Collagen: 2.5 g or 10 g a day, how to choose?
Partager
The number catches the eye. The formula deserves your full attention.
2,500 mg, 5,000 mg, 10,000 mg… Collagen supplements come with a wide range of dosages. To choose the one that suits you, take the time to look at the amount of collagen, the peptides used and the ingredients that come with it.
At FooDly, one dose brings together 2,500 mg of hydrolysed marine collagen, 50 mg of hyaluronic acid, 160 mg of vitamin C, vitamin E, eight B vitamins and myo-inositol. A combination to discover ingredient by ingredient, in a forest fruit flavour that fits easily into your daily routine.
2.5 g or 10 g: understanding collagen dosages
Start with the daily dose
The first benchmark is the amount of collagen provided by the recommended daily serving. On a label, remember to distinguish the total weight of powder from the amount of collagen it contains.
For FooDly, the information is precise:
- 2.96 g of powder per daily dose;
- 2.5 g of hydrolysed marine collagen in that dose;
- 30 doses per jar.
A product providing 10 g of collagen per day supplies a larger amount of this ingredient. To compare products as a whole, also look at the associated nutrients, the information on the peptides, the taste and the cost per serving.
Link the dosage to the peptides that were studied
Research on collagen examines identified ingredients, at specific doses and for specific durations. A trial published in 2014, for example, studied specific peptides at 2.5 g and 5 g per day for eight weeks.[1]
To interpret a study, always look at the peptide reference, the amount used and the outcomes assessed together. This reading gives meaning to the dosage and makes it possible to compare products on concrete criteria.
Look at what each formula provides
The FooDly formula combines a clearly stated amount of collagen with vitamins whose nutritional roles are established: normal collagen formation with vitamin C, maintenance of normal skin with vitamins B2, B3 and biotin, protection of cells from oxidative stress with vitamin E.[2]
These functions explain the value of the vitamins present alongside the collagen and give you benchmarks for choosing your supplement.

Marine collagen, hyaluronic acid and vitamin C: understanding the combination
Hydrolysed marine collagen: 2,500 mg
Collagen is the main ingredient of the FooDly formula. Of marine origin, it is supplied in hydrolysed form: the collagen has been broken down into peptides, which are shorter chains of amino acids.
This tells you about the form of the ingredient. Each dose provides 2,500 mg of marine collagen peptides, in a constant amount to follow day after day.
Hyaluronic acid: 50 mg
Hyaluronic acid is a compound naturally present in the body, particularly in the skin. In tissues, it has the ability to retain water: this is one of its characteristic biological properties.[3]
FooDly combines 50 mg of hyaluronic acid with marine collagen. You therefore find both ingredients in a single preparation. The role described here concerns the hyaluronic acid present in tissues; the assessment of oral supplementation relies on studies of the specific dosage and formulation concerned.
Vitamin C: 160 mg, or 200% of the NRV
Vitamin C has a direct link with the body’s own collagen production: it contributes to normal collagen formation for the normal function of skin.[2][4]
This is a particularly relevant role in a formula containing collagen. FooDly provides both marine collagen peptides and this vitamin involved in its natural production.
Vitamin C also contributes to the protection of cells from oxidative stress and to the reduction of tiredness and fatigue.[2]
Vitamin E, B2, B3 and biotin: functions worth knowing
Vitamin E: 12 mg, or 100% of the NRV
Vitamin E contributes to the protection of cells from oxidative stress.[2] Its presence adds this nutritional function to the formula, alongside vitamin C.
With 12 mg per dose, FooDly provides 100% of the nutrient reference value for this vitamin.
Vitamin B2: 1.4 mg, or 100% of the NRV
Riboflavin contributes to the maintenance of normal skin. It also contributes to the protection of cells from oxidative stress.[2]
These roles explain its place in the skin-related nutritional part of the formula.
Vitamin B3: 16 mg, or 100% of the NRV
Niacin contributes to the maintenance of normal skin and to normal energy-yielding metabolism.[2]
It thus brings a skin-related function and a more general function linked to the body’s use of energy.
Biotin: 50 µg, or 100% of the NRV
Biotin contributes to the maintenance of normal skin and normal hair.[2] In FooDly, it appears under the name “vitamin B8” on the label.
It is particularly relevant for people looking for a formula that combines collagen with nutrients associated with skin and hair.
The other B vitamins: a complementary nutritional intake
The following vitamins broaden FooDly’s nutritional profile. Their functions relate in particular to energy metabolism, proteins and cell division.[2]
Vitamin B1: 1.1 mg, or 100% of the NRV
Thiamine contributes to normal energy-yielding metabolism and to the normal functioning of the nervous system. It provides this general nutritional support within the daily dose.
Vitamin B5: 6 mg, or 100% of the NRV
Pantothenic acid contributes to normal energy-yielding metabolism and to the reduction of tiredness and fatigue. It completes the formula’s profile with energy-related functions.
Vitamin B6: 1.4 mg, or 100% of the NRV
Vitamin B6 contributes to normal protein and glycogen metabolism. It also contributes to the reduction of tiredness and fatigue. Its value in the combination lies in these general metabolic functions.
Vitamin B9: 200 µg, or 100% of the NRV
Folate contributes to normal amino acid synthesis and has a role in the process of cell division. It completes FooDly’s B vitamin intake.
Vitamin B12: 2.5 µg, or 100% of the NRV
Vitamin B12 contributes to normal energy-yielding metabolism and to the reduction of tiredness and fatigue. It also has a role in the process of cell division.
Myo-inositol: 10 mg
Myo-inositol is a compound naturally present in the body. Its derivatives are involved in particular in membranes and cell signalling, as studied in cell biology research.[5]
On the FooDly label, it is listed as “B7 — inositol”. The formula contains 10 mg per dose, shown separately from the vitamins that have an NRV. Its presentation in this article concerns its identity and its general biological role.
Why choose a formula combining several ingredients?
A combined formula brings several intakes together in one daily preparation. With FooDly, you get:
- Hydrolysed marine collagen, at 2,500 mg per dose.
- Hyaluronic acid, at 50 mg per dose.
- Vitamin C, for its role in normal collagen formation.
- Vitamins B2, B3 and biotin, for their contribution to the maintenance of normal skin.
- Vitamin E, for its contribution to the protection of cells from oxidative stress.
- The other B vitamins, for their general nutritional functions, detailed above.
You can therefore choose based on the full set of intakes that matter to you. Every amount is shown, every role is explained.
