Shaklee Proprietary Protein Blend
Also known as: Shaklee Proprietary Protein Blend, Life Shake Plant Protein, Shaklee Plant Protein Blend, Plant-Based Protein Blend
Overview
Shaklee Proprietary Protein Blend is a plant-based protein supplement designed to support muscle maintenance, weight loss, and overall health. While the specific protein sources are proprietary, it likely includes a combination of pea, rice, or soy proteins, enriched with leucine to enhance muscle protein synthesis. This blend is marketed as a meal replacement and weight management aid, particularly when combined with exercise. It is characterized by its lack of saturated fat and cholesterol, and is often fortified with essential vitamins and minerals. Research on plant-based proteins is extensive, indicating their effectiveness in supporting muscle growth and overall health, although specific studies on this proprietary blend are limited. The blend is derived from plant-based foods such as legumes and grains.
Benefits
Plant-based protein supplementation, especially when combined with resistance exercise, significantly enhances muscle strength and size. Meta-analyses show protein supplementation increases muscle strength (effect size ~0.2–0.5, p < 0.05) and muscle mass (effect size ~0.2–0.4, p < 0.05) in healthy adults. It may also support weight loss and fat mass reduction when used as a meal replacement, with some clinical studies suggesting notable fat loss and lean muscle gain over several months in structured programs. These benefits are most pronounced in adults engaging in resistance exercise training. While animal protein may have a slight edge, plant protein blends can be nearly as effective, especially when combined with leucine.
How it works
This protein blend stimulates muscle protein synthesis by increasing amino acid availability, particularly leucine, which activates the mTOR pathway, a key regulator of muscle growth. It primarily affects skeletal muscle but can also influence metabolic rate and satiety. Plant proteins generally have slightly lower bioavailability than animal proteins; however, blends combining multiple sources (e.g., pea and rice) can improve the amino acid profile and absorption. The blend interacts with the body by providing essential amino acids needed for muscle repair and growth, supporting overall metabolic function.
Side effects
Plant-based protein blends are generally safe for healthy adults. Common side effects include mild gastrointestinal discomfort, such as bloating and gas, in some individuals. Uncommon side effects may include allergic reactions in sensitive individuals, especially if the blend contains soy. Severe allergic reactions (anaphylaxis) are rare. No significant drug interactions have been reported. Contraindications include known allergies to any component of the blend, such as soy or pea. Individuals who are pregnant, breastfeeding, or have kidney disease should consult with a healthcare provider before using this supplement.
Dosage
For muscle protein synthesis, a minimum effective dose is approximately 20–25 g of protein per serving. Optimal dosage ranges from 20–40 g of protein per serving, taken 1–2 times daily, depending on individual dietary needs and exercise level. A maximum safe dose of up to 2 g of protein per kg of body weight per day is generally considered safe for healthy adults. It is best absorbed when consumed with a meal or post-exercise. The supplement is typically available in powder form and can be mixed with water or a milk substitute. No specific cofactors are required, but a balanced diet is recommended.
FAQs
How should I use this protein blend?
It can be used as a meal replacement or post-workout supplement. Mix with water, milk, or plant-based milk. Adjust the amount of powder to achieve your desired protein intake.
Is this protein blend safe?
Generally safe; monitor for allergies if sensitive to plant proteins. Start with a small dose to assess tolerance. Consult a healthcare provider if you have underlying health conditions.
When is the best time to take this protein blend?
Best taken post-exercise to aid muscle recovery or as a meal replacement to support weight management and satiety. Consistent timing can help optimize results.
What results can I expect?
Expect modest increases in muscle strength and size, support for weight loss, and muscle retention with consistent use and exercise. Individual results may vary based on diet and activity level.
Is plant protein as effective as animal protein?
While animal protein may have a slight edge, plant protein blends can be nearly as effective, especially when combined with leucine. Ensure a balanced amino acid profile for optimal results.
