The facts

Can you really be low in Vitamin D?

What are the statistics?

Are you getting enough Vitamin D?

Page 7: What is vitamin D?

Can you really be low?

•Too much sun can cause skin cancer

•Sun is also the main source of bone-building vitamin D

•High percentage of vitamin D deficiency in Australia and New Zealand

Page 8: What is vitamin D?

The estimates…

% of people low in Vitamin D

Males Females

Summer-autumn 27% 40 %

Winter-spring 35% 58%

•Professor Rebecca Mason estimates that in Australasia:

Adult Nutritional Survey in NZ: 32% of NZ population are below the recommended blood level of Vitamin D

Page 9: What is vitamin D?

Are you getting enough D?

•There are very few symptoms of D deficiency:o General aches and pains o Low resistance to infections including colds and flu

•Ask your doctor for a vitamin D test to find out

Page 10: What is vitamin D?

Who is most likely D deficient?

• Higher targets for optimum health

• More people in higher risk groups:Don’t go out in the sun much Older people Naturally dark skin Covered up with clothing Clinically obese People working indoors Entertained indoors

How much Vitamin D do we need?

Boys and girls 1-18yrs 15 μg (micrograms) day (600) (IU/day)

Adults (male and female) 19-70yrs 15 μg (micrograms) day(600) (IU/day)

Adults (male and female) 71+yrs 20 μg (micrograms) day (800) (IU/day)

50 nmol/L 50 nanomoles per litre of plasma is recommended

Note: Upper limit is 100 μg (micrograms) day (4000 IU/day) and adverse events can be seen above this level

These revised US Recommended Daily Allowances (RDA) for vitamin D are based on the amounts of vitamin D needed to maintain serum levels >50 nmol/L of blood with minimal exposure to sunlight.

How do I get vitamin D?

Safe Sun

Food

Supplements

Page 13: What is vitamin D?

Vitamin D from Safe Sun

• Sun is our major natural source of vitamin D

• Sun exposure of six to eight minutes in peak UV periods everyday should help to meet the average person’s requirements

Page 14: What is vitamin D?

Vitamin D from Food

Primarily from fortified foods including:

• Oily fish (salmon, sardines and swordfish)

• Vitamin D fortified foods (breakfast cereals, milk, butter, eggs, meat, etc.)

• UV-exposed mushrooms

Page 15: What is vitamin D?

Vitamin D from Supplements

• Helps bridge the nutritional gap

• Assumes prime importance for those at risk of deficiency

• Benefits those with sun-sensitive skin

• Support for the immunosuppressed

Page 16: What is vitamin D?

Supplementing with USANA Nutritionals

• USANA was one of the first global producers to act on emerging scientific evidence on vitamin D and raised the vitamin D

• Included in the EssentialsTM range

• USANA’s Vitamin D supplement for the vitamin D deficient

Page 17: What is vitamin D?

USANA’s Essentials

EssentialsTM - Mega Antioxidant – vitamin D increased from 150IU to 200IU per tablet

BodyRoxTM – vitamin D increased from 133IU to 333IU per tablet

Page 20: What is vitamin D?

USANA’s Vitamin D

Professor Mason commented on USANA’s vitamin D preparation saying

‘Vitamin D3 supplements as cholecalciferol provide the same form of vitamin D as we make in the skin and supplements are a reasonable way to improve vitamin D status if more sun exposure is not practical (if you do too much indoors, if you have dark skin, if it is culturally inappropriate and for older people who don’t want to go out or can’t do so).’ USANA Vitamin D; each tablet contains vitamin D3 (cholecalciferol) 1000 IU/25 micrograms. Suggested dose: take one table daily preferably with meals. Vitamin supplements should not replace a balanced diet. USE ONLY AS DIRECTED. ALWAYS READ THE LABEL.
