NAC (N acetylcysteine)

Powerful antioxidant support for detoxification and cellular health

NAC provides a potent 500 mg dose of N-Acetyl L-Cysteine (NAC), a well-researched amino acid derivative that plays a central role in the body's antioxidant defence system and natural detoxification pathways.

NAC is best known as a direct precursor to glutathione, one of the body's most important antioxidants, helping to replenish and maintain levels that are essential for protecting cells against oxidative stress, environmental toxins and the effects of everyday metabolic activity. NAC is ideal for those seeking expert-grade nutritional support to boost detox pathways and promote long-term vitality.

How NAC Supports Your Health

• Supports glutathione replenishment -NAC is a key building block for glutathione synthesis, helping the body maintain adequate levels of this critical intracellular antioxidant.

• Supports detoxification pathways - By promoting healthy glutathione levels, NAC helps the body neutralise and clear harmful substances, including environmental toxins and metabolic byproducts.

• Supports liver function - NAC has been widely studied for its role in supporting healthy liver function and protecting liver cells from oxidative damage.

• Supports respiratory health - NAC supports the integrity and function of the respiratory tract, making it a valuable nutrient for overall lung and airway wellness.

Biofilm disruptor - NAC plays an important role in gut health and gut dysbiosis.

Spike Protein Detox - NAC is a mucolytic, useful for both acute respiratory infections like COVID as well as post-covid fatigue syndrome, or Long COVID.

Who is this program suited to?

FIT40 is designed for men and women between 35–55 years old looking for a metabolic reset, better hormonal balance, or want to take proactive steps to attain better energy, improved gut health or prevent cognitive and physical decline.

Who should NOT do this program?

This program is not suitable for women who are currently pregnant or breastfeeding. We also recommend consulting your doctor before starting if you have any serious medical conditions

Can both men and women do FIT40?

Yes. FIT40 is tailored to both men and women. While the hormonal and metabolic shifts of midlife look different for each, the foundations of the program nutrition, gut health, movement, nervous system regulation and daily reflection are equally relevant and effective for everyone.

How much does FIT40 cost and what is included?

FIT40 price is listed above and includes everything you need to get started and stay supported:

• Your FIT40 hardcopy journal, delivered to your door — beautifully designed for daily reflection, tracking and habit-building, away from screens (hardcopy only available in South Africa, if outside of SA its available online / or printable form)

• 12 months access to the FIT40 online hub

• All resources within the hub, including meal plans, shopping lists and recipes

• Breathwork and movement guides

• All ongoing program content and updates

This is a once-off investment in the second half of your life.

Is there a consultation involved?

No. FIT40 is an online self-guided program and does not include a consultation with a healthcare provider. If you have specific health concerns or would prefer personalised guidance, we recommend speaking with an integrative or functional medicine practitioner before starting.

Does the program include supplements?

Certain supplements and functional foods are suggested as part of the program, but none are mandatory. Where supplements are suggested, these are well-known, generally well-tolerated options that can support your results. Any choices around supplements are made at your own discretion.

Will I need a lot of time each day?

No. FIT40 is designed to fit into real life. The daily check-ins, journaling and breathwork practices are intentionally concise — most days require no more than 20–30 minutes of focused attention, plus whatever movement you choose to incorporate.

What do I need to get started?

Very little - most of what you need you likely already have at home:

• A yoga or workout mat

• Access to Spotify or Apple Music

• A glass or stainless steel water bottle (please avoid plastic)

Optional extras — don't rush out and buy these now, see how you go first:

• Weights / weighted-vest

• A Bluetooth speaker

Can I buy the program now and start it later?

Yes, absolutely. Once you purchase FIT40, you can begin whenever you feel ready. You will have access to all program content for 12 months from the date of purchase, so there's no pressure to start immediately.

Do I have to complete all 40 days?

The full 40-day program is designed to give you the most meaningful results, but it is not mandatory to complete every single day. You can move at your own pace.

What preparation is required before I start?

Very little. The first few days of the program ease you in gently, giving you all the information you need before the full program begins. You'll receive clear guidance on nutrition, movement, breathwork and daily habits — everything is laid out step by step so you always know what to do next.

Is it a plant-based or vegan diet?

No. The nutritional guidance within FIT40 focuses on a low-inflammatory way of eating rather than a specific dietary label. If you are vegan or vegetarian, you can absolutely still do the program — the principles apply regardless of your dietary preferences.

Will I lose weight on FIT40?

Weight loss is a common side effect for many participants, particularly as inflammation reduces and metabolism improves. However, FIT40 is not a weight loss program — it is a vitality program. The focus is on how you feel: your energy, your hormones, your clarity and your relationship with your own body. Weight tends to follow naturally when those foundations are in place.
