Gut Nutrients (previously Optimal GI)

Who Needs Optimal GI

Your gut health sets the stage for your overall health. Ensuring healthy digestion and absorption of nutrients is also one of the most powerful things you can do for your immune function. Optimal GI provides a blend of herbs and nutrients that synergistically support healthy digestion, GI barrier, and immune system function.

Optimal GI was formulated by epigenetics expert Dr. Ben Lynch. This unique formula supports digestive tract function with a powerful blend of nutrients along with soothing and strengthening herbs.

Optimal GI supports the following health benefits:

• An effective gut barrier
• Normal intestinal motility
• Digestive health and comfort
• Healthy connective tissues in the GI tract
• Healthy mucous membranes in the GI tract
• Regular bowel movements and waste elimination
• Healthy detoxification pathways
• A healthy gut microbiome

An unhealthy gut can contribute to digestive issues such bloating, constipation, diarrhea, and malabsorption. Moreover, many diseases of modern society are thought to be rooted in a leaky gut. If intestinal barrier function becomes compromised, it can trigger the ongoing activation of the immune system and inflammation. With over 60% of the immune system located in the gut lining, a healthy digestive system is also critical for immune health.

The gastrointestinal (GI) tract requires more than probiotics to support healthy digestion. Optimal GI contains traditional herbs, including marshmallow root, licorice extract (DGL), milk thistle, cat’s claw, aloe vera, turmeric, and slippery elm. It also contains targeted nutrients like N-Acetyl-D-Glucosamine and MSM that support gut lining health and function.

Each serving of Optimal GI provides 500 mg of citrus pectin. This natural fiber provides bulk to support healthy bowel movements. It promotes regular detoxification by binding to toxins. This formula is gluten-free and free of GMO-markers. Optimal GI is free from L-glutamine for those who do not tolerate it.

The convenient capsules provide a lower strength than our best-selling Optimal GI Plus powder. If you're ready to optimize your digestive and gastrointestinal wellness, talk to your healthcare team about Optimal GI.

What are the side effects of using Optimal GI Capsules?

Possible side effects include but are not limited to:

• Headache
• Dizziness
• Increased bowel movements
• Change in bowel consistency
• Stomach upset
• Absence of menstrual period
• Water and sodium retention
• Change in sexual function in men
• Vomiting
• Tingling of arms and legs
• Bloating
• Changes in energy levels
• Itching
• Worsening of allergy symptoms
• Yellow stools

In order to help reduce the instance of common side effects, consider consuming a lower quantity of capsules but more frequently throughout the day. According to Dr Lynch, this is a bit better tolerated than taking the full dose of capsules just once a day.

These side-effects are more likely if the recommended dosage is exceeded, if you are taking too high of a dose when first starting, or if taken on an empty stomach. Always take this product with food if you find that you may be sensitive to them on an empty stomach, and in divided doses throughout the day. Dr. Ben Lynch recommends starting with a small dose and only working your way up if needed.

Warnings

Consult with a healthcare professional before use if you are undergoing treatment for any medical condition or if you are using any medication(s), including NSAIDs.

Who is Testosterone Nutrients intended for?

Testosterone Nutrients is intended for adult men who want to support healthy testosterone levels, energy, stamina, and hormonal balance—especially as they age or experience symptoms related to low testosterone. It’s designed for those seeking a non-hormonal, nutrient-based formula that targets key pathways involved in testosterone production and balance, including adrenal health, DHEA metabolism, and oxidative stress.

This product may be particularly helpful for:

Men experiencing fatigue, low motivation, or diminished drive

Individuals undergoing physical training and seeking hormonal support

Those who want to support libido and reproductive health

Men interested in maintaining lean body mass and strength as they age

Testosterone Nutrients is not a testosterone replacement therapy (TRT) and does not contain synthetic hormones.

Does Testosterone Nutrients contain gluten or grains?

No. Testosterone Nutrients is free from gluten and grains. While some ingredients may be derived from highly purified plant sources such as rice or corn, the final product is processed to be free from grain proteins and allergens. It is also free from dairy, soy, artificial colours, flavours, and preservatives.

Does Testosterone Nutrients affect estrogen levels?

Testosterone Nutrients does not contain pharmaceutical aromatase inhibitors, but it includes nutrients like chrysin, DIM, and quercetin, which are studied for their ability to support healthy estrogen metabolism.† These ingredients help maintain a favourable testosterone-to-estrogen balance without fully blocking estrogen—a hormone that is still essential in appropriate levels. Always speak to your healthcare practitioner if you are concerned about hormone balance or estrogen dominance.

Is this product safe for individuals with adrenal or thyroid concerns?

This formula supports adrenal health with adaptogenic herbs like ashwagandha and nutrients like vitamin B6 and pantothenic acid, which are important for stress resilience. However, if you have an adrenal or thyroid condition, it's best to consult with your healthcare provider before use, especially if you are on medication or under ongoing care for hormonal health.

Can women take Testosterone Nutrients?

This formula was specifically designed for adult men. Women, especially those who are pregnant, nursing, or have hormone-sensitive conditions, should not take this product unless directed by a qualified healthcare professional.

Pro Tips for Best Results

Take in the Evening: Consume Testosterone Nutrients approximately 30–60 minutes before bedtime. This aligns with your body’s natural hormone rhythms and may support nighttime testosterone release.†

Use Consistently: Daily use is key for optimal results. Hormonal balance takes time—allow 4–6 weeks of consistent use to assess effectiveness.†

Support with Strength Training: Incorporate resistance or strength training exercises 3–5 times per week. Physical activity helps promote natural testosterone production.†

Follow a Protein-Rich, Whole-Food Diet: Focus on whole foods rich in protein, healthy fats (like omega-3s), and essential minerals like zinc and magnesium.

Limit Alcohol and Processed Foods: Alcohol and excess sugar can suppress testosterone levels and increase estrogen dominance. Choose moderation for better results.†

Track Your Progress: Monitor changes in energy, mood, strength, libido, and body composition. Keep a journal to track improvements.
