Connu pour soutenir la fonction respiratoire. Il est parfois utilisé par des athlètes afin d’aider la respiration et la récupération.
Utilisés largement pour favoriser la réparation musculaire et la récupération après l’entraînement.
L’un des suppléments sportifs les plus étudiés pour améliorer la force et la performance.
sucre et électrolytes. Ces formulations peuvent soutenir l’hydratation et la performance lors
d’efforts d’endurance prolongés, comme les marathons.
Cela peut contribuer à :
Une fois séché, l’échantillon peut rester relativement stable pendant un certain temps.
Une petite carte peut être envoyée beaucoup plus facilement qu’un tube de sang liquide.
Quelques gouttes suffisent pour certaines analyses.
La méthode est pratique là où l’accès à une clinique ou à un laboratoire est limité.
La technologie n’est pas du « n’importe quoi », mais certaines entreprises peuvent parfois aller plus loin que ce que les données scientifiques justifient vraiment. Autrement dit, la méthode est sérieuse, mais certaines promesses marketing méritent d’être examinées avec prudence.
Le concept est solide sur le plan scientifique. Ce qui demande le plus d’esprit critique, ce n’est pas l’existence de la méthode elle-même, mais plutôt la façon dont certains tests sont présentés, interprétés ou commercialisés.

Supplements, Performance & Health
1
Supplements Commonly Discussed
• NAC (N-acetylcysteine): Known to support respiratory function; used by athletes to help with breathing and recovery.
• Protein Supplements: Widely used to support muscle repair and recovery after training.
• Creatine: One of the most studied sports supplements for improving strength and performance.
2. New Developments & Natural Support
Major advances have been made in sports drinks and supplements combining sugar and electrolytes, which help support hydration and endurance performance (think : marathons).
Beets (Beetroot)
Rich in nitrates that increase nitric oxide, which can improve blood flow, support endurance, and help lower blood pressure. Available as whole food, capsules, or crystals/powders.
Health Monitoring: Dried Blood Spot (DBS)
Instead of drawing a vial of blood from a vein, a person pricks a finger, places drops of blood on filter paper or a special card, lets it dry, and mails it to a lab. This method has been used since the 1960s, famously for newborn screening (the heel-prick test).
Why it works scientifically
When blood dries on specialized paper, many molecules remain chemically stable. Labs can re-hydrate the sample and measure substances using mass spectrometry or immunoassays.
Reliable Markers:
- Vitamin D & HbA1c
- Certain Hormones
- Fatty Acids (Omega-3)
- Metabolic & Genetic markers
Less Reliable For:
- Full metabolic panels
- Electrolytes (Sodium/Potassium)
- Many Enzymes
- Inflammatory markers (CRP)
Note: If a company claims 50+ biomarkers from a finger drop, skepticism is reasonable. Many kits are not diagnostic and interpretations can be exaggerated.
Organization: Hungry Wire Academy
A non-profit organization focused on helping men improve Mental, Physical, and Spiritual health through retreats and educational programs. Inspired by figures like David Goggins (mental resilience) and Pierre Lavoie (endurance/health advocacy).
Experience: Approximately 10 years with the Canadian Forces in a performance and training context with a biomedical approach to health.
Why Perform Blood Tests?
- Monitoring biomarkers of health is part of a good preventative strategy
- Persons can be asymptomatic but have underlying issues (ex: LDL)
- Tracking nutritional status and biomarkers over many years is valuable information
- Identifying deficiencies or risk factors

Discussion question raised
-
Why perform blood tests?
Possible reasons include:-
Monitoring biomarkers of health
-
Tracking nutritional status
-
Evaluating training adaptation
-
Identifying deficiencies or risk factors
-
The technique is called Dried Blood Spot testing (DBS).
Instead of drawing a vial of blood from a vein, a person:
-
Pricks a finger
-
Places drops of blood on filter paper or a special card
-
Lets the blood dry
-
Mails the card to a lab
-
The lab extracts and analyzes the dried sample.
This method has actually been used since the 1960s in medicine.
A famous example is newborn screening, where babies are tested for genetic diseases using a heel-prick blood spot.
Why it works scientifically
When blood dries on specialized filter paper:
-
many molecules remain chemically stable
-
the sample can be re-hydrated and analyzed
-
labs can measure substances using mass spectrometry or immunoassays
So the basic science is legitimate.
What it can measure fairly well
Some markers work quite well with dried blood spots:
Examples:
• Vitamin D
• HbA1c (diabetes marker)
• Certain hormones
• Fatty acids (omega-3 index)
• Some infectious disease tests
• Genetic screening
• Certain metabolic markers
Many research studies use DBS because it’s easy to collect in the field.
What it does NOT measure well
This is where marketing can drift into over-selling.
Finger-prick dried samples are not ideal for many standard blood tests.
Problems include:
-
small sample volume
-
uneven drop size
-
drying variability
-
contamination
-
differences between capillary blood vs venous blood
Tests that often perform poorly or inconsistently with DBS include:
• full metabolic panels
• electrolytes (sodium, potassium)
• many enzymes
• some hormones
• inflammatory markers like CRP (sometimes unreliable)
So if a company claims 50+ biomarkers from a finger drop, skepticism is reasonable.
Another important limitation
Many direct-to-consumer kits:
-
are not diagnostic
-
may not be regulated the same way as hospital labs (in reality, the majority are not)
-
sometimes provide interpretation that is questionable
The lab measurement might be valid, but the health interpretation can be exaggerated.
