AGS Provider GeneED Training: Micronutrients
MicronutrientsTraining Objectives:
• Define micronutrients: vitamins and minerals.
• Describe how genetics can impact micronutrient needs through potential genetic predispositions revealed in the AGS Health & Wellness Genetic Test.
• Describe what happens if a predisposition becomes a deficiency.
• Describe the genes AGS uses and what specific effects they have on the human body and overall health and wellness.

• Micronutrients are chemical elements required in small quantities for healthy living.
• Micronutrients include:- Vitamins: organic compounds essential
for life (most cannot be synthesized by the body).
- Minerals: elements that originate from the Earth’s soil; also essential for life.
• The human body can only synthesize some vitamins (i.e. vitamin D with sunlight exposure), but not all. Additional nutrients must come from the foods we consume or through vitamin supplementation.

Micronutrients = Vitamins and Minerals
Proprietary & Confidential
• Genetics alone can reveal predispositions, not outright deficiencies. In order to determine full deficiencies, blood work or thorough physical examination by a physician is required.
• People with genetic predispositions have a greater likelihood of developing micronutrient deficiencies if they do not achieve proper nutrition through the foods they consume.
• Many predispositions can be countered through proper diet, but some individuals may require, or even prefer, supplementation:
- Very busy or active individuals.- Those who travel frequently.- Those who want to close nutritional gaps.

What Can Genetics Tell Us About Micronutrients?
Proprietary & Confidential
• Vitamin A: Required to maintain healthy skin, a strong immune system, good vision, and achieve adequate growth.
• Vitamin B6: Required for carbohydrate and protein metabolism. Supports blood cell synthesis and neurotransmitter synthesis.
• Vitamin B9 (Folate): Required for DNA synthesis, cell division, amino acid metabolism, and the maturation of cells (including red blood cells).
• Vitamin B12: Required to assist in the metabolism of folate (also necessary to make red blood cells).

What Micronutrients Does AGS Cover?
Proprietary & Confidential
• There are minimum requirements and “upper limits” (UL) for micronutrients.
• The minimum can be defined as the “Recommended Daily Amount (RDA)”:
- Vitamin A:• RDA: 0.6 - 0.7 mg/day• UL: 1.5 mg/day
- Vitamin B6:• RDA: 1.2 - 1.4 mg/day• UL: 200 mg/day

Can Supplements Interact with Medications?• Yes. Supplements can have profound physiological effects – interacting with each other, as
well as medications.
• Here are a few major interactions to be aware of:
- Vitamin A:• Be cautious with retinoid-containing medications to avoid excess vitamin A.• Can interact with Tetracycline and induce intracranial hypertension.• Can increase risk of liver damage if consumed with hepatotoxic medications.• Large amounts of Vitamin A may interfere with the medication Warfarin.
- Vitamin B6 • Taking Vitamin B6 with Cordarone may increase risk of sunburn.• May increase the breakdown of seizure medications such as Luminal and Phenytoin.• Moderate dosages of B6 are safe for most people, but very high dosages may be
problematic, especially if taken long-term.
Proprietary & Confidential
- Folate:• Can interfere with the antibiotics Tetracycline, Trimethoprim, and Sulfamethoxazole
(if taking both orally, separate time of consumption by at least 2 hours).• Large-dose supplementation of the following could result in decreased efficacy:
Fosphenytoin, Methotrexate, Phenobarbitol, Phenytoin, Primidone, Pyrimethamine.
- Vitamin B12:• May experience decreased efficacy with long-term usage of Chloramphenicol.
- Vitamin D:• Dosages exceeding UL could cause excessive blood-calcium, especially long-term
(may impact calcium-related processes in the body).• May lower the effectiveness of antihypertensive and cholesterol medications.• May impact aluminum and calcium based medications (i.e. antacids).• May increase the effect of medications such as Calcipotriene (synthetic vitamin D).• May impact calcium-channel blockers and heart medications.

Can Supplements Interact with Medications?
Proprietary & Confidential
- Vitamin E: (*Reported on the Premium Health & Wellness Genetic Profile only.)• Vitamin E can increase absorption and side-effects of Cyclosporine (can increase the
production of certain liver enzymes, impacting the medication’s effects).• Ask your doctor if on any medications processed by the CYP3A4 gene.• Vitamin E may slow blood clotting and increase the effects of anticoagulants.• May lower the effectiveness of statins (cholesterol lowering medications).• Taking Vitamin E along with beta-carotene, Vitamin C, and selenium may decrease
beneficial effects of niacin on cholesterol.• If taken with Warfarin, Vitamin E may increase bruising and bleeding.
- Iron: (*Reported on the Premium Health & Wellness Genetic Profile only.)• May decrease the effectiveness of antibiotics such as Quinolone and Tetracycline.• May decrease the effectiveness of the following medications: Levothyroxine,
Levodopa, Methyldopa, Mycophenolate Mofetil, Penicillamine.
AGS Provider GeneED Training: Micronutrients
Can Supplements Interact with Medications?
Important Tip to Avoid Supplement and Medication Interactions:Reduce supplement interactions with oral medications by separating time of consumption by 2+ hours.

Potential Side Effects from Inadequate Vitamin Levels

The Genetics of Micronutrients• Vitamin A:
- Gene BCMO1 (SNPs = rs12934922 and rs7501331)- Encodes a key enzyme for converting precursor beta-carotene to vitamin A.- *Note: Two variants which interact to affect vitamin A production.
• Vitamin B6:- Gene NBPF3 (SNP = rs4654748)- While still not fully understood, this gene is associated with decreased levels of vitamin B6.
• Vitamin B9 (Folate):- Gene MTHFR (SNP = rs1801133 [largest effect] and rs1801131)- Encodes an enzyme that methylates Folate for use in converting homocysteine (potentially
toxic) to methionine, an important amino acid and methyl donor.
• Vitamin B12:- Gene FUT2 (SNP = rs602662) - Associated with Vitamin B12 levels, possibly by affecting the microbiome.

AGS Provider GeneED Training: Micronutrients
The Genetics of Micronutrients• Vitamin D:
- Near Gene CYP2R1 (SNP = rs10741657): Controls key Vitamin D metabolism step in the liver.- Near Gene DHCR7 (SNP = rs12785878): Associated with Vit D levels in 34,000 person study.- Gene GC (SNP = rs2282679): Encodes Vitamin D binding protein that helps transport Vitamin
D to target tissues.
• Vitamin E:- Intergenic (SNP = rs12272004)- Variation is not embedded in a particular gene, but may affect a regulatory region or simply
be meaningful incidental association.
• Iron:- Gene TMPRSS6 (rs855791 and rs4820268)- Encodes key protein which regulates iron level in the body.

MicronutrientsTraining Recap:
• Ensure you are meeting your unique micronutrient needs by consuming fats that help aid in the absorption of fat-soluble micronutrients (foods rich in Vitamins A, D, and E).
• Pay attention to labels (many contain information on micronutrients).
• Natural food sources provide the best ways to absorb the vitamins and minerals needed to achieve optimal health and wellness.
• Supplementation can help counter a predisposition if food sources aren’t an option (key for those who are busy and travel).
