Vitamin B5, or pantothenic acid, is a water-soluble vitamin. It cannot be stored in fat. Vitamin B5 is found in nearly all foods, with high amounts in seeds and whole grains and in some varieties of stinging nettles (plants in the Urticacae or nettle family). Royal jelly is the natural product known to contain the most vitamin B5.
Vitamin B5 promotes skin and mucosa growth and resistance to stress or disease. It is necessary to metabolize carbohydrates, fats, and proteins and is instrumental in the synthesis of some hormones.
What does vitamin B5 do?
The data does not allow nutritionists to calculate a recommended dietary allowance (RDA). Adequate intake (AI) of pantothenic acid is considered to be the amount required to offset the B5 eliminated in urine.
Adequate Intake of Vitamin B5:
|Infants||Birth to 12 months||1.7mg to 1.8mg|
|1 to 8 years||2mg to 3mg|
|Preteens||9 to 13 years||4mg|
|Teens/adults||14 and older||5mg|
|Pregnant women|| ||6mg|
|Nursing mothers|| ||7mg|

Vitamin B5 deficiency is unlikely because B5 is found in virtually all foods. Vitamin B5 is sensitive to air, light, and heat, so freezing, canning, refining, and cooking destroy much of its content in food. An unvaried diet consisting mainly of processed foods and certain antibiotics can lead to a deficit in pantothenic acid.
Signs of vitamin B5 deficiency:
Large amounts of vitamin B5 are well tolerated by most people.
Signs of excess vitamin B5 (rare):
Natural health products and vitamin supplements:
Speak with your pharmacist if you plan to take B5 supplements. Your pharmacist can help you choose the solution that’s best for you based on your health and any drugs you take.
