Vitamin B5 Deficiency
Assess whether you present clinical signs of vitamin B5 deficiency (pantothenic acid).
Vitamin B5, or pantothenic acid, takes its name from the Greek pantos (everywhere) because it is present in almost all foods. However, it is frequently insufficient in stressed individuals, as it is the direct precursor of coenzyme A (CoA), essential for cortisol synthesis by the adrenals. It also plays a role in fatty acid metabolism, wound healing, and hair health. This questionnaire targets the characteristic signs of B5 deficiency.
Points forts
- + Rapid identification of clinical signs
- + Simple self-assessment test
- + Detection of hair and neurological signs related to pantothenic acid deficiency
Limites
- - Does not replace blood testing
- - Some signs may have other causes
- - Limited sensitivity for subclinical deficiencies

Understanding the central role of coenzyme A
Vitamin B5 is the exclusive precursor of coenzyme A (CoA), a molecule involved in more than 70 essential metabolic reactions. CoA is indispensable for acetyl-CoA formation (crossroads of energy metabolism), fatty acid synthesis, production of adrenal steroid hormones, and acetylcholine synthesis. Your good current score reflects satisfactory functioning of these pathways, but requirements increase significantly during periods of stress.
Stress and adrenal exhaustion
The adrenal glands are the organs richest in vitamin B5 in the body. During chronic stress, the demand for CoA to synthesize cortisol increases significantly, which can quickly deplete your reserves. Watch for early signs of functional adrenal insufficiency: morning fatigue, difficulty managing stress, cravings for salt and sugar, drop in blood pressure when standing.
Preserving your B5 status
Regularly incorporate the richest sources of B5 into your diet: royal jelly, liver, egg yolks, shiitake mushrooms, and sunflower seeds. During periods of stress, increase your intake of avocado, sweet potato, and salmon. Adopt stress management practices (heart rate variability coherence, nature walks) to reduce adrenal CoA consumption and preserve your vitamin B5 reserves.

Pathophysiology of your situation
Coenzyme A (CoA), of which B5 is the exclusive precursor, is involved in more than 70 metabolic pathways. It is essential for acetyl-CoA production (Krebs cycle entry), fatty acid synthesis (cell membranes, myelin), synthesis of adrenal steroid hormones (cortisol, DHEA, aldosterone, progesterone), and acetylcholine synthesis (memory neurotransmitter). CoA deficiency causes global slowdown of these pathways, explaining the diversity of your symptoms.
Clinical and biological markers
Clinical signs according to Hertoghe include burning feet syndrome (burning sensations in feet and legs), diffuse hair loss, headaches, sleep disturbances, and tendency to bruise. In the laboratory, blood pantothenic acid testing (normal range 1.6 to 2.7 micromol/L) is the direct marker. Morning salivary cortisol testing (low if adrenals lack CoA for synthesis) and serum DHEA-S testing provide additional information on adrenal impact. Erythrocyte CoA levels can also be measured.
Priority food sources
Royal jelly is the most concentrated natural source (52 mg/100g), followed by organ meats (veal liver 7.2 mg/100g, poultry liver 6.7 mg/100g) and sunflower seeds (7.0 mg/100g). Egg yolks (2.99 mg/100g), shiitake mushrooms (3.6 mg/100g), avocado (1.4 mg/100g), and salmon (1.8 mg/100g) are accessible daily sources. Raw button mushrooms (1.5 mg/100g) provide complementary intake in salads.
Targeted supplementation
Calcium pantothenate (calcium D-pantothenate) at 500 mg per day is the standard supplementation form. For more targeted adrenal effect, pantethine (active form, 300 mg per day) is preferable as it converts directly to CoA without intermediate steps. Pantethine also has a beneficial effect on lipid profile (reduction of triglycerides and LDL-cholesterol). Preferably take in the morning to support the physiological cortisol peak. Combine with vitamin C (500 mg) which acts synergistically for adrenal function.
Stress management and lifestyle
The adrenal glands are the organs richest in vitamin B5 and vitamin C in the body. Chronic stress exhausts these reserves by massively mobilizing CoA to produce cortisol. Adopt a daily stress-reduction routine: heart rate variability coherence (3 times 5 minutes per day), nature walks, sleep before 11 PM. Avoid coffee after 2 PM (it stimulates the adrenals and increases CoA consumption). Moderate but regular physical exercise supports adrenal function without depleting it.
Adrenal support through plants
Blackcurrant bud (Ribes nigrum) in gemmotherapy is the reference for supporting the adrenal cortex. It mimics cortisol action (cortisol-like effect) without its side effects and stimulates natural cortisol and DHEA production. Dosage: 5 to 15 drops of concentrated glycerin macerate upon waking on an empty stomach. Eleutherococcus (Eleutherococcus senticosus), an adaptogenic plant, strengthens stress resistance and supports the adrenals. Licorice (Glycyrrhiza glabra) prolongs cortisol half-life, but is contraindicated in case of hypertension.

Understanding the severity of the situation
Severe vitamin B5 deficiency causes collapse of the coenzyme A pool, with cascading consequences throughout metabolism. Acetyl-CoA production falls, compromising the Krebs cycle and ATP production. Fatty acid synthesis is impaired, affecting cell membranes and nerve myelin sheath. The adrenals, deprived of CoA, can no longer correctly synthesize cortisol, DHEA, and aldosterone, leading to functional adrenal exhaustion. Acetylcholine production decreases, disturbing memory, concentration, and muscle tone.
Priority biological assessment
Request blood pantothenic acid testing (normal range 1.6 to 2.7 micromol/L) and complete with comprehensive adrenal assessment: salivary cortisol at 4 points (waking, noon, 4 PM, bedtime), serum DHEA-S, and aldosterone. According to Hertoghe, major clinical signs include burning feet syndrome (pathognomonic sign), diffuse hair loss, sleep onset insomnia, tension headaches, and spontaneous bruising. Low morning cortisol with collapsed DHEA-S suggests B5-dependent adrenal exhaustion. Erythrocyte CoA testing, though more specialized, directly confirms the deficiency.
Therapeutic diet
Daily integrate the most concentrated B5 sources: a course of fresh royal jelly (52 mg/100g) at breakfast, organ meats 2 to 3 times weekly (veal liver 7.2 mg/100g), 2 egg yolks daily (2.99 mg/100g), and shiitake or button mushrooms regularly. Sunflower seeds (7.0 mg/100g) as a snack and daily avocado supplement intake. Salmon, trout, and chicken are the best animal protein sources. Avoid aggressive cooking which partially destroys this thermosensitive vitamin.
Attack supplementation
Start with pantethine at 300 mg, twice daily (active form converting directly to CoA) for a minimum of 3 months. As alternative or complement, calcium pantothenate at 1000 mg daily (500 mg morning and noon) offers massive intake to rebuild reserves. Imperatively combine with vitamin C (1000 mg/day split into 2 doses) to support adrenal function. A complete B complex will prevent imbalances between B vitamins. Magnesium (300 mg bisglycinate) potentiates CoA action in ATP production. Take supplements in morning and noon, never in evening.
Lifestyle reform
The absolute priority is reducing chronic stress that exhausts your adrenals and CoA. Establish a non-negotiable stress-reduction routine: heart rate variability coherence upon waking and mid-day, 30-minute nature walks, sleep before 11 PM to respect cortisol circadian rhythm. Eliminate coffee (adrenal stimulant worsening exhaustion) and replace with matcha green tea (calming L-theanine). Practice gentle physical exercise (yoga, swimming, walking) without forcing. Avoid prolonged fasting and restrictive diets that stress the adrenals.
Phytotherapy adrenal protocol
Blackcurrant bud (Ribes nigrum) in gemmotherapy is essential: 15 drops of concentrated glycerin macerate upon waking on empty stomach for 3 months. It stimulates the adrenal cortex and possesses natural cortisol-like effect. Ashwagandha (Withania somnifera) in standardized extract (300 to 600 mg/day KSM-66) is the most studied adaptogenic plant for reducing excess cortisol and restoring the HPA axis (hypothalamic-pituitary-adrenal). Rhodiola (Rhodiola rosea) in dry extract (200 to 400 mg/day standardized in rosavines) complements adaptogenic effect. For sleep, linden bud (Tilia tomentosa) in gemmotherapy (15 drops at bedtime) promotes natural sleep onset.
