Daily Thiamin Needs:
- Men (19-64 years): 1mg per day
- Women (19-64 years): 0.8mg per day
Most individuals can obtain sufficient thiamin through a balanced diet. Thiamin is not stored in the body, so daily intake is important.
Thiamin Supplementation:
Generally, supplementation is not necessary for most people. High doses of thiamin supplements have not been extensively studied for adverse effects, but it’s always best to prioritize food sources.
Riboflavin (Vitamin B2): Supporting Skin, Eyes, and Energy
Riboflavin is crucial for releasing energy from the food you eat and plays a key role in maintaining healthy skin, eyes, and a well-functioning nervous system.
Excellent Food Sources of Riboflavin:
- Dairy Products: Milk and plain yogurt are significant sources of riboflavin.
- Eggs: A versatile and readily available source.
- Fortified Cereals: Many breakfast cereals are fortified with riboflavin.
- Mushrooms: A flavorful and nutritious source.
Important Note: Riboflavin can be destroyed by UV light, so store riboflavin-rich foods, especially dairy, away from direct sunlight.
Daily Riboflavin Needs:
- Men (19-64 years): 1.3mg per day
- Women (19-64 years): 1.1mg per day
A balanced diet typically provides enough riboflavin. Like thiamin, riboflavin is not stored in the body and needs to be replenished daily.
Riboflavin Supplementation:
Supplementation is generally not needed. While high doses haven’t shown significant harm, it’s best to focus on dietary intake.
Niacin (Vitamin B3): Energy, Nerves, and Healthy Skin
Niacin is vital for energy metabolism, keeping your nervous system in top shape, and maintaining healthy skin. It exists in two forms: nicotinic acid and nicotinamide, both found in food.
Top Food Sources of Niacin:
- Meat: Beef, pork, and poultry are good sources.
- Fish: Tuna, salmon, and other fish provide niacin.
- Wheat Flour: A common source in many diets.
- Eggs: Another readily available source.
Daily Niacin Needs:
- Men: 16.5mg per day
- Women: 13.2mg per day
Most people can meet their niacin needs through a balanced diet. Niacin is also not stored in the body.
Niacin Supplementation:
High doses of nicotinic acid supplements can cause skin flushing. Long-term high doses may lead to liver damage. Nicotinamide supplements have less evidence of adverse effects at high doses, but it’s still best to obtain niacin from food.
Pantothenic Acid (Vitamin B5): Energy and Hormone Helper
Pantothenic acid is a versatile vitamin involved in numerous bodily functions, most notably helping release energy from food and contributing to hormone production.
Abundant Food Sources of Pantothenic Acid:
Pantothenic acid is widespread in a vast array of foods, making deficiency rare.

Daily Pantothenic Acid Needs:
No specific daily amount is set in the UK due to its widespread availability in food.
Pantothenic Acid Supplementation:
Supplementation is generally unnecessary and high doses are not well-studied for adverse effects.
Vitamin B6 (Pyridoxine): Metabolism, Red Blood Cells, and More
Vitamin B6 is a multi-tasking vitamin involved in using and storing energy from protein and carbohydrates. It’s also crucial for forming hemoglobin, the oxygen-carrying component of red blood cells.
Diverse Food Sources of Vitamin B6:
- Meat: Pork and poultry are good sources.
- Fish: Some types of fish contain vitamin B6.
- Peanuts and Soybeans: Plant-based sources.
- Wheatgerm and Oats: Grain-based sources.
