Dry Eye Relief: Comparing Lacritec and DRYeye Forte

As experienced optometrists, we frequently receive questions regarding whether nutritional supplements can genuinely improve eye health or alleviate chronic symptoms associated with various eye conditions. Adequate nutrition plays a significant role in supporting eye health, particularly in the context of dry eye disease, where targeted nutrition and supplementation can yield remarkable benefits.

A wealth of clinical studies consistently shows that a balanced diet, alongside specific supplements, can enhance tear quality, reduce inflammation, and promote lasting comfort in the eyes. This compelling evidence highlights the importance of integrating supplements into a holistic management strategy for effectively tackling dry eye symptoms.

Two popular supplements in this arena are Lacritec and DRYeye Forte. While both products aim to alleviate symptoms of dry eye, they differ significantly in their formulations, potency, and the efficacy of their ingredients once absorbed by the body.

This comparative analysis clarifies these differences, empowering you to make a well-informed decision regarding your approach to managing dry eye symptoms effectively.

Comprehensive Ingredient Analysis for Lacritec and DRYeye Forte

Essential Ingredients Found in DRYeye Forte

• 667 mg of re-esterified omega-3 triglycerides per capsule
  • 240 mg of EPA
  • 160 mg of DHA
• 455 mg of borage oil containing 100 mg of GLA

Recognising the Role of Different Omega-3 Fatty Acids in Eye Health

Although both supplements contain omega-3 fatty acids, it is vital to understand that not all omega-3s work the same way within the body.

Lacritec uses flaxseed oil, which provides ALA. While ALA is known as an omega-3 fatty acid, the human body only converts a small percentage of ALA into the more essential forms needed for alleviating dry eye symptoms, specifically EPA and DHA. Research indicates that conversion rates of ALA to EPA are roughly between 8% and 12%, with the majority of ALA being used as an energy source rather than for supporting eye health.

In contrast, DRYeye Forte supplies EPA and DHA directly, employing higher concentrations in a re-esterified format. This advanced manufacturing method improves both absorption and bioavailability, ensuring that a larger portion of the active ingredients effectively reaches the tissues where they are most required.

When comparing the effective levels of EPA and DHA:

• Three capsules of DRYeye Forte offer a significantly higher amount of EPA and DHA compared to three capsules of Lacritec.
• To obtain the same EPA and DHA content found in three capsules of DRYeye Forte, you would need to consume approximately six Lacritec capsules.

Both supplements recommend starting with three capsules daily during the treatment phase, making this difference clinically relevant for individuals seeking effective relief.

Evaluating the Quality and Sourcing of Fish Oil in Eye Health Supplements

Both Lacritec and DRYeye Forte are manufactured in Australia, utilising high-quality fish oils sourced from small, cold-water fish such as sardines and anchovies from Peru. Smaller fish generally accumulate fewer toxins, making them a safer option for supplementation. Both oils undergo stringent purification and deodorisation processes to remove impurities and minimise any unpleasant fishy aftertaste.

DRYeye Forte employs re-esterified triglyceride fish oil, which has shown superior absorption compared to traditional ethyl ester forms. This innovation not only improves consistency but also decreases gastrointestinal discomfort for many users, making it a preferred choice.

Investigating the Benefits of Vitamin D and Vitamin E for Eye Health Improvement

A notable difference between the two supplements is that DRYeye Forte contains both vitamin D3 and natural vitamin E in its formulation, which can significantly enhance eye health.

Uncovering the Positive Effects of Vitamin D3 on Eye Health

Research indicates a strong correlation between low vitamin D levels and symptoms of dry eye. Studies suggest that vitamin D may:

• Reduce ocular inflammation
• Improve tear stability
• Support the healing of the ocular surface
• Alleviate light sensitivity and general ocular discomfort

Recognising the Diverse Benefits of Vitamin E

Vitamin E serves a crucial dual role. It not only offers antioxidant and anti-inflammatory benefits but also protects omega-3 fatty acids from oxidative damage. Extended fish oil supplementation can increase the body's requirement for vitamin E, making its inclusion essential for maintaining balance and optimising omega-3 metabolism.

In contrast, Lacritec does not include vitamin D3 or vitamin E, which may limit its overall effectiveness in supporting eye health.

Evaluating the Safety and Tolerability of Omega-3 Supplements for Eye Health

Both supplements are generally well tolerated when used according to the recommended dosage guidelines.

Potential side effects from either product may encompass mild gastrointestinal disturbances such as reflux, bloating, or loose stools. These effects typically depend on the dosage and can vary from person to person.

Individuals taking anticoagulant medications or those with bleeding disorders should seek guidance from a healthcare professional before beginning either supplement.

Due to the presence of vitamin D3 in DRYeye Forte, individuals with hypercalcemia, kidney disease, or conditions influenced by vitamin D should consult a healthcare expert before use. In such cases, Lacritec may be the more suitable choice due to its lack of vitamin D.

As with all supplements, it is advisable to consult a healthcare provider if you are pregnant, breastfeeding, or managing chronic health conditions.

Choosing the Most Appropriate Supplement for Managing Dry Eye Symptoms

For the majority of individuals experiencing moderate to severe dry eye disease, DRYeye Forte offers more comprehensive and targeted support. This is due to:

• Higher concentrations of effective EPA and DHA
• Improved absorption through the utilisation of re-esterified fish oil
• Inclusion of vitamin D3 and vitamin E, which aid in reducing inflammation and promoting tear production

Lacritec may still be suitable for those with very mild symptoms or for individuals who cannot tolerate vitamin D supplementation.

Expert Insights and Recommendations for Effective Management of Dry Eye Symptoms

Both supplements can positively influence the management of dry eye symptoms; however, they are not interchangeable.

DRYeye Forte provides higher therapeutic dosages of the most effective omega-3 fatty acids, along with additional nutrients that assist in managing inflammation, improving tear quality, and supporting the health of the ocular surface. Many patients experience more effective symptom relief with fewer capsules required per day.

Ultimately, the most suitable supplement is one that seamlessly integrates into a personalised dry eye treatment strategy. If you are uncertain about which product best aligns with your needs, we recommend consulting your optometrist or healthcare provider for tailored advice.

Lacritec vs DRYeye Forte Commonly Asked Questions

Which supplement provides superior relief from dry eye symptoms: Lacritec or DRYeye Forte?

For the majority of individuals suffering from moderate to severe dry eye symptoms, DRYeye Forte stands out as the more effective option. It contains elevated levels of EPA and DHA, the active omega-3 fatty acids known to reduce inflammation and improve tear quality, along with vitamin D3 and vitamin E for enhanced support. Lacritec may still provide benefits in milder cases or when vitamin D supplementation is not advised.

What are the key differences between Lacritec and DRYeye Forte?

The primary distinction lies in their formulations and overall potency. DRYeye Forte features highly bioavailable re-esterified fish oils that deliver clinically relevant doses of EPA and DHA, complemented by vitamin D3 and natural vitamin E. Conversely, Lacritec utilises flaxseed oil, which offers ALA — an omega-3 source that is less effective and has limited conversion into EPA and DHA.

How many Lacritec capsules are needed to match the EPA/DHA dosage found in DRYeye Forte?

To achieve equivalent levels of EPA and DHA contained in three capsules of DRYeye Forte, one would need to consume approximately six Lacritec capsules. This requirement arises from Lacritec's lower omega-3 concentration and its reliance on ALA, which only partially converts into the more bioactive forms necessary for the body's needs.

Is it safe to use DRYeye Forte if I have kidney issues or elevated calcium levels?

If you have kidney disease or hypercalcemia, it is essential to consult your healthcare provider before starting DRYeye Forte. The inclusion of vitamin D3 may not be suitable for individuals with these conditions. In such cases, Lacritec, which does not contain vitamin D, may be the more appropriate alternative.

Will I need to take dry eye supplements indefinitely?

Not necessarily. Many individuals begin treatment with a higher dosage (three capsules daily) for 6–8 weeks, after which they can reassess their condition with their optometrist. Some may transition to a maintenance dosage or discontinue use altogether if their symptoms improve. However, ongoing supplementation may be beneficial for chronic or seasonal dry eye, particularly if there are underlying issues such as inflammation or dysfunction of the oil glands.
