Vitamin A
is good for your vision

How does Vitamin A work?

Vitamin A, also known as retinol, is a fat soluble vitamin, important, for example, for good vision. Vitamin A is also important for the skin, gums and hair and plays an important role in growth and boosts the body’s natural defences.

In order for the body to better assimilate vitamin A, fatty substances, often found in conjunction with vitamin D and E, are essential. For pregnant women vitamin A is especially important. Vitamin A is contained in extremely high amounts in the liver (and products containing it). In pregnancy it is advised not to consume food with high levels of this vitamin.

Vitamin A in the diet

Vitamin A is found naturally in animal products such as meat, dairy products, eggs and fish. The liver contains a very high amount of vitamin A. In products such as margarine and cooking fats vitamin A is often added artificially.

The body is able to synthesize vitamin A thanks to betacarotene (also called provitamin A). Betacarotene is found mainly in green leafy vegetables and carrots. Vitamin A deficiency is rare – you would have had to abstain from eating a wide variety of foods over a long period for such a deficiency to occur. However, if confronted with a lack of vitamin A, the symptoms would include lower resistance to illness and poor skin health.

Excess Vitamin A

Prolonged intake greater than 3 milligrams per day of vitamin A, either through diet or through supplements, can be harmful. Possible disorders include loss of appetite, impaired vision, headache, nausea, visual disturbances, muscle aches, dizziness, redness and / or peeling of the skin.

Following the placement of a gastric band or sleeve

If you have recently undergone the placement of a gastric band or sleeve, it is important to take a lot of vitamin A, say between 1.2 and 1.5 micrograms per day. This value corresponds to 150-200% of the Recommended Daily Intake.

Following gastric bypass surgery, duodenal switch or biliopancreatic diversion procedures

If you undergo gastric bypass surgery or a duodenal switch procedure, in addition to a reduction in stomach size, the small intestine is also altered. Vitamin A is absorbed within the section that has been altered through surgery. The Recommended Daily Allowance or RDA requirement is between 150 to 200%, or from 1.2 to 1.5 micrograms of vitamin A per day for people who have undergone this kind of surgery.

Since an overdose of vitamin A can be harmful to your health, the daily dose contained in our WLS Optimum and WLS Forte supplements is slightly lower than the RDA and is equal to 1 milligram.

Vitamin A supplements

WLS Optimum and WLS Forte supplements offer you the adequate amount of vitamin A by taking just one capsule per day. For more information, please refer to our homepage: www.fitforme.co.uk
