Vitamins and minerals
Vitamins and minerals for athletes at JustLoading come down to two nutrients in three formats: vitamin C alone as a tablet, a tablet that combines collagen, magnesium and vitamin C, and marine collagen powder with both.
To choose quickly: if you only want vitamin C, go for the 500 mg tablet. If you prefer several ingredients together, take the collagen tablet with magnesium and vitamin C. If you don't like pills, try the red berry powder, which dissolves in water. For muscle mass, see proteins; for short, intense efforts, creatine.
Everything is JustLoading's own brand, and each product page lists the amount per dose, the percentage of the NRV and the allergens.

Vitamins and minerals for athletes
Vitamins and minerals for athletes are measured in milligrams and as a percentage of the NRV, the daily reference value. Here you'll find vitamin C alone or with collagen and magnesium. An authorized health claim only applies if the dose reaches 15% of the NRV, which is why every product page shows it.

Which one to choose
The three products share nutrients and differ in format and in how many ingredients they contain.
Vitamin C only
The 500 mg vitamin C tablet is the single-ingredient option. It gives 500 mg per tablet, 625% of the NRV, and the label says one a day. It suits anyone who already knows they want vitamin C and nothing else.
Several ingredients at once
The collagen tablet with magnesium and vitamin C is taken three a day, one with each main meal and with water. That dose adds up to 1,950 mg of collagen, 60 mg of vitamin C (75% of the NRV) and 57 mg of magnesium (15%).
You don't like pills
Marine collagen powder dissolves in water: one 10 g scoop in 200 ml, red berry flavor. According to the nutrition table, each scoop provides about 20 mg of vitamin C and about 94 mg of magnesium, 25% of the NRV for each.
What can be said about each nutrient
In the EU a label can only use authorized claims, and each one requires a minimum amount per dose.
In two products
Magnesium
Magnesium contributes to the reduction of tiredness and fatigue, to normal muscle function, to the normal functioning of the nervous system and to electrolyte balance. The dose has to be a source of magnesium: at least 56.25 mg, 15% of the NRV of 375 mg.
In all three
Vitamin C
Vitamin C contributes to normal collagen formation for the normal function of bones, cartilage, skin and teeth, to the reduction of tiredness and fatigue and to the protection of cells from oxidative stress. It needs at least 12 mg per dose, 15% of the NRV of 80 mg.
No claim
Collagen
Collagen has no authorized health claim, so here it is described as an ingredient with no effects attributed to it. What does have claims is what comes with it in the formula: vitamin C and magnesium.
What to check before you buy
What to look for on the label of any vitamin or mineral, from JustLoading or another brand.
The amount per dose
What matters is what one dose provides, not the pack size. The combined tablet gives its table per three tablets, and the powder gives it per 100 g and per 100 g of drink. To compare, bring everything to the daily dose.
The percentage of the NRV
The NRV is the daily reference value: 80 mg for vitamin C and 375 mg for magnesium. An authorized claim depends on the dose reaching at least 15% of that figure. Below it, the product cannot use the claim.
When a dose goes far beyond it
The 500 mg in the vitamin C tablet is 625% of the NRV, many times the reference value. The label says one tablet a day, asks you not to exceed the recommended daily dose and reminds you that a supplement does not replace a varied diet.
Origin and allergens
The collagen in the tablets comes from pork and the collagen in the powder from fish, so neither is vegetarian. The vitamin C tablet is listed as vegetarian. Possible traces are on each product page.
Tip: if you're torn between tablet and powder, think about how many doses fit your day. The combined product is three tablets a day, one with each main meal; the powder is one 10 g scoop in 200 ml of water. More context in healthy supplements.
Vitamins and minerals FAQ
Which vitamins are good for muscles?
In the EU, vitamin D has an authorized claim for muscles: it contributes to the maintenance of normal muscle function. Magnesium, calcium and potassium contribute to normal muscle function. The range has magnesium, inside the combined tablet and the collagen powder. Muscle mass depends on protein and training.
What is the best multivitamin for athletes?
JustLoading doesn't sell a multivitamin: the range has vitamin C and magnesium. If you compare one from another brand, check the NRV percentage of each nutrient per daily dose and that each vitamin comes with its amount. A multivitamin only makes sense if your diet leaves a gap you can point to.
Which vitamins and minerals does an athlete need?
The same as any adult, in similar amounts, as long as they eat a varied diet. The International Olympic Committee's consensus statement on supplements recommends correcting confirmed deficiencies and not supplementing blindly. If your diet is narrow, a blood test shows what is missing, and you can then cover it with food.
What is the 500 mg vitamin C for?
It carries the authorized claims for vitamin C: it contributes to normal collagen formation, to the reduction of tiredness and fatigue and to the protection of cells from oxidative stress. Each tablet has 500 mg, 625% of the NRV, and the label says to take one a day with or without food.
How much vitamin C can I take a day?
Follow the label: one 500 mg tablet a day for the vitamin C product. The reference value is 80 mg, so that tablet already goes far beyond it. Count the vitamin C that comes from food and from the combined product too, and check with a professional if you take medication.
How do I take the collagen with magnesium and vitamin C?
Take three tablets a day, preferably one with each main meal and with water. The label allows taking them in the morning, on an empty stomach or before bed. The 180-tablet pack lasts 60 days at that dose. That dose provides 60 mg of vitamin C and 57 mg of magnesium.
What is in the marine collagen powder?
It contains fish collagen (62%), maltodextrin, hyaluronic acid, vitamin C, magnesium and sweeteners, with a red berry flavor. According to the table, a 10 g scoop gives about 6 g of collagen, 20 mg of vitamin C and 94 mg of magnesium. It contains fish and may contain traces of gluten, egg, milk and soy.
Can I take vitamin C and the collagen with magnesium together?
You can, but the vitamin C adds up: 500 mg from the tablet plus 60 mg from the combined product's daily dose. Before adding them, check the total on both product pages and don't exceed the daily dose on either label. If you take medication, check with a professional first.
Does vitamin C help the immune system?
The authorized claim is that vitamin C contributes to the normal function of the immune system, and it requires the dose to be a source of vitamin C. No claim says it makes immunity stronger. If a label promises more, that promise is not backed by an authorized claim.
Are vitamin D, omega 3 or zinc in the category?
Not for now. The category has three products, all with vitamin C and two of them with magnesium. If you want vitamin D or zinc, check the amount per dose and its NRV percentage on any brand's label before deciding.
