What Happens If You Have A Gene SNP?

Some search terms matched

Genetic SNPs are tiny changes in your DNA that can drastically affect how well your enzymes and proteins work. For example, being homozygous for MTHFR C677T leaves that enzyme functioning at only about 30% efficiency, which can drain your energy and impair folate processing. Similarly, errors in SOD genes reduce your body’s ability to neutralize free radicals. While we can’t change your genes, we can work around them by identifying these weaknesses and filling the gaps with targeted nutrition and supplementation—helping your body function closer to its full potential.

Homocysteine is the Secret Assasin

Some search terms matched

Homocysteine is nasty — but here’s the truth no one tells you. It doesn’t kill you directly — it triggers white blood cells to release IL-8 and MCP-1, causing inflammation, kidney failure, heart attacks, and strokes. Most doctors don’t even check it anymore, thinking there’s no fix. But there is. Whether from 17 genetic SNPs or 12 vitamin deficiencies (like B6 or B12), you can address it by supporting your body’s ability to convert homocysteine into glutathione.

Remove inflammation by combatting High Homocysteine

Some search terms matched

High homocysteine levels can lead to inflammation, joint and muscle pain, and even shifting pain throughout the body. It’s also linked to birth defects and chronic kidney failure, and can raise blood pressure. Six genetic SNPs (like MTR, MTRR, and CBS) and MTHFR mutations (like C677T) can prevent homocysteine from converting into glutathione, which is essential for keeping inflammation in check. Plus, 12 vitamin deficiencies may temporarily raise homocysteine levels, so addressing these deficiencies is key.
