Bones & Joints

Muscles Supplement Vial – Triple Magnesium

One mineral, three forms, your whole workday covered.

THE FACT

3 in 5 workers in the EU report pain or discomfort in their muscles, bones or joints related to their work¹.

SOUND FAMILIAR?

You reach the end of the day with heavy legs, tense shoulders, and trouble focusing on that last meeting.

You assume it’s just normal tiredness but your body might be asking for something very specific.

THE BRIDGE

That’s why Muscles Supplement Vial – Triple Magnesium exists: a magnesium supplement designed for end-of-day fatigue, in a single dose.

Origin / why

We chose a triple-magnesium blend — citrate, pidolate, and sulfate — for a comprehensive formula. One morning dose, designed to support you throughout the day.

“If tiredness tends to hit every afternoon, look at your day as a whole. Long hours sitting, too few breaks, unbalanced meals or not getting enough sleep can all add to fatigue. Taking care of these habits, together with an adequate intake of nutrients such as magnesium, can help address tiredness from several angles.”

Joint structure

WHY DOES IT WORK? Hydrolysed collagen for joints has been studied for its possible role in maintaining joint cartilage².
WHAT IS IT? Collagen is the most abundant protein in joint cartilage. Joints – Collagen & Hyaluronic includes it hydrolysed, of bovine origin, to make it easier to digest.
WHY DOES IT WORK? Chondroitin sulfate is one of the most studied cartilage components in relation to joint health³.
WHAT IS IT? Chondroitin sulfate is a natural component of joint cartilage, made up of sugar chains.
WHY DOES IT WORK? Glucosamine sulfate has been extensively studied in relation to joint health³.
WHAT IS IT? Glucosamine is a natural component of cartilage. In Joints – Collagen & Hyaluronic it comes from crustaceans.

Collagen formation — Vitamin C

WHY DOES IT WORK? Vitamin C contributes to normal collagen formation for the normal function of cartilage and bones¹: it’s needed for the body to produce it naturally.
WHAT IS IT? Vitamin C is a water-soluble vitamin that the body can’t produce on its own. Joints – Collagen & Hyaluronic provides it as sodium ascorbate.

Bone health

WHY DOES IT WORK? Vitamin D contributes to the maintenance of normal bones¹, helping the body use calcium correctly.
WHAT IS IT? Vitamin D3 (cholecalciferol) is the form of vitamin D the body produces through sun exposure, and which can also come from diet or a vitamin D3 supplement.
WHY DOES IT WORK? Vitamin K2 contributes to the maintenance of normal bones¹: it plays a part in how the body fixes calcium in bone.
WHAT IS IT? Vitamin K2 (menaquinone-7) is a form of vitamin K. Joints – Collagen & Hyaluronic includes it as menaquinone-7 (MK-7).

Additional support

WHY DOES IT WORK? MSM has been studied for its possible role in joint wellbeing⁴.
WHAT IS IT? MSM is an organic sulfur compound naturally present in plants, animals and the body itself.
WHY DOES IT WORK? Hyaluronic acid has been studied for its possible relationship with joint lubrication⁵.
WHAT IS IT? Hyaluronic acid is a substance the body produces naturally, present in the fluid that lubricates joints. Joints – Collagen & Hyaluronic includes it as sodium hyaluronate.
WHY DOES IT WORK? Turmeric is one of the most researched plants in relation to joint wellbeing⁶. Curcumin is one of its most notable components.
WHAT IS IT? LTurmeric comes from the rhizome of Curcuma longa, a plant in the ginger family. Curcumin, one of its most studied compounds, is extracted from it. Joints – Collagen & Hyaluronic includes it as a concentrate of this rhizome.
WHY DOES IT WORK? Nettle extract is a traditional ingredient in joint preparations
WHAT IS IT? Nettle (Urtica dioica) is a plant whose root is traditionally used in this type of preparation. Joints – Collagen & Hyaluronic includes its extract in dried form.
WHY DOES IT WORK? Fish oil is a source of omega-3 fatty acids, a widely studied type of fat.
WHAT IS IT? Fish oil is a source of long-chain omega-3 fatty acids (EPA and DHA).
WHY DOES IT WORK? Vitamin E contributes to the protection of cells from oxidative stress¹, helping to neutralise the oxidative damage that occurs naturally in the body.
WHAT IS IT? Vitamin E is a fat-soluble vitamin with antioxidant properties. Joints – Collagen & Hyaluronic provides it as DL-alpha-tocopheryl acetate.

Education

01

Eye-opening fact

2.4 billion people worldwide (31% of the global population) fall short of adequate magnesium intake¹.

02

Myth vs. reality

Myth:
“All magnesium supplements have a laxative effect.”

Reality:
It depends on the chemical form. Magnesium oxide, for example, is barely absorbed (around 4%), and that excess can trigger the well-known laxative effect. Citrate and pidolate (both in Muscles – Triple Magnesium) are better absorbed and less likely to cause it.²,³

03

Top ingredient (fun fact

Most of the magnesium in your body (50-60%) is stored in your bones. That’s why this mineral has as much to do with bone health as it does with energy, muscles or rest.³

04

9to5 tip

Fatigue can take many forms. That’s why supporting your energy starts with taking care of several key pillars, such as rest, nutrition, movement, and essential micronutrients.

FAQs

Why isn’t it recommended during pregnancy or breastfeeding?

Sodium cyclamate, one of the sweeteners in the product, is not recommended during pregnancy or breastfeeding. If you’re in this stage, check with your doctor before taking it.

Can I take it if I have kidney problems?

No, if you have moderate-to-severe renal impairment. Kidneys that don’t filter properly can allow magnesium to build up in the blood. Check with your doctor.

I take diuretics or antibiotics, is that a problem?

With diuretics, it’s worth monitoring your magnesium levels with your doctor. With antibiotics (tetracyclines, fluoroquinolones) or bisphosphonates, space your dose at least 2-4 hours apart so neither interferes with the absorption of the other.

Why triple-source magnesium instead of just one form?

Each form contributes something different: citrate dissolves and is absorbed easily, pidolate is better retained inside cells, and sulfate provides more elemental magnesium per dose. Together, they maximize what your body actually uses.

When should I take it?

Once a day, ideally in the morning. A single dose, so it’s easy to fit into your daily routine.
