Genex Formulas TMG is a dietary supplement made from Betaine Anhydrous, which is also called Trimethylglycine or TMG. Each capsule contains 1000mg of this active compound. The product comes in a 120 capsule bottle, which gives you a four month supply at one capsule daily.
The brand markets this supplement as a liver support and methylation booster. It is built for people who want clean methyl donors without fillers or synthetic additives. The capsules are easy to swallow and have no strong taste.
What sets this product apart is the NSF Certification. This is a gold standard in the supplement industry. NSF tests every batch for purity, label accuracy, and contaminants. Most TMG brands skip this step. Genex makes it a core part of their quality promise.
The product is also gluten free, non GMO, and free from soy, dairy, and artificial colors. This makes it a safe option for sensitive users.
How TMG Works In Your Body
TMG is a natural compound found in foods like beets, spinach, and quinoa. Your body uses it as a methyl donor, which means it gives away methyl groups to power thousands of chemical reactions. These reactions include DNA repair, hormone production, and detox.
One of the most important jobs of TMG is converting homocysteine back into methionine. High homocysteine levels are linked to heart disease, stroke, and cognitive decline. By donating a methyl group, TMG helps keep your homocysteine in a healthy range.
TMG also acts as an osmolyte. This means it helps your cells hold the right balance of water and protect themselves from stress. This function is helpful for liver cells and kidney cells, which deal with toxins every day.
When you take NMN or NAD+ boosters, your body uses up methyl groups fast. Adding TMG replenishes that supply. This is why many longevity experts recommend stacking TMG with NAD+ supplements.
Genex Formulas Brand Background
Genex Formulas is a US based supplement company that focuses on anti aging and wellness products. The brand makes its products in GMP certified facilities and tests each batch for purity. Their lineup includes NMN, Resveratrol, NAD+, and TMG.
The company has built a strong reputation on Amazon and through its own website. Many of their products carry NSF Certification, which is rare for a small brand. This shows they invest in quality control.
Their customer service is also well rated. Users report fast shipping, helpful responses, and a clear refund policy. The brand offers a 30 day satisfaction guarantee on most products, which removes risk for new buyers.
Genex positions itself as a science based brand. Each product page explains the active ingredient, the dose, and the research behind it. This kind of transparency is helpful for buyers who want to make informed choices.
The brand has been growing fast in 2025 and 2026 because more people are stacking TMG with NMN for longevity goals.
Main Benefits Of Genex Formulas TMG
The first benefit is homocysteine support. Studies show that betaine can lower homocysteine by 10 to 20 percent in just a few weeks. This may help protect your heart and blood vessels.
The second benefit is liver support. TMG helps the liver process fats and remove toxins. Research links betaine intake to lower liver fat and better liver enzyme levels in people with mild fatty liver.
The third benefit is better methylation. Methylation drives DNA repair, mood balance, and energy production. People with MTHFR gene mutations often have low methylation. TMG can give them a steady supply of methyl groups.
The fourth benefit is athletic performance. Some studies show that 2.5 grams of betaine per day can improve muscle power and endurance. Lifters and athletes use TMG for this reason.
The last benefit is mood and focus support. Many users report calmer mood and sharper thinking after a few weeks. This may come from better methylation of neurotransmitters like serotonin and dopamine.

Double Wood Supplements TMG offers 180 capsules at 1000mg per serving with third party testing. It is a great pick for buyers who want a higher capsule count at a fair price.
NOW Foods TMG 1000mg is a trusted name in the supplement world. The brand has decades of experience and uses tablets instead of capsules, which some users prefer.
Nutricost TMG 750mg gives a slightly lower dose at a budget price. It is a smart choice for new users who want to start with a smaller serving and adjust over time.
All three brands have strong reputations and clean labels. Your choice may come down to dose, format, and price per serving.
Ingredients And Label Transparency
Genex Formulas TMG keeps the label simple. The only active ingredient is Betaine Anhydrous (Trimethylglycine) at 1000mg per capsule. There are no proprietary blends, no hidden fillers, and no synthetic dyes.
The capsule shell is made from vegetable cellulose, which makes it suitable for vegans and vegetarians. Other inactive ingredients include rice flour and magnesium stearate, both of which are common and safe at small amounts.
The label clearly lists the serving size, the active dose, and the full ingredient list. This kind of transparency is rare in the supplement space. Many brands hide low doses inside proprietary blends.
The NSF mark on the bottle is your proof that the label matches what is inside. NSF tests for heavy metals, microbes, and ingredient accuracy. If a product passes, it means you get exactly what the label promises.
This level of testing adds confidence for anyone who takes supplements long term.
Dosage And How To Take It
The standard dose for TMG is between 500mg and 3000mg per day. Genex Formulas offers two strengths, 500mg and 1000mg, so you can pick the dose that fits your goals.
For general wellness, one 1000mg capsule a day is enough. If you take NMN or NAD+ boosters, you can add a second capsule to support methylation. Athletes and people with high homocysteine may take up to 3 capsules daily, but only after talking with a doctor.
The best time to take TMG is with a meal. This helps with absorption and reduces the chance of stomach upset. Many users take it in the morning with breakfast for a steady energy effect.
You can split the dose if you take more than one capsule. For example, take one with breakfast and one with lunch. Avoid taking TMG late at night, as some users report mild stimulation that can affect sleep.
Always start with the lowest dose and build up slowly. This gives your body time to adjust.
Side Effects And Safety Profile
TMG is well tolerated by most people. The most common side effects are mild and digestive in nature. These include nausea, bloating, loose stools, and stomach cramps. They usually go away after a few days.
High doses above 9 grams per day may raise LDL cholesterol in some users. Stay within the 1 to 3 gram daily range to avoid this risk. Most people will never need that much.
People with kidney disease or trimethylaminuria should avoid TMG. The body breaks down betaine into compounds that can build up in these conditions. Pregnant and breastfeeding women should also skip TMG unless their doctor approves it.
TMG may interact with certain medications, including some used for high homocysteine. Talk to your doctor if you take prescription drugs.
Genex Formulas TMG itself has very few complaints. The NSF certification means you avoid the contamination risks seen in cheaper brands. Stick to the label dose, and most users will have no issues at all.
Real Customer Reviews And Feedback
On Amazon, Genex Formulas TMG holds a 4.5 star rating with over 500 reviews. The product also has a 4.84 star rating on the brand website. These numbers show steady customer satisfaction over time.
Positive reviews mention better energy, calmer mood, lower homocysteine on lab tests, and improved digestion. One user wrote that their homocysteine dropped from 14 to 8 after two months of daily use. Another shared that their liver enzymes returned to normal range.
Many buyers also praise the clean capsule and easy swallow size. The bottle is sturdy, and the seal is tight. Shipping is fast for Prime members.
Negative reviews are few. Some users say the capsules have a slight smell, which is normal for betaine. A few mention mild stomach upset in the first week, which usually fades.
Overall, the feedback is strong and consistent. Most buyers say they would order again, which is a sign of a quality product.
Genex Formulas TMG vs Other Brands
Compared to Double Wood Supplements TMG, Genex offers a higher single capsule dose but a smaller bottle. Double Wood gives you 180 capsules while Genex gives 120. Genex wins on NSF certification, which Double Wood does not carry.
Compared to NOW Foods TMG, the dose is similar at 1000mg. NOW uses tablets that are larger and harder to swallow for some users. Genex capsules are smaller and easier to take. The price is close between both brands.
Compared to Nutricost TMG 750mg, Genex offers a higher dose per serving. Nutricost is cheaper per bottle, but the cost per gram of TMG is similar. Nutricost is a budget pick, while Genex is a premium option with stricter testing.
If quality and certification matter most to you, Genex Formulas is the strongest pick. If price per bottle is the main factor, Nutricost or Double Wood may suit you better.
Price And Value Comparison
The 120 capsule bottle of Genex Formulas TMG sells for around 30 to 40 dollars on Amazon, which works out to roughly 25 to 33 cents per capsule at 1000mg. This is a fair mid range price for a TMG supplement.
When you factor in the NSF certification, the price becomes very reasonable. NSF testing adds cost for the brand, and few competitors carry this seal. You are paying for verified purity.
The 360 capsule version offers better value per serving. It costs more upfront but lasts a full year at one capsule a day. This is the better choice for long term users who plan to stick with TMG.
Compared to premium brands like Life Extension, Genex is more affordable. Compared to budget brands like Nutricost, Genex costs more but offers higher quality control. The brand sits in a sweet spot for quality and price.
Who Should Use This Supplement
This supplement is a good fit for several groups. The first group is people with high homocysteine levels. If your blood work shows elevated homocysteine, TMG can help bring it down.
The second group is NMN and NAD+ users. These supplements use up methyl groups in your body. TMG replaces those methyl groups and keeps your methylation cycle running smoothly.
The third group is people with MTHFR gene mutations. These users often have low methylation by nature. TMG offers an easy way to support methyl group supply without prescription drugs.
The fourth group is athletes and lifters. Studies show that betaine can boost muscle power, strength, and endurance when taken at 2.5 grams a day.
The last group is people who care about liver health. If you drink alcohol, take medications, or have mild fatty liver, TMG can help your liver function better. Always check with your doctor before starting any new supplement.
Pros And Cons Summary
The biggest pro is the NSF certification, which proves the product meets strict purity and label standards. This is rare in the TMG market and adds real value.
Other pros include the 1000mg high dose per capsule, the clean ingredient list, the vegan friendly formula, and the strong customer reviews. The brand also offers a 30 day satisfaction guarantee, which lowers buying risk.
On the con side, the price is higher than budget brands. People on a tight budget may find Nutricost or Best Naturals more affordable. The bottle holds 120 capsules, which is fewer than some 180 or 240 count competitors.
Some users may not like the slight smell of the capsules, which is natural for betaine. This is not a quality issue but a personal preference.
Overall, the pros far outweigh the cons. For most buyers who care about quality and purity, this is one of the best TMG choices in 2026.
Final Verdict On Genex Formulas TMG
