The main dietary sources of vitamin A are liver, milk and diary products, butter, eggs and fish. In plants such as carrot, broccoli, spinach, pumpkin, vitamin is found as ß-carotene (the orange pigment). This vitamin easily dissolves in alcohol and vegetable oils while in water and glycerol not. Heat and UV light can reduce retinoid's (vitamin A) activity because of its decomposition under these factors.
Vitamin A dietary sources are natural path to health while Roaccutane acne treatment is the artificial enrichment of the organism with the purpose of treating acne. Taking the dietary shapes of vitamin A do not bring any overtaking hazard so it is theoretically better to receive it naturally instead of using Roaccutane. In practice this is not applied because of the intake amount control. Vitamin A accumulates in the liver and just 15g of beef of chicken liver contains required daily intake. Here's a list of food containing vitamin A and percentage of Recommended Dietary Allowances of vitamin A per 100g:
-carrot: more than 90%
-broccoli leafs: about 90% (unlike the broccoli, which has 3%)
-butter: 75%
-spinach: 50%
-pumpkin: 40%
-eggs: 15%
Vitamin A dietary sources like turnip leaves, kale, pea, endive, collard and dandelion greens are representatives of green plants containing vitamin A. The fruits and vegetables sources of vitamin A are: sweet potatoes, apricot, winter squash, cantaloupe melon, papaya and mango.

Side effects of Vitamin A
Roaccutane consumed in high doses has the equal side effect like vitamin A. Side effects of vitamin A such as skin cleansing are positive, while it can simultaneously cause serious damage to skin.
Roaccutane dries skin and therefore is susceptible to inflammation and redness. Skin becomes itchy and easily darkens on sunlight. Roaccutane or vitamine A side effect is related to impaired night vision, disease also known as night blindness. Experiments have proved that each entry of Accutane slows the recovery of rod vision signaling. Side effect varies from person to person and many Roaccutane users haven't experienced impaired vision. Extremely high amounts of vitamin A present in blood cause birth defects so Roaccutane strictly prohibited before and during the pregnancy. It needs up to one month to cleanse the body of vitamin A in blood and it's side effects. Vitamin A and ingredients derived from it have competency inside the brain so side effects of vitamin A could be linked to psychological impact during treatment.
Mostly known but not so common side effects of vitamin A, first signs of excessive dose are: redness (rosacea), headaches, itching and dry skin while in chronic case hair loss, insomnia, weight loss, liver damage, depression, fatigue and in some cases isotretinoin could affect on unborn child. Hypervitaminosis A is usually consequence of long-term treatment of disease (acne, psoriasis) with isotretinoin and for that reason Roaccutane therapy should always be under the supervision of doctor.

Vitamin A and Roaccutane dose
Recommended Dietary Allowances (RDA) for man are 900 µg and for woman 700 µg, during pregnancy the dose is slightly larger while in lactation stage is up to 1300 µg. The quantity can be also measured in international units (IU), used for the measurement of the amount of a substance. It is generally applied in biology for the measurement of vitamin dose allowances, hormones or blood products.
One thousand IU is the biological equivalent weight of 600 µg carotene or 300 µg retinol. RDA of vitamin A is 3000 IU beta-carotene or 1500 IU retinol. One Roaccutane capsule has about 5000 IU and the Roaccutane dose is prescribed towards to body weight. Typically, it's 0.5 mg of Roaccutane per kilo of body weight which is from 2 up to 5 capsules in one day. Pharmaceutical company that manufactures Roaccutane, Roche, states that it requires approximately 1 million IU retinol per day to acquire the toxic effect of more than 1 mg isotretinoin so almost 100 times lower dose is regarded as down borderline. 20,000 IU will definitely solve the most difficult cases and therefore there is no need for exaggeration. The effect would be immediately visible, even with the minimal dose.
Additional problems caused by the long-term intake arise after a period of one year, which nobody of Accutane users needed. Regardless of the security guarantee from the manufacturer, all products containing additional amount of vitamin A should be avoided. Taking too high vitamin A dose (hypervitaminosis) can result in many specific side effects such as changes and problems with the bones, skin and joints already caused by great Roaccutane dose.

Does vitamin A help acne?
Isotretinoin is an active ingredient contained in Roaccutane capsules utilized because of its useful properties. It's derived from vitamin A, nutrient present in in very small quantities but important for the health of human body. But does vitamin A help acne actually?
Vitamin A is found in food which contains carotene and it's responsible for keeping the skin healthy. Meanwhile, those doses aren't sufficient for any effect on acne so the additional amounts must be artificially acquired to impact the acne on skin. That's the reason why capsules of Roaccutane help in the acne treatment no matter how serious side effects could high doses of vitamine A cause.
Another most important function is participation in the maintenance of healthy eyes. Vitamin A action is usually consequence of attracting on specific receptors so it affects the synthesis of some proteins important for our body. It participates in the synthesis of rhodopsin, a pigment responsible for the perception of a light. Chemical process is impossible without vitamin so lack of vitamin A can cause impaired night vision.
On other side it can cause effects like dermatological problems, poor immune system, changes in the production of growth hormone and the formation of red blood cells. Roaccutane definitely does help acne. Vitamin A supplementations can be obtained in any drugstore for the very cheap price, but Accutane contains isotretinoin, which is only partially vitamin and causes different effects so none supplement can replace Roaccutane in acne healing process.

Side effects of Isotretinoin
Roaccutane (Isotretinoin INN) is a medication used for the acne treatment. Drug (Roaccutane) efficiency is very good but the problem are side effects of isotretinoin. Isotretinoin naturally takes the place of vitamine A by partly replacing it's active ingredients. More accurately, isotretinoin is a retinoid, orange viscous oil derived from vitamin A which is an essential nutrient in the human body found in a very small quantities. Vitamin A has an important role in skin health, immune system, bone development, gene transcription, embryonic development etc. Taking high doses of vitamin A leads to hypervitaminosis that results in side effects such as skin affects that heals severe acne. Isotretinoin can cause following side effects: dry lips, skin, nose and eyes, muscle and joints pain, hair thinning and loss, sun sensitivity, headaches, increased liver enzymes, depression and birth abnormalities if taken during the pregnancy.
Closely related medication with properties of vitamin A, isotretinoin or brand name Roaccutane, is a synthetical drug appointed as acne cure in a whole world during last 20 years. In final conclusion, Roaccutane is just vitamine A syntetic alternative. It has helped to heal severe acne with high efficiency and generally long-term reliability in more than 13 million cases.
Vitamin A or more specifically Roaccutane treatment lasts for a few months and it is typically accompanied by negative and exhausting side effects of isotretinoin. As the saying goes that every drug is also a poison, it's the case with Roaccutane too. Accutane is available for order on the Internet but always take medicine with doctor's medical supervision to prevent possible skin and organs damage. Medication taken by prescription is the safest way to personal health, don't risk dangerous body injuries. Doctor takes care about the intensity of Roaccutane (Isotretinoin) side effects like skin condition and blood tests, advises the increase and decrease of the prescribed dose and most importantly- experience that advice from the Internet cannot replace.
Many side effects of Isotretinoin are even more harmful, such as depression and the possible pregnancy side effects like birth abnormalities. They lead to the question: how much dangerous is Roaccuane actually? It is mentioned before that vitamin A is present in blood of every person and Accutane replaces natural ingredients. That's the reason why isotretinoin doesn't accumulate like poisons in the human body. The bloodstream rapidly gets rid of excess amounts of vitamin A (or in this case Roaccutane- Isotretinoin) in less than 2 weeks preventing permanent side effects of isotretinoin. Because of that fact and enormous benefit that the drug offers, Roaccutane is relatively safe medicament.
