Study Notes

Sodium

Sodium is essential for blood control.
Table salt (sodium chloride) is the most common form of ingested sodium.
Kidneys regulate the body's sodium levels, with 98% of sodium loss occurring through urine.
Aldosterone plays a role in sodium regulation by increasing tubular re-absorption.
Hypernatremia is characterized by an excess of sodium in blood, leading to symptoms such as seizures, edema, and muscle weakness.

Magnesium

Magnesium is found in hard water, spices, and various fruits and vegetables.
It supports bone health and regulates cardiac function, muscle, and nerve activity.
Deficiency symptoms include hypomagnesemia and neuromuscular irritability.
Toxicity can lead to hypotension, respiratory failure, and cardiac disturbances.

Potassium

Found in milk, meat, and certain fruits.
Essential for normal heart functioning.
Plays a role in skeletal muscle function.
Required for many enzyme reactions, including Glycogenesis.
Insulin increases potassium uptake by cells, potentially leading to low plasma potassium levels.
Hypokalemia, characterized by low potassium, can result in paralysis and cardiac disturbances.
Hyperkalemia, characterised by high potassium, can also lead to paralysis and cardiac disturbances.

Phosphorus

Obtained from legumes, nuts, grains, and animal products.
Absorption may be affected by phytic acid (found in plant-based diets) and dietary fiber.
Trace elements should not be taken as dietary supplements due to potential toxicity.

Essential Amino Acids

Must be obtained through diet as the body cannot synthesize them.
Needed for protein synthesis, hormone production, and other vital functions.

Histidine

Precursor to histamine, a neurotransmitter involved in immune response, digestion, and sleep-wake cycles.
Supports red and white blood cell production and maintains the myelin sheath around nerve cells.

Isoleucine

One of the branched-chain amino acids (BCAAs).
Vital for muscle metabolism, immune function, and energy production.
Promotes muscle recovery, regulates blood sugar levels, and aids in wound healing.

Leucine

A potent trigger for muscle protein synthesis.
Supports muscle recovery, regulates blood sugar levels, and aids in wound healing.

Lysine

Essential for collagen synthesis for skin, bone, and connective tissue.
Supports immune function, calcium absorption, and hormone production.

Methionine

Contains sulfur, essential for protein structure.
Required for protein synthesis, cell growth, and formation of sulfur-containing compounds.

Phenylalanine

Precursor for dopamine and norepinephrine.
Plays a role in mood regulation, cognitive function, and alertness.

Threonine

Required for protein synthesis and collagen production.
Supports immune function, fat metabolism, and proper nervous system function.

Tryptophan

Precursor for serotonin, a neurotransmitter regulating mood, sleep, and appetite.
Supports relaxation, improves mood, and may benefit sleep quality.

Valine

A BCAA crucial for muscle metabolism, tissue repair, and energy production.
Supports muscle growth, tissue repair, and cognitive function.

Dietary Fiber Benefits

Promotes digestive health, preventing constipation and supporting a healthy gut microbiome.
Lowers LDL cholesterol and reduces heart disease risk.
Helps regulate blood glucose levels.
Promotes satiety and aids in weight management.

Plant-Based Supplements

Derived from herbs and botanicals.
Harness the therapeutic properties of plants.

Turmeric (Curcumin)

Anti-inflammatory and antioxidant properties.
Supports joint health and may promote digestive health.
Available in capsules, extracts, and teas.

Ginseng

Adaptogen, supporting stress management, energy levels, and immune function.
Available in capsules, teas, and extracts.

Echinacea

Supports the immune system, particularly during cold and flu seasons.
Available in capsules, tinctures, and teas.

Ashwagandha

Adaptogen, potentially reducing stress, improving mood, and enhancing energy levels.
Available in capsules, powders, and extracts.

Milk Thistle

Supports liver health and detoxification.
Available in capsules and extracts.

Garlic

Supports cardiovascular and immune health.
May have anti-inflammatory effects.
Available in capsules and aged garlic extracts.

Valerian Root

Promotes relaxation and sleep quality.
Available in capsules, teas, and extracts.

Green Tea Extract

Rich in antioxidants.
Supports metabolism and may offer cognitive benefits.
Available in capsules, teas, and extracts.
