Why Optimal Multivitamin Chewable Works

Optimal Multivitamin Chewable is formulated by epigenetics expert Dr. Ben Lynch. It uses only superior and bioavailable forms of key nutrients. This unique formulation is based on supporting multiple enzymes in critical biochemical pathways.

Enzymes in these pathways require specific nutrients as cofactors. Two critical nutrient cofactors are the active and bioavailable forms of folate and B12. Your MTHFR gene converts and produces the active form of folate (5-MTHF) from whole foods.

However, MTHFR gene variations or lifestyle stress can slow down this gene, causing folate deficiency. It is estimated that over 50% of the population has a mutation in their MTHFR gene.

By supplementing with the natural form of folate as 5-methyltetrahydrofolate (5-MTHF), you bypass the MTHFR gene. This supports methylation by allowing folate to flow into the methylation pathway via the MTR enzyme.

Ironically, the artificial version of folate (folic acid) can further slow the MTHFR gene. This can even lead to folate deficiency! Folic acid is never included in any of Seeking Health’s dietary supplements.

Instead, we prioritize natural and bioavailable forms, including 5-MTHF (methylated) and methyl-free folinic acid. The antioxidant nutrients and herbs in Optimal Multivitamin Chewable promote healthy immune function.

It contains higher potencies of the antioxidants vitamins C and E than are typically found in chewable multivitamins. The carotenoid antioxidants lutein and zeaxanthin (from marigold flower) support eye health and vision.

This is particularly important with increased exposure to the irritating blue light emitted from screens. Antioxidants also promote a healthy response to oxidative stress. This, in turn, allows for optimal enzymatic function throughout the body.

Together the targeted nutrients and antioxidants in Optimal Multivitamin Chewable promote a healthy enzymatic environment, genetic expression, and countless health benefits.

The chewable tablets are ideal for those who have difficulty swallowing regular pills. For a higher-strength formula in capsules, consider Optimal Multivitamin Plus

Niacin Flushing

This formula contains niacin. When taken on an empty stomach, a healthy response to niacin supplementation may include mild blushing, warming, or tingling of the skin. This can appear on the ears, face, arms, torso, or occasionally on the legs. Commonly referred to as a "niacin flush", this harmless response normally dissipates within an hour. It is related to niacin's role in vasodilation (widening of blood vessels). Vasodilation leads to better circulation, capillary flushing, and increased blood flow to the surface of the skin. To minimize or prevent flushing, consider taking this supplement with food or in divided doses.
