Calcium is essential for building and maintaining strong bones and teeth. It also supports muscle function, nerve signaling, and blood clotting. Adequate calcium intake can help prevent osteoporosis and maintain overall bone health. You can find calcium in dairy products, leafy greens, fortified foods, and certain fish. For more details, you can explore the  National Institutes of Health

Many adults today do not meet their recommended calcium intake. Studies indicate that calcium is considered a "nutrient of public health concern" due to widespread underconsumption, particularly among women and older adults  (Source: NIH) ). This deficiency can lead to health issues like osteoporosis and weakened bone health over time.

The "best" source of calcium depends on your dietary preferences, tolerances, and needs. Here's a breakdown:

• Dairy products (milk, yogurt, cheese) : These are highly calcium-dense and easily absorbed by the body, making them ideal if you're not lactose intolerant.
• Fortified foods (orange juice, plant-based milk) : Great options for those who avoid dairy, as they offer high calcium content and good bioavailability.
• Sardines and salmon with bones : Excellent for those who enjoy seafood and want to benefit from additional nutrients like omega-3s.
• Leafy greens (kale, collard greens) : A plant-based option, though the calcium absorption may be slightly lower due to compounds like oxalates.

For most people, dairy and fortified foods are the most efficient sources. However, combining several options can ensure variety and meet your calcium needs. 

Calcium absorption varies depending on the source:

• Dairy Products : About 30–35% of calcium from milk, cheese, and yogurt is absorbed. These are highly bioavailable sources.
• Fortified Foods : Calcium from fortified orange juice and plant-based milks is absorbed at a similar rate to dairy, around 30–35%.
• Fish with Bones : Calcium from canned sardines and salmon is well absorbed, with rates comparable to dairy (around 30–35%).

With ROI WATER about 50% of the calcium value is absorbed  because the minerals in  natural ionic form . It helps stabilize mood and supports neurotransmitter function, reducing stress-related tension.

Potassium is vital for maintaining fluid balance, supporting muscle contractions (including the heart), and transmitting nerve signals. A potassium-rich diet can help lower blood pressure, reduce the risk of stroke, and prevent kidney stones. Foods like bananas, oranges, potatoes, and spinach are excellent sources. For more details, you can explore the  National Institutes of Health

Many adults today do not meet the recommended potassium intake. Globally, the average potassium consumption is around  0.08 oz/day  (2.25g/day) which is below the World Health Organization's guideline of  0.123oz /day (3.5g/day)  . Low potassium intake is often linked to diets high in processed foods and low in fruits and vegetables. This deficiency can increase the risk of high blood pressure, kidney stones, and cardiovascular issues. (Source: NIH)

To meet the daily potassium intake guideline of  3,400 mg for men  and  2,600 mg for women , here's an approximate idea of how much you might need to consume:

• Bananas : About 7 medium bananas (0.450 mg each).
• Spinach (cooked) : Around 3 cups (0.839 mg per cup).
• Sweet Potatoes (baked with skin) : About 5 medium sweet potatoes (0.542 mg each).
• Milk : Roughly 4 cups (0.366 mg per cup).
• Salmon : Around 6 ounces (1,068 mg per 6 oz fillet).

The body absorbs about  90% of the potassium  from dietary sources, which is a high absorption rate compared to other  minerals.  This efficient absorption occurs primarily in the small intestine through passive diffusion. Factors like overall diet, health conditions, and potassium-sodium balance can influence how well the body utilizes potassium. (Source: NIH)

With ROI WATER you  receive  high mineral  absorption and  high potassium  absorption in one. You don’t need to eat 7 bananas per day. 

Bicarbonate plays a key role in maintaining the body's pH balance, helping to neutralize excess acid. It supports digestive health, reduces acid reflux, and may enhance physical performance by buffering lactic acid during exercise. For more details, you can explore the  National Library of Medicine .

Maintaining pH balance is essential for overall health, even in today's modern lifestyle. The body naturally regulates its pH levels to ensure optimal functioning of processes like digestion, metabolism, and oxygen transport. However, factors like stress, poor diet (high in processed foods), and lack of hydration can disrupt this balance, potentially leading to issues like fatigue, weakened immunity, and bone demineralization.

An unbalanced pH in the body can lead to various health risks depending on whether the imbalance is toward acidity ( acidosis ) or alkalinity ( alkalosis ):

Acidosis (Excess Acidity)

• Fatigue and Weakness : Low pH can impair energy production.
• Bone Health Issues : Chronic acidity may lead to calcium loss from bones, increasing the risk of osteoporosis.
• Kidney Stress : High acidity can overwork the kidneys, potentially leading to kidney stones or chronic kidney disease.
• Increased Risk of Gout : Excess acid promotes uric acid buildup, causing gout attacks.
• Digestive Problems : Acid reflux and heartburn are common symptoms.

Alkalosis (Excess Alkalinity)

• Muscle Cramps and Weakness : Caused by disrupted electrolyte balance, particularly calcium and potassium.
• Nervous System Issues : Symptoms like confusion, dizziness, or tingling sensations.
• Respiratory Problems : Shallow breathing or difficulty breathing in severe cases.

To maintain a healthy pH balance, focus on incorporating  alkaline-promoting foods  into your diet. Here's a list of foods and approximate daily intake values to support pH balance:

Alkaline-Promoting Foods

• Leafy Greens (Spinach, Kale): About 200–300 mg of calcium per 2–3 cups.
• Fruits (Bananas, Avocados): Bananas provide around 422 mg of potassium per medium banana; avocados contain about 485 mg of potassium per half.
• Vegetables (Broccoli, Sweet Potatoes): Broccoli has 288 mg of potassium per cup; sweet potatoes with skin offer about 542 mg of potassium per medium.
• Legumes (Lentils, Chickpeas): Lentils provide 731 mg of potassium per cup, while chickpeas offer about 474 mg per cup.
• Nuts and Seeds (Almonds, Chia Seeds): Almonds contain around 76 mg of magnesium per ounce; chia seeds have 95 mg of calcium per ounce.
• Herbal Tea (Chamomile, Ginger): Small amounts of minerals per cup, supporting hydration and alkalinity.
