1. Protein Powders
Protein powders are one of the biggest segments of the supplement market. And there’s no shortage of options available. Animal-derived proteins such as whey, casein, and egg, as well as goat, beef, and fish, are extremely popular. But there’s also a healthy selection of vegetable-based proteins, such as rice, hemp, soy, and pea. You can even try hydrolysates, which are predigested whey and casein peptides.
Which powder to choose often comes down to personal preference and individual needs, but my favorite is whey protein isolate (WPI). It’s made from the water-soluble portion of milk that’s been processed and filtered to remove lactose, cholesterol, and fat and is preferred by many consumers who are lactose intolerant and/or have problems digesting protein powders. WPI is typically very high in protein content (usually 90% or more) in comparison with other forms, which can range from only 10–50% protein. It’s also high in L-cysteine and all nine essential amino acids (histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine). L-cysteine helps regulate blood sugar, decreases blood vessel inflammation, and reduces exercise-induced oxidative stress.
A great multivitamin/mineral complex should be the cornerstone of your nutritional plan. As a scientist, I always recommend foods first, but frankly no one is perfect, and the primary purpose of a multi is to fill the nutritional gaps in you diet of foods that you should be eating but aren’t.
A solid multi provides the most critical vitamins and minerals your body needs in optimal forms. The most important components include: vitamin A (my preference is for the beta-carotene and mixed carotenoids), the B vitamins, vitamin D (always look for the naturally occurring D3 form rather than the less potent D2 version), vitamin E (the tocopherol and tocotrienol forms are particularly important), vitamin C (look for the ascorbate form), vitamin K (those with cardiovascular and/or bone health concerns should consider taking the K2 form), calcium (the citrate form is my personal favorite), zinc, selenium, chromium, iodine, manganese, and molybdenum. Note: A good multi isn’t cheap—you get what you pay for.
Exercise research has shown that women who train intensely lose many critical vitamins and minerals, including B vitamins, vitamin C, chromium, selenium, zinc, iron, and magnesium. This primarily occurs through vitamin and mineral loss in sweat and urine, as well as increased uptake for energy production during exercise and recovery.
Keep In Mind: Choose a multi that provides less than 50 percent of the recommended daily amount in one capsule or tablet, then take one capsule or tablet with each of your two largest meals. Unless you have a specific health condition that mandates mega-doses of specific vitamins/minerals, don’t overdo it! Recent research has shown that high doses of some antioxidant vitamins can actually interfere with training adaptations.
There’s no shortage of products that pledge to help you burn more fat at a faster rate. But despite the hype, only a handful of ingredients have solid scientific evidence demonstrating a boost in metabolic rate, enhanced lipolysis (fat breakdown), and actual increases in fat oxidation (burning). On the list:
- 7-keto DHEA: This is a derivative of DHEA, but unlike the naturally occurring hormone it does not convert into testosterone or estrogen. Research has shown 7-keto supplementation may increase metabolic rate during dieting. Dosage: 100–200mg/day.
- Capsaicinoids: The molecules that give chili peppers their heat are also proven fat burners and metabolic boosters, according to numerous research studies. Dosage: 3–6mg/day.
- Green tea extract: Green tea is a natural fat burner, and an extract called EGCG may be particularly potent. It works best if you’re not also consuming caffeine on a regular basis. Dosage: 270mg/day standardized with EGCG.
- Yerba mate: This has long been used to help suppress appetite and burn fat. It usually contains caffeine. Dosage: 1,000mg/day.
- Advantra Z: This branded ingredient, derived from immature bitter oranges, may have some applications as a safe thermogenic aid. Dosage: 100mg/day of p-synephrine (the active component in Advantra Z).
- TeaCrine: Another branded ingredient and is a more recent newcomer to energy-boosting and weight-loss supplementation. Preliminary studies in humans have been positive, and unlike other stimulants, it doesn’t lose its strength or effectiveness during eight weeks of continuous use. Dosage: 100–200mg/day.
Keep In Mind: When it comes to fat-loss supplements, results vary widely among individuals, so don’t be discouraged if one of these ingredients leaves you hanging. Typically, combining several ingredients with different mechanisms of action (i.e., in a finished, research-proven formula) works best.
Tip: Divide your supplements with different meals for better absorption.
