Recommended Daily Allowances

An explanation of RDAs

Last Update 3 months ago

To maintain a healthy lifestyle, it's essential to understand the recommended daily levels and functions of key nutrients and health measurements suggested by research and medics. See references below the article for source evidence.


Please bear in mind that the 'allowances' are bare minimum requirements. For example, the vitamin C level, I understand is sufficient to avoid scurvy!


Here's a simplified guide:---


Daily Recommended Intake or Recommended Daily Allowance (RDI or RDA):


Magnesium

Men: 400–420 mg/day

Women: 310–320 mg/day 

Pregnant women: 350–400 mg/day


Role: 

Supports muscle and nerve function, bone health, and energy production. Found in nuts, seeds, whole grains, and leafy greens[1][5][12]


Vitamin C

Men: 90 mg/day

Women: 75 mg/day

Pregnant women: 85–120 mg/day


**Upper Limit**: 2,000 mg/day for adults is suggested, although when dealing with a serious illness or disease, considerably more is required. Worst case scenario the body eliminates excess through urination.


Intravenous vitamin C is particularly helpful when the immune system is compromised


Role: 

Boosts immunity, helps iron absorption, supports collagen production, and acts as an antioxidant. Found in citrus fruits, bell peppers, and broccoli[2][3][10].


Protein- General Guideline

Adults: ~0.8 grams per kilogram of body weight per day.


Role

Essential for muscle repair, enzyme production, and overall cell function. Sources include meat, fish, eggs, beans, and tofu - ideally all organic


Zinc- Daily Recommended Intake

Men: 11 mg/day

Women: 8 mg/day


Role: 

Supports immune function, wound healing, and DNA synthesis. Found in meat, shellfish, legumes, and seeds.


Calcium - Daily Recommended Intake


Adults: 1,000–1,200 mg/day.


Role:

Vital for strong bones and teeth and proper muscle function. Found in dairy products, fortified plant milks, and leafy greens.


Sodium

Recommended Limit**: - Less than 2,300 mg/day (about one teaspoon of salt) according to medics.

I prefer the Barbara O'Neill version - take a grain of celtic salt with every glass of water. Avoid processed and poisonous table salt - that's where the problem lies. Use Celtic, Sea or Hymalayan salt.


Role: Maintains fluid balance and supports nerve function but can raise blood pressure if consumed in excess according to medics.


Hydration

General guideline:  2–3 litres of good quality water daily for most adults. Adjust based on activity level, climate, and individual needs. NEVER drink direct from a domestic tap unless you have no choice. Always filter and remineralise drinking water for optimum uptake.


Role: Hydration plays a crucial role in maintaining overall health and proper bodily functions. Water is essential for life, and our bodies rely on it for numerous vital processes including waste removal, nutrition transportation, temperature regulation, brain function, digestion, detoxification, circulation, brain function, cellular balance, bone and organ protection.


Ketones

Ketones are produced when the body burns fat for energy instead of carbohydrates (e.g., during fasting or low-carb diets). Monitoring ketone levels is relevant for those on ketogenic diets or managing diabetes.


Oxidative Stress

Oxidative stress occurs when there’s an imbalance between free radicals and antioxidants in the body. Combat it by consuming antioxidant-rich foods like fruits (berries), vegetables (spinach), nuts, and green tea.


pH Balance

The body's pH is tightly regulated around a slightly alkaline level of  7.4. Whereas individual measurements for saliva and urine are different - 

A balanced diet rich in fruits and vegetables helps maintain balance.


By following these guidelines and maintaining a balanced diet with regular physical activity, you can support overall health effectively. Always consult a healthcare professional for personalised advice tailored to your specific needs.
