W7-L4: Vitamin E & Vitamin K Flashcards
What are the functions of Vitamin E?
4
- Antioxidant Protection
- Immune Response
- Cell Signalling
- Platelet Adhesion Modulation
How does Vitamin E aid in
Antioxidant Protection?
Prevents oxidative damage to cell membranes, mainly due
to its ability to neutralize free radicals.
Vitamin E is especially important in protecting polyunsaturated fats in cell membranes from lipid peroxidation, which could otherwise lead to cell damage or death.
How does Vitamin E aid in
Enhancing the Immune Response?
Enhances immune response, helping the body fight off infections and supporting immune cell function (T-cells and B-cells).
How does Vitamin E aid in
Cell Signaling?
helps regulate key biological processes like cell growth, differentiation, and apoptosis (programmed cell death).
Vitamin E helps maintain cell communication, ensuring proper cellular function and maintaining tissue health.
How does Vitamin E aid in
Platelet Adhesion Modulation?
reducing the risk of excessive blood clotting
What is the RDA for Vitamin E?
15mg (M & F)
What is the UL for Vitamin E?
Up to 1,000mg/d tolerated but not recommended
What might lead to a deficiency in Vitamin E?
Deficiency is rare unless there are issues absorbing fats from food e.g. celiac disease
What can Vitamin E toxicity lead to?
rare, can cause excessive bleeding
What population should be
cautious w/ Vitamin E?
Caution: clients taking blood tinners
What are the 2 Types of Vitamin K?
K1 & K2
What is the Function of Vitamin K1?
Where is it obtained?
- Primary role: Blood clotting
- Found in in leafy green vegetables; converted to vitamin K2 by bacteria
What is the Function of Vitamin K2?
Where is it obtained?
- Primary role: Bone health, kidney health, Heart and cardiovascular health – mostly in it’s regulation of calcium
- Found in animal livers and some fermented foods
What is the RDA for Vitamin K?
Men 120 mcg , Women 90 mcg
No UL established
What can Vitamin K deficiency lead to?
- bleeding and hemorrhage
- decreased bone mineralization and osteoporosis
What can Vitamin K toxicity lead to?
Toxicity – unknown in adults
But Vitamin K can interfere with warfarin (anticoagulant) and some antibiotics so supplementation should be discussed with medical team
What is the role of Vitamins in Exercise?
- Important for oxygen transport, immune system, bone density, quenching excess free radicals
- Exercise stresses many vitamin dependent pathways but no clear rational that all exercising individuals need to supplement
- May be recommended to with those working with a professional to reducing calorie intake or to temporarily supplement a poor quality diet
