Vitamin D3 (cholecalciferol) is the active form of vitamin D
Deficiency of Vitamin D has significant medical and psychological consequences. Every tissue in the body has vitamin D receptors, including the brain, heart, muscles, and immune system, which means vitamin D is needed at every level for the body to function.
According to Toronto-based family medicine practitioner Dr. Sheila Wijayasinghe, nutritional deficiencies are one of the four main causes of nail problems like peeling or cracking. Vitamin D3 itself appear to play a role in maintaining nail integrity, the nutrient is necessary for proper calcium absorption and to regulate the concentration of the mineral in your blood. Calcium is also required for nail health; peeling nails may indicate that low vitamin D is affecting your calcium level.
Vitamin D is indispensable to the health, beauty, and longevity of the largest organ in the body: your skin. If adequate amounts of vitamin D are not available, your epidermal cells won’t form a watertight barrier that locks in moisture and keeps your skin soft and supple. As a result, the outer layer of your skin may become thinner and more fragile. It begins to sag from lack of adequate support. Dryness and wrinkles set in as moisture is gradually lost to the outside.
In addition to its well-known role in calcium absorption, vitamin D activates genes that regulate the immune system and release neurotransmitters (e.g., dopamine, serotonin) that affect brain function and development. Researchers have found vitamin D receptors on a handful of cells located in regions in the brain-the same regions that are linked with depression.
Seasonal Affective Disorder (SAD), a mood disorder featuring depressive symptoms, occurs during the dark times of the year when there is relatively little sunshine, coinciding with the sudden drop in vitamin D levels in the body. Several studies have suggested that the symptoms of SAD may be due to changing levels of vitamin D3, which may affect serotonin levels in the brain.
Vitamin B5 (pantothenic acid) Hydrator and Wound Healing
B5 is a humectant--a water-binding substance that attracts and retains water,
protecting the skin from the elements such as washing hands frequently.
Vitamin B5 has natural broad abilities to moisturize, soothe, heal and regenerate the skin. It stabilizes the skin barrier function, reducing the amount of water lost through the skin. By applying a B5 formulation to the skin, you will not only increase its hydration but improve its softness and elasticity, and is ideal for the treatment of redness, dry, scaly, itchy, or rough skin.
Additionally, a 2002 "Journal of Dermatological Treatment" study noted that Vitamin B5 enhanced the repair of the skin barrier while reducing inflammation. It’s effectiveness in hydrating, soothing, healing and protecting skin makes it an effective ingredient for: acne, bed sores, minor cuts, diaper rash, contact dermatitis (produced when the skin comes in contact with irritants or allergens), eczema, insect bites, scrapes and sunburn.
Preliminary research suggests that vitamin B5 has moisturizing effects on the skin and may speed wound healing, especially following surgery.
Biotin - Vitamin B7
"The Anxiety & Phobia Workbook," psychologist Edmund J. Bourne states that deficiencies of the B vitamins, including biotin, can lead to increased feelings of anxiety, irritability and emotional instability. In fact, a literature review published in the January/February 2007 issue of the "Journal of International Medical Research," points out the importance of all of the B vitamins for cognitive performance, especially if you have a stressful lifestyle, are elderly or experience occupational pressure.
In a small controlled study among women with brittle nail, showed supplementing with Biotin (vitamin B7) may increased nail thickness by 25% and reduced the tendency of nails to split (Columbo, J Am Acad Dermatol 1990).
Vitamin E is an antioxidant that protects and repairs your skin.
Apricot Oil is rich in is rich in omega – 9 ( oleic acid ) fatty acid, omega – 6 ( linoleic acid ), and Vitamin E which is why the oil is a powerful emollient. The oil’s fine texture allows more rapid skin penetration, which promotes more prompt healing and nourishment of sore or chapped skin without residue. Shirley Price, coauthor of “Aromatherapy for Health Professionals,” notes that apricot oil is also beneficial in relieving the itch and irritation of eczema-ridden skin as well as helps prevent and minimize the appearance of wrinkles.
Shea butter is rich in Vitamins A and E which are recognized as the
essential vitamins for skin care. These antioxidants heal and prevent cell
damage caused by toxic substances called free radicals. Vitamin A maintains the
firmness and elasticity of the skin while Vitamin E is mainly moisturizing. In
addition, Shea butter contains cinnamic acid that provides sun protection and
heals skin inflammation.
Vitamin B6 (Pyridoxine) helps your body make serotonin, a chemical that influences mood. Low levels of serotonin are associated with depression. Research has shown that vitamin B6 has a significant impact on the central production of both serotonin and GABA neurotransmitters in the brain. These are important hormones that control mood and are needed to prevent depression, pain, fatigue and anxiety. (20)
Researchers believe that certain behavior disorders in children, including ADHD, are caused by low serotonin levels and, therefore, that taking vitamin B6 might have a beneficial effect on children with a these learning and behavior disorders. (19)
