Collagen Fit and Collagen Plus sit close enough in price to make the choice confusing. Is Plus worth the extra money, or does Fit give you what you need?
The decision comes down to what you want from your daily scoop: a straightforward addition to an active routine, or a supplement built around a beauty-focused routine. Here is how we would choose.
Why Collagen Fit gets our vote
For a reader already interested in collagen, Fit has a persuasive combination of value, flexibility and testing. Its unflavored format makes it the more logical choice for an existing beverage routine, while NSF Certified for Sport gives athletes a concrete reason to prefer it.
That certification addresses prohibited substances, label contents and contaminants. Those are useful checks when a supplement is part of your regular routine; they are a stronger buying reason than a long list of benefits on the front of a tub. See what NSF checks.
Fit is the option we would shortlist for someone who trains regularly and wants a collagen product without paying for beauty-focused additions. That is our judgment about the package as a whole, rather than a claim that it produces better recovery results than Plus.
What is collagen useful for?
Collagen is a structural protein found in connective tissues, including skin, tendons and cartilage. Collagen peptides are smaller pieces of that protein used in supplements. The interest for active people centers on connective tissue and joint comfort.
There is some encouraging research behind that interest. A 12-week placebo-controlled study in 139 athletic participants with activity-related knee discomfort found a greater reduction in activity-related pain with specific collagen peptides. It tested a particular ingredient, not either Thorne blend, so it supports the rationale for collagen rather than proving these tubs deliver the same result. Study details.
Our take: collagen has a more relevant role as a targeted addition for that interest than as an all-purpose post-workout powder. If your main aim is getting enough protein for muscle recovery, start with a suitable protein powder; collagen can serve a separate purpose.
What Collagen Plus adds—and who might benefit
Why put berry extract and peach ingredients in a collagen powder? Thorne positions Plus around skin appearance and hydration. The extras give it two specific aims: smoother-looking skin and better moisture retention. That makes Plus worth a closer look if skin care is part of your reason for buying collagen. Thorne’s formula and product description.
Currant extract: the skin-appearance ingredient
MitoHeal is a concentrated blend of redcurrant and blackcurrant extracts. These berries contain polyphenols, plant compounds studied for their biological effects. In this formula, their attraction is the possibility of improving the appearance of skin—not adding more protein.
There is some human evidence behind that idea. A small, randomized, placebo-controlled pilot study enrolled 40 adults and tested MitoHeal at 500 mg or 1,000 mg daily for 30 days. Researchers reported improvements in photographed skin quality and participants’ satisfaction compared with placebo. Plus contains 500 mg per serving, matching the lower amount studied. Read the MitoHeal study.
Our view: this gives the currant ingredient a more useful foundation than a vague “antioxidant” promise. It is an encouraging early result, though one small, short study does not establish lasting changes or prove the finished Thorne blend works the same way.
Peach-derived ceramides: the moisture-retention ingredient
Ceramides are fats naturally present in the skin’s outer barrier. Think of them as part of the mortar between skin cells: they help the barrier hold on to water. HydroPeach is a peach-derived ingredient supplying related plant compounds called glucosylceramides. Its intended benefit is better hydration and less dry, rough-feeling skin.
A small study of peach-derived glucosylceramides reported improved moisture retention over 20 days. But it involved just 26 people, with only three in the control group, so the evidence is preliminary. It supports the idea behind the ingredient; it does not establish how much difference a scoop of Plus will make. Read the peach-ceramide research.
A label detail worth understanding: the listed 20 mg is the HydroPeach peach-extract ingredient, not a statement that it contains 20 mg of pure ceramides.
Are those extras worth paying for?
We would shortlist Plus for someone who wants collagen specifically for skin appearance and hydration, and likes the convenience of one flavored drink. Its ingredients have a coherent purpose, with some early human evidence behind them. That is a reasonable reason to spend more if those benefits matter to you.
For a reader mainly interested in an active routine, Fit remains our better-value pick. The extras in Plus do not give us a reason to expect better workout recovery. Choose Plus for its skin-focused formulation; choose Fit when that is not your priority.

The premium is modest—but it should buy something you want
Plus costs $11 more per tub, around 37 cents extra per serving. Across twelve tubs, the difference is $132. These calculations use the listed serving sizes, not a personal dosing recommendation.
Our value judgment favors Fit. For a buyer interested primarily in collagen, spending less while getting more of the main ingredient is an easy advantage to understand. More grams do not automatically produce better results, but the extra ingredients need to earn their place in your budget.
A useful buying example: if you already have a drink you enjoy and simply want to add collagen, we would choose Fit. If you are specifically shopping for a flavored collagen-and-botanical beauty blend, Plus is the relevant option. Those are different purchases, even though the tubs share a brand.
The amino-acid question, explained simply
Collagen already contains amino acids: they are the building blocks of the protein itself. That is different from a separate essential-amino-acid blend. The phrase “contains amino acids” does not tell you whether a powder is the best choice for muscle recovery.
A short randomized trial in 31 older men found that extra whey or pea protein increased the measured rate of muscle-protein building, while collagen did not. The study was not a test of these Thorne products or long-term muscle gains, but it illustrates why protein source matters. Read the research.
For that reason, we would choose a suitable protein powder first when the goal is filling a dietary protein gap. Our gluten-free protein guide covers that decision.
NR and betaine: useful to understand, not a deciding factor
Nicotinamide riboside, or NR, helps the body make NAD+, a molecule involved in cellular metabolism. A manufacturer-funded eight-week trial found that NR raised blood NAD+ levels; that is different from demonstrating faster workout recovery. NR study.
Both powders contain the same listed amounts of NR and betaine, also called trimethylglycine. Whatever your interest in those ingredients, they do not distinguish the two products. We would base the purchase on the collagen, format, testing and extra ingredients instead.
Our assessment for gluten-free shoppers
Both products carry Thorne’s gluten-free designation, supported by the company’s stated practice of annual outside-laboratory testing of product samples. That gives us a documented basis for including them in this comparison. It is manufacturer testing information, not a separately verified gluten-free certification or a result for every individual tub. Thorne’s testing explanation.
Fit has the additional sport-certification advantage. The NSF record checked covers the US unflavored 506 g product and named lots; athletes relying on that certification should match their purchase to the listing. Sport certification and gluten-free certification answer different questions.
Neither option earns a universal “celiac-safe” guarantee. For a fuller explanation of labels and testing, see our gluten-free supplement guide.
Our recommendation
Buy Fit for the stronger overall value in this comparison. Consider Plus for its specific beauty-focused formula. For most RecoverFitNow readers shopping for collagen to accompany an active lifestyle, Fit is where we would start.
