Growth and height of the human depend on some factors that we try to talk about the most important items:

1/Genetic: When both of the parents are tall so we expect that children will be tall (If other factors get ready).

2/Hormonal factors: One of the most important factors in the growth is the HUMAN GROWTH HORMONE (HGH).

-Some factors affect the production of HGH:

A/ Loose body fat.

B/ Sugar intake: High insulin level decrease the level of HGH so Diabetic patients have shorter height. The insulin level decrease 2-3 hours after eating so we can understand that fasting increase the level of HGH.

-For increasing the level of HGH by fasting we suggest intermittent fasting (Limit your eating to 500-600 calories 2 days per week).

C/High intensity exercise rise the level of HGH.

D/Adequate and deep sleeping increase the level of HGH so some supplements that improve our sleep such as, Melatonin and GABA are effective in release of HGH.

E/ High doses of Argenine boost release of HGH.

F/ Taking of Alanine before workout increases the number of repetitions and with this mechanism help to the release of HGH.

3/ Nutritional factors: For the bone formation and growth some vitamins and supplements are essentials:

-Calcium is the essential factor in the bone formation and in the absence of calcium no growth occurs.

-Vitamin D: For absorption of calcium from kidneys and gastrointestinal tract we need Vitamin D. In Canada everybody in the Fall and Winter need to supplementary vitamin D.

-The body growth highly depends on Iron and Zinc.

Coenzyme Q 10 also known Co Q10 or Ubiquinone is a natural antioxidant and has a big role in 1/ Energy production.2/ Prophylactic role in Migraine headache( it should be used at least for 3 months).3/ Support cardiovascular health.

Coenzyme Q 10 deficiency occurs due to:
Ageing, the amount of Co Q10  decrease with ageing.
Some drugs such as Propranolol or Statins decrease the amount of Co Q10.
So Co Q10 has two big roles in our body, First, Energy production Second, Antioxidant effects.

• Vitamin D is a fat-soluble vitamin that is necessary for the formation and preservation of bones,  vitamin D is important in the absorption of calcium from intestine and kidneys.
• Vitamin D intake is not a good indicator for body vitamin D level because the absorption of this vitamin is affected by other states such as stomach problems.
• Vitamin D can be made in the skin and some factors can affect vitamin synthesis such as using large quantities of sunscreen, being indoor too much, and living at high altitude.
• Vitamin D deficiency causes some problems such as

Osteoporosis

Muscle weakness

Mood disturbances such as anxiety or depression

Chronic pain

Hypertension

• There are some strategies for increasing vitamin D levels in the body.

1. Eat foods with adequate vitamin D such as seafood or fish liver oils, cheese has a small amount of vitamin D
2. Exposure to sunlight
3. Vitamin D supplements: For most adults, 600IU is enough but for children and postmenopausal women 800IU is enough

• For prevention of vitamin D deficiency, we suggest sunlight exposure, drinking milk that is fortified by vitamin D and using vitamin D supplements especially for breastfed infants
• In Canada, all people should take vitamin D in the fall and winter
