Functional

  • Docosahexaenoic acid (DHA)

    Docosahexaenoic acid (DHA) is a long-chain polyunsaturated omega-3 (n-3) fatty acid considered to be nutritionally essential to maintain optimal health. There are a number of known health benefits associated with omega-3 fatty acid intake, with most current research focusing on the n-3 fatty acids DHA and EPA (eicosapentaenoic acid). In the body, DHA is an important component of cell membranes, particularly in the brain and retina. However, the human body cannot synthesize omega-3 fatty acids on its own, so these nutrients must be provided by the diet. By consuming the n-3 fatty acid alpha-linolenic acid (ALA) from sources such as flax seed, the body can convert ALA into EPA and eventually DHA, but the low rate of conversion supports direct dietary intake of DHA from foods and dietary supplements 1. The major food sources of DHA, as well as EPA, are algae and cold-water oily fish, such as salmon, herring, mackerel, anchovies and sardines 2. Dietary supplements containing significant amounts of EPA and DHA are typically fish oils derived from these fish. In addition, infant formulas often contain supplemental DHA. The U.S. Food and Drug Administration (FDA) has determined that the use of DHA and EPA omega-3 fatty acids as dietary supplements is safe, provided that the daily intakes of DHA and EPA do not exceed 2 grams per day from dietary supplement sources such as fish oil 3. A major safety concern is the possible presence of heavy metals and toxins, which can be found in relatively high levels in fresh fish and unpurified fish oils. When considering omega-3 DHA and EPA dietary supplements, it is important to look for fish oils that have been purified to reduce the levels of these contaminants.

Natural tocopherols exist as a mixture of d-alpha-, d-beta-, d-gamma- and d-delta-isoforms, each having antioxidant activities 1. Tocopherols are present in many foods, such as vegetable oils, nuts and grains. They are considered generally recognized as safe (GRAS) by the U.S. Food and Drug Administration (FDA) for use in foods (21CFR182.3890) 2.

  • Omega-3 fatty acids

    Omega-3 (n-3) fatty acids generally refer to the nutritionally essential polyunsaturated fatty acids (PUFAs) alpha-linolenic acid (ALA), eicosapentaenoic acid (EPA), and docosahexaenoic acid (DHA). Fatty acids are the building blocks of lipids, making them important sources of energy for the body and the main components of cell membranes 1. There are a number of known health benefits associated with omega-3 fatty acid intake, with most current research focusing on the longer chain n-3 PUFAs EPA and DHA. However, the human body cannot synthesize n-3 fatty acids on its own, and so these nutrients must be provided by the diet 1. Food sources of ALA include flax seed, hemp seed, walnut, canola, soy bean, and dark green leaves, while the major sources of EPA and DHA are algae and cold-water oily fish, such as salmon, herring, mackerel, anchovies and sardines 2.
      Dietary unsaturated fatty acids are well absorbed through the intestine and into the bloodstream. The Institute of Medicine has established an adequate intake of 1.6 g/day ALA for men and 1.1 g/day ALA for women 1. The body can form EPA and DHA from ALA, but the low rate of conversion supports direct dietary intake of EPA and DHA. The U.S. Food and Drug Administration (FDA) has determined that the use of EPA and DHA omega-3 fatty acids as dietary supplements is safe, provided that the daily intakes of EPA and DHA do not exceed 2 grams per day from dietary supplement sources such as fish oil 3. A major safety concern is the possible presence of heavy metals and toxins, which can be found in relatively high levels in fresh fish and unpurified fish oils. When considering omega-3 EPA and DHA dietary supplements, it is important to look for fish oils that have been purified to reduce the levels of these contaminants.

  • Vitamin D3

    Vitamin D is a fat-soluble vitamin that exists in two physiologically relevant forms, ergocalciferol (vitamin D2) and cholecalciferol (vitamin D3). Ergocalciferol is synthesized by plants and mushrooms, while cholecalciferol is synthesized by humans in the skin when it is exposed to ultraviolet-B (UVB) rays from sunlight. Some foods may also be fortified with vitamin D, such as milk and breakfast cereals. The current average daily intakes of vitamin D for Americans are well below suggested adequate intakes1, and much of the world’s population is deficient in this important vitamin 2.

    The main function of vitamin D is to regulate serum calcium and phosphorus concentrations within the normal range by enhancing the efficiency of the small intestine to absorb these minerals. By influencing the absorption of calcium, vitamin D helps to form and maintain strong bones and teeth 3,4.

    Vitamin D supplementation helps prevent falls and maintain physical performance in the elderly4,5. Adequate vitamin D intake may also be important for maintaining immune health6,7, nervous system health8, may help improve mood during the winter months9,10 and improve overall quality of life11.

    Vitamin D is generally well tolerated at recommended doses. The U.S. Food and Drug Administration (FDA) has established a Reference Daily Intake (RDI) of 400 international units (IUs) vitamin D for adults and children 4 or more years of age. RDIs are a set of dietary references for essential vitamins and minerals that are considered amounts sufficient to meet the daily requirements of healthy individuals. RDIs serve as the basis for calculating the percent daily value (% DV) amounts found on dietary supplement and food labels.

    According to the Endocrine Society’s Vitamin D Clinical Practice Guidelines, individuals who are at risk for vitamin D deficiencies should ask their physician to have their blood tested for the vitamin D metabolite [25(OH)D]. For individuals with blood 25(OH)D levels <75 nmol/L, higher amounts of vitamin D intake are suitable: children ages 1–18 may need 600–1,000 IU daily,adults >18 age may need 1,500–2,000 IU vitamin D daily12.

     Many Americans Would Benefit from Intake of Supplemental Vitamin D Higher than Current RDAs

Formulation

  • Kosher gelatin

    Kosher gelatin. Gelatin is a protein derived from animal collagen, usually from cow or pig skin and bones. In order for a food to be classified as kosher, the ingredients, preparation and processing facilities must all meet kosher standards. Gelatin is a commonly used gelling agent in foods and can also be used to form hard or soft gelatin capsules for oral products 1. Gelatin is approved for use as a food additive by the U.S. Food and Drug Administration (FDA) 2.

  • Natural lemon flavor

    Natural lemon flavor is oil extracted from the flavoring constituents of lemons, primarily the peels. Its significant function in food is flavoring rather than nutritional (21CFR501.22).

    This ingredient can also be found in the following products:

  • Purified fish oil concentrate

    Purified fish oil concentrate. Commercial fish oils marketed as dietary supplements are typically derived from fresh, cold-water, oily fish, such as salmon, herring, mackerel, anchovies and sardines 1. The use of fish oil supplements is intended to provide the body with the essential omega-3 fatty acids, EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid). Concentrated fish oils tend to contain higher amounts of EPA and DHA. While consuming fatty fish can also provide these omega-3 fatty acids, most individuals do not consume the required servings. In addition, much of the available fish today is raised on farms rather than in their native water habitats, greatly reducing their concentrations of EPA and DHA. Furthermore, cold-water fish can contain dangerous amounts of environmental pollutants, such as mercury, PCBs (polychlorinated biphenyls) and dioxins 2. A major safety concern is the possible presence of these polluntants, which can be found in relatively high levels in fresh fish and unpurified fish oils. When considering omega-3 EPA and DHA dietary supplements, it is important to look for fish oils that have been purified to reduce the levels of these contaminants. The most common molecular distillation and steam deodorization techniques use a combination of pressure and high temperatures to remove environmental pollutants from fish oil supplements so that they may pass global regulatory standards 3.

  • Omega-3 Fatty Acids Background
    • Most American diets provide more than ten times as much omega-6 than omega-3 fatty acids, even though there is general scientific agreement that individuals should consume more omega-3 and less omega-6 fatty acids to promote good health
    • Supplemental omega-3s can help reduce an imbalance in the ratio of omega-6 to omega-3 fatty acids often caused by the common Western diet
    • Omega-3s are called essential fatty acids because the body cannot synthesize omega-3s
    • Omega-3 fatty acids are nutrients essential to health and must be obtained through the diet*
    • Humans are dependent upon dietary intake of omega-3s to get an adequate amount, a necessity for good health in people of all ages*
    • EPA (eicosapentaenoic acid) and DHA (docosahexaenoic acid) are two omega-3 fatty acids that [are important to/contribute to] health*
    • In evaluating the beneficial effects of omega-3 fatty acids, researchers have focused on EPA and DHA
    • Alpha-linolenic acid (ALA), which is present in vegetable oils such as flaxseed and canola oils, is poorly converted to EPA and DHA in the body. Thus, direct dietary intake of these compounds is important.
    • Omega-3 fatty acids include ALA, EPA and DHA. ALA is present in vegetable oils such as flaxseed and canola oils, whereas EPA and DHA are found in algae and fish oils. ALA is chemically the parent compound but the body does not efficiently convert it to EPA and DHA. Thus, direct dietary intake of EPA and DHA is important.
    • Intake of omega-3 fatty acids has been identified as one of twelve modifiable behaviors (along with quitting smoking, lowering salt intake, etc.) that can contribute to increased longevity. A study showed that individuals with intake levels of 250 mg per day of EPA and DHA tended to live longer.*
    • There is continuing scientific debate as to whether or not dietary omega-3 fatty acids contribute to weight loss. However, higher blood levels of omega-3 fatty acids are associated with a healthier body weight.*
    • International experts suggest that individuals should aim to achieve an average daily intake of at least 650 mg of EPA and DHA combined, with at least 220 mg of each. The U.S. Institute of Medicine has not established an adequate intake level for omega-3 fatty acids but other countries, including Canada, Sweden, the UK, Australia and Japan, recommend intake of 300 to 500 mg per day of EPA and DHA.
    • International experts suggest that pregnant and lactating women should aim to achieve an average daily intake of at least 200 mg DHA. This amount is thought to be sufficient to help support optimal visual and cognitive development in the fetus and nursing infant.* Mannatech’s Omega-3 with Vitamin D3 supplies 450 mg DHA per day when taken as recommended.
  • Vitamin D Background
    • Research suggests that high vitamin D [intake/blood levels] can support breast and colorectal health*
    • An estimated 70 percent of the U.S. population has diets deficient in vitamin D
    • The typical American diet provides only about 30 percent of the recommended daily intake of vitamin D
    • A deficiency in vitamin D will reduce the amount of dietary calcium that is absorbed by 10-15 percent
    • Vitamin D deficiencies have reached epidemic status throughout the world
    • The following populations are at risk for vitamin D deficiency:
      • children and adults with dark skin pigmentation
      • those with a lack of exposure to sunlight
      • those who consistently wear a sunscreen with a protection factor of 30 or higher
      • older adults living in institutions without exposure to sunlight
      • pregnant and lactating women whose bodies must meet the demands of growing fetuses or infants
      • pregnant and lactating women
      • those over the age of 70, as vitamin D absorption may decline with age
      • those over the age of 70
      • obese children and adults (BMI > 30 kg/m2), as vitamin D is sequestered in body fat
      • obese children and adults
      • people taking the following medications: anti-convulsants, glucocorticoids, antifungals (e.g. ketoconazole) and drugs for AIDS/HIV
      • vegans, vegetarians and those who do not consume enough animal food products, such as milk, eggs, fish or meat, may be at risk for a deficiency in vitamin D
      • older adults with a history of falls
    • The major source of vitamin D is exposure to natural sunlight
    • Insufficient sunlight is a well-known risk factor for vitamin D deficiency
    • Human skin requires several minutes of regular and direct exposure to sunlight (UVB rays) in order to produce vitamin D3. Dark skin, sunblock use, and insufficient sun exposure (due to limited outdoor activity, seasonal/temporal/atmospheric factors, and geographic latitude) have all been associated with lower circulating hydroxyvitamin D levels
    • Very few foods naturally contain or are fortified with vitamin D
    • Vitamin D deficiency in the elderly increases the risk of bone fracture
    • The National Academy of Science’s Institute of Medicine (IOM), which sets the Daily Reference Intakes for the U.S., has set the Recommended Dietary Allowance (RDA) for vitamin D at 600 IU per day for all life stages with the exception of people over 70 years old for which the RDA is 800 IU per day. The IOM Committee found that vitamin D blood levels of 20 ng/ml 25 (OH)D are sufficient for bone health. Vitamin D deficiency was defined as serum levels below this amount.
    • An international group of vitamin D experts in The Endocrine Society challenged the IOM findings, suggesting that vitamin D insufficiency be defined as 25 (OH)D levels of 21-29 ng/ml and sufficiency as levels of 30-100 ng/ml (75-250 nmol/L).
    • The Endocrine Society suggested the Upper Limit (UL) be 10,000 IU for adults and 4,000 IU for children ages 1-18, rather than the 4,000 IU to 2,500 IU UL’s set for these age groups by the IOM.
    • The Endocrine Society Task Force finds that, although 400 to 600 IU/day vitamin D may be sufficient for children aged 0-1 year and 1 to 18 years, an amount of 1,000 IU/day may be required to raise blood levels of 25(OH)D above 30 ng/ml.
    • The Endocrine Society Task Force finds that, although adults 19-50 years require at least 600 IU/day, 1,500-2,000 IU vitamin D/day may be required to raise blood levels of 25(OH)D above 30 ng/ml.
  • Omega-3 Fatty Acid and Vitamin D Background
    • Omega-3 fatty acids and vitamin D are both required nutrients. There is significant evidence that much of the world’s population is deficient in both nutrients.
    • There are a limited number of foods that are naturally rich in vitamin D and/or omega-3 fatty acids. Fish is one such source, but given concerns that certain types of fish can be contaminated with ocean pollutants, especially mercury, it is advised to limit consumption of fish known to be lower in mercury, such as salmon, to only 2 servings (12 oz.) per week.
