Lewis Labs RDA® is a high quality nutritional supplement that provides 100% of the recommended daily requirement of essential nutrients, including 19 vitamins / minerals and 18 amino acids. Most important, it has an ideal balance of the 8 amino acids recognized as essential for human nutrition in each serving from protein.
With lutein extract, calcium and isoflavones, Lewis Labs® RDA is one of the best ways to meet your daily vitamin and mineral needs. No matter what your nutritional requirements, Lewis Labs RDA® is an ideal daily supplement for all adults in a good-tasting, easy to mix powder.
In nutrition, there is no such thing as a panacea. Taking individual vitamins or other nutrients that you believe may be lacking from your diet is seldom, if ever, the best approach to a nutrition problem. Very often, low levels of vitamins and minerals, if properly combined to interact with one another for maximum synergistic effect, may be all that one needs. An overall balanced nutritional intake that includes all of the essential vitamins, minerals, amino acids and key micro-nutrients is the essential first step.
No vitamin, mineral or protein works alone. They require the right combination of factors to make them work synergistically. For example, one of the essential amino acids, methionine, cannot be metabolized when Vitamin B6 is deficient; protein is not utilized in the absence of Vitamin A; Vitamin A cannot be absorbed without unsaturated fat; a zinc deficiency inhibits the release of Vitamin A stored in the liver; calcium cannot be absorbed without Vitamin D and on and on. As you can see, virtually all of the nutrients essential to our good health require the presence of other nutrients for maximum benefit.
The importance of a complete nutritional base, such as that provided by Lewis Labs RDA®, can be seen by looking at one nutritional element – calcium. While the same point can be made about any other single nutrient, we have selected calcium because it is an almost universally deficient element and is particularly difficult to supplement in amounts that are adequate.
Typically, the average person does not absorb calcium very well from food – perhaps no more than 10% - 20% of the calcium contained in the foods that are consumed. There are many reasons why this is so. For instance, a meal high in fats can form insoluble calcium soaps causing the calcium to pass through the system unabsorbed. Even the calcium in certain vegetables may be inhibited from absorption by oxalates found naturally in foods such as rhubarb, kale, spinach and broccoli or phytates found in grains and cereals. Vitamins A and D are essential for the absorption and use of calcium. That is why milk and practically all calcium supplements are fortified with these two vitamins. In addition, calcium requires an acid environment for absorption – a particular problem for older people who tend to have a lower production of digestive acids.
There is more. The amino acids leucine, arginine and serine are needed for the formation of calcium and amino acid complexes. Magnesium and phosphorus must also be present in an appropriate ratio. With these and other factors, you may lose a lot of the benefit of the calcium you are ingesting.
There is no flashing red light to warn you of a calcium deficiency. In fact, it is usually not detectable until irreversible damage has already been done. Even in extreme cases, the calcium level in the blood may appear to be normal. Why? The body has a calcium bank in our teeth and bones. In a calcium deficiency, a series of bio-chemical reactions are triggered and a check is written on your calcium bank as the need for calcium to control muscular contractions (including the heart), blood clotting, transmission of nerve impulses and other requirements, takes priority. In short, your teeth and bones are robbed to supply the needs elsewhere in your body.
The typical American diet supplies a meager 450 - 550 milligrams of calcium per day. This is far short of the 1000 milligrams recommended by the current RDI. Most nutritional experts now believe 1000 - 1500 milligrams is closer to what is needed on a daily basis. Yet, even if you adjust your diet to take in enough calcium, the probability is that most will pass through your body unabsorbed.
While each daily portion of Lewis Labs RDA® contains 100% of the daily calcium requirement, it also contains all of the other factors associated with the efficient utilization of calcium. It is a complete nutritional food that naturally stimulates the digestive acids to overcome the antacid of calcium carbonate.
Most nutritional authorities agree that proper supplementation to a prudent diet is the best protection against most of today's common killers, as well as being the key to a happier and more vibrant life. No matter what your needs may be, Lewis Labs RDA® is the proper cornerstone for a sound nutritional program. It is a complete supplement – ideal for the entire family and suitable for vegetarians.
To make sure you are getting everything you need, we recommend daily use of Lewis Labs RDA®. It is a very pleasant-tasting powder that mixes well with water, juice, milk or whatever liquid you prefer. Most important, however, is that 30g (three level tablespoons) per day will provide you with 100% or more of the recommended daily intake of all vitamins, minerals and essential amino acids (proteins). It is also a treasure trove of trace metals and minerals, so essential to act as catalysts in the metabolic process.
