difference over time.
How long before I notice a difference?
Most studies measure changes at 8 to 12 weeks, so give it a couple of months of daily use.
Is more collagen better?
Not necessarily. Studies show benefits across a range of amounts, and higher amounts were well tolerated but not always more effective. Pick the amount that matches your goal and stay consistent.
Can I take collagen with other supplements?
Yes. Collagen is a single-ingredient protein that pairs fine with a typical routine. If you take medication or have a health condition, check with your provider first.

How much collagen per day for a woman?
There is no separate dose for women. Most research on skin, hair, nail, joint, and bone benefits uses about 10 to 20g of collagen a day, which is one to two scoops of Yonder. Many women find one scoop stirred into morning coffee is the easiest way to stay consistent.
Why don't collagen supplements always work?
Usually it comes down to dose and quality. Some products hide a tiny amount of collagen under fillers or use a low-quality source, so you never get a meaningful 10 to 20g of clean collagen a day. Consistency matters too, since collagen supports skin, hair, nails, joints, and bones as part of a daily routine and results build over weeks. Yonder is single-ingredient, grass-fed, third-party tested, and delivers a full 10 to 20g per one to two scoops.
Will collagen peptides break a fast?
Collagen peptides contain protein and calories, so they will break a strict fast. A single scoop is low-calorie, so many people add it during their eating window or to coffee once they are eating again.
